Vertical Takeoff and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) utilizing the Coanda effect for lift generation have a number of potential benefits, including: (a) the creation of a large aerodynamically-neutral payload\/systems bays, (b) a high payload-carrying ability for its size, and (c) the use of an enclosed rotor, enabling it to withstand contact with its surroundings.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ECoanda effect UAVs have undergone some study, but remain a largely under-investigated and certainly un-optimized VTOL configuration.
