Abstract

The design of inlets and nozzles and their interactions with the airplane may account for a large percentage of the total drag of modern high-performance aircraft. This paper describes the inlet/airframe interactions program and the flight tests conducted at the Dryden Flight Research Facility of the NASA Ames Research Center. Inlet-drag and lift data from a 7.5-percent-scale wind-tunnel model are compared with data from an F-15 airplane with instrumentation to match the model. Pressure coefficient variations with variable cowl angles, capture ratios, and angles of attack are examples of flow interactions presented. Data are presented for Mach numbers of 0.6, 0.9, 1.2, and 1.5.
