Turbulent flow over vehicles at angle of attack

20th Aerospace Sciences Meeting, 1982
I recent years the parabolized Navier-Stokes (PNS) equations have frequently been used to calculate steady viscous supersonic flows about a variety of three-dimensional geometries at angle of attack. Some results have also been obtained for turbulent flows where an algebraic turbulent eddy-viscosity model has been incorporated in the PNS equations ...

Inlets for high angles of attack

Journal of Aircraft, 1976
Different inlet designs for high angle of attack STOL and VTOL applications were tested in a subsonic wind tunnel. Three removable entry lips having contraction ratios of 1.30, 1.34 and 1.38 were tested with a single diffuser. The internal contour of each entry lip was an ellipse with a major to minor axis of 2.0.

Angle of Attack as an Aid to Flying

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">Application of the early ideas of Wilbur and Orville Wright, in regards to angle of incidence, has provided the Navy with an effective method of controlling airplane approach and landing speeds. The current Navy angle-of-attack systems have commercial applications for use in landing, clear air turbulence, stall ...

Viscous Flow over Spinning Cones at Angle of Attack

AIAA Journal, 1973
A numerical finite-difference method is developed for evaluating the Magnus coefficients on spinning cones in laminar flow. The merged layer, the strong interaction region, and the downstream boundary layer are all considered. The numerical method is a predictor-corrector scheme developed for three-dimensional flows with or without crossflow diffusion.

Prediction of Separation Angles Induced by Sharp Fins with Attack Angle

AIAA Journal, 2001
Introduction G LANCING shock-wave/turbulent-boundarylayer interaction, in which an oblique shock wave glances across a boundary layer along an adjacent wall (Fig. 1), constitutes one of the most important phenomena of three-dimensional interference.
