Title Supersonic wing aerodynamic characteristics simulation analysis
Abstract: Form of modern warfare are more and more three-dimensional, so supersonic missile power and accuracy of the increasingly high demand, this means that the supersonic wing must have a high mobility characteristics, have a larger normal overload, that is the main lifting surface supersonic missiles need to be able to produce enough normal force, but also the need to improve the missile lift-drag ratio. Supersonic wing is the main lifting surface supersonic tactical missile, domestic and foreign research data shows that supersonic wing design is crucial to improve the maneuverability of missiles, missile suffered lower resistance, to ensure the stability of missile flight. Supersonic wing lift coefficient, the drag coefficient, lift-drag ratio with supersonic wing aspect ratio, the root is slightly more than the equivalent sweep, airfoil thickness, airfoil shape geometric design parameters and flight Mach number, the flight of the related with the angle of attack. In this paper, through the use of UG, ICEM, FLUENT software for three-dimensional model of supersonic wing establishment, meshing, numerical simulation, research the effects of these parameters on the lift and drag coefficients of supersonic wing, and discuss the advantages and disadvantages of various geometric parameters on the basis of an airfoil.
