瑞安X-13 Vertijet是一种实验性的喷气动力飞机，可以垂直起飞和降落。它是由瑞安航空公司在1950年代为美国空军建造的。该项目的主要目标是测试可以在小平台或潜艇上运行的纯喷气式飞机的可行性。
The X-13 Vertijet had a delta wing with flat endplates and a single Rolls-Royce Avon turbojet engine that produced 44.6 kN of thrust. The engine had a variable nozzle that could be tilted to provide pitch and yaw control in hover mode. The wingtips had small jets that provided roll control. The nose of the aircraft had a hook and a retractable pole that helped the pilot to align with a vertical trailer bed that served as a landing platform. The trailer could be lowered to horizontal position for ground transportation.
The first prototype of the X-13 Vertijet made its first horizontal flight on December 10, 1955, using temporary landing gear. Later, it performed several transitions from horizontal to vertical flight and vice versa at high altitude. The landing gear was then replaced by a tail-mounted framework that held the aircraft in vertical position on the ground. The second prototype made the first complete cycle of vertical take-off, transition to horizontal flight, transition to vertical flight and vertical landing on April 11, 1957.
The X-13 Vertijet demonstrated the technical feasibility of VTOL jet aircraft, but it had limited practical value due to its low performance, high fuel consumption and complex operation. The project was cancelled in 1957 after two prototypes were built and tested. The two surviving aircraft are on display at the National Museum of the United States Air Force and the San Diego Air and Space Museum.
