The instrumentation of the S-2 aircraft for stability and control flight testing

Abstract

A Navy US-2A aircraft was instrumented for use in stability and control flight testing. Various methods of recording and sensing the aerodynamic parameters necessary to evaluate stability and control flight testing were investigated. An Ampex Series 800 Magnetic Tape Recorder, obtained on a loan basis, was calibrated and installed to provide a means of recording airborne data. Using available equipment, sensing devices were installed in the aircraft and calibrated to measure control forces, control surface position, and normal acceleration. The complete installation provides the means for sensing and recording those aerodynamic parameters most difficult to measure without electronic aids. It also allows for the incorporation of additional sensing and recording devices should they become available.
