Analysis and Characterization of Measured Aerodynamic Loading on a Tactical Missile.
Abstract
A tactical missile instrumented with pressure and acceleration sensors was flown on a fighter aircraft to help characterize the "in carriage" flight environment. The pressure data have been analyzed with various techniques to determine if a simple, yet appropriate, model can be used to model forces applied to a structural finite element model. Analysis has revealed a nearly uniform "convection" of narrow-band random forces along the missile, indicating a highly coherent aerodynamic structure. The circumferential distribution of the standard deviation of measured pressures which tend to "swirl" along the missile seem to indicate the existence of shed vortex-related "swirl" of the aerodynamic excitation.
