Supercavity and double-cavity pattern at zero and non-zero angle of attack were obtained.
The extended linearization of nonlinear systems is used to design flight control systems at high angle of attack.
When a fighter aircraft or missile flies at high angle of attack(AOA), asymmetric vortexes are produced from the forebody and induce strong side force and yawing moment.
It is found that the variation of planforms and geometrical parameters can effect only the drag reduction but little to the low lift in low angle of attack condition.
The aerodynamic drag and lift of javelin increase with angle of attack.
This paper introduces two methods to get the virtual sensor signal of angle of attack and sideslip angle: Nonlinear Observer method and INS/GPS method.
The aerodynamic characteristics of the free wing are investigated in this paper. The wind tunnel test results shows that the control of the angle of attack of the fre…
There are two shedding modes along the slender axes when the angle of attack is very high. The Karman vortex shedding region is located in afterbody while the nose vortices region is near the apex.
The influence of nodal points interval of angle of attack and order of spline function on estimation results is also researched.
The transonic turbulent flow around a blunt nosed and short body at large angle of attack was calculated and analysed by using numerical simulation method to solve the full N S equations.
By changing the attitude of the wing (angle of attack withrespect to the wind) can the lift force be made larger or smaller.
The fore-body with sharp section angle can produce direction stability at middle-higher angle of attack in the case of side-slip.
The flow visualization and measurement technology were used to study the flow separation, development of mass vortex and flow control mechanism of triplane at large angle of attack in a water tunnel.
As seen above, the design angle of attack for the second segment is10 deg.
