CH-53K
The Sikorsky CH-53K King Stallion (Sikorsky S-95) 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 engines, new composite rotor blades, and a wider aircraft cabin than its predecessors. It is the largest and heaviest helicopter in the U.S. military. The United States Marine Corps plans to receive 200 helicopters at a total cost of $25 billion. Ground Test Vehicle (GTV) testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018, the first CH-53K was delivered to the Marine Corps. On 22 April 2022, it was declared to have passed initial operational capability. Israel has also reportedly ordered the type; other potential export customers include Japan.

Sikorsky CH-53E Super Stallion
The Sikorsky CH-53E Super Stallion is a heavy lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. Developed in the 1970s, it entered service in 1981, and is planned to be in service into the 2030s. It is one of the largest military helicopters in service, and is operated from U.S. Navy ships or from land. The Navy also operates the MH-53E Sea Dragon which fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and performs heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E and enter service in the 2020s. Most of the Super Stallions in service are configured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky CH-53 Sea Stallion
The CH-53 Sea Stallion (Sikorsky S-65) is a family of American heavy-lift transport helicopters designed and built by the American manufacturer Sikorsky Aircraft. The Sea Stallion was originally developed in response to a request from the United States Navy's Bureau of Naval Weapons made in March 1962 for a replacement for the Sikorsky CH-37 Mojave helicopters flown by the United States Marine Corps (USMC). In July 1962, Sikorsky's proposal, which was essentially a scaled-up S-61R fitted with twin General Electric T64 turboshaft engines and the dynamic systems of the S-64/ CH-54, was selected. On 14 October 1964, the YCH-53A performed its maiden flight; the first deliveries of production CH-53s to operational units commenced on 12 September 1966. The first combat use of the type occurred during the following year when it was deployed to the Vietnamese theater; the CH-53 quickly proved its value for moving heavy payloads, particularly in the recovery of damaged aircraft.

Military Transport Aircraft
A military transport aircraft, military cargo aircraft or airlifter is a military aircraft, military-owned transport aircraft used to support military operations by airlifting troops and military equipment. Transport aircraft are crucial to maintaining supply lines to forward bases that are difficult to reach by ground transport, ground or maritime transport, waterborne access, and can be used for both strategic and tactical missions. They are also often used for civilian emergency relief missions by transporting humanitarian aid. Air frames Fixed-wing Military transport aeroplanes are defined in terms of their range capability as strategic airlift or tactical airlift to reflect the needs of the land forces which they most often support. These roughly correspond to the commercial flight length distinctions: Eurocontrol defines short-haul routes as shorter than , long-haul routes as longer than and medium-haul between. The military glider is an unpowered tactical air transp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CH-47 Chinook
The Boeing CH-47 Chinook is a tandem-rotor helicopter originally developed by American rotorcraft company Piasecki Helicopter, Vertol and now manufactured by Boeing Defense, Space & Security. The Chinook is a Military transport helicopter, heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native Americans in the United States, Native American Chinook people of Oregon and Washington (state), Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the Radial engine, piston-engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, some Army officials consider ...

V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-use, tiltrotor military transport aircraft, military transport and cargo aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed Cruise (aeronautics), cruise performance of a turboprop aircraft. The V-22 is operated by the United States and Japan, and is not only a new aircraft design, but a new type of aircraft that entered service in the 2000s, a tiltrotor compared to fixed wing and helicopter designs. The V-22 first flew in 1989 and after a long development was fielded in 2007. The design combines the vertical takeoff ability of a helicopter with the speed and range of a fixed-wing airplane. The failure of Operation Eagle Claw in 1980 during the Iran hostage crisis underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport ...

Sikorsky Aircraft
Sikorsky Aircraft is an American aircraft manufacturer based in Stratford, Connecticut. It was established by the Russian-American aviation pioneer Igor Sikorsky in 1923, and was among the first companies to manufacture helicopters for civilian and military use.

Transmission (mechanics)
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (industrialist), Louis Renault (who founded Renault, Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam engine, steam-powered devices. Applications of these devices included pumps, mill (grinding), mills and Hoist (device), hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations.

Titanium
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide (TiO2), is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
