In a move that could help pave the way for low-boom supersonic flight over land, NASA aeronautics researchers are presenting their work on how people on the ground perceive low sonic booms this week in Atlanta at an annual event held by the American Institute of Aeronautics and Astronautics. “Lessening sonic booms is the most significant hurdle to [civil] supersonic flight,” said Peter Coen, head of the high-speed project in NASA’s aeronautics research mission directorate at the agency’s headquarters in Washington, D.C.
Missouri senator Claire McCaskill (Democrat) hit the nail on the head when she wrote to the FAA about easing rules on the use of portable electronic devices (PEDs) in aircraft. Her letter seeks to have the FAA reconsider restrictions on PEDs, citing as one example the fact that many airline pilots are now using switched-on iPads during taxi, takeoff and landing without any problems.
The supersonic business jet development program continues at Gulfstream Aerospace, but until the FAA decides to define “quiet” as it relates to the so-called sonic boom, “We just don’t see a business case,” said a spokesman.
In a series of patent filings last summer, Gulfstream emphasized mitigating the noise produced by the sonic boom, pointing out that regulations currently prohibit supersonic flight over populated areas.
A Gulfstream Aerospace spokesman categorically denied a report published by British tabloid Daily Mail saying that the company, along with NASA, Boeing and Lockheed Martin, would “sketch out” details of a supersonic business jet at the Farnborough Airshow, which starts July 9. Further, Lockheed Martin does not have any civil aircraft announcements planned at the UK airshow.
HyperMach Aerospace’s planned 20-seat supersonic business jet (SSBJ), dubbed the SonicStar, will be able to fly at Mach 4.0, the company said Friday in Dubai. This is faster than the Mach 3.6 top speed announced when the proposed V-tailed aircraft was first revealed in June at the Paris Air Show. At Mach 4, the SonicStar would be able to fly from New York to Dubai in just 2 hours 20 minutes.
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.
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.
Aerion, based in Reno, Nev., is at Booth No. 6202 in NBAA exhibit Hall C to describe preliminary results from the latest round of flight tests of a NASA F-15B on the road to what it envisions as the worlds' first supersonic business jet (SBJ). The tests during July and August in collaboration with NASA's Dryden Flight Research Center achieved a top speed of Mach 2.0.
