Aircraft Vertical Takeoff and Landing

摘要

NASA's Langley Research Center developed an inexpensive, long-endurance, vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV). It is capable of flying for 24 hours, landing in a 50 × 50 zone, and can be loaded into the back of a cargo van for easy transport. In addition, it can land in either a 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. Commercial applications where extended-mission UAV capabilities are beneficial include law enforcement, fire-fighting, crop surveys, pipeline surveys, or oil field management.
