Abstract : A limited performance and flying qualities validation of thee SGM2-37 powered sailplane was conducted in order to verify contract requirements and to evaluate the overall capability of the aircraft to satisfy mission requirements. The SGM2-37 aircraft meets all contract requirements except for exceeding the maximum takeoff ground run of 1000 feet; the minimum sink rate 240 rate feet per minute, exceeding the approach glide slope of 7 to 1 and failing to achieve a wings level stall speed between 35 and 45 mph. Failure to meet these requirements was not objectionable and did not detract from the operational capability of the aircraft. Problems with cockpit control movement of the left seat airbrake handle and with the control stick were identified along with eratic and inaccurate fuel quanitity indicator displays.
