Investigation of Transient Induced Aerodynamics in a Moving Deck Environment.

Abstract

Operating a V/STOL aircraft in ground effect can greatly alter the aerodynamic forces and moments acting on the aircraft. By introducing a moving ground plane, such as the deck of a DD963 class destroyer, the complexity of the resulting flow field is significantly increased. This added complexity makes it even more difficult to perform successful shipboard takeoff and recovery operations. In order to fully utilize the potential shipboard operational capabilities of V/STOL aircraft a better understanding of these phenomena is required. To accomplish this, the effects of basic single axis deck motions must be examined. Analysis of these independent deck motions (heave, pitch, roll) enable the development of prediction techniques applicable to a preliminary design environment. These methods provide the designer a tool for estimating the transient induced aerodynamics acting on a V/STOL aircraft in a moving deck environment. Data for the three-fan subsonic V/STOL configuration was selected for study.
