Abstract
An analytical method to predict the effects of rotor downwash on engine jet was proposed to investigate the flow pattern of helicopter engine jet using generalized wake equation. First, free wake analysis was carried out to calculate the rotor wake geometry and the downwash around the engine jet space. Then engine jet path, cross section shape and physical variants were calculated and analysed. Finally, an example was given to show that the method can be used to predict the temperature at the core of a jet and the temperature distribution in various jet section of a helicopter.
