Sonic boom

October 2, 2009 - 9:23am

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.

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.

NASA and Gulfstream last month wrapped up six weeks of flight testing at the Dryden Flight Research Center at Edwards AFB in California aimed at proving whether pilots can use high-definition video cameras and LCD monitors to take off and land a supersonic business jet (SSBJ) in lieu of natural forward vision.

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.

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.

It is almost five years since the Concorde retired, but little has been achieved in terms of replacing the world’s most iconic commercial aircraft.

Aerion is still hoping to convince an OEM partner to join it by the end of this year in its quest to build a supersonic business jet capable of sprinting from New York to London in just four hours. In the six months since the company began accepting orders for the sleek, $80 million twinjet, 40 would-be buyers have signed letters of intent backed by refundable deposits of $250,000.
