Flight: 3-43-66
Date: June 16, 1965
Pilot: Capt. Joe Engle
I. PRELAUNCH AND LAUNCH PHASE
2. X-15 radios - Had a good deal of static or hash in the background and the volume was a little bit less than normal, I'd say about 3, or 4 by 4. This continued on out until just about the launch point, then they seemed to clear up fairly good. During the radio check when I was on X-15 radios only, the reception was a lot better than through the B-52 radios.
3. APUs - The start up was abnormal in that the No. 2 APU dropped off the line. I didn't have an indication in the cockpit that it was off until I tried to reset the generators. The No. 2 generator wouldn't reset and about that time No. 2 pressure started to drop off just slightly, just enough to notice. So the No. 2 APU was restarted again, generators reset, and then we went into the procedure of shutting down and restarting the No. 1.
4. Damper system - Worked real good.
5. Flow direction sensor - The ball nose looked normal during the prelaunch phase.
6. Launch space positioning - Was real good.
7. Launch transients (q, f, y) - There were no launch transients that were any worse than normal.
8. Engine start - Was normal.
9. Unforeseen incidents - There were no other unforeseen
incidents other than those mentioned during the prelaunch phase. I guess
radar dropped out but that was a problem here on the ground.
2. q control - Was normal, easy.
3. a control - Was no problem. The "g" during rotation built up to almost 2 1/2, so I let a droop to about 10 degrees intentionally, during the latter part of the rotation.
4. The altitude profile versus simulator - Was real close to what we'd seen on the simulator.
5. Unforeseen incidents - No unforeseen incidents during the burn portion.
2. Stability in ballistic flight (RAS ON) - Was very easy to control. I'd rate:
q 2 , f 2 , y 3 .
2a. Controllability in ballistic flight (RAS ON) -
q 2 , f 2 , y 3 .
3. Controllability during initial and terminal reentry - During the initial phase we got this pitch oscillation and I'm still not sure just what started it off. I thought probably it would damp out, so I didn't make any inputs for, I guess, a couple of cycles there, about a cycle and 1/2, then started putting in some inputs with the control stick, and by then the q was building up and I think we'd be getting into the terminal phase by then so, during the initial phase:
Initial q 4 , f 2 , y 3 .
Terminal q 2 1/2 , f 1 1/2 , y 1 1/2 .
4. Glide energy management versus simulation - Was very good. We started out with a little bit higher q than I had come out with on the simulator, after the reentry, so I leveled out and got the q back down to about 700, I believe, and from there on, it was real good.
5. Approach and landing - Were normal with the exception of the airspeed indicator which apparently is indicating about 15 - 20 knots slow all the way down to at least 240 knots, I believe that's where we got the airspeed check, on the flare.
6. Unforeseen incidents - No particular unforeseen
incidents other than the F-4 airplane on the runway. I had intended to
touch down a little short to try and get slowed down quite a bit before
getting to the F-4, but it just seemed to keep going. I didn't want to
fight the airplane on the ground. I think probably this airspeed indicator
is giving us about another 15 - 20 knots than what we're indicating. Touched
down just about at the smoke bomb, as a result, and as soon as I touched
down I put forward stick in, and then started all the way over with right
aileron, to start the airplane veering to the right, away from the F-4,
and it seemed to work real good.
q 4 , f 2 , y 3 .
