Abstract:

Experimental investigations of the feasibility of directing missile thrust by controlling ambient airflow through ports in overexpanded nozzles have been conducted by the Naval Weapons Center and an NWC-sponsored contractor. Chandler Evans, Inc. The present analytical effort studied boundary-layer thrust vector control BLTVC technology with the following specific objectives 1 Development of analytical or semi-empirical descriptions of the dominant phenomena that characterize the BLTVC flow field 2 Derivation of similarity parameters that affect BLTVC performance 3 Development of preliminary guidelines for flight-environment simulation with ground experiments and 4 Generation of design charts that would be useful for BLTVC performance evaluation. The results of the study include identification of areas that require investigation in order to establish a design suitable for mission applications.
