HyperMach Now Shooting For Mach 4.0 Bizjet

HyperMach’s planned 20-seat supersonic business jet (SSBJ)–SonicStar–will be able to fly at speeds up to Mach 4.0.

HyperMach said it is increasing the top speed of its planned supersonic business jet from Mach 3.6 to Mach 4, which would allow the aircraft to fly from New York to Dubai in only 2 hours 20 minutes. The jet won’t enter service until at least 2025.

HyperMach’s planned 20-seat supersonic business jet (SSBJ)–SonicStar–will be able to fly at speeds up to Mach 4.0, the company said on Friday. This is faster than the Mach 3.6 top speed announced when the V-tailed aircraft was first revealed at June’s Paris airshow. At Mach 4.0, the SonicStar would be able to fly from New York to Dubai in only 2 hours 20 minutes.

According to Richard Lugg, CEO of UK-based Hypermach Aerospace, recent analysis of data by partner Eagle Harbor Technologies showed that the higher speed can be achieved while still meeting requirements for a high thrust-to-weight ratio engine, reduced emissions and no (or minimal) sonic boom. The boom is eliminated using an electromagnetically induced plasma wave that “absorbs” pressure waves. “Eagle Harbor integrated [its] plasma and aerodynamic codes into the HyperMach SonicStar aerodynamic model and generated an initial simulation showing that it is possible to manage the shock wave at the bow of the aircraft,” said Lugg.
