has revealed its plans for a hypersonic passenger plane that would be able to travel roughly five times the speed of sound.One of the designs is for a business jet, called the Destinus S. This could carry around 25 people and cruise at an altitude of around 108,000ft – far higher than the usual cruising altitude of a Boeing 737, which is around 41,000ft.At a speed of Mach five , the aircraft would theoretically be able to travel from Paris to New York in just an hour and a half.
Before you start planning a mini-break to the Big Apple though, you should know the plans and designs for this are still very much in the development stage.Destinus expect the first deliveries of the S model to be available in the early 2030s, with Destinus L coming in the 2040s,At the Paris Air show, senior business development manager Martina Löfqvist said: “It’s somewhere of a mix between a rocket and an airplane.
“We’ve been speaking with a lot of airlines and airports who also support the notion that hydrogen will be the future of aviation.”The aircraft will use liquid hydrogen fuel and ramjet engines for power. Meanwhile and turbo will be combined with an afterburner to take the jet from the sedentary pace of subsonic to supersonic speeds.The use of hydrogen fuel is a very deliberate choice, as hydrogen is an effective cooling agent. So, this will ensure the aircraft doesn’t overheat.
In fact, Löfqvist described hydrogen power as being “the core of the company,” saying that it is three times more efficient than traditional jet fuel and doesn’t release carbon emissions.
