Engineering Studies into Vertical Lift Planetary Aerial Vehicles

Abstract : NASA Ames Research Center has been investigating various rotary-wing aeromechanics and proof-of-concept issues underlying the development of vertical lift aerial vehicles for planetary science missions. These engineering studies include: hover performance measurements of an isolated rotor in simulated Mars surface atmospheric conditions; radio-controlled coaxial helicopter flight tests supporting the investigation of Mars rotorcraft technologies; small-scale unducted- and ducted-fan hover tests that provide insight into possible VTOL aircraft for exploration of Titan; hybrid airship proof-of-concept testing that illustrates flight control and forward flight performance issues inherent in airships designed for flight in the atmosphere of Venus.
