Computational Investigation Of Slot Blowing For Fuselage Forebody Flow Control
نویسنده
چکیده
This paper presents a computational investigation of a tangential slot blowing conccpt for generating lateral control forces on an aircraft fuselage forcbody. The effects of varying both the jet width and jet exit velocity for a fixed location slot are analyzed. This work is aimcd at aiding rrscarchcrs in designing future experimental and compm tational models of tangential slot blowing. The primary influence on the resulting side force of the forcbody is seen to be the jet mass flow rate. This influence is insensitive to different comhinntions of slot widths and jct vclocities over tlir range of variablcs considered. Both an actuator planc and a n overset grid technique are used to model the tangcntial slot. Tile overset method succrssfully resolves tlic &tails of the actual slot gcometrg, extending t h generali ty of t,lic numrricnl rnclliod. The actnator plnnc conccpt prdicts sidc forccs similar tn those produced l q resolving tlir actual slot geomct,ry. -

Duty cycle modulation of the alternating blowing from two opposite facing plasma actuators on the leeward surface near the apex of a cone of semi-apex angle 10o to control the mean lateral force and moment and the flow control mechanism are presented. The pressure distributions over the cone forebody are measured by steady and unsteady pressure-transducers. The experiments are performed in a 3....

متن کاملExperimental Investigation into the Hydrodynamics Effects of Slot Film Cooling on a Cylindrical Model
An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

Forebody pneumatic vortex control has previously been demonstrated through full-scale flight test to be effective for directional control of aircraft at low Mach number and high angle-ofattack flight conditions. The objective of the present research was to investigate the suitability of two-axis (wing, and vertical tail) pneumatic vortex lateral/directional control of a current fighter-type air...
