WebIt is not angle of attack that the rule refers to. It is Q-alpha which is the dynamic pressure times the angle of attack. The shuttle had pre-calculated Q-alpha and Q-beta structural limits; apparently Apollo did too, and this rule applied when the instantaneous value of Q-alpha reached or exceeded 100% of the pre-calculated structural limit. Edit: Webangle of attack (∆α = 10°) was insufficient to obtain a more precise location of the pitching moment reversal. It must be noted that after the first Shuttle flight, the real-gas influence on

Space shuttle angle of attack

WebThe guidance program is a precalculated lookup table of pitch vs time. Control is done with engine gimballing and/or aerodynamic control surfaces. The pitch program maintains a zero angle of attack (the definition of a gravity turn) until the vacuum of space is reached, thus minimizing lateral aerodynamic loads on the vehicle. Webshort, was to fly in the now standard heads-down attitude: i.e., at negative angle of attack. Thus, the scheme was to fly the wings at near zero panel load and to deflect the elevons …

WebBecause the Orbiter wings developed lift at zero angle of attack, the high dynamic pressure portion of ascent had to be flown at a negative angle of attack, close to the zero lift angle. This could have been done heads-up or down, but the early crew members expressed a preference for having a horizon view. This led to the heads-down attitude.
