The helicopter was designated "CH-53A Sea Stallion" and delivery of production helicopters began in 1966. [5] The first CH-53As were powered by two General Electric T64-GE-6 turboshaft engines with 2,850 shp (2,125 kW) and had a maximum gross weight of 46,000 lb (20,865 kg), including 20,000 lb (9,072 kg) in the payload.
The Sikorsky CH-53K King Stallion (Sikorsky S-95) [2] is a heavy transport helicopter designed and produced by Sikorsky Aircraft.The King Stallion is an evolution of the long running CH-53 series of helicopters which has been in continuous service since 1966, and features three up-rated 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than its predecessors.
The Block 2 aims for a payload of 22,000 lb (10,000 kg) with 4,000 ft (1,200 m) and 95 °F (35 °C) high and hot hover performance, eventually increased up to 6,000 ft (1,800 m), to carry the Joint Light Tactical Vehicle; maximum takeoff weight would be raised to 54,000 lb (24,500 kg).
That weight exceeded the maximum payload of 9.1 tonnes (20,000 lb) at an altitude of 2,600 metres (8,500 ft) of the U.S. military's Sikorsky CH-53E. [ 4 ] The Mi-26 was located through Skylink Aviation in Toronto , which had connections with a Russian company called Sportsflite that operated three civilian Mi-26 versions called "Heavycopters".
As of 2014, it continues to hold the helicopter record for highest altitude in level flight at 11,000 m (36,000 ft), which it set in 1971, [5] as well at the fastest climb to 3,000, [6] 6,000, [7] and 9,000 [8] m (10,000, 20,000, and 30,000 ft). On 20 April 1965, a CH-54A equipped with a people pod lifted 90 people, comprising its crew of three ...
Derived from the SE 3150, it was designed for high altitude operations using a 650 kW (870 hp) Turbomeca Astazou IIIB turboshaft, derated to 410 kW (550shp). This derivative still holds the absolute altitude record for all types of helicopters since 1972: 12,442 m. HB 315B Gaviao Brazilian licence-built version of the SA 315B Lama. [17] HAL Cheetah
While the CH-47 Chinook is a large helicopter by American standards, its payload of 28,000 lb (13,000 kg) is dwarfed by the huge Soviet-Russian heavy-lift helicopters such as the Mil Mi-26, with 44,000 lb (20,000 kg) payload, and the experimental Mil V-12, with 55,000 to 88,000 lb (25,000 to 40,000 kg) payload. For a long time Boeing and the US ...
Mil V-12 at the Central Air Force Museum. Design studies for a giant helicopter were started at the Mil OKB in 1959, receiving official sanction in 1961 by the GKAT (Gosudarstvenny Komitet po Aviatsionnoy Tekhnike - State Committee on Aircraft Technology) instructing Mil to develop a helicopter capable of lifting 20 to 25 tonnes (22 to 28 short tons).
