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.

Prediction of Shock Angles Caused by Sharp Delta Wings with Attack Angle

AIAA Journal, 1998
Using a combined method, one can specify the trace of the shock generated by a swept sharp fin on the wall for various angles of attack α, sweep angles λ, half-apex angles e, and Mach numbers ...

Determination of Attack Angle and Tilt Angle of a Cutting Pick

Advanced Materials Research, 2013
Mechanical excavators play an important role in mining and construction. An excavation machine cuts rocks using its cutterhead which is normally composed of a large number of cutting picks. These picks are installed on a drum with certain attack angles, tilt angles and skew angles. These angles, especially attack and tilt angles, will affect the forces

High Angle of Attack Missile Aerodynamics

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1993
A major influence in the aerodynamics of missiles is the significant amount of separated flow encountered for most flight conditions. This flow may be of an ordered nature, forming vortices, or random, such as encountered in wing stall. At high angles of attack the vortices of the body leeside flow may become unpredictably asymmetric, even on ...

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.

Aerodynamics of finned missiles at high angle of attack

9th Aerospace Sciences Meeting, 1971
A theoretical and experimental investigation of the aerodynamics of finned missiles at high angle-of-attack is presented. The interaction of the body vortex wake region with the missile fins aiid the resulting effect on the forces and moments produced by the fins is studied.

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.

F-14A High-Angle-of-Attack Characteristics

Journal of Aircraft, 1976
The F-14 has demonstrated that fighter aircraft can be designed to have no lift curve break or angle-of-attack limitation. The maneuver flight envelope, therefore, has been expanded beyond what had traditionally been considered possible. The value of this high alpha capability in the dogfight arena has been convincingly demonstrated in flight.

High Angle of Attack Aerodynamics and Aerothermodynamics

44th AIAA Aerospace Sciences Meeting and Exhibit, 2006
Capability of some state-of-the-art CFD (Computational Fluid Dynamics) codes in predicting the high angle of attack flow characteristics in hypersonic flow regime was studied by comparing the predicted numerical results with available flight and ground test data.

Gust Response at High Angles of Attack

AIAA Journal, 2019
The responses of a NACA0012 airfoil and a large-aspect-ratio wing, subjected to gust excitation about high mean angles of attack, close to stall, are presented here.
