X-15 FLIGHT REQUEST

Flight No.: 2-27-47 Scheduled Date : August 15, 1962

Pilot: Major R. Rushworth

Subject of Test : Heating rates at high Mach number and moderate angle of attack, ASAS check, aerodynamic drag and stability.

Launch: Hidden Hills Lake on magnetic heading 180°, ASAS "Armed," SAS 8-8-8

No. Time Alt V a q Event

1. 0 45 790 2 145 Launch, light engine, increase to 100%T, rotate until 2g is attained.

2. 19 46 1700 10 600 Maintain 2g until q = 20°.

3. 40 58 2600 34 850 Pushover to 0g.

4. 55 67 3500 0 1000 Roll to 80° right bank.

5. 61 70 3900 0 1100 Increase a slowly to 10°.

6. 68 71 4500 4 1200 Reduce to 40%T.

7. 75 75 4800 10 1250 Modulate speed brakes as required to maintain constant conditions.

8. 92 76 4900 10 1300 Burnout - extend speed brakes as required to vector towards Edwards.

9. 120 76 3800 10 800 Disengage yaw damper - perform dv pulse at pilot's discretion.

10. 130 76 3200 10 575 Reengage yaw damper.

11. 140 77 2800 10 475 Disengage yaw damper - perform dv pulse at pilot's discretion.

12. 150 80 2400 10 250 Reengage yaw damper - pushover to 0g.

13. 170 85 2000 0 150 Peak altitude - increase a to » 5°.

14. 240 56 1400 5 250 Retract speed brakes - perform pushover-pullup maneuver.

15. Vector to high key - jettison (H2O2 "OFF").

16. High key, check ventral armed, pressurize tanks at M = .8, push-to-test ball nose, perform pushover-pullup maneuver.

17. Before APU shutdown, cycle controls, retract flaps, set stabilizer trim to zero. Data off.

Notes: 1. Duration of flight approximately 9 min.

2. q vernier will be set at 20°, a crosspointer will null at 10°.

3. Emergency Lakes: Hidden Hills, Silver and Three Sisters.

Ground Rules for No Launch: 1. Malfunction of any SAS channel.

2. Malfunction of inertial system attitudes.

3. Malfunction of ball nose.

Alternate Situations After Launch: 1. If engine light cannot be accomplished within 30 sec., jettison propellants and land at Hidden Hills.

2. For delayed engine light, add 2 sec. to pushover time.

3. If radar or radio fail, proceed as planned.

4. For total pitch or roll damper failure, do not increase a above 8°.

5. For ball nose or attitude failure, vector to Edwards for landing.

6. For inadvertent engine shutdown:

0 - 35 sec Hidden Hills

35 - 54 sec Silver

54 - 65 sec Three Sisters

65 - Up sec Edwards
