First A319neo flight with 100% sustainable aviation fuel

Toulouse, 29 October 2021 – Airbus, Dassault Aviation, ONERA, the French Ministry of Transports and Safran have launched the first in-flight study of a single-aisle aircraft running on unblended sustainable aviation fuel (SAF).

During the flight test over the Toulouse region on 28 October, one CFM LEAP-1A engine of an Airbus A319neo test aircraft operated on 100% SAF. Initial results from the ground and flight tests are expected in 2022.

The unblended SAF is provided by Total Energies. It is made from Hydroprocessed Esters and Fatty Acids (HEFA), which primarily consists of used cooking oil, as well as other waste fats. HEFA is made of paraffinic hydrocarbons and is free of aromatics and sulfur. Approximately 57 tonnes of SAF will be used for the entire test campaign. It is produced in Normandy close to Le Havre, France. The 100% SAF will also be utilised for compatibility and engine operability studies on the Safran Helicopters Arrano engine used on the Airbus Helicopters H160, which are expected to start in 2022.

Airbus, in collaboration with DLR, is responsible for characterising and analysing the impact of 100% SAF on ground and in-flight emissions. Safran focuses on compatibility studies related to the fuel system and engine adaptation for commercial and helicopter aircraft and their optimisation for various types of 100% SAF fuels. Safran will perform LEAP engine ground tests with 100% SAF at its Villaroche facilities later this year to complete analysis. ONERA is supporting Airbus and Safran in analysing the compatibility of the fuel with aircraft systems and will be in charge of preparing, analysing and interpreting test results for the impact of 100% SAF on emissions and contrail formation. Dassault Aviation is contributing to the material and equipment compatibility studies and verifying 100% SAF biocontamination susceptibility.

The study – known as VOLCAN (VOL avec Carburants Alternatifs Nouveaux) – contributes to global decarbonisation efforts currently underway across the entire aeronautical industry, and is benefiting from a financing of the France Relance recovery plan, the part thereof dedicated to the decarbonisation of aviation, which is implemented by DGAC under the supervision of Jean-Baptiste Djebbari, French Minister of Transports. The study’s ultimate goal is to promote the large-scale deployment and use of SAF, and certification of 100% SAF for use in single-aisle commercial aircraft and the new generation of business jets.

China Developing Jet to Travel Anywhere in Two Hours

China is making remarkable strides in aviation technology with its ambitious plan to develop a hypersonic passenger jet, capable of flying at speeds that could revolutionize air travel.

The cutting-edge aircraft, dubbed the “Nanqiang No 1,” aims to reach speeds up to six times faster than the legendary Concorde, potentially transporting passengers to any destination on the globe in under two hours.

This futuristic project has already undergone rigorous testing at a state-of-the-art laboratory in Fujian Province. Reports from China indicate that the unmanned prototype is expected to weigh just 500 kilograms, showcasing a sleek and lightweight design optimized for speed. The jet is projected to cruise at an astonishing Mach 6, or six times the speed of sound, which would set new standards for commercial flight.

The key to achieving such mind-blowing speeds lies in a sophisticated engine design. The “Nanqiang No 1” will utilize a combination of turbofan, rocket, and ramjet engines, pushing the boundaries of what current aviation technology can handle. Early renderings of the aircraft reveal a “MUTTER” engine configuration, which includes two air-breathing ramjet engines, a small rocket engine, and two turbine engines. china 6th generation fighter While there were initial doubts about the feasibility of this engine setup, computer modeling and early lab tests have demonstrated the MUTTER system’s ability to surpass Mach 6.

Though several nations are exploring supersonic and hypersonic flight technology, China’s pursuit of a passenger jet capable of reaching hypersonic speeds puts it at the forefront of this race. Supersonic jets, which travel faster than the speed of sound (Mach 1), are being explored by various aerospace companies worldwide, but China’s vision to push beyond supersonic into the hypersonic realm represents a bold leap into the future of air travel.

With the potential to redefine how people traverse the globe, China’s hypersonic passenger jet could make long-haul flights obsolete, allowing travelers to reach far-flung destinations in a matter of hours. The country hopes to see the technology realized and operational for tourist use within the next decade, marking a new chapter in aviation history.
