CONICAL CENTERBODY FOR A TWO STREAM TANGENTIAL ENTRY NOZZLE

摘要

A centerbody for a tangential entry nozzle having a longitudinal axis and a radially outer surface including a frustum portion defining the outer surface of a frustum that is coaxial with the longitudinal axis and flares toward the frustum base th ereof, and a curved portion which is integral with the frustum portion and preferably defines a portion of the surface generated by rotating a circle which is tangent to the frustum po rtion and has a center which lies radially outward thereof about the longitudinal axis. Th e centerbody has a base which includes at least one air supply port extending ther ethrough, and an internal passageway. The frustum portion tapers towards a discharge orifi ce of the internal passageway, and terminates at the plane in which the discharge orifice is located. A fuel-lance that is coaxial with the axis and extends through the base and term inates within the internal passageway provides fuel to the air flow in the centerbody.
