Data current to 5 May 2020.

Fort Rucker, U.S. Army Aviation Museum, Bldg 617, PO Box 620610, 36362-5134.  Tel: 334-255-4443.

Fort Rucker is a U.S. Army post located mostly in Dale County, Alabama, United States. It was named for a Civil War officer, Confederate General Edmund Rucker.  The post is the primary flight training base for Army Aviation and is home to the United States Army Aviation Center of Excellence (USAACE) and the United States Army Aviation Museum.  Small sections of the post also lie in Coffee, Geneva, and Houston counties.  Part of the Dale County section of the base is a census-designated place; its population was 4,636 at the 2010 census. The main post has entrances from three bordering cities, Daleville, Ozark and Enterprise.  In the years before the 11 September 2001 attacks, the main post (except airfields and other restricted areas) was an open post with unmanned gates allowing civilians to drive through.  Following the attacks, this policy was changed, and the post is now closed to unauthorized traffic and visitors.

The U.S. Army Aviation Center of Excellence is the dominant military facility at Fort Rucker. Training, doctrine, and testing are all key parts of the Center’s mission to develop Army Aviation’s capabilities. All Army Aviation training has been undertaken at Fort Rucker since 1973, as well as training of US Air Force and ally helicopter pilots. The Center is home to the US Army Aviation Technical Test Center (ATTC), which conducts developmental aircraft testing for Army Aviation.  The United States Army Operational Test and Evaluation Command’s Test and Evaluation Coordination Office and TH-67 primary and instrument training are both located at Cairns Army Airfield.

Operational units on the post include the 1st Aviation Brigade and the 110th Aviation Brigade handling Army Aviation training, and the USAF 23rd Flying Training Squadron for the training of Air Force helicopter pilots.

The 110th Aviation Brigade consists of five battalions using three different sites. 1st Battalion, 11th Aviation Regiment, operates and manages air traffic control services and flight simulation support for USAAVNC/Fort Rucker and the National Airspace System. 1st Battalion, 14th Aviation Regiment operates from Hanchey Army Heliport and conducts graduate level training using the AH-64D Apache Longbow and OH-58D Kiowa helicopters. 1st Battalion, 212th Aviation Regiment operates from Lowe Army Heliport and Shell Army Heliport and conducts combat and night operational training, using theOH-58, UH-1, and UH-60 helicopters. 1st Battalion, 223d Aviation Regiment operates from Cairns Army Airfield and Knox Army Heliport and conducts flight training using the CH-47 Chinook helicopter and C-12 Huron aircraft. The Helicopter School Battalion operates from Shell Army Heliport and, providing training for Latin American pilots under the United States Security Cooperation Program.

Boeing Vertol XCH-62A HLH (Serial No. 73-22012).  Prototype heavy-lift helicopter.  Scrapped.

The Boeing Vertol XCH-62 (Model 301) was a three turbine-engined, heavy-lift helicopter (HLH) project designed for the United States Army.  Designated XCH-62A, it appeared to be a scaled-up CH-47 without a conventional body, in a configuration similar to the S-64 Skycrane (CH-54 Tarhe).  Approved in 1971, only one aircraft was built before it was cancelled in 1974.  An attempt by NASA to resurrect the program and it was restarted for test flights in the 1980s, but was again not funded by Congress and the program was aborted in 1983.  The scaled up model of the HLH was scrapped at the end of 2005 at Fort Rucker, Alabama.

Following award of an Army contract for a prototype of a “Heavy Lift Helicopter (HLH)” in 1973, Boeing moved forward on building an oversized flying crane machine, the “XCH-62”.  Rotor diameter was to be 28 meters (92 ft), fuselage length 27.2 meters (89 feet 3 inches), and footprint length 49.5 meters (162 feet 3 inches).  Its widely-spaced landing gear would allow it to straddle heavy cargoes such as armored vehicles, and still carry twelve troops in its slender fuselage. Boeing also considered selling a commercial version, the “Model 301”.  The helicopter was powered by three Allison XT701-700 turboshafts, each rated at 8,079 shp, which fed into a combining gearbox capable of absorbing 17,700 shp.

The XCH-62 prototype was in an advanced state of assembly in 1975, being readied for a planned initial flight in 1976.  Failures in the spiral bevel gearing of the main transmission were experienced in tests because the method of analysis employed had not considered the effect of rim bending.  Consequently, new gears with strengthened rims were designed and fabricated. For a more accurate prediction of the load capacity of the gears, an extensive Finite Element Method (FEM) system was developed.  The U.S. Army’s XCH-62 HLH aft rotor transmission was finally successfully tested at full design torque and speed, but the US Congress cut funding for the program in August 1975.  The designers of the Mil Mi-26 avoided similar problems by using a split-torque design in the main rotor transmission.

The incomplete XCH-62 prototype (73-22012) was stored at the US Army Aviation Museum at Fort Rucker, Alabama.  It was to be pulled out of storage in the mid-1980s when the Army, the US National Aeronautics & Space Administration (NASA), and the Defense Advanced Research Projects Agency (DARPA) collaborated on a scheme to finish the XCH-62 for experimental flights, but Congress declined funding.  The XCH-62 prototype, the largest helicopter ever built in the western countries, was displayed at the US Army Aviation Museum until it was scrapped in 2005.  In 2008, several parts were sent to the Helicopter Museum at Weston-super-Mare (United Kingdom), to be exhibited there.
