Verification Test of the AEDC High Alpha Roll Dynamics System

Abstract

A test was conducted to evaluate the new AEDC High Alpha Roll Dynamics System for large models and obtain scaling parameter information. Data were obtained at Mach numbers 0.22 thru 1.15 for a Reynolds number per ft range of 690,000 through 2,500,000, at angles of attack -5 to 25 deg, and spin rates up to approximately ten thousand RPM. The model configurations (L/D of 10, D = 4.5 in.) included the Basic Finner and the Modified Basic Finner. Instrumentation included a new four-component balance, tachometer, brake pad thermocouple and a microprocessor-based controller for the turbine/clutch/brake sequencing and for interfacing with the PWT computer system.
