X-15 FLIGHT REQUEST

Flight No. 1-20-34 Scheduled Date of Flight: 12/08/60

Pilot: John B. McKay

Subject of Test: Evaluation of "hot nose," alternate airspeed sources; inertial velocity indication, and sidearm controller.

Airplane Configuration: Two XLR-11 engines; "hot nose," pilot's airspeed and altitude on alternate system, inertial velocity presentation to pilot.

Launch: M = 0.82, Hp = 45,000 feet, SAS 4-4-8, over Palmdale OMNI on magnetic heading of 030°.

No. Alt M M' a Event

1. 45 0.82 0.75 - Launch, light 8 chambers, initiate 8° a climb.

2. 44 1.2 1.05 3° Pushover to 1/2 g for roundout at 50K.

3. 50 1.3 1.15 6° Hold one g flight for » 5 sec, obtain calibrate, perform pushover-pullup with SAS 0-4-8 release. Reset SAS 4-4-8.

4. 50 1.7 1.50 12° Initiate 2 3/4g left turn. Perform 0-4-8 pitch pulse and 4-0-0 rudder pulse. Reset SAS 4-4-8.

5. 50 1.7 1.50 3° Roll out of turn on magnetic heading of 260°. After attaining 1g level flight perform pushover-pullup.

6. 50 2.0 1.75 2 1/2° Reduce to 5/8 thrust, perform full deflection constant heading sideslip with SAS 4-0-0, release. Reset SAS 4-4-8.

7. 50 2.0 1.75 12° Initiate left turn. After burnout hold 12° a while decelerating to M = 1.5.

8. 42 1.0 0.9 6° Roll out on magnetic heading of 110°, establish 260 knot glide. Evaluate sidearm controller.

9. - - - - Push-test "hot nose." Perform pushover-pullup - pullup near high key.

10. »20 »0.6 »0.56 2°-8° On downwind leg perform pushover-pullup.

11. Check ventral armed, pressurize tanks.

12. 300 knot landing approach, jettison ventral when clear, flaps and gear down. Intended touchdown is two - mile marker.

13. After touchdown, apply control for ground run evaluation.

14. Before APU shutdown, cycle controls, retract flaps and set stabilizer trim to zero. DATA OFF.

NOTES: 1. Duration of flight approximately 10 min.

2. Emergency lake -- Rogers.

ALTERNATE SITUATIONS:

1. Pitch SAS or roll-yaw SAS malfunction before launch will constitute an abort.

2. With three or less chambers operating, shutdown, jettison and land.

3. With four, five or six chambers operating, a constant turn should be maintained within 10 to 12 nautical miles of the base at or above 35K.

4. With 7 chambers operating, continue with original flight plan. Pushover during climb at 47,000 feet.
