The rivalry between Airbus and Boeing may have attracted the most attention at the Paris Air Show 2019 this week, but it was a new technology that dominated behind the scenes.
Aerospace currently accounts for around 2.5% of global carbon emissions and The industry has committed to halve its presence in 2005 by 2050 through a mitigation program. That's why engineering firms at the annual event, the largest in the aerospace industry, wanted to showcase a number of environmentally-friendly inventions such as hybrid engines, urban mobility vehicles and autonomous flight systems.
"The Paris Air Show is an exhibition essentially forward-looking and inspiring. That's why innovation is one of the main themes of this 53rd edition, "said the Paris organizers.
It's not just environmental issues driving research: UBS estimates that hybrid vehicle sales will reach $ 1
For these reasons, big companies such as Airbus, Boeing, Bell and Embraer are joining forces with technology companies such as Intel, Amazon, and Siemens to explore new opportunities, with much of the focus being on hybrid engines used for starting and climbing provide electrical boost. If engineers break down hybrid powertrains, airlines can hope for 30% fuel savings, making flying cheaper and greener for everyone.
"We need to make aviation grow and be sustainable," Rolls-Royce CTO Paul Stein told reporters in Paris, where the British engineering giant announced the acquisition of Siemens' aerospace and aerospace division.
"Consumers are likely to demand acceleration in this area," added Celine Fornaro, director of industrial research, UBS. "It is becoming ever more present in everyone's conscience."
Here is a short selection of the most important civilian technologies exhibited at the Paris Air Show:
The Eviation Alice, an electric plane
World's first billed The Israel-made Alice is an all-electric full-size aircraft Designed to fly at a cruising speed of 240 knots (276 mph) up to 650 miles without causing emissions. This may make it the most environmentally friendly city hopper in the world. Eviation Aircraft wants to save 70% in operating costs compared to conventional jets thanks to a three-motor drive system and a 3,500 kg battery.
"This is not a plane a future perhaps. It's there, ready and waiting, "said Evian CEO Omer Bar-Yohay to reporters in Paris before declaring that the plane will be in test flight in Arizona later this year. If all goes well, Alice will be submitted to certification by the Federal Aviation Administration in 2020. Production will begin in the US in 2021. Delivery of the 4 million dollar environmental aircraft is scheduled for 2022, with the US regional carrier Cape Air has already signed a contract to buy up to 92 models.
United Technologies & # 39; Project 804, a hybrid electric add-on
The auto industry has made electric and hybrid electric transport a reality on the ground. Now United Technologies wants to bring it to life with "Project 804", which expands an existing aircraft with new battery technology and a 2 megawatt hybrid electric drive system.
"We basically take a turboprop regional aircraft and build it during take off and climb About half of the power is supplied electrically and about half of the power from the engine. "Paul Eremenko, Chief Technology Officer of United Technologies, told CNBC in Paris: If this is successful, UT assumes that Project 804 will cut fuel costs The company aims to fly a demonstration aircraft by 2022.
The Airbus Vahan, a Flying Taxi
Airbus refers to its Skunkworks project Vahana as an electric self-propelled vertical take-off and landing craft (VTOL). "For all Others, however, are always referred to as a "flying taxi."
The 8-engine Vahana first flew to the United States in January 2018, proving in May 2019 that its tandem tipper can easily handle the transition from vertical takeoff to forward flight. With an estimated range of 31 miles and a cruising speed of 100 knots (115mph), the Vahana is up to four times faster than Airbus, according to Airbus estimates. Fully electric, it is also far more environmentally friendly.
The Vahana may not appeal to nervous flyers: It is single-seated and fully self-propelled, so no pilot pulls a joystick or brings flight attendants food – or drink. Instead, it relies on a set of sophisticated detection and avoidance systems to circumvent birds, drones, and other flying hazards that cross each other by accident. However, you do not need to lose your sleep: Airbus, which is also developing a second electric van called CityAirbus, does not plan to put the Vahana into operation. It is a pure experimental vehicle with which Airbus develops its technology.
XB-1 and Overture by Boom Supersonic, super fast jets
Boom Supersonic (Boom) from Colorado presented the technical milestones in Paris with the two-seat supersonic jet XB-1 intended to lay the foundation for the creation of a supersonic passenger aircraft called Overture. With the use of composites and new engine technology, Boom believes that the Overture will be the fastest, cleanest and cheapest supersonic passenger aircraft in history – though that does not mean it's going to be environmentally friendly.
"Today we have the advanced technology to make faster air travel possible. Our Teams have been working tirelessly to build the first civilian supersonic aircraft since Concorde in recent years, "said Blake Scholl, Boom's CEO, to reporters in Paris.
Boom, which maintains a strategic partnership with Japan Airlines (JAL) The goal is to launch the XB-1 in December 2019, with supersonic flight scheduled for 2020. According to the FAA, it is one of four commercial companies seeking certification of supersonic passenger aircraft in the US to advance the development of the aircraft, the FAA Agency is working to "enable the return of civil supersonic flights while ensuring security The environmental impact is understood and properly taken into account, "said FAA acting Administrator Dan Elwell in Paris on Monday.
