Artificially Induced Boundary-Layer Transition on Blunt-Slender Cones Using Distributed Roughness and Spherical-Type Tripping Devices at Hypersonic Speeds

Abstract

Research directed toward establishing criteria for distributed roughness-type boundary-layer trips on blunt-slender cones has been conducted in the AEDC/VKF at Mach numbers from 8 to 13. Results indicate that distributed roughness trips are superior to spherical-type trips in that equally effective distributed roughness trips are one-fifth as high and produce substantially smaller flow-field disturbances. Criteria are defined for optimum utilization of distributed roughness trips.
