New progress in aviation manufacturing decarburization

The new coronary pneumonia's epidemic has not stopped the pace of sustainable development of the global aviation industry.

On June 21, the International Aviation Transportation Association (IATA) appealed at Doha: governments of various countries should formulate large -scale incentive measures to quickly expand the use of sustainable aviation fuels (SAF, Sustainable Aviation Fuel). According to data released by the International Airlines Association, in 2021, the available output of sustainable aviation fuels around the world was 125 million liters. Although the price was two to four times that of traditional aviation fuel, airlines still bought each drop. Through expectations and calculations, the International Aviation Association has obtained a phased goal: if governments of various countries support global sustainable aviation fuel output reached 30 billion liters in 2030, it will usher in a turning point to send a clear signal to the market. Bring high output and low prices. To achieve a small goal of this stage, sustainable aviation fuel may play an expected role in reducing carbon emissions.

This is part of the plan. The plan was established by the International Civil Aviation Organization (ICAO) in October last year: Global aviation transportation goals to achieve net zero emissions in 2050.

Climate and environmental issues are closely related to everyone. Governments, civil aviation bureau, airlines, airports, air transport management departments, and aviation manufacturing companies are conducting operations to explore innovation paths from the aspects of technology, operation, sustainable aviation fuel and carbon deduction Essence "What to burn in the aircraft" is always a key area for scientific and technological innovation. How is the development prospects of sustainable aviation fuel? Hydrogen energy vehicles have galloped outside the Beijing Winter Olympics. Is it feasible for hydrogen power aircraft? What else to develop clean energy to provide motivation for aircraft?

100%sustainable aviation fuel

On June 21, Pratt & Whitney Canada carried out 100%sustainable aviation fuel flight test, and the test was successful.

This flight test was performed on an ATR72-600 aircraft equipped with a dual PW127M turbine engine. This is a plane of a Braun Airlines. Both PW127M engines use Neste My sustainable aviation fuel. The aircraft took off from the Malmo Airport in Sweden. Mama Airport.

In the first decade of the 21st century, the compatibility of sustainable aviation fuel for inclusive Canadian engines was only 50%. This is the first time they have achieved 100%sustainable aviation fuel flight. This pair of PW127M engine is also the world's first turbine engine that achieves this goal. The turboprop engine is reduced by 40%compared with the fuel consumption and the emissions of 40%than the fuel consumption. Compared with traditional kerosene, sustainable aviation fuel can reduce emissions by 80%, which is an important solution for future long route flights.

Full electric

On June 21, the US "Aviation Weekly" website reported that German startup VAERIDION plans to develop a 500 -kilometer range, which can carry nine passengers full electric branch passenger planes. Its cruise speed is 130 to 170 sections (241-315 km/h), with a maximum take -off weight of 5.7 tons. It is reported that the first step of the development plan is to integrate the battery system to the wing, which can effectively reduce weight.

In September 2021, former Airbus engineer Ivor Van Dartel and Sebastian Seemann founded VAERIDION. They previously participated in the E-Fan X hybrid power demonstration project of Airbus. VAERIDION is in the conceptual design stage of aircraft and system architecture. Under the premise of considering the requirements of the European CS-23-level certification, the structure of the wing will be carried out in detail, the structure of the battery and the wing box, and then the structure of the wing will be launched. Make and test the battery pack with integrated functional structure.

Hydrogen power

Hydrogen -powered aircraft is also part of the net zero -carbon emissions plan. It is now predicting that it will be used more for short -distance routes. Earlier this year, Airbus signed a cooperation agreement with the CFM International Corporation to jointly launch a hydrogen demonstration project around 2025. The project aims to conduct ground and flight testing of hydrogen fuel engines, and prepares a zero -emission aircraft into use by 2035. They will use an Airbus A380 to test the aircraft as the flight test platform to equip the Airbus's liquid hydrogen can. Airbus will also be responsible for formulating the requirements for hydrogen promotion systems, supervising the flight test, and providing the A380 platform to test the hydrogen fuel engine during the cruise stage. In order to use hydrogen fuel operation, CFM International will transform the combustion room, fuel system and control system of the GE Passport engine. The engine assembled in the United States is selected for its size, advanced turbine machinery and fuel liquidity. It will be installed on the rear body of the flight test platform to monitor the emissions of the engine (including the tail) and the emissions of the engine that provides power for the aircraft. CFM will complete a large number of ground tests before the A380 flight test.
