HTT-40
The HAL HTT-40 (Hindustan Turbo Trainer-40) is an Indian training aircraft designed and built by Hindustan Aeronautics Limited (HAL). It will replace the Indian Air Force's retired HPT-32 Deepak as a basic trainer. Design and development The HTT-40 is an all-metal, tandem seat aircraft powered by a turboprop engine. In early 2012 the company forecast building 106 examples. By the middle of 2012 the aircraft's future was in doubt as the Indian Air Force ordered 75 Pilatus PC-7 Mk IIs to fill the role envisioned for the HTT-40. In September 2012 the Air Force indicated that it had formally rejected the HTT-40 for service based on its cost per aircraft being double that of the PC-7 Mk II, a proven aircraft, already in service worldwide. An MoD official noted, "We would be willing to pay higher rates to build indigenous capability in strategic defence equipment. But can HAL argue that the capability to build basic trainers is strategically vital At that time HAL did not co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Air Force
The Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its complement of personnel and aircraft assets ranks third amongst the air forces of the world. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflict. It was officially established on 8 October 1932 as an auxiliary air force of the British Empire which honoured India's aviation service during World War II with the prefix ''Royal''. After India gained independence from United Kingdom in 1947, the name Royal Indian Air Force was kept and served in the name of Dominion of India. With the government's transition to a Republic in 1950, the prefix ''Royal'' was removed. Since 1950, the IAF has been involved in four wars with neighbouring Pakistan. Other major operations undertaken by the IAF include Operation Vijay, Operation Meghdoot, Operation Cactus and Operation Poomalai. The IAF's mission expands beyond engagement with hostile forces, with the IAF particip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HPT-32 Deepak
The HAL HPT-32 Deepak ("lamp" in Sanskrit) is an Indian prop-driven primary trainer manufactured by Hindustan Aeronautics Limited. It has two seats in side-by-side configuration. Operational history The Deepak is used for primary training, observation, liaison and target towing. When it flies upside-down fuel flows from a collector tank in the fuselage and the inverted flight is limited to 1 min. Deepak has a theoretical glide ratio of 8.5:1. The IAF and HAL are looking into new safety systems such as Ballistic Recovery Systems to enable it to descend safely in the event of an engine failure. On 16 May 2010 the IAF cleared the installation of a parachute recovery system. The HPT-32 aircraft has been replaced by the Pilatus PC-7 Mk II in the IAF, as its workhorse as a Basic Trainer Aircraft (BTA) in 2013. Accidents In 17 Deepak crashes so far, 19 pilots have died. The Comptroller and Auditor General (CAG) of India has been reported as saying the aircraft is "technologically ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pilatus PC-7
The Pilatus PC-7 Turbo Trainer is a low-wing tandem-seat training aircraft designed and manufactured by Pilatus Aircraft of Switzerland. The aircraft is capable of all basic training functions including aerobatics, instrument, tactical and night flying. The PC-7 was developed from the preceding Pilatus P-3, largely differing by the adoption of a turboprop engine, a bubble canopy, and a new one-piece wing. Introduced during the 1970s, it has since developed a sizable presence of the global trainer market. The type has been adopted by in excess of 20 air forces as their ab initio trainer, as well as multiple civilian operators. Over one million hours have reportedly been flown by PC-7s worldwide. In addition to training operations, some aircraft are armed and have been used for combat missions by several customers, including Chad, Iran, and Mexico, often in violation of the relevant export agreement between the customer and the Swiss government. An improved model of the aircraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeywell TPE331
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.

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 is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

Pilatus PC-21
The Pilatus PC-21 is a turboprop-powered advanced trainer with a stepped tandem cockpit. It is manufactured by Pilatus Aircraft of Switzerland. Development In November 1997 Pilatus flew a modified PC-7 Mk.II in order to test improvements for a prospective next generation turboprop trainer. As a result of these tests, Pilatus elected to fund the development of a new training system in November 1998; development of the new trainer, designated as the ''PC-21'', formally started in January 1999. The PC-21 would be developed and certified as a completely new training system, aimed at meeting future military customers' specifications in terms of capability and life-cycle costs for the next three decades. A key aim for the PC-21 was to allow jet aircraft pilots to perform the majority of their training using the type before converting to jet-powered types, allowing operators to make substantial savings. In order to achieve this aim, the new trainer was required to have an expanded pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuji T-7
The Fuji T-7 (previously T-3 Kai) is a Japanese primary trainer aircraft built by Fuji Heavy Industries for the Japan Air Self-Defense Force. A development of Fuji's earlier T-3 trainer, it is a single-engined monoplane powered by a turboprop engine. Design and development The Fuji T-7 was developed to meet a requirement of Japan's Air Self Defence Force for a primary or basic trainer to replace the Fuji T-3. The resultant aircraft was a modified version of the T-3, (itself descended via the Fuji KM-2 from the Beech T-34) and shared the single-engined low-winged monoplane layout of the T-3, but replaced the Lycoming piston engine with an Allison 250 turboprop engine. The T-7 was selected in preference to the Pilatus PC-7 in 1998,Mollet 1998, p.31. but this decision was cancelled and the competition restarted after a corruption scandal arose, with several managers from Fuji being arrested for bribing an official in Japan's ruling Liberal Democratic Party.Jeziorski 2000, p. ...

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] |
