NASA's Advanced Vertical Take-off and Landing Aircraft Concepts
NASA's Langley Research Center has developed an inexpensive, long endurance vertical takeoff and landing UAV. It is capable of flying for 24 hours, landing in a 50 x 50 zone, and can be loaded into the back of a cargo van for easy transport. In addition, it can land in an either horizontal or vertical flight configuration. The vehicle can be used in any application where UAVs are needed to take off from, or land in, an unprepared landing area.
