Garrett AiResearch TPE331-1-101
The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was originally designed in the 1950s by Garrett AiResearch, and produced since 1999 by Honeywell Aerospace. The engine's power output ranges from . Design and development Garrett AiResearch designed the TPE331 from scratch in 1959 for the military. “Designed as a 575-horsepower engine it was not a scaled-down version of a larger engine, as competitors were offering.” The TPE331 originated in 1961 as a gas turbine (the "331") to power helicopters. It first went into production in 1963. More than 700 had been shipped by the end of 1973. It was designed to be both a turboshaft (TSE331) and a turboprop (TPE331), but the turboshaft version never went into production. The first engine was produced in 1963, installed on the Aero Commander in 1964 and put into production on the Aero Commander Turbo Commander in June 1965. Performance The 715 shp TPE331-6 used in the Beech King Air B100 have a 400-hr. f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Time Between Overhaul
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. On rotorcraft, many components have recommended or mandatory TBOs, including main rotor blades, tail rotor blades and gearboxes. For engines, the time between overhauls is generally a function of the complexity of the engine and how it is used. Piston-based engines are much more complex than turbine-powered engines, and generally have TBOs on the order of 1,200 to 2,000 hours of running time. They tend toward the lower number if they are new designs, or include boosting options such as a turbocharger. In comparison, jet engines and turboprop A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel ... ...

Testbed Aircraft
A testbed aircraft is an aeroplane, helicopter or other kind of aircraft intended for flight research or testing the aircraft concepts or on-board equipment. These could be specially designed or modified from serial production aircraft. Use of testbed aircraft For example, in development of new aircraft engines, these are fitted to a testbed aircraft for flight testing, before certification. For this adaptation it is required, among other changes, that new instrumentation wiring and equipment, fuel system and piping, as well as structural modifications of wing. The Folland Fo.108 (nicknamed the "Folland Frightful") was a dedicated engine testbed aircraft of the 1940s. The aircraft had a mid fuselage cabin for test instrumentation and observers. Twelve were built and provided to British aero-engine companies. A large number of aircraft-testbeds have been produced and tested since 1941 in the USSR and Russia by the Gromov Flight Research Institute. AlliedSignal, Honeywell Aerosp ...

Boeing 720
The Boeing 720 is an American narrow-body airliner produced by Boeing Commercial Airplanes. Announced in July 1957 as a 707 derivative for shorter flights from shorter runways, the 720 first flew on November 23, 1959. Its type certificate was issued on June 30, 1960, and it entered service with United Airlines on July 5, 1960. A total of 154 Boeing 720s and 720Bs were built until 1967. As a derivative, the 720 had low development costs, allowing profitability despite few sales. Compared to the 707-120, it has a length reduced by 8.33 feet (2.54 m), a modified wing and a lightened airframe for a lower maximum takeoff weight. Originally designed to be powered by four Pratt & Whitney JT3C turbojets, the initial 720 would cover a range with 131 passengers in two classes. The reconfigured 720B, powered by JT3D turbofans, first flew on October 6, 1960, and entered service in March 1961. It could seat 156 passengers in one class over a range. Some 720s were later converted to 720 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embraer/FMA CBA 123 Vector
The Embraer/FMA CBA 123 Vector (originally EMB 123 for Embraer and IA 70 for FMA) was a 1990 turboprop aircraft designed for regional flights, to carry up to 19 passengers. The program arose from a partnership between the Brazilian company Embraer and the Argentine FMA. The project was an advanced turboprop aircraft for its time, including advanced technology in avionics, aerodynamics, and propulsion. * Development By 1985, economic integration of South America seemed to be in progress with advances in the negotiations of Mercosur between the Brazilian and Argentine governments. Meanwhile, in 1985, the Brazilian aircraft manufacturer Embraer, having commenced production of its EMB 120 Brasilia 30-seat turboprop airliner, started the design process for a 19-seat airliner to replace Embraer's aging EMB 110 Bandeirante. In 1986, as a way of encouraging partnership between both countries, an agreement to develop a Brazilian-Argentine aircraft was signed between Embraer and the Arg ...

TPF351
The Garrett TPF351 is a turboprop engine designed by Garrett Engine Division of AlliedSignal Aerospace Company. Initiated by Garrett in October 1987, the TPF351-20 engine was selected by Embraer to power the Embraer/FMA CBA 123 Vector, a high-speed commuter "pusher" aircraft. It was first tested on May 19, 1989 and then ground tested and flight tested on a Boeing 720 on July 9, 1990. The first prototype CBA 123 was tested on July 18, 1990, followed by a flight to the Farnborough Air Show in September of the same year. Both programs were cancelled in 1992, when the TPF351 was nine months from engine certification. Design It was built on the TPE331-14 which power the Jetstream 41, keeping its combustor system and high pressure turbine, already of the right size. The two-stage centrifugal compressor is scaled-up from the Garrett F109 turbofan of the Fairchild T-46 and Promavia Jet Squalus trainers. The engine ran about hotter than the TPE331-14 in the core. It was Garrett's fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-55
The Sikorsky H-19 Chickasaw (company model number S-55) was a multi-purpose helicopter used by the United States Army and United States Air Force. It was also license-built by Westland Aircraft as the Westland Whirlwind in the United Kingdom. United States Navy and United States Coast Guard models were designated HO4S, while those of the U.S. Marine Corps were designated HRS. In 1962, the U.S. Navy, U.S. Coast Guard and U.S. Marine Corps versions were all redesignated as H-19s like their U.S. Army and U.S. Air Force counterparts. Development Development of the H-19 was initiated privately by Sikorsky without government sponsorship. The helicopter was initially designed as a testbed for several novel design concepts intended to provide greater load-carrying ability in combination with easy maintenance. Under the leadership of designer Edward F. Katzenberger, a mockup was designed and fabricated in less than one year. The first customer was the United States Air Force, which o ...

Regional Airliner
A regional airliner or a feederliner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feederliner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines: even the De Havilland Dragon Rapide biplane, or the Douglas DC-3s, in large surplus after the war, which the Aircraft manufacturers wanted t ...

Trainer Aircraft
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shorts Tucano
The Short Tucano is a two-seat turboprop basic trainer built by Short Brothers in Belfast, Northern Ireland. It is a licence-built version of the Brazilian Embraer EMB 312 Tucano. On 14 February 1986, the prototype conducted its maiden flight in Brazil before being delivered to Shorts to be used as a pattern aircraft and modified to meet Royal Air Force (RAF) requirements and used for trials and demonstrations. The first Short-assembled aircraft flew on 30 December 1986; deliveries to the RAF commenced during June 1988. The final example of the type was completed in 1995. Maintenance and support of the RAF's Tucano fleet was typically outsourced to several private companies. The RAF was the Tucano's primary operator, although export sales have been achieved with the nations of Kenya and Kuwait. A handful have also been purchased and piloted by private individuals. On 25 October 2019, the Tucano was withdrawn from RAF service and was replaced by the Beechcraft T-6Cs. Design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cessna Conquest
The Cessna 441 Conquest II is the first turboprop powered aircraft designed by Cessna, and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8–9 passenger turbine development of the Cessna 404 Titan. Development The original design from 1972 for this aircraft was known as the Model 435, and was to be powered by Continental GTSIO-520X engines with three-bladed propellers. By 1975, the designed evolved into the turboprop-powered Model 441. It was certified by the FAA on August 19, 1977. Cessna renamed the Model 441 the Conquest II in 1983. 1984 models starting with constructor number 195 used lighter weight four-bladed McCauley propellers. Phillips, Edward H.: ''Wings of Cessna, Model 120 to the Citation III'', Flying Books, 1986. A 441 with Pratt & Whitney Canada PT6A-112 turboprops was flown in 1986, but did not enter production.

Beechcraft King Air
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). The King Air was the first aircraft in its class and was produced continuously from 1964 to 2021. It outsold all of its turboprop competitors combined. It has recently faced competition from jet aircraft such as the Embraer Phenom 100, Honda HA-420 HondaJet and Cessna Citation Mustang; as well as from newer turboprop aircraft including the Piaggio P180 Avanti, and single-engine Piper Malibu Meridian, Pilatus PC-12, and Socata TBM.
