Boeing Vertol YUH-61

The Boeing Vertol YUH-61 is a military multi-purpose helicopter developed in 1974 by the Boeing Vertol aircraft manufacturing company.

The design of the military multipurpose transport helicopter Boeing Vertol YUH-61 began by American aircraft manufacturers in 1972. The main objective of the creation of this aircraft was a military order, according to which the US Armed Forces needed a multi-purpose aircraft capable of carrying people and cargo on board, as well as being used as a means to carry out special operations, etc.

American aircraft manufacturers managed to quickly implement the project of the aircraft, which was very promising for the US Armed Forces since all the main nuances and requirements of the military command were taken into account and embodied in this helicopter model.

The first test tests of the Boeing Vertol YUH-61 helicopter were conducted by American specialists already in 1974, while the aircraft successfully passed all stages of testing. Despite this fact, the criteria of this aircraft did not satisfy the requirements of the US military command, in particular, the helicopter of the aircraft manufacturer Sikorsky Aircraft turned out to be more acceptable in this regard, and therefore the interest in the design of the Boeing Vertol YUH-61 aircraft almost immediately gone.

Subsequently, the aircraft developers based on the military version of the Boeing Vertol YUH-61 helicopter, a civilian aircraft capable of transporting people and transporting large cargoes. It was assumed that the project could achieve great success, however, due to the rather high cost, the helicopter did not gain popularity, and therefore the project of the Boeing Vertol YUH-61 aircraft could not manifest itself and was finally canceled.

Depending on the layout of the cabin, onboard a helicopter model Boeing Vertol YUH-61 can accommodate up to 20 passengers (the civilian version of the aircraft), as well as two crew members. If necessary, the aircraft can also carry on its board and bulky goods with a total weight not exceeding the maximum take-off weight of this aircraft, which is 8 tons.

The power plant of the Boeing Vertol YUH-61 helicopter consists of two General Electric T700 gas turbine aircraft engines, each of which can develop a thrust of 1540 hp, which allows the aircraft to accelerate to a maximum speed of 290 km / h, with the ability to overcome distances up to 450 kilometers.

Over the entire development period, only 3 aircraft of this model were built by American aircraft manufacturers from the Boeing Vertol company.
