The wing rock problem is generally well known, but the high sensitivity of wing rock to variations in flow conditions and scale effects may not be as well understood. This paper discusses the scale sensitivity in the viscous flow mechanisms that have

Conclusions Based on the convection of thin vortex sheets, it has been shown that aircraft vortices can temporarily intensify in the presence of crosswind shear. An aircraft following another one may, thus, be subjected to a stronger vortex than that

Extensive efforts have been directed toward the development of the means by which the flow separation asymmetry occurring on an axisymmetric slender forebody at very high angles of attack could be controlled in order to improve the agility of advance

Because of the current high interest in low observables planforms, characterized by swept leading-edge and trailing-edge panels, it is appropriate to consider the implications for ground facility testing of models that, because of the existing coupli

When during the ascent through the Earth’ s atmosphere the structural response of an aerospace launch vehicle changes from the usually benign case of the buffet response to wind gusts and air turbulence to the self-excited type, theresponseamplitud

In a series of dynamic stall tests, performed 1968 with a finite-span wing model having a NACA-0012 airfoil section, very unusual C,(a) characteristics were obtained by varying the Reynolds number as well as using fixed and free boundary layer transi

Introduction M ILITARY design trends toward the use of unmanned, nless aircraft have renewed interest in the unsteady aerodynamics of slender wing rock. One important aspect of the problem of wing rock control is the potential impact of typical co

Analysis of rotary balance data on a generic aircraft model revealed the nature of the flow mechanisms present in subscale experiments, which included the existence of support interference. Recent results on the F/A-18 confirmed the existence of a th

When attempting to transfer the forebody flow control technology developed on military aircraft to commercial aircraft, such as the Boeing 1804 SST, additional flow parameters become important. The reason for the complication of the technology transf
