How would a nuclear powered aircraft work?
The nuclear reactor core would heat up pressurized water or liquid metal and send it to the heat exchanger as well. That hot liquid would be cooled by the air; the air would be heated by the liquid, sent through a turbine (powering the compressor), then out the exhaust, providing thrust.
Who invented the jet?
Hans von Ohain of Germany was the designer of the first operational jet engine, though credit for the invention of the jet engine went to Great Britain’s Frank Whittle. Whittle, who registered a patent for the turbojet engine in 1930, received that recognition but did not perform a flight test until 1941.
Why don’t electric planes fly longer distances?
Using a heavy energy source thus means more energy is needed for a flight, which leads to extra mass, and so on and on. For an aircraft, mass is crucial, which is why airlines fastidiously weigh luggage. Electric planes need batteries with enough energy per kilogram of battery, or the mass penalty means they simply can’t fly long distances.
Is this the world’s first all-electric commercial plane?
Ampaire hopes to get its new plane, the Electric Eel, certified for commercial flights by 2021. And, finally, over in Vancouver, electric-motor manufacturer MagniX and Vancouver-based airline Harbour Air flew a retrofitted 62-year-old plane. A 15-minute test flight in December 2019 made it the world’s first all-electric commercial plane to fly.
When will electric planes be allowed on commercial flights?
Los Angeles company Ampaire replaced one of the two engines in a 1973 Cessna with an electric one. Ampaire hopes to get its new plane, the Electric Eel, certified for commercial flights by 2021. And, finally, over in Vancouver, electric-motor manufacturer MagniX and Vancouver-based airline Harbour Air flew a retrofitted 62-year-old plane.
Why do planes need so much energy to fly?
But that is only part of the story. Aircraft also travel much further than ground vehicles, which means a flight requires far more energy than an average road trip. Aircraft must store onboard all the energy needed to move its mass for each flight (unlike a train connected to an electrical grid).
