Gulfstream reported that its Quiet Spike sonic-boom mitigator successfully achieved supersonic flight on October 20. The OEM has been flight-testing the structural integrity of its Quiet Spike since mid-July. Mounted on the nose of a NASA F-15B and flown at Mach 1.2, the Quiet Spike operated as designed. It extended to its maximum length of 24 feet and performed as expected during the 1.5-hour test flight.
Gulfstream Aerospace has appointed Gerard Schkolnik as director of its supersonic technology programs. Among other projects, the former NASA engineer will work on sonic-boom suppression. Gulfstream has under study a proposed “quiet supersonic business jet.”
Gulfstream is using this NASA F-15B to test a “telescopic quiet spike” that the company hopes will reduce the supersonic noise signature of any potential supersonic business jet. Manufactured from composite materials, the 14-foot-long spike weighs 470 pounds and extends to 24 feet in length for supersonic flight.
Gulfstream secured bragging rights as the first airplane manufacturer to offer synthetic vision, formally launching an SVS certification program at last month’s Farnborough Air Show.
Code-named synthetic vision-primary flight display (SV-PFD), the technology will come to the Gulfstream G350 through G550 as optional software upgrades to the airplanes’ PlaneView cockpits.
