There are two types of equations which fall under this general heading: (1) equation relating control deflection, βc, and attitude angle, ϕi, to the indicated output of the sensor (i.e. angle of attack, acceleration, etc.), and (2) the dynamic equations of the sensors, themselves....
Angle Of AttackConvergenceA steady-flow Euler method is applied to the subsonic leading-edge vortex flow about a 65-deg sharp-edged cropped delta wing at high incidence. Above a critical value of the incidence the numerical procedure fails to fully converge, the solution at successive iterations ...
Dynamic model testing of the X-31 configuration for high-angle-of-attack flight dynamics research High-angle-of-attack flight dynamics of the X-31 configuration were studied using dynamic model test techniques. These tests identified phenomena including... MA Croom,DJ Fratello,RD Whipple,... 被...

The proposed method is first applied to fast evaluation of nearby flows: the baseline flow and sensitivity fields around a NACA 0012 airfoil are used to predict the flow around airfoils with nearby shapes obtained by modifications of the thickness (NACA 0015), the angle of attack and the ...
Experimental Closed-Loop Flow Control of a von Karman Ogive at a High Angle of Attack The asymmetric vortex regime of a von K谩rm谩n ogive with fineness ratio of 3.5 is experimentally studied at a Reynolds number of 156,000. The wake of an axisymmetric bluff body is an ideal candidate f...
The Optimum Angle of Attack of Delta Winglet VortexGenerators on Heat Transfer Performance of Finned Flat Tube Bank with Considering Nonuniform Fin Tempera... To investigate the effects of the angle of attack of delta winglet vortex generators (VGs) on heat transfer performance and pressure drop ...
This approach is straightforward to implement, but as a first line of attack to device modeling and for understanding physical trends, simple analytical results are also of great value. In this paper, a general, system-independent formulation of the parabolic Schrödinger–Poisson equation for a ...
In the present work the flow regime corresponds to 90 km altitude, free-stream Mach number M∞=10 and angle of attack α=25 degrees. To the best of our knowledge, the present study is the first proper comparison of the kinetic equation solution with a DSMC solution for the external high...
