Air Intake Aerodynamics,

Abstract

Effective operation of airbreathing missiles is strongly dependent on the efficiency of the air intake system and its ability to supply the engine with air of adequate quality at all required flight conditions while minimising any undesirable effects that the intakes may have on the overall aerodynamic characteristics of the missile. This paper describes the role of the intake in the propulsion system of turbojet and ramjet powered missiles and addresses both the internal and external aerodynamic aspects of the induction system. The features of various types of air intake commonly used for subonic and supersonic operation are discussed. The causes and effects of flow instability and flow non-uniformity at engine entry are considered and the operational relationship between the engine intake is shown. Three major aspects of intake installation are discussed: the influence of the missile body flowfield on internal performance; the forces and moments generated by the internal aerodynamic characteristics of the missile.
