Army's three YHC-1As were powered by pairs of GE-T-58 engines. Army would be able to divert funds for the development of the rival V-114 helicopter, which was also a turbine-powered tandem rotor design but substantially larger than the V-107. Spenser, the cutback had been enacted in order that the U.S. However, this order was later decreased to three helicopters according to aviation author Jay P. Army had awarded a contract to Vertol for the construction of ten production-standard aircraft based on the V-107, which were designated YHC-1A. During June 1958, it was announced that the U.S.

In order to garner publicity for the newly developed rotorcraft, it was decided to use the prototype to conduct a series of publicised flight demonstrations during a tour across the United States and several overseas nations. On 22 April 1958, the V-107 prototype performed its maiden flight. During that year, construction of a prototype, powered by a pair of Lycoming T53 turboshaft engines, each one being capable of producing 877 shp (640 kW), commenced. During 1956, the new design received the internal company designation of Vertol Model 107, or simply V-107 this rotorcraft differed from its predecessors by harnessing the newly developed turboshaft engine instead of piston-based counterparts. During 1955, Piasecki was officially renamed as Vertol Corporation (standing for vertical take-off and landing) it was around this time that work commenced on the development of a new generation of tandem rotor helicopter. The commercial version of the rotorcraft is the BV 107-II, commonly referred to simply as the "Vertol".ĭuring the 1940s and 1950s, American rotorcraft manufacturer Piasecki Helicopter emerged as a pioneering developer of tandem-rotor helicopters perhaps the most famous of these being the piston-powered H-21 "Flying Banana", an early utility and transport helicopter. Other export customers for the type included Japan, Sweden, and Saudi Arabia. Canada operated the Sea Knight, designated as CH-113 the type was used predominantly in the SAR role until 2004. Several overseas operators acquired the rotorcraft as well. The Sea Knight also functioned as the US Navy's standard medium-lift utility helicopter prior to the type being phased out of service in favor of the MH-60S Knighthawk during the early 2000s. The USMC also used the helicopter for combat support, search and rescue (SAR), casualty evacuation and Tactical Recovery of Aircraft and Personnel (TRAP). The Sea Knight was operated by the USMC to provide all-weather, day-or-night assault transport of combat troops, supplies and equipment until it was replaced by the MV-22 Osprey during the 2010s. Known colloquially as the "Phrog" and formally as the "Sea Knight", it was operated across all US Marine Corps' operational environments between its introduction during the Vietnam War and its frontline retirement during 2014. During 1961, the US Marine Corps (USMC), which had been studying its requirements for a medium-lift, twin-turbine cargo/troop assault helicopter, selected Boeing Vertol's Model 107M as the basis from which to manufacture a suitable rotorcraft to meet their needs. During June 1958, the US Army awarded a contract for the construction of ten production-standard aircraft, designated as the YHC-1A, based on the V-107 this initial order was later cut down to three YHC-1As though.
It was envisioned as a successor to the first generation of rotorcraft, such as the H-21 "Flying Banana", that had been powered by piston engines in its place, the V-107 made use of the emergent turboshaft engine. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing.ĭevelopment of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. The Boeing Vertol CH-46 Sea Knight is an American medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. Japan Ground Self-Defense Force (historical).
