X-15 FLIGHT REQUEST

Flight No.: 1-29-50 Scheduled Date : 6/7/62

Pilot: J. A. Walker

Subject of Test: Local flow at high angles of attack.

Airplane Configuration: Basic X-15.

Launch: Hidden Hills Lake on magnetic heading 180°.

No. Time Alt V a Event

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

2. 25 48 1800 10 Maintain 2 g until q = 30°, maintain q = 30°

3. 37 60 2300 5 Pushover to 0 "g."

4. 80 97 5600 0 Shut down engine - roll to 60° right bank, increase to 10° a when q = 0°.

5. 107 100 5300 10 Pullup & pushover to a = 15°, 20°, 15°, 10° with approx. 3 sec. hesitation at each a. Maintain q» 0°.

6. 152 87 4200 10 Pullup and pushover to a = 15, 20, 15, 10° with approx. 3 sec hesitation at each a. Maintain q» 0°.

7. 180 75 3200 10 Pullup to 15° a - pushover to 10° a, extend brakes.

8. 205 68 2200 15 Vector to high key for landing, start jettison, H2O2 "OFF."

9. Check ventral armed, pressurize tanks.

.

10. Before APU shutdown, cycle controls, retract flaps, set stabilizer to zero, push-to-test ball nose - data OFF.

Notes:

1. Duration of flight approximately 10 minutes

2. Emergency lakes: Three Sisters

3. q vernier will be set at 30°, a crosspointer will null at 20°.

GROUND RULES FOR NO LAUNCH: 1. Malfunction of any SAS channel

2. Malfunction of inertial platform attitudes

3. Malfunction of ball nose.

ALTERNATE SITUATIONS AFTER LAUNCH: 1. If engine light cannot be accomplished within 30 seconds, jettison propellants and land at Hidden Hills.

2. For delayed engine light add 5 seconds to pushover time.

3. If radio or radar fail proceed as planned.

4. For inadvertent engine shutdown: prior to 45 sec., return to Hidden Hills; 45-60 sec. proceed to Three Sisters; 60 sec. and greater proceed to Edwards. Two engine starts may be attempted at any time.

5. For yaw or total pitch damper failure do not increase a above 15°.

6. For total roll damper failure - extend speed brakes, proceed to Edwards.

7. For ball nose failure, maintain 2g until q = 30°, pushover to zero g at 37 sec., shutdown engine at 5000 fps (74 sec.) proceed to Edwards.
