Thrust Augmentation for Tomahawk Cruise Missile

Abstract

A multiple orifice canister baseplate was designed for the Tomahawk Cruise Missile to achieve required thrust augmentation characteristics during surface ship and ground launches. This new baseplate will replace the present single orifice baseplate which was analytically determined unsatisfactory under extreme launch conditions. Scaled model tests using room temperature air were conducted and flight test data were utilized to predict the discharge characteristics of new baseplates under the real launch conditions. These discharge characteristics were used in a computer program simulating a Tomahawk launch to predict the launch dynamics and thrust augmentation characteristics. The improved thrust augmentation with the new baseplate will assure a successful Tomahawk missile launch for the full range of ground or ship launch conditions.
