High Angle-of-Attack Pitching Moment Characteristics of Slender-Bodied Reusable Rocket

Effect of Amplitude and Mean Angle of Attack on the Unsteady Surface Pressure of a Pitching Airfoil

Details of pressure distributions, on a two dimensional airfoil oscillating in pitch through stall, in a 0.8 0.8 m low-speed wind tunnel are presented. Pitching occurred about the airfoils quarter-chord axis. Pitch rate, Reynolds number, and oscillation amplitudes were varied to determine the effects on pressure and lift distributions. It was found that mean angle of attack and pitching amplitu...

High Angle of Attack Aerodynamics

High angle of attack aerodynamics is inherently associated with: • separated flows, and thus nonlinear aerodynamics > one of the key aspects is the interaction of components, and in particular, vortex flows (vortex bursting is also an important effect) • heavily dependent on wind tunnel testing • connected with flight simulation to ensure good handling qualities > this means that large amounts ...

1 X - 33 Hypersonic Aerodynamic Characteristics

Lockheed Martin Skunk Works, under a cooperative agreement with NASA, will build and fly the X-33, a half-scale prototype of a rocket-based, single-stage-to-orbit (SSTO), reusable launch vehicle (RLV). A 0.007-scale model of the X-33 604B0002G configuration was tested in four hypersonic facilities at the NASA Langley Research Center to examine vehicle stability and control characteristics and t...
