X-15 FLIGHT REQUEST

Flight No.: 2-22-40 Scheduled Date : May 4, 1962

Pilot: Major Robert Rushworth

Subject of Test : Heat transfer, ASAS checkout and high angle of attack stability with partial speed brakes.

Airplane Configuration: Basic X-15

Launch: Hidden Hills on magnetic heading of 218°. ASAS "Armed."

No. Time Alt V a Event

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

2. 25 49 1800 10 Maintain 2g until q = 20°, maintain q = 20°.

3. 39 54 2500 4 Pushover to 0 g.

4. 70 73 4600 0 Reduce to 30% T, increase a to maintain 1 g (a » 3°).

5. 75 73 5000 3 Modulate speed brakes to maintain 5000 fps (dj » 25° deflection).

6. 103 73 5000 3 Burnout.

7. 115 73 4600 3 Roll to 60° right bank and increase a until 5g is attained or to dh = -25, perform dv step input.

8. 130 73 4000 - Roll to 0° bank angle, extend maximum speed brakes, decrease a to 5°.

9. 150 71 3000 - Disengage roll SAS, perform dv step input.

10. 160 70 2400 - Reengage SAS, perform dv step input.

11. Vector to high key for landing, jettison (H2O2 "OFF").

12. Check ventral armed, pressurize tanks.

13. Before APU shutdown, cycle controls, retract flaps, set stabilizer trim to zero, and push-to-test ball nose. Data off.

Notes: 1. Duration of flight approximately 9 min.

2. q vernier will be set at 20°, a crosspointer will null at 0°.

3. Emergency Lakes: Three Sisters and Cuddeback.

Ground Rules for "No Launch" in addition to Operation Manual: 1. Malfunction of any SAS channel.

2. Malfunction of inertial platform attitudes.

3. Malfunction of ball nose.

Alternate Situations After Launch: 1. If radar or radio fail; if inertial platform velocity is usable, proceed as planned, if inertial platform (velocity and altitude) is unusable reduce power at 60 seconds, set up constant conditions, proceed as planned.

2. If ball nose fails, proceed as planned.

3. If total pitch or roll SAS fails, proceed as planned, do not exceed 8°a.

4. For inadvertent engine shutdown; prior to 39 seconds, return to Hidden Hills, 39 to 50 seconds proceed to Three Sisters, 50 to 65 seconds proceed to Cuddeback, above 65 seconds proceed to Edwards - two engine restarts may be attempted in all cases.

9. If cabin pressure is lost proceed with alternate flight plan.
