The Rolls-Royce Trent is a family of high-bypass turbofans produced by Rolls-Royce. It continues the three spool architecture of the RB211 with a maximum thrust ranging from 61,900 to 97,000 lbf . Launched as the RB-211-524L in June 1988, the prototype first ran in August 1990. Its first variant is the Trent 700 introduced on the Airbus A330 in March 1995, then the Trent 800 for the Boeing 777 (1996), the Trent 500 for the A340 (2002), the Trent 900 for the A380 (2007), the Trent 1000 for the Boeing 787 (2011), the Trent XWB for the A350 (2015), and the Trent 7000 for the A330neo (2018). It has also marine and industrial variants like the RR MT30.
A propfan, also called an open rotor engine, or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. A propfan is typically designed with a large number of short, highly twisted blades, similar to the (ducted) fan in a turbofan engine. For this reason, the propfan has been variously described as an "unducted fan" (UDF) or an "ultra-high-bypass (UHB) turbofan".
Safran Aircraft Engines, previously Snecma or Snecma Moteurs, is a French aerospace engine manufacturer headquartered in Courcouronnes and a subsidiary of Safran. It designs, manufactures and maintains engines for commercial and military aircraft as well as rocket engines for launch vehicles and satellites.
The Future Combat Air System (FCAS), is a European combat system of systems under development by Dassault Aviation, Airbus and Indra Sistemas. The FCAS will consist of a Next-Generation Weapon System (NGWS) as well as other air assets in the future operational battlespace. The NGWS's components will be remote carrier vehicles as well as a New Generation Fighter (NGF) - a sixth-generation jet fighter that by around 2040 will replace current France's Rafales, Germany's Typhoons and Spain's EF-18 Hornets.
A blended wing body (BWB), also known as blended body, hybrid wing body (HWB) or a lifting aerofoil fuselage, is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line. This contrasts with a flying wing, which has no distinct fuselage, and a lifting body, which has no distinct wings. A BWB design may or may not be tailless.
Aerosud is a group of companies with Aerosud Holdings as the parent company. The group is a South African aeronautical engineering and manufacturing company. Aerosud Aerospace was renamed Paramount Aerospace following its acquisition by Paramount Group and Aerosud Innovation and Training Centre (ITC) was incorporated in the AHRLAC Holdings Ahrlac of companies during a 2014 restructuring.
A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor. It cannot be stored in a traditional wet wing, and hydrogen tanks have to be housed in the fuselage or be supported by the wing.
The aerospace industry of the United Kingdom is the second-largest national aerospace industry in the world and the largest in Europe by turnover, with a global market share of 17% in 2019. In 2020, the industry employed 116,000 people.
The Eurocopter X³(X-Cubed) is an retired experimental high-speed compound helicopter developed by Airbus Helicopters. A technology demonstration platform for "high-speed, long-range hybrid helicopter" or H³ concept, the X³ achieved 255 knots in level flight on 7 June 2013, setting an unofficial helicopter speed record. In June 2014, it was placed in a French air museum in the village of Saint-Victoret.
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus. The A320neo family is based on the previous A319, A320, and A321, which was then retroactively renamed the A320ceo family.
The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. Endurance and range can be maximized with the optimum airspeed, and economy is better at optimum altitudes, usually higher. An airline efficiency depends on its fleet fuel burn, seating density, air cargo and passenger load factor, while operational procedures like maintenance and routing can save fuel.
The AgustaWestland Project Zero is a hybrid tiltrotor/Lift fan aircraft. It has been developed by AgustaWestland as a technology demonstrator, and is used to investigate all-electric propulsion and other advanced technologies. It is the world's first electric tiltrotor aircraft.
An Electric Green Taxiing System (EGTS) is an electric taxiing system which allows aircraft to taxi and pushback without requiring the use of aircraft engines or a pushback tractor, and is designed to reduce fuel volumes used by aircraft and reduce greenhouse gas emissions during ground operations. EGTS technology enables aircraft to avoid using their main engines during taxiing and instead taxi autonomously under their own electrical power, using the Auxiliary Power Unit (APU) generator. The system is designed for single-aisle aircraft, such as the Airbus A320 and the Boeing 737.
The Airbus Helicopters H160 is a medium utility helicopter developed by Airbus Helicopters. Formally launched at Heli-Expo in Orlando, Florida on 3 March 2015, it is intended to replace the AS365 and EC155 models in the firm's lineup. In June 2015, the first test flight took place. It received its EASA type certification in July 2020, and first deliveries were in December 2021.
The Airbus/Rolls-Royce/Siemens E-Fan X was a hybrid electric aircraft demonstrator being developed by a partnership of Airbus, Rolls-Royce plc and Siemens. Announced on 28 November 2017, it followed previous electric flight demonstrators towards sustainable transport for the European Commission’s Flightpath 2050 Vision. A BAe 146 flying testbed was to have one of its four Lycoming ALF502 turbofans replaced by a Siemens 2 MW (2,700 hp) electric motor, adapted by Rolls-Royce and powered by its AE2100 turboshaft, controlled and integrated by Airbus with a 2 t (4,400 lb) battery. In April 2020, the programme was cancelled during the COVID-19 pandemic.
The Breakthrough Laminar Aircraft Demonstrator in Europe (BLADE) is an Airbus project within the European Clean Sky framework to flight-test experimental laminar-flow wing sections on an A340 from September 2017.
The Airbus RACER is an experimental high-speed compound helicopter developed by Airbus Helicopters from the Eurocopter X³. Revealed at the June 2017 Paris air show, final assembly will start in mid-2020 for a 2021 first flight. Cruising up to 400 km/h (216 kn), it aims for a 25% cost reduction per distance over a conventional helicopter.
The Leonardo Next-Generation Civil Tiltrotor is a tiltrotor aircraft demonstrator designed and developed by the Italian aerospace company Leonardo S.p.A. Studies for a two times larger tiltrotor than the AgustaWestland AW609 started in 2000. Since 2014, its development is sponsored by the European Union's Clean Sky 2 program. By May 2021, major components were under production By 2023, the maiden flight had been pushed back to 2024, from a 2020 initial plan.
A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032.
The CFM International RISE is an open rotor engine currently under development by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. The engine is planned to support both hydrogen and sustainable aviation fuels, and it plans to achieve a 20% reduction in fuel burn and in carbon dioxide emissions compared to its predecessors.
