Design and Development
The Cutlass was Vought's entry to a U.S. Navy competition for a new carrier capable day fighter opened on 1 June 1945. Former Messerschmitt AG senior designer Waldemar Voigt, who supervised in Nazi Germany the development of numerous experimental jet fighters, contributed to its design with his experience in the development of the Messerschmitt P.1110 and P.1112 projects. The requirements were for an aircraft that was able to fly at 600 miles per hour (970 km/h) at 40,000 feet (12,000 m). The design featured broad chord, low aspect ratio, swept wings, with twin wing-mounted tail fins either side of a short fuselage. The cockpit was situated well forward to provide good visibility for the pilot during aircraft carrier approaches. The design was given the company type number of V-346 and then the designation F7U when it was announced the winner of the competition.
Pitch and roll control was provided by elevons, though Vought called these surfaces "ailevators" at the time. Slats were fitted to the entire span of the leading edge. All controls were hydraulically-powered. The very long nose landing gear strut required for high angle of attack takeoffs was rather weak, and a collapse could seriously jeopardize the pilot's safety. The F7U was also largely let down by its underpowered Westinghouse turbojets, an engine that some pilots quipped, "put out less heat than the same company's toasters." Naval aviators referred to the F7U as the "gutless cutlass" or, in kinder moments, as the "praying mantis".

Famous quotes containing the words design and/or development:
“Delay always breeds danger; and to protract a great design is often to ruin it.”
—Miguel De Cervantes (1547–1616)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
