X-Plane 10 Lippisch DM-1 Flying Triangle 1.0.1. In 1944, Dr. Alexander Lippisch proposed the ramjet powered delta wing P13a interceptor. In order to evaluate the aerodynamic performance of this radical design, Lippisch worked with the Darmstadt and Munich Akaflieg (aerodynamic engineering technical universities) to build the DM-1 glider. The DM-1 is a pure delta wing design with no separate fuselage and the pilot seated in a large vertical stabilizer. It was designed to be launched by aircraft piggy-back, tow or rocket boost. The construction of the DM-1 was not complete by the end of WWII but the allies asked the students at Darmstadt and Munich Akaflieg to finish the aircraft in order to allow further research. The completed aircraft was taken to the US and evaluated by NACA in wind tunnel tests. The results of those tests contributed to future work on delta wing designs including the Convair XF-92, F-102 Delta Dagger and F-106 Delta Dart. This X-Plane model recreates the DM-1 glider using data from the postwar analysis, historic documentation and the National Air and Space Museum (who currently hold the aircraft).
