X-15 FLIGHT REQUEST

Flight No.: 1-31-52 Scheduled Date : 7/16/62

Pilot: J. A. Walker

Subject of Test: Investigation of: 1. Notch filter at high dynamic pressure 2. Stability in ASAS mode 3. Aerodynamic drag.

Launch: Mud Lake on magnetic heading 177°, ASAS armed, SAS 6-10-8.

No. Time Alt V a q Event

1. 0 45 790 2 145 Launch, light engine - increase to 100% T, rotate to and maintain 6° a to q = 30°, maintain q = 30°.

2. 32 45 2200 6 1220 Maximum q.

3. 45 65 2800 2 1020 Pushover to 0 g.

4. 80 100 5400 0 440 Shut down - set SAS 6-6-0 (yar off) - perform dv pulse.

5. 142 105 5200 0 290 Pullup to 5° a. Perform da pulse.

6. 151 95 5100 5 480 Pullup to 10° a - perform da pulse.

7. 166 78 4800 10 840 Pullup to a » 15° - perform da pulse.

9. 205 85 3800 0 420 Extend speed brakes.

.

10. 236 65 3100 0 900 Retract speed brakes - perform pullup, pushover maneuver (a = 0 - 10 - 0).

11. 262 50 2400 0 1100 Perform pullup - pushover maneuver (a = 0 = 10 = 0), vector to high key.

12. 287 50 1600 0 480 Perform pullup, pushover maneuver (a = 0 - 10 - 0). Jettison (H2O2 off).

13. High key - check, ventral armed, pressurize tanks, push-to-test ball nose, perform pushover-pullup maneuver (a » 8, 0, 8).

Notes:

1. Duration of flight approximately 11 minutes.

2. q vernier will be set at 30°, a crosspointer will null at 6°.

3. Emergency lakes, Grapevine and Cuddeback

Ground Rules for NO Launch: l. Malfunction of any SAS channels

2. Malfunction of inertial platform attitudes

3. Malfunction of ball nose

4. Malfunction of radio, radar or microwave

Alternate situations after launch: 1. If engine light cannot be accomplished within 30 sec, jettison propellants and launch at Mud Lake.

2. If radio or radar fail proceed as planned .

3. For inadvertent engine shutdown:

Prior to 45 sec, return to Mud Lake

45 - 65 sec, Grapevine

65 - 70 sec, Cuddeback

Greater than 70 sec, Rogers

Two engine starts may be attempted

4. For yaw damper failure do not increase a above 15°.

5. For total pitch or roll damper do not increase a above 12°.

6. For ball nose failure, proceed through burnout, fly 1 "g" after burnout.

7. For delayed engine light pullup at 2-1/2g..
