X-15 FLIGHT REQUEST

Flight No.: 3-45-68 Scheduled Date: July 13, 1965

Pilot: Major R. Rushworth

Purpose: To obtain data for the following program:
 

1. Boundary Layer Noise - (Tom Lewis)


Instrumentation Engineer: Febo Bartoli

Launch: Delamar Lake #1 on a magnetic heading of 214°, MH-96 Adaptive, R.C. "OFF," BCS "OFF," heading vernier to "Standby," ventral off.

Launch point coordinates: 37° 22' N, 114° 35' W.
 
 
 No. Time  Alt  V   a q            Event
             
1. 0 45 790 2 145 Launch, light engine, increase to 100%T. Rotate at 10° a until q = 30°.
             
2. 27 48 1800 10 650 q = 30°, maintain q = 30°.
             
3. 36 55 2200 0 700 Pushover to zero "g."
             
4. 80 89 5500 0 800 Shutdown. Maintain a » 0.
             
5. 95 92 5350 0 670 Peak altitude. Adjust rate of descent to hold q constant at approximately 700 psf. (H dot » 145 psf, a » 4°).
             
6. 260 70 3200 4 700 Maintain H » 70,000 ft.
             
7. 295 70 2800 4 560 Cuddeback, vector to high key, speed brakes as required. Engine Master OFF. Make calibrate pulse.
             
8.           High Key - check flap and "Squat" circuit breakers in.
             
9.           Before APU shutdown, cycle flaps, set stabilizer trim to zero, data "Off."

Notes:

1. q vernier will be set at 30°, a cross-pointer null at 0°.

2. Emergency lakes: Hidden Hills and Cuddeback.

3. Flight duration: Approximately 11 minutes.

4. Flight plan based on 58,750lb thrust - Engine (#107).

Total burn time at 100% = 83 sec.

Launch Wt. = 33,750lb Burnout Wt. = 15,000lb.

Ground jettison check.
 

 Ground Rules For No Launch:
  1. Radio, radar or T.M. malfunction.

2. FCS malfunctions as indicated on Analyzer check list.

3. Malfunction of Ball Nose.

4. Malfunction of inertial platform.
 

 Alternate Situations After Launch:
  Failure   Action
       
1. Radio or Radar   Proceed as planned.
       
2. Total Pitch/Roll Damper   Turn Yaw OFF, maintain a > 0. Proceed as planned.
       
3. Total Yaw Damper

Fixed Gain in any axis

   Proceed as planned.
       
4. Attitude   Proceed as planned, except use 5° a in place of 30° q.
       
5. Ball Nose   Heading vernier to ·Y, proceed, use 2g for rotation.
       
6. Delayed engine light   Pushover to 0 "g" at H = 55,000 ft.

 

7. Inadvertent engine shutdown:

0 - 45 sec Delamar

45 - 68 sec Hidden Hills (2700 fps)

68 - 70 sec Cuddeback (4200 fps)

70 - Up sec Edwards (4600 fps)
