M .P f Approved For Ise 2004/11/29: CIA-RDP71B0 OXC-9140-65 Cy-2o f 13 23 AUG 1965 SUBJECT : BLACK SHIELD Technical Meeting 12 August 1965. This report constitutes: Part I Part II Attachment I Attachment II Attachment III Attachment IV - General Aircraft Items - Propulsion Oriented Items; - Agenda - Decisions and Actions - Aircraft Summary - Engine Charts Part I - Aircraft General: 1. Attention is called to Attachment II, Decisions and Actions which summarize highlights of subject meeting. 2. With the exception of listing de-bug modification service bulletins applicable to BLACK SHIELD aircraft and presenting electrical and power transient mod status (charts to be available in D/TECH), the LAC presentation focused on management actions taken of Mr. Johnson's personal in-house investigation at Burbank. This investi- gation with its revealing findings was made possible by Mr. Johnson's reorientation into OXCART matters at the expense of other corporate responsibilities resulting from discussions and agreements reached between the initiator, Mr. Parangosky and Messrs Dan Haughton and Kelly Johnson. 3. Lockheed effort is focused on the _ primary BLACK SHIELD aircraft 126, 127, and 128 in order 0 Approved For Release 2004/11/29 : CIA-RDP71B00399R0006001 ,4H 25 25 Approved For ease 2004/11/29: CIA-RDP71B0039900600120017-3 0 that they be delivered to the detachment by 1 reliable weapon systems. Additional overtime effort is needed and scheduled on aircraft 126 because of improperly cured tank sealant in order to meet the 1 September delivery. Nos. 127 and 128 were reported as out of trouble in,the sealant area with a good chance of meeting the 1 September delivery. 4. A brief report bj 122 tests showed that the shape.

A chart supported presentation of engine related agenda items was given by Mr. Caleen and Mr. McDermott of Pratt & Whitney. Copies of the more significant charts are included with this report and copies of other engine charts are available in D/TECH. 2. Recent flight experience with "frosty" Hamilton- Standard fuel controls was reviewed. The fact that some trimming will be required for BLACK SHIELD was repeated. It is recommended that minimum trimming to near side of trim band only be used and that further test flights in aircraft 122 be accomplished using this technique while recording EGT and CIT with trace data. The effect on cruise SFC with variation of EGT over trim band was quoted as an improvement of 2.5% in. SFC as EGT increases from 755?C to 805?C. 3. A brief review of experience acquired with the derichment device on article 129 was reviewed. Results to date show a maximum temperature of 868?C for a period of less than 10 seconds. 4. "Chugging" and "die out" problems on the ground with engine 207 on the Scotch Mist exercise due to a defective compressor bleed pilot valve were reviewed. This problem has since been more thoroughly reviewed through phone calls and a meeting at Pratt & Whitney in Florida on 17 August. 5. The number 3 bearing compartment oil leakage problem was reviewed. One flight on article 129 was accomplished which reported good pressure data. It now appears that this data agrees with seal pressures calculated at FRDC. It is hoped that the testing now being accomplished on J engine 316 at FRDC might result in a simple field operable fix to the problem.. A change to the no. 3 compartment already instituted in later J engines may result in some tendency to reduce oil leakage through seals in this compartment during windmilling conditions. General expected levels of in-flight oil consumption were reviewed. The amount of oil which would be'consumed before I 25X SECRET 3 Approved For Release 2004/11/29 : CIA-RDP71B00399R000600120017-3 Approved For ease 2004/11/29 : CIA-RDP71B0039900600120017-3 warning lights flicker etc. is 3.2 gal. For flights of approximately three hours duration, oil consumption rates should not exceed one quart per hour. As shown on one of the attached charts for flights longer than three hours in duration, average hourly oil consumption rates are less than one quart per hour. 6. The problem of burning holes in burner cans, especially in the cross-over tube area between cans as experienced in engines 215 and 233 was reviewed. Engine no. 233 with 9 hours, 10 minutes of Mach 3 time was the first engine to approach the 10 hour limit of Mach 3 flight time between hot section inspections. This engine had some history of overtemperatures experienced in-flight but these were not considered at the time. It is hoped that J cans will realize some improvement. Five Y engines are now equipped with J cans, three sets are being installed and deliveries will continue until all Y engines are equipped with J cans in early 1966. It appears that this experience may "put a crimp in the effort" to increase Mach 3 hot section time beyond 10 hours, at least for Y cans. It is hoped that the J cans will provide some improvement. Engine 242 with J cans is now installed in the left side of article 129 and will soon be due for hot section inspection. 7. The gearbox bearing problem was reviewed and the modifications to the gearbox which will eliminate the gearbox vibration check on future overhaul and production engines were delineated. 8. The various engine wiring problems were discussed. These problems were also discussed in complete detail by D/TECH personnel during the visit to West Palm Beach on 17 August. A list of these wiring areas is as follows: a. Thermocouple harness nut retention. b. Tachometer cable connectors. c. Wiring and connectors to trimmer motor. d. General P&W experience with Bendix high temperature connectors, methods of attaching, etc. e. Supports for wiring and connectors so excessive lengths of unsupported wire do not exist. f. Jumper cable extension for right hand engine. 25 S 25X 4 Approved For Release 2004/11/29 : CIA-RDP71B00399R000600120017-3 Approved For ease 2004/11/29 : CIA-RDP71B0039900600120017-3 OXC-9140-65 9. One case of compressor first stage blade root cracking on a shimmed blade has been discovered to'date. This discovery was made at overhaul on a blade from engine 241. This engine had experienced 14 cycles to Mach 3. This blade had been reworked for adaptation of the shim and had therefore had .020" of material milled from the root,including the original root surface plating. The instrumentation program on engine 226 to investigate blade stresses and boundary layer airflow at the engine face was reviewed. This program was also reviewed in detail at the FRDC meeting on 17 August. 10. Priority engine flight test items were reviewed and a list of these are included on an attached chart. However, due to disagreements in priorities this list will be revised by P&W and a copy forwarded to Headquarters. 11. Other miscellaneous engine developments were discussed including the following: a. Engine relight experience with the Bill of Material 50 cc and the reduced 25 cc TEB shots. b. Mach 3 flight time by months. c. Ice ingestion tests on J58 engine. 12- It appears that the detachment especially Col. J may offer some resistance to use of the new AAR technique whereby one engine is left in A/B and throttle adjustments are made only on the other engine which operates below military power. It appears that there is some misunder- standing as to the exact procedure used by LAC pilots. The exact procedure being used by the LAC pilots and the weights of aircraft during recent successful refuelings with the new technique will be reviewed with the detachment. Due to the apparent success of the new technique it appears that every effort should be made to encourage the detachment to use it. 13. Engine associated action items are listed in the attached action item list. 0 SECRET 5 25X 25 Approved For Release 2004/11/29 : CIA-RDP71B00399R000600120017-3 I A.
