High-Speed AirCraft (Hisac), a European research program studying the feasibility of a supersonic business jet (SSBJ), is coming to a close at the end of this year. The research has shown better understanding of the performance such a vehicle could achieve, but it came to no conclusion about the types of engines that would be needed.
High-speed aircraft (Hisac), a European research project to study the feasibility of a supersonic business jet (SSBJ), is coming to a close at the end of this year, having shown better understanding of the achievable performance but without an answer to the big question mark on engines. Dassault has led the program, which counts Italy’s Alenia Aeronautica and Russia’s Sukhoi among its other major stakeholders.
Sennheiser Aerospace (Booth No. 1196) is exhibiting its newest aviation headset, the HME 26/HMEC 26, for which the company guarantees reliable voice transmission in the cockpits of jets and propeller airplanes.
Reductions in supersonic boom intensity could allow for overland operation of future supersonic civil aircraft, according to a panel of supersonic technology experts at a meeting held on March 1 in Palm Springs, Calif. The session was part of the UC Davis Aviation Noise & Air Quality Symposium.
A new thermal/acoustic barrier package promises to reduce cabin noise by as much as 30 percent. The Silentium Air SPS 360 is a product of Aviation International Management Services (AIMS) of Montreal, which is supplying the kits to exclusive marketing agent Zenith Jet, also of Montreal.
Would-be manufacturers of supersonic business jets–Aerion, Gulfstream and Supersonic Aerospace International–are encouraged by an updated FAA policy statement that aligns noise limits for future civil supersonic aircraft with current Stage 4 noise regulations. According to the FAA, this action is intended to provide guidance on noise limits for supersonic jets.
Aerion, the U.S. company that is developing a supersonic business jet (SSBJ), has welcomed an FAA policy shift which it believes “seems to crack open the door for supersonic cruise speeds” if, in the words of FAA policy guidance released last month, “the noise impacts of supersonic flight are shown to be acceptable.”
Hopeful manufacturers of supersonic business jets–Aerion, Gulfstream and Supersonic Aerospace International–are encouraged by an updated FAA policy statement issued last week to align noise limits for future civil supersonic aircraft with current Stage 4 noise regulations.
“Everybody talks about the weather,” Mark Twain once famously quipped, “but nobody ever does anything about it.”
Gulfstream has recruited company veteran Robert Cowart to be the new director of supersonic technology development. He most recently served as project engineer for the supersonic technology program. In his new position, Cowart is responsible for the development of advanced technology supporting quiet supersonic flight over land, with a principal focus on sonic boom suppression concepts.
