CH-53A
The CH-53 Sea Stallion (Sikorsky S-65) is an American family of heavy-lift transport helicopters designed and built by the American manufacturer Sikorsky Aircraft. It 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 basically a scaled-up S-61R fitted with twin General Electric T64 turboshaft engines and the dynamic system 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 Vietnam theatre; the CH-53 quickly proved its value for moving heavy payloads, particularly in the recovery of damaged aircraft. Several variants of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The less common MH-53E Sea Dragon fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and perform 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. Development Background The CH-53 was the product of the U.S. Marines' "Heavy Helicopter Experimental" (HH(X)) competition begun in 1962. Sikorsky's S-65 was selected over Boeing Vertol's modified CH-47 Chinook version. The prototype YCH-53A first flew on 14 October 1964.

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

S-64
The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter. It is the civil version of the United States Army's CH-54 Tarhe. It is currently produced as the S-64 Aircrane by Erickson Inc. Development Under Sikorsky The Sikorsky S-64 was designed as an enlarged version of the prototype ''flying crane'' helicopter, the Sikorsky S-60. The S-64 had a six-blade main rotor and was powered by two Pratt & Whitney T73, Pratt & Whitney JFTD12A turboshaft engines. The prototype S-64 first flew on 9 May 1962 and was followed by two further examples for evaluation by the German armed forces. The Germans did not place an order, but the United States Army placed an initial order for six S-64A helicopters (with the designation CH-54 Tarhe, YCH-54A Tarhe). Seven S-64E variants were built by Sikorsky for the civil market.

CH-54
The Sikorsky CH-54 Tarhe is an American twin-engine heavy-lift helicopter designed by Sikorsky Aircraft for the United States Army. It is named after Tarhe, an 18th-century chief of the Wyandot Indian tribe whose nickname was "The Crane". The civil version is the Sikorsky S-64 Skycrane. Development Work on what would become the CH-54 can be traced back to Sikorsky's earlier activities with "sky-crane" helicopters, particularly the piston-engined Sikorsky S-60 of the late 1950s. Following the end of the Korean War, the United States Army sought to procure a successor to the Sikorsky CH-37 Mojave, an early piston-engined heavily lift helicopter; being aware of this need, Sikorsky were keen to fulfil it. The company was already working on the Sikorsky S-64 Skycrane, a civil-orientated heavy lift rotorcraft that was designed specifically for the purpose of carrying large payloads externally; the development of a military-configured derivative was viewed as a natural option.

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense.

Special Operations
Special operations (S.O.) are military activities conducted, according to NATO, by "specially designated, organized, selected, trained, and equipped forces using unconventional techniques and modes of employment". Special operations may include reconnaissance, unconventional warfare, and counter-terrorism actions, and are typically conducted by small groups of highly-trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as " special forces". History Australia In World War II following advice from the British, Australia began raising special forces. The first units to be formed were independent companies, which began training at Wilson's Promontory in Victoria in early 1941 under the tutelage of British instructors. With an establishment of 17 officers and 256 men, the independent companies were trained as "stay behind" forces, a role that they were later employed in against the Japanese in the South West Pacific Area during 1942†...

Combat Search And Rescue
Combat search and rescue (CSAR) are search and rescue operations that are carried out during war that are within or near combat zones. A CSAR mission may be carried out by a task force of helicopters, ground-attack aircraft, aerial refueling tankers and an airborne command post. The USAF HC-130, which was introduced in 1965, has served in the latter two roles. History The First World War was the background for the development of early combat search and rescue doctrine, especially in the more fluid theaters of war in the Balkans and the Middle East. In the opening fluid stages of the First World War the Royal Navy Air Service Armoured Car Section was formed with armed and armoured touring cars to find and pick up aircrew who had been forced down. When trench warfare made this impossible the cars were transferred to other theatres, most notably the Middle East. In 1915, during the First World War, Squadron Commander Richard Bell-Davies of the British Royal Naval Air Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
