Abstract:

A cooperative effort between Hughes Missile Systems Company, NASA Langley Research Center and AF Wright Laboratory was performed to evaluate the adequacy of simplified aerodynamic predictive methods for estimating the leeside separation of weapons from a hypersonic air vehicle. Aerodynamic test results were obtained at the NASA Mach 6 wind tunnel facility Reference 1, where typical store-shaped test models were traversed in the shielding influence of an inclined flat plate. These data largely verify that aerodynamic predictive methods, based on Newtonian impact line-of-sight approximation methods, yield representative force and moment characteristics acting on stores during their leeside carriage and upward eject launch. Based on these predicted data, simulated leeside launch trajectories of advanced submunition weapons show that they can be safely separated from a carriage vehicle at hypersonic speeds.
