CREARE LLC — National Aeronautics and Space Administration SBIR Phase I: S3

Description

Long-term monitoring of Titanrsquo;s atmosphere and planetary surface requires a robust autonomous vehicle capable of interacting with Titanrsquo;s heterogeneous surface and profiling its chemically dynamic atmosphere. Creare proposes the Titan Ringlet, a drone capable of vertical takeoff and landing (VTOL) that can transition to horizontal flight to extend the range beyond that of a typical multirotor vehicle. VTOL capabilities simplify the interaction of the vehicle with the planetary surface and enable true vertical profiling of the atmosphere, while the ability to transition to horizontal flight increases the spatial range of possible observations. Crearersquo;s drone utilizes a novel nonplanar wing geometry and mechanically simple controls without the need or complexity of traditional fixed-wing control surfaces. The drone packs efficiently into an aeroshell for safe entry into the Titan atmosphere and then separates from the aeroshell for a precision vertical landing on the surface. Compared to a pure rotorcraft (vertical flight), the fixed-wing cruise flight mode of Crearersquo;s drone increases maximum range by three times, increases maximum endurance by two times, and increases maximum altitude by four times.
