Development

The F101 was developed specifically for the Advanced Manned Strategic Aircraft, which became the B-1A. The F101 powered the four development aircraft from 1970 to 1981. The B-1A was officially cancelled in 1977. However the flight test program continued. General Electric was awarded a contract to further develop the F101-102 engine variant. This turbofan eventually powered the B-1B from 1984, entering service in 1986. The B-1's four F101 engines helped the aircraft win 61 world records for speed, payload and range.

The GE F110 fighter engine is a derivative of the F101, designed using data from the F101-powered variant of the F-16 Fighting Falcon tested in the early 1980s. The F101 also became the basis for the highly successful CFM56 series of civil turbofans.

410th Flight Test Squadron

The 410th Flight Test Squadron is an inactive United States Air Force squadron. It was last assigned to the 412th Operations Group at Air Force Plant 42, Palmdale Regional Airport, California, where it was inactivated on 1 August 2008. The squadron's primary mission throughout its lifetime was flight and acceptance testing of the Lockheed F-117A Nighthawk stealth fighter and the Rockwell B-1B Lancer bomber. Activated in March 1989 for B-1B flight testing, the mission of the unit was changed in 1993 when B-1 testing transferred to the 419th Flight Test Squadron and the squadron became the F-117A test squadron, assuming the mission originated in 1980 at Groom Lake, Nevada.

Arnold Air Force Base

Arnold Air Force Base (Arnold AFB) (ICAO: KAYX, FAA LID: AYX) is a United States Air Force base located in Coffee and Franklin counties, Tennessee, adjacent to the city of Tullahoma. It is named for General Henry "Hap" Arnold, the father of the U.S. Air Force.

There is no longer an active airfield on the base, as the airfield was decommissioned in 2009. Army aviation assets (helicopters) continue to utilize Arnold as part of missions supporting Fort Campbell, Kentucky or the Tennessee Army National Guard.

The base is home to the Arnold Engineering Development Complex (AEDC), the most advanced and largest complex of flight simulation test facilities in the world. The center operates 58 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized units. AEDC is an Air Force Test Center organization.The commander of Arnold Engineering Development Center is Col. Scott A. Cain. and Mark A. Mehalic is the Executive Director,.

CFM International CFM56

The CFM International CFM56 (U.S. military designation F108) series is a family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,500 to 34,000 pounds-force (82 to 150 kilonewtons). CFMI is a 50–50 joint-owned company of Safran Aircraft Engines (formerly known as Snecma) of France, and GE Aviation (GE) of the United States. Both companies are responsible for producing components and each has its own final assembly line. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Snecma manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy. The engines are assembled by GE in Evendale, Ohio, and by Snecma in Villaroche, France. The completed engines are marketed by CFMI. Despite initial export restrictions, it is one of the most common turbofan aircraft engines in the world, in four major variants.

The CFM56 first ran in 1974. In April 1979, the joint venture had not received a single order in five years and was two weeks away from being dissolved. The program was saved when Delta Air Lines, United Airlines, and Flying Tigers chose the CFM56 to re-engine their DC-8s and shortly thereafter it was chosen to re-engine the KC-135 Stratotanker fleet of the U.S. Air Force – still its biggest customer. The first engines entered service in 1982. Several fan blade failure incidents were experienced during the CFM56's early service, including one failure that was a cause of the Kegworth air disaster, and some engine variants experienced problems caused by flight through rain and hail. Both these issues were resolved with engine modifications.

General Dynamics F-111 Aardvark

The General Dynamics F-111 Aardvark was a supersonic, medium-range interdictor and tactical attack aircraft that also filled the roles of strategic nuclear bomber, aerial reconnaissance, and electronic-warfare aircraft in its various versions. Developed in the 1960s by General Dynamics, it first entered service in 1967 with the United States Air Force. The Royal Australian Air Force (RAAF) also ordered the type and began operating F-111Cs in 1973.

The F-111 pioneered several technologies for production aircraft, including variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. Its design influenced later variable-sweep wing aircraft, and some of its advanced features have since become commonplace. The F-111 suffered a variety of problems during initial development. Several of its intended roles, such as an aircraft carrier-based naval interceptor with the F-111B, failed to materialize.

USAF F-111 variants were retired in the 1990s, with the F-111Fs in 1996 and EF-111s in 1998. The F-111 was replaced in USAF service by the F-15E Strike Eagle for medium-range precision strike missions, while the supersonic bomber role has been assumed by the B-1B Lancer. The RAAF was the last operator of the F-111, with its aircraft serving until December 2010.

Launched in May 2017 to power the Aerion AS2 supersonic business jet, its initial design was completed in 2018 before its detailed design in 2020 for the first prototype production.

Its high-pressure core is derived from the CFM56, matched to a new twin fan low-pressure section for a reduced bypass ratio better suited to supersonic flight.

General Electric Everett Plant

General Electric Everett Plant, formerly known as Air Force Plant 28, was a plant operated by General Electric from 1941 into the 1980s in Everett, Massachusetts. It was situated along the Malden River on a forty-three acre tract, covering 344,342 square feet. The facility, before it was demolished, was the location of ten smaller buildings and one large manufacturing facility. At the time, it was also home to machining, metal stamping, welding, grinding, cleaning and parts testing. Previously, the plant also was home to metal plating. The plant was closed after General Electric decided to consolidate manufacturing at other plants across the country, including to that in nearby Lynn, where parts from Everett were assembled into engines.

General Electric F110

The General Electric F110 is an afterburning turbofan jet engine produced by GE Aviation. The F110 engine uses the same engine core design as the General Electric F101. The F118 is a non-afterburning variant. The engine is also license-built in Eskisehir, Turkey by TUSAŞ Engine Industries (TEI).

Kuznetsov NK-32

The Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It is the largest and most powerful engine ever fitted on a combat aircraft. It produces 245 kN (55,000 lbf) of thrust in maximum afterburner.

A non-afterburning variant known as NK-32 Tier 2 for Tu-160 and NK-65 will be used in the upcoming Russian bomber, PAK DA.NK-65 and a geared high-bypass turbofan variant PD-30, with a thrust of 30 tonnes (around 300 kN) has been proposed for use on new Russian wide-body airliners, as well as the upgraded Antonov An-124 Ruslan heavylifter.

Laser peening

Laser peening (LP), or laser shock peening (LSP), is a surface engineering process used to impart beneficial residual stresses in materials. The deep, high magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The physics of the laser shock peening process can also be used to strengthen thin sections, work-harden surfaces, shape or straighten parts (known as laser peen forming), break up hard materials, compact powdered metals and for other applications where high pressure, short duration shock waves offer desirable processing results.

Rockwell B-1 Lancer

The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It is commonly called the "Bone" (from "B-One"). It is one of three strategic bombers in the U.S. Air Force fleet as of 2018, the other two being the B-2 Spirit and the B-52 Stratofortress.

The B-1 was first envisioned in the 1960s as a platform that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, and would ultimately replace both bombers. After a long series of studies, Rockwell International (now part of Boeing) won the design contest for what emerged as the B-1A. This version had a top speed of Mach 2.2 at high altitude and the capability of flying for long distances at Mach 0.85 at very low altitudes. The combination of the high cost of the aircraft, the introduction of the AGM-86 cruise missile that flew the same basic profile, and early work on the stealth bomber all significantly affected the need for the B-1. This led to the program being canceled in 1977, after the B-1A prototypes had been built.

The program was restarted in 1981, largely as an interim measure until the stealth bomber entered service. This led to a redesign as the B-1B, which had lower top speed at high altitude of Mach 1.25, but improved low-altitude performance of Mach 0.96. The electronics were also extensively improved during the redesign, and the airframe was improved to allow takeoff with the maximum possible fuel and weapons load. The B-1B began deliveries in 1986 and formally entered service with Strategic Air Command (SAC) as a nuclear bomber in 1986. By 1988, all 100 aircraft had been delivered.

In the early 1990s, following the Gulf War and concurrent with the disestablishment of SAC and its reassignment to the newly formed Air Combat Command, the B-1B was converted to conventional bombing use. It first served in combat during Operation Desert Fox in 1998 and again during the NATO action in Kosovo the following year. The B-1B has supported U.S. and NATO military forces in Afghanistan and Iraq. The Air Force had 66 B-1Bs in service as of September 2012. The B-1B is expected to continue to serve into the 2030s, with the Northrop Grumman B-21 Raider to begin replacing the B-1B after 2025. The B-1s currently in inventory will be retired by 2036.
