One-Dimensional Model of the Propulsion System Air Intake for a Supersonic Civil Aircraft

Russian Engineering Research Aims and scope

Abstract

The development of a one-dimensional model of the engine’s air intake for a supersonic civil aircraft is discussed. This model determines the air intake’s integral parameters (the flow rate, the total pressure recovery, and the drag), taking account matching with the engine in terms of the flow rate and parameters of the operating fluid under all flight conditions. The model corresponds to a fixed-geometry convergent mixed-compression air intake with a hexagonal input cross section; it contains a wedge with swept edges.
