Hypermach SonicStar, a business jet which will be capable of a top speed of 2,664mph – twice as fast as Concorde; and fly at 62,000ft, allowing passengers to see the curvature of the earth. With that speed, a traveller just need two hours to fly from London to New York, five hours from New York to Sydney, a cut by a staggering 75 per cent from a commercial airliner.

Recently unveiled at the Paris Air Show, the 20-seat plane will be able to cruise at Mach 3.1, a speed made possible by S-MAGJET hybrid gas turbine engine technology; nobody has ever travelled that fast before. Its top speed, however, will be Mach 3.6.

With relatively low fuel consumption, the Sonic Star will overcomes the economic and environmental challenges of supersonic flight. By using electromagnetic currents across the fuselage to suppress the sonic boom, the plane is able to overcome the noise regulations that constrict supersonic travel. It has a range of 6,000 nautical miles and its 54,700 thrust class S-MAGJET engine - actually two engines - is optimised to fly the aircraft at 62,000ft. But it is the reduction in jet engine emissions that HyperMach believes will prove the secret of SonicStar's success.

HyperMach plans to build its engine by the end of the decade and to have the plane itself constructed by 2025.
