The Grumman-patented Sto-Wing aftwards-folding wing folding system, pioneered on the Grumman F4F-4 Wildcat, has been used since World War II on a number of Grumman-designed carrier aircraft, [4] [5] a version of which is still in use in the 21st century on the Grumman E-2 Hawkeye shipboard airborne early warning (AEW) aircraft and its C-2 ...
The C-2 Greyhound, a derivative of the Northrop Grumman E-2 Hawkeye, shares the folding "Sto-Wings" and engines with the E-2, but has a widened fuselage with a rear loading ramp. The first of two prototypes flew in 1964. After successful testing, Grumman began production of the aircraft in 1965.
A new version, the F4F-4, entered service in 1941 with six machine guns and the Grumman-patented Sto-Wing folding wing system, [47] [48] which allowed more aircraft to be stored on an aircraft carrier, increasing the number of fighters that could be parked on a surface by more than a factor of 2. The F4F-4 was the definitive version that saw ...
The prototype first flew on July 11, 1963, and featured folding wings for trailering and ease of storage. Bede formed a company, Bede Aviation Corporation, based in Cleveland, Ohio, to produce the aircraft, but the BD-1 never entered production as a certified aircraft. At that time, the FAA was hesitant to certify a light aircraft with folding ...
The Douglas DT bomber was the Douglas Aircraft Company's first military contract, forging a link between the company and the United States Navy.Navy Contract No. 53305 of April 1, 1921, required only 18 pages to set out the specifications that resulted in the purchase of three DT (D for Douglas, T for torpedo) folding-wing aircraft.
The wing was mounted lower on the fuselage and was able to be hydraulically or manually folded, with each panel outboard of the undercarriage bay folding backwards from pivoting on a specially oriented, Grumman-patented "Sto-Wing" diagonal axis pivoting system much like the earlier F4F, with a folded stowage position parallel to the fuselage ...
Grumman E-1B Tracer of RVAW-110 after service aboard USS Franklin D. Roosevelt in 1976, showing the Grumman-patented Sto-Wing wing folding arrangement As one of the first carrier based early warning aircraft, the E-1 Tracer served from 1960 to 1977, [ 1 ] although considered only an interim type, being replaced by the Grumman E-2 Hawkeye in the ...
Grumman's design (model G-89) was for a large high-wing monoplane with twin Wright Cyclone R-1820 nine cylinder radial engines, a yoke type arrestor hook and a crew of four. Both the two XS2F-1 prototypes and 15 S2F-1 production aircraft were ordered at the same time, on 30 June 1950.
