The Soviets requested that a chemistry department for experiments with rocket fuels be attached. Huber Emrich was delega*ed to establish the department. He merely pretended to be an expert in the field of rocket fuels by showing to the Soviets original documents of the B1W Plant bearing his signature as a department chief. Subsequently it was learned that Emrich had signed these documents after the fact instead of the actual department chief, Borovski (fnu) (phonetic spelling). In order not to be exposed as a swindler, Emrich consequently planned not to hire any fuel specialists for the department. Before the German experts were deported from Halle to the USSR, they did no practical work but tried to familiarize themselves with this new field. Actual research work was started after their deportation to the USSR. Primarily the Halle Labor Office had been in charge of hiring personnel for the Chemical Group. 1 In Halle, Emrich and RoessingT were assigned to Colonel Vlassov. But Roessing prepared the workorders for the Chemical Department. This arrangement was suggested by Emrich who feed exposure if he were subordinated to Roessing directly. 4r!4Nwt Ika^wv Then Colonel Vlassov returned to the USSR, he said he preferped work at the Ministry of Aviation to a director's position at an aircraft plant. He explained to some German experts that the first director of a new plant had a dangerous position, because the circumstances would make it impossible to fulfill the production quota and he would soon be treasferred, possibly to a convict camp, and be charged with sabotage. The sesend digester would net be much better off, and only the fourth Of fiftk director wotild be comparatively safe, because, by thus, the diffiouitissxxwoul4 have been eliminated. After his arrival to Pedbez'os.l, Ear .ch wanted to be assigned with his department to the Ministry of Chemistry, CLASSIFICATION CONFIDENTIAL Approved For Release 2008/07/18: CIA-RDP80-00810A006100770001-2 55 25X1- Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 This Wit, however, decided that the department had been established on request of the Ministry of Aviation which, therefore, would also be responsible of it. During their time at Podberez)[e, the chemical group was controlled by 0KB II. No work pattern or program was used for the activities of the Department of Chemistry. The slow work procedure of 0KB II and the lack of the required laboratory equipment made it necessary for the individual work orders to be decided upon according to the circumstances. The entire laboratory equipment, even laboratory tables and improvised test stands, had to be produced partly of make-shift material. -Assistance from the Ministry of Chemistry was not obtained. Most of the personnel had still to familiarize themselves with the field of rocket fuels, and to prepare the basic records which were lacking. Due to these handicaps, no result were probably obtained to exceed those obtained by related German expert groups during the war. The activities included the following: Advisory work in the field of materials for both 0KB I and II Work on the DFS-346 rocket aircraft Development work in the field of rocket fuels :Miscellaneous activities 4. Advisory work in the field of material problems included the analyses of materials used by both OKBs and the change-over from German materials to Soviet products. The analyses of steel, light metal, oil, gasoline, lubricants and varnishes followed the instructions and specifications given by Soviet manuals for aviation materials. These specifications were so detailed and foolproof that even inadequate personnel was able to make correct analyses. No details were available or the material analysed. "ork for the DFS-46 included 10 projects: a. Project for the establishment of a research institute for rocket fuels to include a laboratory, a technical institute and storage facilities. The laboratory building was to house sections for inorganic analyses, for organic preparations. electrical chemistry, physics and physical chemistry and for spectral analyses. A test stand fitted with a small combustion chamber, and equipment for the measurement of ignition delays was also planned. The project also included a small rubber laboratory and equipment for experiments with powder charges. The main technical institute was to be provided for the production of organic substances in quantities up to 200 kg. Among other equipment' a distillation c?dom, 10 meters high, was to be installed. Storage facilities were to be constructed for "Salbei" (code for an oxidizing agent consisting of concentrated nitric acid) "T-Stoff" and similar agents. The project covered details such as laboratory tables, funnels, etc. and was primarily designed to suit the members of the Department of Chemistry. The plan, however, was never carried out and improvised equipment was installed in the available buildings. Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 b. Production specifications for rubber mixtures on a Lupolen and Oppanol basis (Lupolen - code for a type of sealing material used on fuel lines) Oppanol - a synthetic material equivalent to Vestanex, composed of isobutylene and isoprene), to resist T-Stoff and Salbei, and specifications for single parts, such as socket hoses and gwivel hoses for fuel, especially for T-Stoff. These specifications were prepared for the production of vulcanized Buna S blends (synthetic rubber) with Lupolen admixtures and especially for the production of Oppanol and Lupolen. Lupolen -Oppanol mixture at a ratio of 50 to 50 and 30 to 70 was to be used as packing agent. A 15 to 85 mixture was recommended for the production of hoses. PeCe fabric (a type of highly acid resistant nylon- like fabric of low melting point produced by I.G. Farben) with a coating of Oppanol sulution was used as material for the hoses. The inner and outer coil of the fuel hoses were to be made of pure aluminum or V2A type steel. The fuel lines to tap the tanks ,,swivel hoses), however, were to be made only of one layer of Pe Ce fabric coated with Oppanol solution. In 1948 and 1949, Soviet firms produced seals and hoses according to these specifications. These products proved to be sufficiently resistant against T-Stoff and C-Stoff, as well as against Salbei. After 1949, the Soviet material was equal in quality to the captured German material. c. Stabilization of C-Stoff. C-Stoff containing about 50 percent of hydracine hydrate, 37 percent methanol and 3 percent of a 10 percent aqueous solution of potassium copper cyanuer, dissociated when stored. Since none of the chemists was experienced with C-stoff, the type of dissociation had first to be analyzed in order to find a preventive agent. It was found that the dissociation was a result of an oxydizing process of the hydrazine hydrate which in turn was effected by oxygen and catalytically forced by the content of calium copper cyanuer because the latter addition did not contain the theoretically required amount of cyanogen. The defect was eliminated by sealinS the C-Stoff against air by covering it with a layer of transformer oil and by adding 0.05 to 0.1 percent of hydroquinone which sufficiently eliminated the catalytical oxydation without increasing the ignition delay. The maximum ignition delay for C-Stoff and T-Stoff mixtures was 25 milli seconds. In addition to the above mentioned mixtures, others containing more methanol or water were used to reduce the temperatures in the combustion chamber. d. Experiments with a static measuring instrument for ignition delays. In cooperation with Dr. ', lehde's department, the Chemical Group developed a measuring instrument for ignition delays to test rocket fuels. One component was dripped into t'.,e other and the time passed between the impingement of the drop ;grid the inflammation was measured in D}illi seconds. One agent, for example C-Stoff, was wed in a small crucible with a capacity of about 2 cm3 made of V2A steel or porcelain, Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 and small drops of T-Stoff were added by means of a small pipette. The impingement on the liquid surface produced an impulse which caused a condenser to discharge. As soon as the reaction of both components occured, the flame produced stopped the discharge by means of a photoelectric cell. The remaining tension of the condenser indicated the delay in milli seconds on a calibrated scale. ~. Development of a cabin heater operating without exhaust gases. The designers believed that, because of the low temperatures at the high altitudes reached by the DFS-346, the cabin should be heated. It was planned that the heat be produced by burning pressed tablets of an aluminum-magnesium powder in an oxygen flow. The stove, an iron tube, about 60 cm long and 10 cm in diameter, was fitted with ribs and with an iron rod. The latter extended over the length of the tube and was to hold the tablets which were provided with a hole for this purpose. Aluminum and magnesium powder at a mixture ratio of 2 to 1 was mixed with diluted water glass. This paste was pressed into tablets and burned in a kiln at a temperature of approximately 100? centigrade. Ignition was effected by the first tablet on the rod which was made of a thermite substance with a cast-in ignition coil which, being fed from the aircraft battery, started to glow and ignited the thermite. By feeding oxygen into the tube, the other tablets started to burn. The heat was controlled by the oxygen flow. A blast unit was to blow cold air to the stove. Heated air wbuld flow back to the cabin at a temperature of 60 dentigrades. The burning period of the stove was one hour. After small technical difficulties were eliminated the stove operated satisfactorily, but it was never installed in the DFS-346, since friction of the air occuring at high speeds actually produced enough heat for the cabin. f. Experiments for tight riveting of Salbei containers. The weld*dg seams of the aluminum tanks were not resistant enough against Salbei. Similar effects were observed on V2A steel containers. In order to eliminate these defects, small tightly riveted tanks, about 40 em high and 30 cm in diameter, with riveted bottoms and one longitudinal seam were produced. One of the bottoms was provided with a flange and could be sealed with a lid. PeCe fabric with an Oppanol coating was used as packing material for the parts to be riveted. For experimental purposes, these tanks were filled with Salbei and stored under pressure. After a period of six wonths, the packing material started to disintegrate by swelling and crumbling. The next tanks were, therefore, riveted at a smaller spacing with the overlying inner edge slightly rimmed to protect the packing material. Some sort of duraluminum, 2 mm thick, coated with a layer of 2/10 mm pure aluminum proved. to he the best suited material for these tanks. No satisfactory results were obtained in vibration tests. The leakages, however, were so low that these type of fuel tanks were still considered for operations. The same riveting system was allegedly also applied for the P-150 tanks. After Dr. Daniel (fnu) was repatriated these activities were discontinued.

(1; The hydrazine hydrate content was determined by using iodinepotassium iodine solution (sic). (2) The methanol content was determined from the specific gravity obtained ir_ a pyknometer. A diagram was prepared giving the pyknometric measurements in relation to the content of hydracine hydrate and the content of methanol. (Screening analyses) (3) The content of water was determined as a difference by computation. (4) The copper content was determined in the residues after evaporating C-Stoff according to a usual system. (5) Hydrocyanic acid was acidified with sulphuric acid and overdistilled, and the content in the distillate determined titrimetii,ly with silver nitrate solution. h. T-Stoff analyses. The content of H202 was determined according to the methods usually applied by titration with potassium permanganate. In about early 1950, when Soviet produced-T-Stoff was received, the Department of Chemistry was also given pertaining analyzing methods. From Russian translations of American literature on German T-Stoff, it was learned that the Soviet T-Stoff was equal in quality to the German product used for submarines. The analyses were made to determine the following: H202 content Total phosphate content The impurity content (by filtration) The reaction to a 24-hour heating to 90 centigrades in a special apparatus, to test storage possibilities. The loss of H202 was not to exceed 3 percent. i. Phydlcal-chemical calculations on rocket fuels. These calculations, made by individual members of the group, were required as basis records for work in the field of rocket fuels. The activities included thermodynamic calculations of rocket fuels handled by Dr. Dunken (fnu); calculations of combustion chamber temperatures, calculations of the thrust obtained by various compositions of C-Stoff, the percentage of methanol and water, the ratio of these two components, T-Stoff and water, Petroleum and Salbei and petroleum and T-Stoff.

This geld when passed through a fine wire mesh gave the petroleum thixotropy properties. n addition of 0.3 to 0.5 percent sebacic salts proved to be sufficient. According to the above mentioned priniple, a production process in_volvin the production of bbbacic salts of fatty acids dissolved in petroleum proved to be very advantageous. This was effected automatically at a temperature of 160 centigrades by adding sodium hydroxide dissolved in methanol. The methanol was distilled during this process. In addition to the usual viscometric methods to measure thixotropy, another system was applied which involved a special measuring instrument built of captured material. The thixotrope petroleum to be measured was filled into a small container which was rotated by a small engine. The thixotropy petroleum moved a plate suspended from a torsion wire to an angular deflection, until the viscosity of the geld was overcome by the power of the torsion wire. The plate came to a rest while the container continued to rotate. The constant angle of deviation indicated the thixotropy. Another system involved a neutral powder such as calcium carbonate or fine grain sand evenly mixed into the thixotropy petroleum. Time and quantity of the settling powder indicated the thixotropy. e. Production of an A-type fuel of sodium powder and petroleum. The petroleum was absorbed and the powder was carefully mixed with thixotropic petroleum, ft;em_,:thec?Petro1eum suspended sodium powder mentioned in paragraph 6 c above. The small ball shaped sodium particles were not to be flattened so their diameter remained unchanged. An about 25 to 30 percent suspension of sodium in petroleum, designated PENA, was obtained in this process. 2_-T1pe fuel was obtained by diluting PEINA with thixotropy petroleum until the sodium content was finally reduced to 3 percent. The thixotropy of the petroleum prevented the sodium from settling. Even under a comparatively low pressure, this type of fuel could be fed like a liquid, since, by increasing the pressure, the high viscosity which this material had at a state of rest was reduced approximately to the low viscosity of ,petroleum. The sodium content caused tote A-Type fuel to react with Salbei by ignition. 'o water could contact fuel, however. f. Production of a dynamic measuring instrument for ignition delays and experiments with the unit. No standard measuring instruments for ignition delays could be used, since Salbei and A-Type fuel could not be mixed like C-Stoff and T-Stoff, and especially becausecktle`thixotropy of a-Type fuel. Therefore, a so-called dynamic ignition delay meter was built. The unit included two pressure containers of about 10-liter capacity into which the two components were filled. A constant pressure for these containers, about 10 atmospheres, was effected by Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 CuNFIDENTIAL~ nitrogen. Lifter the valves were opened, each fuel escaped tr:rough a nozzle and ignited when they met in the air. ,he angular position of the two nozzles to each other could be ad,usted.. Salbei was fed first, then the valve of the .,i-Type fuel was opened. The increase of pressure in the .a-Type fuel line was measured by a V2A diaphragm and an iieduction coil. The ignition point was measured by a photoelectric cell. The figures were evaluated similarly to tLose obtained by a standard ignition delay meter. The unit ;operated perfectly and was checked by a commission of the Ministry of Aviation which seemed to be very, impressed. It was unknown whether the Soviets continued experiments in this field or not. g. Production of a fuel from th:ixotrope petroleum with xantho;enate admixtures which reacted automatically to T-Stoff. Sinn.ltaneously, the Type A fuel, a dual with an automatic reaction to T-Stoff was m"O from petroleum. Sodium or MAO& potassium xanthoge Were pri according to the usual system.

This plan included the following details: (1) The production of magnesium borid (sic) to obtain boranes according to the Stock method. (2) The production of boro bromide to obtain boranes by silent electric discharge according to the Schlesinger system. The production of boranes of boro bromide by catalytic h,rdraticn.

During these experiments a conversion of boro bromide was achieved with lithium or potassium hydride. Ilowever, unlike the results of American experiments published at a later date, potassium boron hydrides were obtained iN:stead of borane. No further evaluations of these experiments were made, since the work of the Department of Chemistry cane to an end in Lay 1950. The planned work order of the i.:istry w_:,s cancelled because of the expected repatriation of the Jersian experts. :Miscellaneous Activities. Development work for the testing of powder ingredients for tetra fire extinguishers. Dipl I.1 Boris von Schlippe's department developed a fire extinguisher for aircraft. Tetra (sic' was pressed to the .fire by a burning powder charge. Dr Daniel (fnu) and Soviet experts developed this cylindrical powder charge of gelatinized nitro cellulose. A black powder train attached to the end of the charge was ignited electrically by means of a resistance coil. The weight of the powder charge was about 500 grams. Powder charge and tetra were separated by a cardboard diaphragm impregnated with a qglycerin/glue mixture functioning as packing material. After the ignition had started, the diaphragm was torn by t:.e explosion pressure. Tested in regard to their Ali"fusion resistance against tetra, these diaphragmoproved to be iualified. The combustion residues, however, settled in the tetra lines of the extinguisher and !light have caused corrosion. Na further information was obtained. 2 3 of potentiometers. Hard gold platinr- Dr Wlabde's department produced potentiometers for measuring purposes. Since the resistance of the contacts was effected by the slight corrosion at the soldered parts, the points of contact were gold plated. paraffin was put over tae potentiometer leaving out the contact areas which vre.re then gold plated by alvanization. During the same process, a chromium )latinE ;hard gold plating) was effected bj inducing short impulses of higher voltage at certain intervals. This ty,e of surface rotection was satisfactory. The potentiometers were used to indicate changes of the mechanical characteristics. Tests. Darin 1.94h and 1949, flight tests were conducted with the ri;LLer model of the DFS-346 at iJO airfield. Dip] Ing V Mans Motsch who twice piloted the plane was afterwards no longer allowed to fly because he wore nlasses. In early or _nid 1950, powered flight tests were made at Lukovice airfield CQNFIDENTIAI Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 which was still under construction at that time.

Improvised e juip,::ent for the powered flight tests including semi- under;ourd tanks and containers,Agge built by Horst , .niestaedt . No special e:luipment for the take off of rocket powered aircraft was available. The DFS-346 was suspended from the left wing of a Tu-4. No information was obtained on the type of suspension and the release of the parasite. The flight tests ended on 12 September 1950 when the model was destroyed in a crash. Unless gliding tests with s~;.aller models were planned, it seems improbable that the flight testes with DFS-34o were continued. .pct ivities at IKB II. 10. The activities of the Department of Chemistry did not permit any conclusions as to the development of a new type of rocket power unit at OKB II. No information was obtained on the existence of the DFS-468. It was pointed out that no powered test flights were made after 12 September 1950. At Podberezjne, 0EB II was often referred to as "Utopia" because only theoretical work was done there. During the period from 1947 to 1950, Ing Koessing (fnu) repeatedly complained about the slow progress in the development of the DFS-346. Is was assumed that these activities were slowed down by the Soviets wlbo were working on a parallel development. One night, Roessing caught Beretsn*ak (fnu), his Soviet deputy, copying the construction drawings. He concluded that this was done continuously. Burmeister believed that various projects were theoretically developed at 0KB II to be forwarded to the Air Force Ministry where they were checked or possibly evaluated. No information was obtained on the construction of any new type of aircraft. Gliding tests were coi,iiucted with various small aircraft models including a delta wing plane. No details were remembered. Designing of a Li,,-,ht Low-Attack Aircraft. I1. During 194B and 1949, Dr Burmeister and Dipl Ing Boris von 3chiippe worked on fuels with a lower boiling point to be used for the Sc':.aidt type pulse jet. They also tried to reduce t:ie boiling point of the fuels already available. 3cn' i pe was working si-nultaneously on the improvement of the Sch:iidt type pulse jet engine. No details were obtained. In about the Sumer of 1950, von 3chlippe stated that an aircraft powered by improved version of pulse jet units icas being built at experimental Plant No 1. In the restricted area of the Plant to which the German experts had .no:-ccess, Burmeister observed, that a light low-attack aircraft powered by two Schmidt type pulse jet engines was being built. The aircraft were usually covered with tarpaulins before being shilped away at night. 3 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 Approved For Release 2008/07/18: CIA-RDP80-0081 OA006100770001-2 CONFIDENTIA 12. Two of these aircraft were seen without a cover at a distance of about 30 meters. From the contours, it was determined that these two aircraft were definitely of the same type as the ones covered with tarpaulins which had been previously observed at a distance between 50 and 200 meters. These all-metal low-wing monoplanes had trapezoidal wings, a fuselage similar to that of Yak-type aircraft and andskid instead of landing gear. The two power units were mounted on the fuselage aft of the cabin in line with the wings. No other engine assemblies were observed. German experts stated that, between the Summer of 1950 and the Sa::mer of 1951, Experimental Plant No 1 in Podberez~e had produced a series of 300 to 500 such aircraft which, however, had not been developed there. It is assumed that these 300 to 500 aircraft were only parts of a series, and that the production of these aircraft was assigned to Experimental Plant No 1 to utilize its capacity. The Siebel and Junkers engineers who had been working in the assembly shop stated that, at the time this production started, the portion with the assembly line had not been entirely separated, and that the assembly line gave indications of the production of this type of aircraft. This aircraft had the follwwing advantages: It would land at improvised airfields, could quickly be loaded on two standard trucks, and its maintenance did not require well-trained personnel. The process by which the aircraft became airborne was unknown. No catapulting or similar equipment was observed. The aircraft was never seen in flight. Comment. This was confirmed by previous information. Comment. For a chart of activities at the Department of Chemistry at Experimental Plant No 1 in Podberez$e, see Annex 1. For a list of personnel, see Annex 3. Comment. For sketches of the twin-engine pulse jet aircraft, see Annex 2. During the last year of the war, the Germans had developed the EF-126 (cover designation Lili), a low-attack aircraft powered with one pulse jet unit carried over the fuselage. Three EF-126 models were shipped to Podberezbte. The project bras allegedly cancelled after a fatal accident. Except for the two power units, the arrangement of which is very probable, the reported aircraft has a striking resemblance to the EF-226 and is, therefore, probably a further development of the latter type. 74hen being reinterrogated, source stated that the aircraft observed had definitely been equipped with a cabin. This excluded the possibility that an experimental series of V-ls was concerned. According to previous information, such an experimental series of 25 V-ls had been built at Podberez*e between the Fall of 1949 and the S'Lmmer of 1950.
