High temperature rake for suspersonic flow

摘要

An apparatus measuring the temperature and/or pressure of an exhaust gas plume from a supersonic military jet engine. The apparatus includes a rotatable airfoil having one or more sensors that are impinged by the exhaust gas flow path prior to the exhaust gas flowing over the airfoil. At least one base is attached and adapted to be mounted to a supporting surface for locating the airfoil rearward of the exhaust gas plume.
