Martin Model 262 Convoy Fighter: The Naval VTOL Turboprop Project of 1950

The Martin Model 262 was an unconventional turboprop VTOL aircraft proposal submitted to the US Navy’s convoy fighter competition of 1950, which ultimately produced the Convair XFY-1 Pogo and Lockheed XFV-1 Salmon. It was a swept-wing aircraft with triple vertical tails powered by an Allison XT-40-A-8 turboprop engine driving 16 ft contra-rotating propellers. The launch […]

Early Lockheed XF-90 Concepts — the L-153, L-167 and L-169 Studies

The Lockheed XF-90 was built in response to a 1945 Air Force requirement for a long range penetration fighter and bomber escort. It was an attractive aircraft heavily influenced by the company’s experience with the P-80, sharing a similar intake and low wing configuration. However, it was designed to operate at higher speeds, with a […]

Verticraft Tri-Service VTOL Prototype Transport Aircraft

The Verticraft Verticar was a little known VTOL aircraft design belatedly submitted to the Navy in connection with the Tri-Service Assault Transport competition of 1961. This competition was born of a common requirement by the United States Army, Navy and Air Force for a V/STOL aircraft that could augment helicopters in transport-type missions, specifically a […]

Ljungstrom Internal Propulsion Aircraft Projects (1928)

In 1928, Olof Ljungstrom of Detroit, Michigan submitted a pair of unusual aircraft proposals to NACA which featured boundary layer removal via a primitive form of jet engine, in which a piston engine drove an axial flow turbine blower inside the aircraft. The power plant is reminiscent of that used by the Caproni Campini N.1, […]
