Russian Engineering Research Aims and scope

Abstract

An engineering model of a plug nozzle is developed. The nozzle is intended for use in the engine of a prospective supersonic civilian airplane. On the basis of the model, two plug profiles are obtained for different nozzle configurations. The thrust is also estimated, taking account of the internal losses and the external aerodynamic drag of the casing. Preliminary estimates of the loss of thrust are made, taking account of the same factors. The proposed model and the results obtained may be useful in selecting the best engine structure and in optimizing the control program for the power unit.
