The German labor groups comprised, in all., 16 engineers,, who had been deported to the USSR at the same time and Fleo released together on 16 May 1952. After fttno more German personnel remained in KB-3. Until June 1947, they worked essentially without Soviet co-workers except for auxiliary personnel. Sometime in June 1947, 50 Soviet engineers were attached to them. Each labor group in that period comp:r?ised., in, all, about 30 engineers, draftsmen) and helpers. 8. At first,the work was performed Jointly between the Soviet and German engineers. From 19489 on,the previously homogeneous work was gradually divided and in 1950 a complete separation of the group? into Germans and Soviets took place. It could no longer be observed-what the counterpart Soviet'groups were doing. German knowledge was progressively taken over by the Soviets, while the latter, for their part offered no insight into further development and were very mistrustful.

The future development of the ram-jet powered missile must be based upon the present situation. That may be described briefly. The principle of jet powered missiles may be presumed to be common knowle.dge~_ - 35. 36. Missiles in the A-series Large shell bodies with auxiliary thrust diffusor, large central combustion chamber, and stabilizing surfaces (flying without spinning), remote controlled on.ocassion, ' ? by means of a powder rocket., attain the necessary initial velocity of approximately Mach 1.5. In the first stage of.flight the combination shell-powder-rocket is guided along a firing track. This firing track sets the initial direction of the flight path. After the powder rocket or powder rocket composition has burned out, the-rocket is expelled and the ram-jet-power action begins. This -functions until the fuel is exhau$ted, at an altitude of approximately 25 kilometers, and then the missile travels. freely along a ballistic curve. Present ',projects in the A-series are as follows. Project Kilograms Kilometers A-1 50 50 Drafting project only. A-2 50 150 Drafting. project only. A-3 250 50 Drafting project only, A-4 250 150 Executed and attained. A-5 250 300 Drafting project only. A-6 =_1000 300 Drafting. project only. Of these designs the A-l+ is test-proven.

AAseries, A-5 and A-6Apromised a stepwise increase of range and payload up to 300 kilometers and 1000 kilograms. The powered missiles of the A-series are produced as simply and cheaply as possible. The primary part of the 4tsile (see E1losure 1, sketch.of A-h) is a standard thin walled tube. The central body is welded together from simple sheets. Fine mechanical treatment is reduced to a minimum. The-fuel required amounts to between six .percent and ten -,.percent of the missile by weight. The A-series missiles can carry a pay load up to 20 percent:,- of the total weight. A caliber between 30 and. 80 cm and a.missile length of between 2.50 meters and 10 meters seem most practicable. The firing from a ,rail., whibh is mounted as a.revolving unit on a truck or a full-track vehicle, allows a firing position at a, good.vantage point,.well. camouflaged, and independent of roads and railroads. Tiq take-off by powder rocket _ oduces great sources of error in.the fliVht path. The.'deviationthrough installation of a remote-control mechanism (radar-control) would rob this model of its most important advantage, its.low cost.of production. Future developments would have to be alor* the following lines:. a. Maintaining the over-land mobility ate. inconspicuousness of the firing unit. b.' Maintaining the simple,. cheap construction of the missile body. c. Careful examination of the possibilities of improving the deviation. The most serious disadvantage of the entire type is the necessity for powder take-off. The total Weight ..of the powder take-off rocket is approximately equal to the weight of the ram-jet missile. Emphasis in the further development must be put on increasing the range of velocity in .which the ram-Jet motor can operate,-thus increasing the initial velocity required by the ram-jet motor, and consequently permitting the mass and weight off' the powder take-off rocket to be lowered. For this purpose there arr~ arrangements which promise success. Careful study has shown the possibility of developing ,combinations of Schmidt-tubes and ram-jet engines in such a way that these combinations,operate as Scbmidt-tube in the lowet' velocities; the frequency of the individual combustions.of the Schmidt-tube increases as the velocity increases until about-Mach number 1.5, when the combustion goes over into the .continuous type of the -ram--jet engine. The initial velocity which would be effective in'such.a combination is estimated at about 80 meters per second, a.velocity which can be delivered by.a etanclard.catapult or.a very small powder rocket. The first experimental results on such combinations of Schmidt-tube and ram jet motors.might occur early in 1954. Mgssil+sa in the B,-S-rie In the case of missiles and launching units of the B-series the guiding principle was as,follows: The increase of initial velocities of prorjectile.s, in standard guns-reacheis a limit!, according'to caliber., in the neighborhood of 900-1000 meters per second. If higher velocities are to be obtained,,. there is a necessary disproportionate expenditure on the gun (gun weight, 4reight of powder charge, erosion within the rifle,, shortening of the life span), which make,;; the increase of projectile velocity beyond the limit stated ecorlomically impracticable or, indeed, impossible. If greater initial velocities and longer ranges are necessary, it is obvious that a basic velocity (600-900 meters per second) should be fixed for the gun itself, and then the projectile should be developed as a. ram-jet eagine,which increases it a.own velocityafter-leaving the gun. The fact that this mechanism h4,4-become possible in both principle and in practice by.means of the yet-to-be-discussed C and E-kseries is shown by the following.

Range-150 kilometers. Diameter of bore-57 cm. Length of the launching tube-36 meters (capable of being dismounted into six equal sections,: each six riteter5 lor7,g). Launching tube attached to launching base plate without recoil mechanism. Initial. velocity-800 meters per second. Highest gas..pressure-500 kilograms/cm?. Weight of launching tube-30 tons. Weight of base plate -8 tons. Such a.missile (to be designated B-3 in the development series) might combine optimal mobility with good range,: low deflections and the Lbweat.'u- production cost. The use of a propellant other than chemical explosives is easily possib e. For the explosive, whatever type it might be, :.space of 0.16 to 0.2 m is provided. C-Series projectiles which are fired from standard guns. During 25X1 the firing process with the guna cartridge-case base covers the hollow chamber running through the entire projectile, in which the propelling forces.of the ram-jet are later released. This cartridge-case base falls off after the projectile has left the muzzle of the gun. The projectile is !Stabilized through rifling. The ram--jet begins to operate immediately after the projectile leaves the gun muzzle. The initial velocity is .set for more than 900 meters per second. At this velocity and with suitable fuels,self-ignition of the fuel is guaranteed. The fuel is driven partly by rotation and partly.by.means of special aids (pressure gas,. burning powder cartridge) through jets into the combustion chamber. The most-important results of the development projects were: a. The design of the diffuser at the nose of the missile in such a way that the projectile operates under almost optimal conditions in a.rather great velocity interval (Mach . 2.6 to 6). b. Design of the projectile so simple as to place the cost of pro- duction no higher essentially than that of the standard projectile for the same gun. This goal was.reached.to the extent that the production-material costs for missiles of the C-series were only 2.0 to 2.2 times as high as the costs for a regular projectile. c. Development of a simple control devices for limiting the dispersion of range on a horizontal target: 1) The introduction of a simple acceleration regulator (in testing stage). 2) The introduction of a means of limiting the combustion period (not yet being tested).

Exhaustive investigations have shown that projectiles of the,C-series.are not to be built under.21 cm caliber. Twenty- one cent.meters is the limit below. which.an..explosive pay load can not be borne. The larger the caliber, the larger the borne explosive pay load can be in proportion to the normal fuel load. In 38-cm caliber missiles already 65 percent of the explosive pay load of the standard projectile can be carried. The initial velocity cannot be reduced essentially below.900 meters per second. The maximum velocity is about 1900 meters per second. The heating up at this velocity causes serious difficulties. e. Ranges up to 360 kilometers can be realized. Within these limitations the powered missile of the C-series is, for all calibers above 28 cm,,an effective and promising improvement on existing missile types. These missiles can be used at very low cost. The gun tube is not subject to the stresses, occasioned by ordinary projectiles. The gas pressure is always around two-thirds of normal gas pressure. Only through the use of the cheap powered missile of the C-series can ranges up to 350 kilometers be reached with any gun, from 28 cm caliber on up. In the D-series, missiles. are planned which no longer fly on a',ballistic curve but by remote control in horizontal flight at great altitudes over maximum distances. The take-off here)tootaffords difficulties which have not yet been ironed out. A _take-off by. means of powder rocket requires enormous velocity for such a missile. The total take-off unit of powder rockets would weigh two to three times as much As the missile itself. Another launching method seems more promising.. A heavy mother aircraft tows the missile, to 12,000 -15,000 meters' altitude. The missile is then released in a dive and brought up to Mach numbeii l.5 by meansi of a.small powder rocket. Mach 4 has been determined as the most favorable operations. Mach number for missiles of the D-series. From Mach.l.5 up to Mach 4 the missile propels, itself by using its own fuel supply, which likewise produces the energy necessary to lift the missile tote moat favorable operational altitude (24.kilometers). A .ton ton miss ile flying 1200 meters,per second at.24 kilometers'altitude uses i.5 kilograms of fuel per second. With its fuel supply of 6000 kilograms it can fly 4000 seconds and can cover a,powered-flight distance of 4800 kilometers . It can cover an additional distance of about ?+00 kilometers in glide flight; thus,distances of over 5000 kilometers can be attained with such missiles. Operational velocities greater than.Mach 4 appear to be unfavorable for the fhlowing reasons; a. The efficiency of the ram-jet engine does not increase-essentially with increased Mach number. b. The fuel requirement for each kilometer of distance increases. c. The heating-sup. of the entire missile at higher Mach numbers would require the use of expensive special alloys in this construction. A. The thermal stress of the combustion chamber cannot be endured. over extended.flight periods by alloys known at this time. In the case of the above-mentioned example, all parts of the missile are exposed to temperatures of about 620?C. The..combustion temperature will amount to about 1100?C. k cperi;nenta1 E-Series In the E-series (E-1 to E..7 produced and tested) were. powered missiles which were shot from guns of 10.5 cm (E-1), 12.2.cm.(E-2), and 15 cm.

This E-series produced cheaply and con- clusively a large fund of knowledge. A missile of the E-series cost about 200 to 250 RM and produced data for the construction of larger missiles. 45 F-1 and F-2 in the F-series are antiaircraft missiles which have been designed and constructed in detail (19)+5). Present-day flight velocities and altitudes make it inadvisable to pursue these types further. Summary 46.. According to the preceding discussion the following projects offer promise of success: a. A reconstruction of A-4 and, on the basis of the knowledge to be gained through this reconstruction, the continued development of missiles and powder rockets for distances of '100 to 350 kilometers and pay loads of 250 to 1000 kilograms. The chief emphasis in the development program will be'-placed on the effort to reduce the initial velocity of the ram-jet engine through combination with the Schmidt- tube. b. Construction of the B-3. A carefully prepared drawing model of B-3 can be produced within four months after assignment of contract. Experiences with a B-3 unit could help in producing data for the further development of types in this series, which could be developed as long-range artillery and mounted on ships for use in naval warfare. c. A reconstruction of the C-3 or similar missiles of the C-series for guns of 28 cm caliber and up. Most promising utilization of this type is on shipboard for naval warfare. A carefully worked out con- struction of this type can be prepared within six months after assign- ment of contract. d. Missiles of the D-series for maximum distances of 5000.,6000 kilometers. Pay loads of 1000 kilograms can be established as standard'. The scarcely promising powder-rocket launching of the missiles of the D-series is not recommended. A missile of the D-series can be designed and constructed when the data for a launching from a heavy mother air- craft has been clarified. Than the construction of a D-series missile will meet with no significant difficulties as far as the problem of propulsion is concerned. The question remains unanswered, whether an effective control by means of radio control units can be realized over such great distances, The construction and careful completion of the driving mechanism of the D-missile might require four months. e. If the further development of ran-jet engines for high Mach numbers is seriously considered, the continuation of the experiments with the simple E-types promises good results. The most suitable caliber seems to be 15 em, The com- 25X1 pletion of a missile design for the E-series requires about three months.

Preparation for firing: The missile, less diffusor spike (1) nose (5), striker (6), detonator (8), and cartridge-case base (34, 435, is taken from the packing case and installed in a rack (Laboriervorrichtu ) in such a way that it can easily be rotated aroun its gravitational axis,so that now the nose and then the tail of the missile can point vertically upward. The nose of the missile-is swu upward. The igniting charge (9,10) is inserted the detonator is threaded on (8), the striker ) and the nose (55 are inserted. (The very sensitive:nose piece and diffusor spike are protected in transport by cotton-wadding packing The tail of the missile is.'swung upward. In a filling can the flame-thrower fuel and carbon disulphide are weighed off and mi=d. The mixture is then poured into the fuel container (31); the packing ring (42) is carefully threaded in. This causes a drop of excess fuel to run out at the opening (40). Then the venting screw (40) is inserted and screwed tight. Finally the cartridge-case base (4+3, 44) is inserted. This must sit loosely and slide'easily. If a cartridge-case base sticks, it should be discarded, The seat and sliding :surfaces of the cartridge- case base are to be cautiously cleaned and slightly greased before being inserted. After the cartridge-case base has been inserted, liquid paraffin (1.5 kilograms) is poured in at the funnel of the jet (3). The paraffin, when cooled, holds the cartridge-case base firmly in position and is pressed, at firing, by the powder gas pressure into the fine crevice between the missile and the cartridge-case base, thus preventing the cartridge-case base from seizing or sticking or being blocked by the residue of combustion, The so-prepared missile is placed into the gun- barrel combustion chamber in the usual way, during which operation special care is taken to see that the sensitive diffusor spike is neither bent nor otherwise damaged nor the missile nose damaged.

Initial velocity: 1225 m/s (Mach .3.6). In launching,rotation and initial velocity are imparted to the missile in the extended portion of the gun barrel by the pressure of the powder gases. The cartridge-case base prevents powder gases from entering the combustion chamber of the missile between the casing and fuel container (23). The rotation flaps (15) cause the liquid fuel to rotate along with the missile before the latter has left the gun barrel. That portion of rotating liquid between the rotation flaps is driven outward by centrifugal force and leaves the area between the rotation flaps at the outer wall of the fuel container. There is still no rotational flow of liquid along the axis. After, a few turns of the missile the -.. !. entire contents of the fuel container are driven by the rotation flu 8 and are involved in the rotation of the missile. The propellant (32.) is likewise ignited within the gun barrel. Under the effect of the discharge acceleration of 6000 g (sic) the firing pin (36), as a result of its inertia, breaks the shear pin (37) and strikes against the ignition cap (30). Through the pointed flame of the exploding ignition cap (30) the primer charge (35) is ignited. After a very small pause,the primer charge (35) conveys the flash on to the powerful ignition charge (33), which in turn ignites the (carefully cleaned and roughened) surface of the propellant (32). The rising powder gas pressure in the chamber of the fuse cap (38) bursts and opens the weakened central part of the fuse cap in such a way as to permit the powder gases to enter the fuel container (23) and exert a pressure on the fuel. The cylindrical propellant (32) is wrapped by a chemical-mechanical procesa, with a propellant cover (alternating layers of asphalt and elastic crepe paper applied under pressure) in such a way as to allow only the frontal. area to burn A safety pressure valve, not drawn in sketch,,,allows the escape of excess gases so that the powder gas pressure will not rise over a desired maximal level. c. After firing (launching) After the discharge, air pressure has-been built up in the com+ bustion space between the outer shell (2) and the fuel container. This pressure ejects the cartridge-case base from the missile. Through the compressed hot air the collodion layer (45) is likewise destroyed and the spray nozzles (24) are cleared. The fuel, under a powder-gas pressure of approximately 180 atmospheres and under an additional centrifugal force of about 38'atmospheres in the pert heral area of the fuel container, is led through,the fuel lines (16) to the accelera- tion regulator (19, 20, 21, 22, 46, 47, 48, 49, 50). The acceleration- regulating weight (20),with interval rings (47, 48),slides freely over the light elastic split tube (21) made of plastic. The acceleration- regulating weight is held between two leaf springs (19). If the driving thrust makes the longitudinal acceleration too high, the acceleration- regulating weight, under the influence of the acceleration, slides to the rear, covering over the passage slit and throttling the fuel supply. If the acceleration is too low, the acceleration-regulating weight opens up'.a greater portion of the slit in the split tube and the fuel supply increases. Through the fuel lines (17) the fuel is led out of the split tube into a circular distributor space before the spray nozzles. A'1Iorough preparation; of the fuel-air mixture is provided by the 14;8O ' spray. nozzles (24),whose inside diameter is 0.25 mm. ..The, spray nozzles are inserted in deep cavities, the ignition cavities,.in such a way that the ignition cavity supports the ignition process as a type of Aflame holder". At the same time the vortex area at the edge of separation of flow at the end of the explosive container (il) has a stabilizing effect on the formation of the flame.

A spontaneous combustion process is introduced especially by the admixtuve of carbon disulphide. As a con- sequence of the multiplicity of injection points, of high injection pressure and the resultant good atomization of'the fuel droplets, of the high temperature (760 degrees c,enti.grade), and of the high pressure (68 kg/mn2) of the combustion air, the combustion is quite complete- in spite of the high air velocity in the combustion chamber (70 m/si and in spite of the very short combustion duration period (2.5 thousandths of a second). At the end of 'combustion the gases in the missile have reached a temperature of 1670 degrees centigrade. The combustion. gases leave the nozzles at 1700 m/s and develop a thrust of 2280 kilograms. After 20 seconds the combustion is completed; the missile has reached its maximum velocity of 1880 m/s at an altitude of 24+ kilometers. The protection of 'the interior walls of the combustion chamber against high temperatures is done in the following manner: The wall of "the fuel container is greatly cooled by the fuel, which adheres to the wall as a result of centrifugal forces. The flame is directed by the manner-of injection in such a way that it does not touch the outer shell(O un- til it reaches the end of the combustion chamber. The air streaming past outside removes heat from the outer shell. The great mass of the nozzle (3) is able to absorb heat during the short burning period. Nevertheless, there were instances of 'bore erosions observed in the nozzle (3); these erosions were of no significance in the function'-.'of the missile, however. The most difficult part of the cooling was the effective cooling of the posterior flanges (Stege) (26). This was done by means of borings connected with the fuel container'and filled with circulating fuel. All parts exposed to the flame are provided with ceramic insulation. Rotation gain: During flight the gases drive,the diagonal posterior flanges in such a way as to increase rotation so that even at terminal velocity the rotation values necessary for a stable and continuous trajectory have been maintained. Missile at impact: The missile of this type is provided with a stir-- sensitive impact detonator. The missile nose, fixed at three places, and the rigidly bound striker give enough impetus, even when the missile lands at an angle slightly less than vertical, to the detonator to ex- plode the charge above ground (impact velocity at about 480 m/s) SECRET/CONTROL, US'OFFICIALS ONLY Sanitized Copy Approved for Release 2010/01/19: CIA-RDP80-0081OA003900600005-8 Sanitized Copy Approved for Release 2010/01/19: CIA-RDP80-0081OA003900600005-8 Putilovo 30 June 1945 16 June 1952 Project 1947 1948 1949 // 1950 1951 1952 A-4 Theoretical and construction work on A-4 ( Beginning of 1950: A-4 and C-..running parallel construction finished Theoretical and construction work on A-4 To end of 1950: Improvements and C-3 running parallel ) in construction, experimental' firings (possibly of C-3 and I C-3 End of 1949: C-3 A-4) `A EDnstruCtiOII I completed Development in the Experimental firings I E-5 test nu.ssile Improvements in I construction Tunnel built and used Calculations and studies I ! - 10 x 10 an 1 in experiments; Mach 8 wind tunnel 2.5 z 25 cm 'Calculations and Corking( Building of structures Wird tunnel (drawings until.
