Three-dimensional turbulent flow code calculations of hot gas ingestion

Abstract

The development of short takeoff, vertical landing (STOVL) aircraft has historically been an experiencebased endeavor. In this study, a three-dimensional turbulent flow computational fluid dynamics (CFD) code was used to calculate the hot gas environment around a STOVL aircraft operating in ground proximity. Preliminary calculations are reported herein for a typical STOVL aircraft configuration to identify key features of the flowfield and to demonstrate the capability of a current three-dimensional CFD code to calculate the temperature of the gases ingested at the engine inlet for typical flow and geometric conditions.
