Development of Intake Measurement Rake for an Aircraft

It is requested to design a parameter measurement device(called "measurement rake") for pressure and temperature transducers in the aircraft intake flow field,for an aircraft design evaluation flight test application.Since the special installation environment,the structure design difficulties and requirements have never been met before.This paper describes the device design conditions and the innovation structure in detail.Through the strength calculation and vibration qualification,the measurement rake was permitted to use on the aircraft finally.The instrumentation of the aircraft design evaluation flight test was completed successfully.In other aircraft flight tests,this intake measurement rake structure design has been widely adapted.
