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.

Narrow-body Airliner
A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than , allowing at least seven-abreast seating and often more travel classes. Market Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic, McDonnell-Douglas MD-80 and Airbus A320 were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's wide-body aircraft. The re-engined Boeing 737 MAX and Airbus A320neo jets offer 500 miles more range, allowing them to operate the 3,000 miles transatlantic flights between the eastern U.S. and Western Europe, previously dominated by wide-body aircraft.

Kommersant
(, , ''The Businessman'' or Commerce Man, often shortened to Ъ) is a nationally distributed daily newspaper published in Russia mostly devoted to politics and business. The TNS Media and NRS Russia certified July 2013 circulation of the daily was 120,000–130,000. It is widely considered to be one of Russia's three main business dailies (together with '' Vedomosti'' and '' RBK Daily''). History The original ''Kommersant'' newspaper was established in Moscow in 1909, but was shut down by the Bolsheviks following the October Revolution in 1917. In 1989, with the onset of press freedom in Russia, was relaunched under the ownership of businessman and publicist Vladimir Yakovlev. The first issue was released in January 1990. It was modeled after Western business journalism. The newspaper's title is spelled in Russian with a terminal hard sign (ъ) – a letter that is silent at the end of a word in modern Russian, and was thus largely abolished by the post-revolution ...

Yak-42
The Yakovlev Yak-42 (; NATO reporting name: "Clobber") is a 100/120-seat Trijet, three-engined mid-range passenger jet developed in the mid 1970s to replace the technically obsolete Tupolev Tu-134. It was the first airliner produced in the Soviet Union to be powered by modern high-bypass turbofan engines.Gunston, 1997 Development In 1972, the Yakovlev OKB, design bureau started work on a short- to medium-range airliner capable of carrying 100–120 passengers. It was intended to be a replacement for the Tupolev Tu-134 jet as well as the Ilyushin Il-18, Antonov An-24 and Antonov An-26, An-26 turboprop airliners. While the new airliner was required to operate out of relatively small airfields while maintaining good economy, as many Soviet airports had been upgraded to accommodate more advanced aircraft, it did not have to have the same ability to operate from grass strips as Yakovlev's smaller Yakovlev Yak-40, Yak-40. The requirement resulted in the largest, heaviest and most po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Tupolev Tu-134
The Tupolev Tu-134 (NATO reporting name: Crusty) is a twin-engined, narrow-body jet airliner built in the Soviet Union for short and medium-haul routes from 1966 to 1989. The original version featured a glazed-nose design and, like certain other Russian airliners (including its sister model, the Tu-154), it can operate from unpaved airfields. One of the most widely used aircraft in former Comecon countries, the number in active service is decreasing because of operational safety concerns and noise restrictions. The model has seen long-term service with some 42 countries, with some European airlines having scheduled as many as 12 daily takeoffs and landings per plane. In addition to regular passenger service, it has also been used in various air force, army and navy support roles; for pilot and navigator training; and for aviation research and test projects. In recent years, a number of Tu-134s have been converted for use as VIP transports and business jets. A total of 854 Tu- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 737 MAX
The Boeing 737 MAX is a series of narrow-body aircraft developed by Boeing Commercial Airplanes as the fourth generation of the Boeing 737. It succeeds the Boeing 737 Next Generation and incorporates more efficient CFM International LEAP engines, aerodynamic improvements such as split-tip winglets, and structural modifications. The program was announced in August 2011, the first flight took place in January 2016, and the aircraft was certified by the U.S. Federal Aviation Administration (FAA) in March 2017. The first delivery, a MAX 8, was made to Malindo Air in May 2017. The 737 MAX series includes four main variants—the MAX 7, MAX 8, MAX 9, and MAX 10—with increasing fuselage length and seating capacity.

Airbus A320neo
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus. The A320neo family (''neo'' being Greek for "new", as well as an acronym for "new engine option") is based on the Airbus A320 family#A320 Enhanced, enhanced variant of the previous generation A319, A320, and A321, which was then retroactively renamed the A320ceo family (''ceo'' being an acronym for "current engine option"). Re-engined with CFM International LEAP or Pratt & Whitney PW1000G engines and fitted with wingtip device, sharklet wingtip devices as standard, the A320neo is 15% to 20% more fuel efficient than prior models, the A320ceo. It was launched on 1 December 2010, made its first flight on 25 September 2014 and was introduced by Lufthansa on 25 January 2016. By 2019, the A320neo had a 60% market share against the competing Boeing 737 MAX; in 2023, the Chinese designed Comac C919 joined these two as another direct competitor. , a total of 11,128 ...

Protectionism
Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors and raise government revenue. Opponents argue that protectionist policies reduce trade, and adversely affect consumers in general (by raising the cost of imported goods) as well as the producers and workers in export sectors, both in the country implementing protectionist policies and in the countries against which the protections are implemented. Protectionism has been advocated mainly by parties that hold economic nationalist positions, while economically liberal political parties generally support free trade. There is a consensus among economists that protectionism has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Out Of Autoclave Composite Manufacturing
Out of autoclave composite manufacturing is an alternative to the traditional high pressure autoclave (industrial) curing process commonly used by the aerospace manufacturers for manufacturing composite material. Out of autoclave (OOA) is a process that achieves the same quality as an autoclave but through a different process. OOA curing achieves the desired fiber content and elimination of voids by placing the layup within a closed mold and applying vacuum, pressure, and heat by means other than an autoclave. A resin transfer molding (RTM) press is the typical method of applying heat and pressure to the closed mold. There are several out of autoclave technologies in current use including RTM, same qualified resin transfer molding (SQRTM), vacuum-assisted resin transfer molding (VARTM), and balanced pressure fluid molding. The most advanced of these processes can produce high-tech net shape aircraft components. Processes Resin transfer molding Resin transfer molding (RTM) is a ...
