Pratt & Whitney: Ғасырлық авиация тарихы мен қазіргі кезеңі

Aircraft engine manufacturer

In April 1925, Frederick Rentschler, an Ohio native and former executive at Wright Aeronautical, was determined to start an aviation related business of his own. His social network included Edward Deeds, another prominent Ohioan of the early aviation industry, and Frederick's brother Gordon Rentschler, both of whom were on the board of Niles Bement Pond, then one of the largest machine tool corporations in the world. Frederick Rentschler approached these men as he sought capital and assets for his new venture. Deeds and G. Rentschler persuaded the board of Niles Bement Pond that their Pratt & Whitney Machine Tool (P&WMT) subsidiary of Hartford, Connecticut, should provide the funding and location to build a new aircraft engine being developed by Rentschler, George J. Mead, and colleagues, all formerly of Wright Aeronautical. Eventually a whole Wasp series was developed. Both engines are still in use in agricultural aircraft around the world and produce more power than their original design criteria. George Mead soon led the next step in the field of large, state of the art, air cooled, radial aircraft engines (which the Wasp dominated) when Pratt & Whitney released its R 1690 Hornet. It was basically "a bigger Wasp". In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool and merged Pratt & Whitney Aircraft with Boeing and other companies to form the United Aircraft and Transport Corporation (UATC). His agreement allowed him to carry the Pratt & Whitney name with him to his new corporation. Only five years later, in 1934, the federal government of U. S. banned common ownership of airplane manufacturers and airlines. Pratt & Whitney was merged with UATC's other manufacturing interests east of the Mississippi River as United Aircraft Corporation, with Rentschler as president. In 1975, United Aircraft Corporation became United Technologies.

In October 2014, Pratt & Whitney was awarded a $592 million contract with Department of Defense (DoD) to supply 36 F135 engines for the F 35 fighter. In January 2017, ten employees, including the head of the F135 engine program, reportedly left the company after expenses incurred to transport South Korean officials to the company's West Palm Beach, Florida facility in 2012 were deemed unethical. In 2020, United Technologies merged with Raytheon Company to form Raytheon Technologies, with Pratt & Whitney becoming one of the new corporation's four main subsidiaries. In November 2022, Pratt & Whitney was awarded a contract for nearly $4.4 billion by the US DoD to build 100 jet engines for the U. S. military's Air Force, Navy, and Marine Corps branches. As of May 2023, Pratt & Whitney was "struggling to support its fleet of passenger jets with enough spare parts and engines" which had consequences for airlines worldwide who had to ground their Airbus A320 Neo and Airbus A220. The durability of the Pratt & Whitney PW1000G geared turbofan engine since its inception in 2016 has been the central issue. In July 2023, Pratt & Whitney issued a product recall that would affect hundreds of jet engines. The recall was issued due to a concern of metal parts being contaminated that could lead to cracking over time. as of September 2023, it was estimated that around 3,000 engines might have been manufactured with flawed components.

Pratt & Whitney is headquartered in East Hartford, Connecticut and also has plants in Londonderry, New Hampshire; Springdale, Arkansas; Columbus, Georgia; Middletown, Connecticut; Middletown, Pennsylvania; Dallas, Texas; Palm Beach County, Florida; North Berwick, Maine; Aguadilla, Puerto Rico; Asheville, North Carolina and Bridgeport, West Virginia. Pratt & Whitney holds the naming rights for the home stadium for the University of Connecticut Huskies football team, Rentschler Field, which is located adjacent to Pratt & Whitney's East Hartford, Connecticut campus, on Pratt's company owned former airfield of the same name. In 2015, the stadium was renamed to Pratt & Whitney Stadium at Rentschler Field in time for the 2015–2016 University of Connecticut football season.

Pratt & Whitney is a business unit of aerospace conglomerate Raytheon Technologies, making it a sister company to Collins Aerospace, Raytheon Missiles & Defense and Raytheon Intelligence & Space. It is also involved in two major joint ventures, the Engine Alliance with GE which manufactures engines for the Airbus A380, and International Aero Engines company with Rolls Royce, MTU Aero Engines, and the Japanese Aero Engines Corporation which manufactures engines for the Airbus A320 and the McDonnell Douglas MD 90 aircraft.

Pratt & Whitney's large commercial engines power more than 25 percent of the world's passenger aircraft fleet and serve more than 800 customers in 160 countries. With more than 16,000 large commercial engines installed today, Pratt & Whitney provides power to hundreds of airlines and operators, from narrow bodied airplanes to wide bodied jumbo jetliners. In June 2007, Pratt & Whitney's fleet of large commercial engines surpassed 1 billion flight hours of service.

Pratt & Whitney's Global Material Solutions (GMS) makes parts for the CFM56 engine thus giving customers an alternative in new CFM56 engine materials. In addition to engine parts, GMS provides customers with fleet management and customized maintenance service programs. United Airlines was the GMS launch customer. GMS received its first part certification in July 2007, when the Federal Aviation Administration (FAA) granted Parts Manufacturing Approval (PMA) certification for the GMS high pressure turbine (HPT) shroud for the CFM56 3 engine. In March 2008, the FAA certified the GMS fan and booster with a Supplemental Type Certificate (STC) with FAA Chapter 5 life limits equal to the original type certificate holder. The STC was the first FAA certification ever granted for alternative life limited engine parts. In May 2008, Global Material Solutions received FAA STCs for its remaining life limited parts for CFM56 3 engines.

Pratt & Whitney Global Service Partners (GSP) offers overhaul, maintenance and repair services for Pratt & Whitney, International Aero Engines, General Electric, Rolls Royce, and CFMI engines. In addition to engine overhaul and repair services, GSP provides services including line maintenance, engine monitoring and diagnostics, environmentally friendly on wing water washes, leased engines, custom engine service programs and new and repaired parts. Pratt & Whitney maintains one of the largest service center networks in the world, with more than 40 engine overhaul and maintenance centers located around the globe. The Global Service Partners includes Japan Turbine Technologies (JTT). JTT started in 2000 as a joint venture between Pratt and Japan Airlines, with Japan Airlines owning 33.4 percent of the venture, and Pratt & Whitney owning the rest. In July 2011 Pratt bought out Japan Airlines' share in the venture. The facility is located in the town of Taiei near the city of Narita in the Chiba Prefecture and it primarily repairs V2500, JT8D engine parts.

Pratt & Whitney's Military Engines power 27 air forces around the globe, with nearly 11,000 military engines in service with 23 customers in 22 nations. Pratt & Whitney military engines include the F135 for the F 35 Lightning II, the F119 for the F 22 Raptor, the F100 family that powers the F 15 Eagle and F 16 Falcon, the F117 for the C 17 Globemaster III, the J52 for the EA 6B Prowler, the TF33 powering E 3 AWACS, E 8 Joint STARS, B 52, and KC 135 aircraft, and the TF30 for the F 111 and F 14A. In addition, Pratt & Whitney offers a global network of maintenance, repair, and overhaul facilities and military aviation service centers focused on maintaining engine readiness for their customers.

Pratt & Whitney Canada (PWC), originally Canadian Pratt & Whitney Aircraft Company, and later United Aircraft of Canada, provides a large range of products, including turbofan, turboprop and turboshaft engines targeted for the regional, business, utility and military aircraft and helicopter markets. The company also designs and manufactures engines for auxiliary power units and industrial applications. Its headquarters are located in Longueuil, Quebec (just outside Montreal). Speaking to Reuters June 16, 2013, ahead of the Paris Airshow 2013, Pratt & Whitney President David Hess said he was confident that Canada would decide to stick with the F 35 program despite its recent discussions about having a new competition. If the orders did shift to another company, Pratt & Whitney could decide to move some of the industrial base work it is currently doing in Canada, Hess said. "We might reallocate the work elsewhere", he said, adding that reduced order volumes would likely trigger changes in Canada. The division admitted in July 2012 to providing engines and engine software for China's first attack helicopter, the Z 10. This violated U. S. export laws and resulted in a multimillion dollar fine.

Pratt & Whitney Space Propulsion consisted of liquid space propulsion at the Liquid Space Propulsion Division (West Palm Beach, Florida) and solid rocket propulsion at the Chemical Systems Division (San Jose, California), as well as refurbishment and integration of the non motor elements of the Space Shuttle's solid rocket boosters at the USBI Co. Division (NASA Kennedy Space Center, Florida). Pratt & Whitney Space Propulsion provided advanced technology solutions to commercial, government and military customers for more than four decades. Products included the RL10, the upper stage rocket engine used on the Boeing Delta and Lockheed Martin Atlas rockets, high pressure turbopumps for the Space Shuttle Main Engines (SSME) and the RD 180 booster engine, offered by RD Amross, a partnership between Pratt & Whitney and NPO Energomash of Russia, for the Atlas III and V programs. The West Palm Beach site consisted of an engineering division and manufacturing division which designed and manufactured the high pressure turbopumps (fuel and LOX) for the Space Shuttle's Main Engines (SSME) which were manufactured by the former Rocketdyne Corporation.

Pratt & Whitney Rocketdyne (PWR) was formed in 2005 when Pratt & Whitney Space Propulsion and Rocketdyne Propulsion & Power were merged following the latter's acquisition from Boeing. P&W Rocketdyne engines powered the Space Shuttle, and the company also supplies booster engines for Delta II rockets and boosters and upper stage engines for Atlas III and V and Delta IV rockets. In 2013, PWR was sold to GenCorp, which merged it with Aerojet to become Aerojet Rocketdyne.

Pratt & Whitney Power Systems (PWPS) designs, builds, furnishes and supports aero derivative gas turbine and geothermal power systems for customers worldwide. These industrial gas turbines power everything from small businesses to small cities. PWPS’ industrial turbines not only generate electrical power, but provide variable speed mechanical drive for marine propulsion, gas compression, and liquid pumping. PWPS has over 2,000 industrial gas turbines installed in more than 40 countries worldwide. PWPS also provides parts and repairs for heavy duty frame gas turbines as an OEM alternative. In May 2013, United Technologies Corporation (UTC) sold its Pratt & Whitney Power Systems unit to Mitsubishi Heavy Industries (MHI).

International Aero Engines is a joint venture that develops, builds and services the V2500 aero engine family, which powers the Airbus A320 family and McDonnell Douglas MD 90 aircraft. The four founding engine manufacturers that make up IAE each contribute an individual module to the V2500 engine. Pratt & Whitney produces the combustor and high pressure turbine, Rolls Royce the high pressure compressor, JAEC the fan and low pressure compressor and MTU the low pressure turbine.

Engine Alliance, a 50/50 joint venture between General Electric and Pratt & Whitney, was formed in August 1996 to develop, manufacture, and support a family of modern technology engines for new high capacity, long range aircraft. The main application is the GP7200, which has been designed for use on the Airbus A380. It competes with the Rolls Royce Trent 900, the launch engine for the aircraft. The first GP7200 powered Airbus A380 entered service with Emirates on August 1, 2008, on a non stop flight from Dubai to New York City.

Between 1967 and 1971, Pratt & Whitney turbine engines were used in American Championship Car Racing and Formula One. The STP Paxton Turbocar dominated the 1967 Indianapolis 500 until a transmission bearing failed four laps from the finish. STP entered four Lotus 56s in the 1968 Indianapolis 500. One car crashed during qualifying. Two of the remaining cars qualified fastest and second fastest, but all three retired from the race. Turbine cars were deemed illegal before the following year's race, so Lotus chief Colin Chapman developed the car for use in Formula One and an updated 56B competed in half a dozen Formula One races in 1971.

Pratt & Whitney now markets its Ecopower pressure washing service, which uses a high pressure water spray run through several nozzles to clean grime and contaminants from jet engine parts, most notably turbine blades, to prevent overheating, improve engine operating efficiency and reduce fuel burn. The system collects the runoff from the washing process for appropriate disposal. The washing is accomplished at the airport tarmac in about one hour. Customers include United Airlines, Air India, Martinair, Thai Airways International, Virgin Atlantic, and JetBlue.
