The Effect of a Turbulent Airstream on a Vertically-Launched Missile at High Angles of Attack.
Abstract
The purpose of this thesis is to initiate an investigation of the response of a shipboard surface-to-air missile launched vertically into a region of turbulence at high angles of attack. A review was conducted on the effects of asymmetric vortices, turbulent flowfields, and the marine atmospheric environment on a slender body of revolution. Turbulence mapping of a wind tunnel with installed turbulence-generating grids was conducted using hot-wire anemometry. The resultant turbulence intensities and length scales were analyzed as a function of the downstream distance and the grid mesh-width/bar-diameter ratio. Turbulence intensity was found to decrease, while the length scale increased, with increasing distance from the generating grid. Both the turbulence intensity and length scale increased with an increase in the grid bar diameter. Keywords: Vertical launch, Missile, Turbulence, High angle, Attack, Vortices.
