X-15 FLIGHT REQUEST

Flight No.: 2-24-44 Scheduled Date : June 19, 1962

Pilot: John B. McKay

Subject of Test : Evaluation of heating rates at low angles of attack and low Mach number - evaluation of notch filter.

Airplane Configuration: Basic X-15

Launch: Hidden Hills on magnetic heading of 227°. SAS 8-8-8
 
 
No. Time Alt V a Event
           
1. 0 45 790 0 Launch, light engine at 75%T (maintain 75%T), rotate to 10° a.
           
2. 16 45 1300 10 Maintain 10° a until q = 20°.
           
3. 40 54 2000 5 Pushover to 0 g.
           
4. 60 60 3000 0 Increase a to 3°.
           
5. 74 61 3600 3 Reduce to minimum thrust.
           
6. 79 62 3800 3 Modulate speed brakes to maintain slow longitudinal acceleration (q » 1400).
           
7. 122 66 4200 3 Burnout - retract speed brakes and set SAS 8-10-8. Pull up at 3g until q = +20°.
           
8. 133 69 3800 8 Perform 45° right and left rolls.
           
9. 139 74 3500 8 Pushover to zero g.
           
10. 162 84 3100 0 Peak altitude, maintain 0g until q » -10°.
           
11. 175       Reset SAS to 8-6-8, vector to high key for landing, start 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 10 min.

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

3. Emergency Lakes: Silver 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 radio or radar 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 through burnout as planned, do not exceed 8° a after burnout.

4. For inadvertent engine shutdown; prior to 50 seconds, return to Hidden Hills, 50 to 60 seconds proceed to Silver, 60 to 74 seconds proceed to Cuddeback, above 74 seconds proceed to Edwards. Two engine starts may be attempted in all cases.
