Tupolev Tu-204
The Tupolev Tu-204 () is a twin-engined medium- range narrow-body jet airliner capable of carrying 210 passengers, designed by Tupolev and produced by Aviastar-SP and Kazan Aircraft Production Association. First introduced in 1995, it was intended to be broadly equivalent to the Boeing 757, with slightly lower range and payload, and had competitive performance and fuel efficiency in its class. It was developed for Aeroflot as a replacement for the medium-range Tupolev Tu-154 trijet in the 1990s. The latest version, with significant upgrades and improvements, is the narrow-body Tu-204SM, which made its maiden flight on 29 December 2010. In April 2022, United Aircraft Corporation (UAC) announced plans to assemble 70 Tu-214s by 2030. However, in early 2024, Aeroflot expressed intention to transfer its order for fleets exclusively to next-generation MC-21 jets. The rejection of the Tupolev has various reasons, including no two-member cockpit, and also the evacuation ramps and ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Koryo
Air Koryo () is North Korea's flag carrier and only commercial airline. It is state-owned and controlled by the North Korean air force. Headquartered in Sunan-guyŏk, Pyongyang, it operates domestic and international routeson a regular schedule only to Beijing, Shenyang, and Vladivostokfrom its hub at Pyongyang’s Sunan International Airport. It also operates flights on behalf of the North Korean government, with one of its aircraft serving as North Korean supreme leader Kim Jong Un's personal plane. Its fleet consists of Ilyushin and Tupolev aircraft from the Soviet Union and Russia, and Antonovs from Ukraine. Air Koryo's history can be traced to the founding of the Soviet–North Korean Airline (SOKAO) in 1950. Following the Korean War, in 1955, the airline was reorganized as Korean Airways and started domestic and international routes to other communist Eastern Bloc states in Asia and Europe. Another reorganization followed after the collapse of the Soviet Union, and in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Range (aircraft)
The maximal total range is the maximum distance an aircraft can fly between takeoff and landing. Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the air. The fuel time limit for powered aircraft is fixed by the available fuel (considering reserve fuel requirements) and rate of consumption. Some aircraft can gain energy while airborne through the environment (e.g. collecting solar energy or through rising air currents from mechanical or thermal lifting) or from in-flight refueling. These aircraft could theoretically have an infinite range. Ferry range means the maximum range that an aircraft engaged in ferry flying can achieve. This usually means maximum fuel load, optionally with extra fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulyanovsk
Ulyanovsk,, , known as Simbirsk until 1924, is a types of inhabited localities in Russia, city and the administrative center of Ulyanovsk Oblast, Russia, located on the Volga River east of Moscow. Ulyanovsk has been the only Russian UNESCO City of Literature since 2015. The city was the birthplace of Vladimir Lenin (born Ulyanov), for whom it was renamed after his death in 1924; and of Alexander Kerensky, the leader of the Russian Provisional Government which Lenin overthrew during the October Revolution of 1917.

Rolls-Royce RB211
The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce Holdings, Rolls-Royce. The engines are capable of generating of thrust. The RB211 engine was the first production turbofan#Three-spool, three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader. Originally developed for the Lockheed L-1011 TriStar, it entered service in 1972 and was the exclusive engine to power the L-1011. Mismanagement of the initial development and consequent cost issues led to the effective nationalisation of Rolls-Royce Limited, to save the workforce and the engine businesses important to the UK and many other aerospace and aircraft operating companies. In the early 1970s, the engine was reckoned by the company to be capable of at least 50 years of continuous development. The RB.211 was renamed, in 1989, to become the basis of the Rolls-Royce Trent family of engines when the RB211-524L was renamed to the ...

Traffic Collision Avoidance System
A traffic alert and collision avoidance system (TCAS), pronounced ), also known as an Airborne Collision Avoidance System (ACAS), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active Transponder (aviation), transponder, independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of MAC. It is a type of airborne collision avoidance system mandated by the International Civil Aviation Organization to be fitted to all aircraft with a maximum take-off mass (MTOM) of over or authorized to carry more than 19 passengers. In the United States, Federal Aviation Regulations, CFR 14, Ch I, part 135 requires that TCAS I be installed for aircraft with 10–30 passengers and TCAS II for aircraft with more than 30 passengers. ACAS/TCAS is based on secondary su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev MC-21
The Yakovlev MC-21 () is a Narrow-body airliner, single-aisle airliner, under development in Russia by the Yakovlev Corporation (formerly known as Irkut Corporation), a branch of the United Aircraft Corporation (UAC), itself a 92%-owned subsidiary of Russia's state-owned aviation giant Rostec. The variant MC-21-310 of the airliner powered by the Russian-made Aviadvigatel PD-14 engine made its maiden flight on 15 December 2020 from Irkutsk. Project history The program to build the MC-21 was launched in 2007. Irkut rolled out the first MC-21-300 with Pratt & Whitney engines on 8 June 2016 and first flew the aircraft on 28 May 2017. The twinjet has a carbon fibre reinforced polymer wing and was to be powered by Aviadvigatel PD-14 turbofans or Pratt & Whitney PW1000G engines. By July 2018, the company had received 175 firm orders. In early 2022, international sanctions against Russia were imposed due to the Russian invasion of Ukraine.

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Trijet
A trijet is a jet aircraft powered by three jet engines. In general, passenger airline trijets are considered to be second-generation jet airliners, due to their innovative engine locations, in addition to the advancement of turbofan technology. Trijets are more efficient than quadjets, but not as efficient as twinjets, which replaced trijets as larger and more reliable turbofan engines became available. Types still in production The Dassault Falcon 7X/8X and the Dassault Falcon 900 are the only civilian trijets in production and the Chengdu J-36 is the only military trijet in production. Design One consideration with trijets is positioning the central engine. This is usually accomplished by placing the engine along the centerline, but still poses difficulties. The most common configuration is having the central engine located in the rear fuselage and supplied with air by an S-duct, S-shaped duct; this is used on the Hawker Siddeley Trident, Boeing 727, Tupolev Tu-154, Loc ...

Tupolev Tu-154
The Tupolev Tu-154 (; NATO reporting name: "Careless") is a three-engined, medium-range, narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger-km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries. The aircraft has a cruising speed of and a range of . Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions, where other airliners were unable to operate. Originally designed for a 45,000-hour service life (18,000 cycles), but capable of 80,000 hours with upgrades, it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
