Journal of the Korean Society for Aeronautical & Space Sciences, Vol. 30, No. 1. Nonlinear trajectory control using drag-to-altitude transformation for entry guidance. WebSpace Shuttle true airspeed, angle of attack, and sideslip angle are currently derived from inertial guidance information. A new method is proposed which offers a potential improvement in Shuttle safety during entry. Angle of attack, sideslip angle and true airspeed could be measured directly at heights from 120 km down to 20 km by Doppler sensing …

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. 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. federal management company inc https://aaph-locations.com
