要約

Results of comprehensive numerical and experimental investigations of isolated bypass nozzles with separate exhaustion of the flows in the first (gas generator) and second (fan) circuits of the turbofan engine with different bypass ratios are reported. Rational geometric parameters of the nozzles, which ensure the minimum thrust losses, are determined. The effects of the Mach number of the external flow, pressure ratio in the circuits, and presence of a pylon are investigated. The characteristics of bypass engine nozzles with separate exhaustion of the flows and with their mixing are compared with due allowance for friction, pressure drag, and internal thrust losses.
