Efficiency of the introduction the intermediate heating in cycle of afterburning turbofan

Abstract

It is shown that in a afterburning turbofan for effi-cient use of the intermediate the heating at ramjet regime of working for the reason of the increase the consumption of the air through the external circuit by reduction of the diametrical sizes the internal circuit at conservation of the degree increasing of the pressure of the fan and diamet-rical sizes of the external circuit necessary to use as crite-rion to efficiency the maximum of the degree the reduc-tion of the pressure in of the internal circuit, but the de-gree of increasing of the pressure in cycle to increase be-fore ensuring of the absolute maximum this the criterion to efficiency.
