Lockheed XFV

When Lockheed XFV -1 Salmon is one developed in the USA in the 1950s, single-seat tail starters for Abfangjagd. The additional name Salmon was not officially assigned, but is probably due to the name of the test pilot Herman "Fish" Salmon. In most cases, the machine was, however, addressed as Pogo, although the name was officially awarded to the competitors draft Convair XFY -1. Development director was Clarence Johnson, Project Number Lockheed was 081-400.

The machine was based on a completely unconventional concept. To start rested the FV-1 on a small chassis at the rear tail. Two opposing, by a turboprop engine driven propellers should lift the aircraft vertically into the air. Then the transition to horizontal flight condition was provided. The recovery process should proceed in reverse order.

Development began in 1947, when the U.S. Navy and Air Force, from a scenario by Soviet attacks annihilated airports, a fighter aircraft called with minimum space requirements for starting and landing. Similar approaches were already at the end of World War II at Focke -Wulf and Heinkel. In addition to Lockheed XFV -1 is a development contract has been awarded for the Convair XFY -1. The XFV -1 was an all-metal mid-wing aircraft with trapezoidal wings. The tail unit consisted of cross-shaped surfaces.

For the flight tests XFV -1 was temporarily equipped with a rigid conventional spur wheel chassis, since a vertical takeoff was not possible because of insufficient engine power. The machine started as on 23 December 1953 its first flight. Transitions from horizontal to vertical flight mode and back were carried out at a safe altitude, without a landing was attempted. These flight tests, which were carried out by the experienced test pilot Herman Salmon, showed that for a normal pilots under difficult conditions this process would be extremely risky.

A total of 32 flights were carried out before the project was canceled in June 1955. In the USA there were then further developments vertically during takeoff aircraft that remained more or less unsuccessful. Only Hawker Siddeley Harrier proved that the suitability of a VTOL aircraft.

The only prototype has been preserved and is located in the U.S. Naval Air Museum in Pensacola.
