VSP Hangar | NASA Dos Samara Concept

File ID#	74
Manufacuter	NASA
Model	Dos Samara
Units	Feet
Description	Concept developed by Mark Moore and Bill Fredericks of NASA Langley. Design goal is to achieve a 24 endurance, highly efficient loiter (L/D>20), while also achieving vertical takeoff at low discloading. Low discloading was desired to satisfy mission goals of operation from a sandy ground environment with low noise, at relatively low power. The unique feature of the Dos Samara is that the mono-blade rotors are driven by synchronized electric pancake hub motors with batteries in the counter balance, with these mono-rotors stopping and locking in transition flight to achieve a sailplane-like cruise. Detailed internal layout includes Satcom, avionics and payload volumes, as well as the hybrid-electric powertrain.
Source Quality	1 - The source material used to create this model was Definitive. This means the VSP model is the definition of the vehicle or part (it was built from the model or the model is the best source of infromation available).
Model Suitability	1 - Accurate OML for detailed aerodynamic analysis or CFD 1 - Check internal layout/volume 1 - OML for wetted areas/drag buildup 1 - Build a display model 1 - Weight and balance 1 - Structures 1 - Cartoon or Pretty Picture
