NPO Saturn AL-55I
The NPO Saturn AL-55 is a high performance turbofan engine manufactured by NPO Saturn Russia, for powering advanced trainers, unmanned aerial vehicles (UAV) and light attack aircraft. A variant of the AL-55I powers the HAL HJT-36 Sitara Indian jet trainer. Design The design comprises five main features. It has a three-stage low pressure compressor, five stage high pressure chamber, an annular combustion chamber and a single stage high and low pressure turbines. In August 2005, the Russian export organization known as Rosoboronexport and India's Hindustan Aeronautics Limited (HAL) signed an agreement for the licensed production of up to 1,000 AL-55I engines. The agreement includes a firm order for 250 engines to be manufactured at HAL facilities in India, to power both HAL HJT-36 trainer and HAL HJT 39 combat trainer aircraft.

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

NPO Saturn
UEC NPO Saturn, PJSC (russian: ОДК-Сатурн НПО) is a Russian aircraft engine manufacturer, formed from the mergers of Rybinsk Motors and Lyul'ka-Saturn (after Arkhip Mikhailovich Lyulka) in 2001. Saturn's engines power many former Eastern Bloc aircraft, such as the Tupolev Tu-154. Saturn holds a 50% stake in the PowerJet joint venture with Safran Aircraft Engines. The company, founded by Pavel Soloviev, has its headquarters in the town of Rybinsk. History UEC Saturn was established in 2001, following the merger of Rybinsk Motors and Lyulka-Saturn. Rybinsk Motors was established on 20 October 1916 as the Russian Renault automotive plant. In 1917 it started producing aviation engines for the Ilya Muromets aircraft. The company was nationalized in 1918. Rybinsk was originally known as the Kolesov Engine Design Bureau. Kolesov took over the organization from V.A. Dobrynin who founded it in the late 1930s or early 1940s. Under Kolesov's direction, the bureau designed turb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HAL HJT-36 Sitara
The HAL HJT-36 ''Sitara'' ( Sitārā: "''star''") is a subsonic intermediate jet trainer aircraft designed and developed by Aircraft Research and Design Centre (ARDC) and built by Hindustan Aeronautics Limited (HAL) for the Indian Air Force and the Indian Navy. The HJT-36 will replace the HAL HJT-16 ''Kiran'' as the Stage-2 trainer for the two forces. The ''Sitara'' is a conventional jet trainer with low swept wings, tandem cockpit and small air intakes for the engine on either side of its fuselage. It entered limited series production by 2010 but according to the Indian Air Force officials it remained "unfit" for service due to technological issues related to spin test (as of March 2017)., an issue which was only solved in tests in January 2022. In April 2019, ''Sitara'' flew for the first time in three years with a modified air frame to correct its spin characteristics. Design & development HAL started design work on an intermediate jet trainer in 1997. The concept was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Mikoyan MiG-AT
The Mikoyan MiG-AT (russian: МиГ-АТ) is a Russian advanced trainer and light attack aircraft that was intended to replace the Aero L-29 and L-39 of the Russian Air Force. Designed by the Mikoyan Design Bureau and built by the Moscow Aircraft Production Association, the MiG-AT made its first flight in March 1996. It is the first joint aircraft development programme between Russia and France and the first military collaborative project between Russia and the West to reach first flight. The design lost out to the Yakovlev Yak-130 in 2002 in the competition for a government contract, and had also been unsuccessfully marketed to countries such as India, Greece, and those of the Commonwealth of Independent States. Design and development The design effort on the MiG-AT began when Soviet authorities looked to replace the country's ageing fleet of Aero L-29 and L-39 military trainer aircraft. The project competed with proposals from the design bureaux of Sukhoi, Myasishchev and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KB SAT SR-10
The KB SAT SR-10 is a prototype Russian single-engine jet trainer aircraft, fitted with forward-swept wings. It first flew in 2015 and is being offered to the Russian Air Force and for export. Design and development The Russian design bureau KB SAT (''Sovremyenne Aviatsyonne Tekhnologii'' – Modern Aircraft Technologies) began work on a single-engine jet trainer and sport aircraft, the SR-10, in 2007, displaying a mockup at the MAKS airshow at Zhukovsky in August 2009. The SR-10 is a mid-wing monoplane of all-composite construction, with a wing swept forward at an angle of 10 degrees. The crew of two sit in a tandem cockpit. It is powered by a single turbofan, with an Ivchenko AI-25V AI25TSR (modification of AI25TL) fitted in the prototype, but more modern Russian engines, such as the NPO Saturn AL-55 were proposed for production aircraft.Butowski 2016, p. 15.
