摘要

A computational and experimental investigation of forebody tangential slot blowing was performed on a generic chined forebody. Reynolds-averaged, Navier-Stokes computations were conducted in conjunction with a low speed wind tunnel test for a forebody at high angles of attack (0 deg <= alpha <=45 deg). Tangential slot blowing was investigated as a means of forebody flow control to generate yawing moment levels capable of overcoming flow asymmetries. The effects of jet mass flow rate and jet longitudinal position were studied. Tangential slot blowing was found to overcome the natural flow asymmetry of the forebody throughout the angle-of-attack range studied.
