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.

China has ordered 250 AI-222-25F turbofans from the Ukraine to power production versions of the Hongdu L-15 advanced jet trainer.
Supersonic business jet developer Aerion Corp. (Booth No. N5707) says it has gained traction among aircraft manufacturers with its new aerodynamics consultancy–Aerion Technologies–since the subsidiary was launched in May at the European Business Aviation Convention and Exhibition (EBACE).
GE is here with three major programs at various stages of development. The Passport 20, for Bombardier’s Global 7000 and 8000 large-cabin business jets, has already passed some rig tests. The GE Honda HF120, for the HondaJet and the (currently suspended) Spectrum Freedom, is scheduled for certification in 2012. Meanwhile, the HF80 turboprop is due for certification later this year.
On the opening day at the Paris Air Show, HyperMach took the wraps off a 20-seat, Mach 3.6 business jet that would fly from Paris to New York in just under two hours. Key enabling technologies for the SonicStar include the SonicBlue S-MAGJET five-stage electric-turbine hybrid supersonic 4000-X series engine and a magnetic spike on the nose that can control sonic booms using plasma waves.
HyperMach Aerospace unveiled plans for its 20-seat SonicStar V-tailed, supersonic business jet yesterday at the Paris Air Show. Company CEO Richard Lugg claims the Mach 3.6 aircraft will take no more than one hour 45 minutes to fly from Paris to New York. The SonicStar is scheduled to fly in 2021, with certification possible, but not promised, by 2025.
On Monday at the Paris Air Show, HyperMach Aerospace Industries plans to unveil a “next generation” supersonic business jet (SSBJ) that can fly from Paris to New York in 1 hour 45 minutes.
The past couple of years have not been the best of times for a would-be developer to sign deals with industrial partners and customer-users for a new supersonic business jet (SSBJ), but Aerion has been hanging in there and is now seeking to make subsonic aircraft aerodynamically slicker.
The 7,445-pound-thrust Honeywell HTF7250G turbofan gained FAA certification last month, a company official told AIN. Honeywell Aerospace is now supporting the G250’s flight tests. Next will be the beginning of the actual production phase–the Gulfstream’s HTF7250G test engines were already built according to production processes, Honeywell said.
A bilateral project between NASA and German aerospace research center DLR is expected to focus on the role rotor tip vortices play in helicopter noise by recording vortex velocity fields and rotor-blade deformations by using a test stand with a variety of high-speed cameras, lasers and LEDs that will make the vortices visible. Eventually research will progress to actual helicopters.
