Flight No.: 1-30-51 Scheduled Date : June 27, 1962

Pilot: Joseph A. Walker

Subject of Test: High angle of attack stability.

Launch: Mud Lake on mag heading 177° - ASAS "Armed."

No. Time Alt V a Event

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

2. 23 48 1800 10 Maintain 2 g until q = 30°, maintain q = 30°

3. 37 60 2400 4 Pushover to 0 g.

4. 80 96 5500 0 Increase a until » 1.5 g is attained.

5. 84 99 6000 5 Burnout - pushover to 0 a roll to 80° left bank.

6. 104 107 5800 0 Pullup to 23° a (trim dh » -25) - perform da pulse at pilot's discretion.

7. 127 105 5000 21 Roll to 80° right bank.

8. 139 101 4500 20 Roll out on heading 177°, disengage roll SAS.

9. 157 100 4000 17 Reset SAS - pushover to 0 a for 5 sec. - pullup to 10° a.

.

10. 242 89 3000 10 Pushover to 0 a for 5 sec. pullup to 10° a.

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

12. Pressurize, check ventral armed.

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

Notes:

1. Duration of flight approximately 11 minutes.

2. q vernier will be set at 30°, a crosspointer will null at 23°.

3. Emergency lakes, Grapevine and Cuddeback

4. No in-flight jettison check

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 35 sec, return to Mud Lake

35 - 60 sec, Grapevine

60 - 65 sec, Cuddeback

Greater than 65 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 SAS failure to ASAS do not increase a above 20°.

7. For ball nose failure, proceed through burnout, fly q = 0° after burnout.

8. For delayed engine start add two seconds to pushover.

9. For attitude failure during powered portion: If horizon is not visible pushover to 0 g reduce to 75% T proceed to Edwards.
