Flight No.: 3-9-17 Scheduled Date: August 10, 1962
Pilot: Joseph A. Walker
Subject of test: Constant q entry and stability at minimum yaw gain.
Launch: Delamar
Lake on a magnetic heading of 205° with MH-96 FCS on Adaptive Damper,
FCS Reaction Controls "AUTO" and both BCS "ON."
No. | Time | Alt | V | a | q | Event |
1. | 0 | 45 | 790 | 1.5 | 145 | Launch - light engine, advance to 100%T - use pitch rate trim for rotation to a » 10° (dh » -8) - Do not exceed 3 g. Trim f if necessary. |
2. | 29 | 47 | 1850 | 10 | 700 | Maintain pitch rate until q = 32°, maintain q = 32°. |
3. | 70 | 110 | 4300 | 4 | 300 | Pushover to 0 "g" (use dh trim to +3°). |
4. | 83 | 140 | 5800 | 0 | 160 | Burnout. |
5. | 120 | 200 | 5400 | 0 | 16 | Roll to 30° right bank, maintain for approximately 30 seconds. |
6. | 161 | 220 | 5200 | 0 | 9 | Peak altitude - engage q Hold (at q = 0°), zero side stick trim knob and use pitch vernier trim wheel to maintain q = 0° - extend speed brakes. amax during entry approximately 20°. |
7. | 239 | 125 | 5500 | 20 | 180 | At 1 "g" reduce to fixed gain in yaw, RC "OFF," perform dv pulse (no da inputs). |
8. | After entry completed, vector to high key, depress CSS button - jettison (H2O2 "OFF"). | |||||
9. | High Key. Check ventral armed and pressurize tanks. Push to test ball nose. | |||||
10. | After touchdown, disengage MH-96 FCS. | |||||
11. | Before APU shutdown, cycle controls, retract flaps, trim stabilizer zero, data off. |
Notes:
2. Duration of flight approximately 10 minutes.
3. Emergency lakes: Hidden Hills and Cuddeback.
2. Stable platform malfunction in attitudes.
3. Ball nose malfunction.
4. Radio or radar failure.
2. For delayed engine light, proceed as planned, maintain less than 3g during rotation.
3. For radio, radar or microwave failure, proceed as planned.
4. For FCS failure to fixed gain damper in yaw, proceed as planned, attempt to reengage damper and turn FCS reaction controls to "ON."
5. For total yaw damper failure, proceed but do not increase a above 15°. Attempt to reengage damper. Make entry with speed brakes open. Use b-dot if necessary.
6. For FCS failure to fixed gain in pitch or roll, push over to zero "g" at 50 sec. Use speed brakes open for entry at a between 13° and 20°.
7. For total FCS failure in pitch or roll, push over to zero g at 40 sec., extend speed brakes, proceed to Edwards.
8. For ball nose or attitude failure, do not use Hold modes, push over at 50 sec., reduce throttle and continue to Edwards. Enter with dh » 20°. Extend speed brakes.
8. For inadvertent engine shutdown prior to:
48 - 65 sec Hidden Hills.
65 - 70 sec Cuddeback.
70 - Up sec Edwards.
