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.

Sikorsky Aircraft
Sikorsky Aircraft is an American aircraft manufacturer based in Stratford, Connecticut. It was established by aviation pioneer Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use. Previously owned by United Technologies Corporation, in November 2015 Sikorsky was sold to Lockheed Martin. History On 5 March 1923, the Sikorsky Aero Engineering Corporation was founded near Roosevelt Field, New York, by Igor Sikorsky, an immigrant to the United States who was born in Kyiv. In 1925, the company name was changed to Sikorsky Manufacturing Company. After the success of the Sikorsky S-38">S-38, the company was reorganized as the Sikorsky Aviation Corporation with capital of $5,000,000, allowing the purchase of land and the building of a modern aircraft factory in Stratford. In 1929, the company moved to Stratford, Connecticut, and it became a part of United Aircraft and Transport Corporation (later United Technologies Corporatio ...

Sikorsky S-60
The Sikorsky S-60 helicopter, a prototype " flying crane", was derived from the S-56 in 1958. Proving to be underpowered, the development of the S-60 led to the larger, turbine-engined Sikorsky CH-54 Tarhe military transport helicopter, and its civil S-64 Skycrane variant, which were already on the drawing board by the time the sole example of the S-60 crashed on 3 April 1961. Design and development In 1958, Sikorsky began designing the S-60 as a prototype " flying crane" helicopter. The S-60 utilized the transmission, rotor system and piston engines from the CH-37/S-56.Donald 1997, p.?Harding 1997, p. 237. The fuselage of the S-60 was a simple "pod-and-boom" design with the engines mounted in side pods and long tailwheel-style landing gear that allowed it to straddle cargoes. The crew cabin was mounted in the nose, with aft-mounted controls for the co-pilot to use during loading and unloading operations. The S-60 had an automatic stabilization system to allow it to hover prec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky CH-37 Mojave
The Sikorsky CH-37 Mojave (company designation S-56) is an American large heavy-lift helicopter of the 1950s. Design and development The S-56 came into being as an assault transport for the United States Marine Corps (USMC), with a capacity of 26 fully equipped Marines. An order for the aircraft was placed in 1951 using the U.S. Navy/U.S. Marine Corps designation of the time of HR2S. The first prototype, the XHR2S-1 flew in 1953 and production deliveries of the HR2S-1 began in July 1956 to Marine Helicopter Squadron One ( HMX-1), with a total of sixty aircraft being produced. The United States Army evaluated the prototype in 1954 and ordered 94 examples as the CH-37A, the first being delivered in summer 1956. All Marine Corps and Army examples were delivered by mid-1960. Army examples were all upgraded to CH-37B status in the early 1960s, being given Lear auto-stabilization equipment and the ability to load and unload while hovering. In the 1962 unification of United States mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarhe
Tarhe (1742–1818) was a leader of the Wyandot people in the Ohio Country. His nickname was "The Crane". He fought American expansion into the region until the Northwestern Confederacy was defeated at the Battle of Fallen Timbers in 1794. Afterwards, he sought accommodation with the United States. The Sikorsky CH-54 cargo helicopter is named the "Tarhe" in honor of him. References External links "Tarhe: Grand Sachem" by C. A.

BLU-82
The BLU-82B/C-130 weapon system, known under program "Commando Vault" and nicknamed " Daisy Cutter" in Vietnam for its ability to flatten a section of forest into a helicopter landing zone, is an American conventional bomb, delivered from either a C-130 or MC-130 transport aircraft or a CH-54 heavy-lift "Skycrane" helicopter from the 1st Air Cavalry. A total of 225 were constructed. It was successfully used during military operations in Vietnam, the Gulf War and Afghanistan. The BLU-82 was retired in 2008 and replaced with the more powerful GBU-43/B MOAB. Overview The designation "BLU" stands for Bomb Live Unit, as opposed to "BDU" (Bomb Dummy Units) used for practice. Originally designed to create an instant clearing in the jungles of Vietnam, the BLU-82B/C-130 was test-dropped there from a CH-54 Tarhe "Flying crane" helicopter. Later it was used in Afghanistan as an anti-personnel weapon and as an intimidation weapon because of its very large blast radius (variously reporte ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

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 ...

Fly-by-wire
Fly-by-wire (FBW) is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires, and flight control computers determine how to move the actuators at each control surface to provide the ordered response. It can use mechanical flight control backup systems (like the Boeing 777) or use fully fly-by-wire controls.Fly by Wire Flight Control Systems Sutherland Improved fully fly-by-wire systems interpret the pilot's control inputs as a desired outcome and calculate the control surface positions required to achieve that outcome; this results in various combinations of rudder, elevator, aileron, flaps and engine controls in different ...

Aircraft Principal Axes
An aircraft in flight is free to rotate in three dimensions: '' yaw'', nose left or right about an axis running up and down; ''pitch'', nose up or down about an axis running from wing to wing; and ''roll'', rotation about an axis running from nose to tail. The axes are alternatively designated as ''vertical'', ''lateral'' (or ''transverse''), and ''longitudinal'' respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft. These definitions were analogously applied to spacecraft when the first manned spacecraft were designed in the late 1950s. These rotations are produced by torques (or moments) about the principal axes. On an aircraft, these are intentionally produced by means of moving control surfaces, which vary the distribution of the net aerodynamic force about the vehicle's center of gravity. Elevators (moving flaps on the horizontal tail) produce pitch, a rudder on the vertical tail produces yaw, and ailerons (flaps on the win ...

Instrument Flight Rules
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for n ...
