A Limited Evaluation of Full Scale Control Surface Deflection Drag (Have FUN)

The Have FUN (FUll Scale Numbers) Test Management Project was conducted at the request of the USAF TPS as an investigation into the drag caused by control surface deflection during dynamic soaring techniques. Forty-three test sorties were performed from 6-23 March 2007 under Job Order Number (JON) M...

Description
Summary:The Have FUN (FUll Scale Numbers) Test Management Project was conducted at the request of the USAF TPS as an investigation into the drag caused by control surface deflection during dynamic soaring techniques. Forty-three test sorties were performed from 6-23 March 2007 under Job Order Number (JON) M07C0200. The six member Have FUN test team from TPS Class 06B performed the testing at the North Base facilities of Edwards AFB. Flight testing gathered sailplane decelerations during control surface deflections and energy height data during the performance of Dynamic Soaring maneuvers and straight glides. Coefficients of drag for each control surface were determined from minimum sink to maneuvering airspeed of the L-23 Super Blanik. The original document contains color images.
