Sikorsky MH-53 Pave Low is an American search and rescue military helicopter designed for the US Air Force by the American aircraft manufacturer Sikorsky Aircraft.
The helicopter model Sikorsky MH-53 Pave Low was designed by American aircraft manufacturers in the first half of the 60s of the last century, while the aircraft was developed solely based on the defense order of the US Air Force. The US military command intended to use this aircraft as a landing and search and rescue helicopter, and, as a rule, this aircraft was not used for open combat due to its weak weapons, however, if necessary, it could provide fire cover from the air.
The helicopter is a fairly massive aircraft. Its length is 28 meters, with a height of 7.6 meters and the main rotor diameter of about 21.9 meters, which in turn exceeded most of the previously developed aircraft of this type. Despite the visually large size, the Sikorsky MH-53 Pave Low helicopter has high maneuverability and accelerates to fairly high speeds, comparable to modern aircraft of this type and class, which in turn has become one of the reasons for the long operation of these machines.
Onboard the helicopter Sikorsky MH-53 Pave Low, depending on the modification, could carry up to 55 people, which in turn was very effective, also, the maximum flight range of this air blower is also quite impressive, amounting to about 1100 kilometers, which, in turn, allowed for special operations even in regions remote from the military base. Besides, if necessary, Sikorsky MH-53 Pave Low helicopters could refuel in the air, which provided a wide range of capabilities.
Depending on the situation, the Sikorsky MH-53 Pave Low helicopter could also play the role of a transport vehicle, carrying up to 5500 kilograms of payload on board, which was also actively used in operations in the US Air Force.
As a power unit in the aircraft of the Sikorsky MH-53 Pave Low model, two T64-GE-100 turboshaft aircraft engines are used, each of which is capable of providing the power of 4330 hp, which ensured both high load capacity and a sufficiently high flight speed of this aircraft apparatus, which at maximum values is about 315 km \ h.
