The Fairchild Republic A-10-C Warthog The Thunderbolt II is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). Commonly referred to by its nicknames Warthog or Hog, its official name comes from the Republic P-47 Thunderbolt, a World War II fighter that was effective at attacking ground targets. The A-10 was designed for close-in support of ground troops, close air support (CAS), and providing quick-action support for troops against helicopters and ground forces. It entered service in 1976 and is the only production-built aircraft that has served in the USAF that was designed solely for CAS. Its secondary mission is to provide forward air controller – airborne (FAC-A) support, by directing other aircraft in attacks on ground targets. Aircraft used primarily in this role are designated OA-10.
The A-10 was intended to improve on the performance of the A-1 Skyraider and its poor firepower. The A-10 was designed around the 30 mm GAU-8 Avenger rotary cannon. Its airframe was designed for durability, with measures such as 1,200 pounds (540 kg) of titanium armor to protect the cockpit and aircraft systems, enabling it to absorb a significant amount of damage and continue flying. Its short takeoff and landing capability permits operation from airstrips close to the front lines, and its simple design enables maintenance with minimal facilities. The A-10 served in Operation Desert Shield, and Operation Desert Storm, the American intervention against Iraq's invasion of Kuwait, where the A-10 distinguished itself. The A-10 also participated in other conflicts such as Operation Urgent Fury in Grenada, the Balkans, Afghanistan, Iraq, and against ISIL in the Middle East.
The A-10A single-seat variant was the only version produced, though one pre-production airframe was modified into the YA-10B twin-seat prototype to test an all-weather night capable version. In 2005, a program was started to upgrade remaining A-10A aircraft to the A-10C configuration with modern avionics for use of precision weaponry. The U.S. Air Force had stated the F-35 would replace the A-10 as it entered service, but this remains highly contentious within the Air Force and in political circles. With a variety of upgrades and wing replacements, the A-10's service life may be extended to 2040.
The Sikorsky MH-60G/HH-60G Pave Hawk is a twin turboshaft engine helicopter in service with the United States Air Force. It is a derivative of the UH-60 Black Hawk and incorporates the US Air Force PAVE electronic systems program. The HH-60/MH-60 is a member of the Sikorsky S-70 family.
The MH-60G Pave Hawk's primary mission is insertion and recovery of special operations personnel, while the HH-60G Pave Hawk's core mission is recovery of personnel under stressful conditions, including search and rescue. Both versions conduct day or night operations into hostile environments. Because of its versatility, the HH-60G may also perform peace-time operations such as civil search and rescue, emergency aeromedical evacuation (MEDEVAC), disaster relief, international aid and counter-drug activities.

General Dynamics AGM-109 Air-launched Cruise Missile
In 1977, the Carter Administration initiated the Joint Cruise Missile Project, which instructed the Air Force and Navy to develop their cruise missiles using common technology. The Air Force was already developing the AGM-86 air-launched cruise missile (ALCM) and the Navy was working on the BGM-109 sea-launched cruise missile (SLCM), with plans for an air-launched version. After flight testing, conducted between July 1979 and February 1980, the AGM-86 was declared the winner of the ALCM competition and the development of the AGM-109 contender ended.
This AGM-109 test body was created for static testing and weight and balance tests conducted during the ALCM competition. The Ogden Air Logistics Center at Hill AFB was assigned repair and testing responsibilities for the ALCM in November 1979. Much of the ALCM competition took place here and on the nearby Utah Test and Training Range.

Note the unique "1.5-Stage" fan on this first-generation turbofan. GE designed the first "half-stage" fan to supercharge another full-stage fan behind it. The runner on the edge of the picture is held in place by a set of inlet guide vanes, which, combined with the short fan cowl and early lip design, account for the shrill whine of the TF39-1C that distinguishes a C-5 from miles away. These design features are unique to the TF39; the CF6 has one large fan and a fatter nacelle.

The technology in modern commercial turbofans not only has made them remarkably efficient in terms of fuel burn but also superbly reliable. Back on June 2012 a CFM56-7B engine on a Boeing 737-800 operated by European operator TUIfly became the first jet engine to reach 50,000 hours on the wing without a shop visit.
The Rolls-Royce Pegasus, formerly the Bristol Siddeley Pegasus, is a British turbofan engine originally designed by Bristol Siddeley and was manufactured by Rolls-Royce Limited. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. Lightly loaded aircraft equipped with this engine can manoeuvre like a Helicopter. In particular, they can perform vertical takeoffs and landings. In U.S service, the engine is designated F402.
The unique Pegasus engine powers all versions of the Harrier family of Multi-Role Military Aircraft. Rolls-Royce licensed Pratt & Whitney to build the Pegasus for U.S built versions. However Pratt & Whitney never completed any engines, with all new build being manufactured by Rolls-Royce in Bristol, England. The Pegasus was also the planned engine for a number of aircraft projects, among which were the prototypes of the German Dornier Do 31 VSTOL Military Transport project.
Michel Wibault, the French aircraft designer, had the idea to use vectored thrust for Vertical Take-Off Aircraft. This thrust would come from four centrifugal blowers shaft driven by a Bristol Orion turboprop, the exhaust from each blower being vectored by rotating the blower scrolls. Although the idea of vectoring the thrust was quite novel, the engine proposed was considered to be far too heavy.
As a result, an engineer at Bristol Engine Company, Gordon Lewis, began in 1956 to study alternative engine concepts, using, where possible, existing engine components from the Orpheus and Olympus engine series. The work was overseen by the Technical Director Stanley Hooker. One concept which looked promising was the BE52, which initially used the Orpheus 3 as the engine core and, on a separate coaxial shaft, the first two stages of an Olympus 21 LP compressor, which acted as a fan, delivering compressed air to two thrust vectoring nozzles at the front of engine. At this point in the design exercise, the exhaust from the LP turbine discharged through a conventional rear nozzle. There were separate intakes for the fan and core compressor because the fan did not supercharge the core compressor. Although the BE.52 was a self-contained powerplant and lighter than Wibault's concept, the BE.52 was still complicated and heavy. As a result, work on the BE.53 concept started in February 1957. In the BE.53 the Olympus stages were fitted close to the Orpheus stages, thus simplifying the inlet ducting. The Olympus stages now supercharged the Orpheus core, improving the overall pressure ratio, creating what is now considered a conventional turbofan configuration.
For a year Bristol designed the engine in isolation, with little feedback from the various airframe manufacturers furnished with data. However, in May 1957 the team received a supportive letter from Sydney Camm of Hawker Aviation stating they were looking for a Hawker Hunter replacement. The aircraft designer, Ralph Hooper, suggested having the four thrust vectoring nozzles (originally suggested by Lewis) with hot gases from the rear two. Further joint discussions helped to refine the engine design.
The 1957 Defence White Paper, which focused on Missiles, and not Manned Aircraft (which were declared 'obsolete') was not good news, because it precluded any future government financial support for development of not already extant manned Combat Aircraft. This prevented any official financial support for the engine or aircraft from the Ministry of Defence. Fortunately, engine development was financially supported to the tune of 75% from the Mutual Weapons Development Program, Verdon Smith of Bristol Siddeley Engines Limited (BSEL) which Bristol Engines had by then become on its merger with Armstrong Siddeley, quickly agreeing to pay the remainder.
The first prototype engine (one of two BE53/2's built) ran on 2nd September 1959 and featured a 2-stage fan and used the Orpheus 6 core. Although the fan was overhung, inlet guide vanes were still incorporated. The HP spool comprised a 7-stage compressor driven by a single stage turbine. A 2-stage LP turbine drove the fan. There was no plenum at fan exit, but 4 thrust vectoring nozzles were fitted. Further development of the engine then proceeded in tandem with the aircraft, the Hawker P.1127. The aircraft first flew (tethered hover) on 21st October 1960, powered by the BE53/3 (Pegasus 2). Free hover was achieved on 19th November of the same year. Transition to wing-borne flight occurred in 1961. Later versions of the P.1127 were fitted with the Pegasus 3 and eventually the Pegasus 5. The Pegasus 5 was also used in the Kestrel, a refinement of the P.1127, of which nine were built for a Tripartite evaluation exercise. The Kestrel was subsequently developed into the Harrier Combat Aircraft. By the time the Pegasus 5/2 was built, both the fan and HP compressor had been zero-staged and 2nd stage added to the HP turbine.

The Fairchild Republic A-10-C Warthog The Thunderbolt II is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). Commonly referred to by its nicknames Warthog or Hog, its official name comes from the Republic P-47 Thunderbolt, a World War II fighter that was effective at attacking ground targets. The A-10 was designed for close-in support of ground troops, close air support (CAS), and providing quick-action support for troops against helicopters and ground forces. It entered service in 1976 and is the only production-built aircraft that has served in the USAF that was designed solely for CAS. Its secondary mission is to provide forward air controller – airborne (FAC-A) support, by directing other aircraft in attacks on ground targets. Aircraft used primarily in this role are designated OA-10.
The A-10 was intended to improve on the performance of the A-1 Skyraider and its poor firepower. The A-10 was designed around the 30 mm GAU-8 Avenger rotary cannon. Its airframe was designed for durability, with measures such as 1,200 pounds (540 kg) of titanium armor to protect the cockpit and aircraft systems, enabling it to absorb a significant amount of damage and continue flying. Its short takeoff and landing capability permits operation from airstrips close to the front lines, and its simple design enables maintenance with minimal facilities. The A-10 served in Operation Desert Shield, and Operation Desert Storm, the American intervention against Iraq's invasion of Kuwait, where the A-10 distinguished itself. The A-10 also participated in other conflicts such as Operation Urgent Fury in Grenada, the Balkans, Afghanistan, Iraq, and against ISIL in the Middle East.
The A-10A single-seat variant was the only version produced, though one pre-production airframe was modified into the YA-10B twin-seat prototype to test an all-weather night capable version. In 2005, a program was started to upgrade remaining A-10A aircraft to the A-10C configuration with modern avionics for use of precision weaponry. The U.S. Air Force had stated the F-35 would replace the A-10 as it entered service, but this remains highly contentious within the Air Force and in political circles. With a variety of upgrades and wing replacements, the A-10's service life may be extended to 2040.

The MH-60G Pave Hawk's primary mission is insertion and recovery of special operations personnel, while the HH-60G Pave Hawk's core mission is recovery of personnel under stressful conditions, including search and rescue. Both versions conduct day or night operations into hostile environments. Because of its versatility, the HH-60G may also perform peace-time operations such as civil search and rescue, emergency aeromedical evacuation (MEDEVAC), disaster relief, international aid and counter-drug activities.
