Aerion is here in Dubai to tap what it believes could be strong market for the supersonic business jet (SSBJ) it intends to have certified in 2015. According to the U.S. company, it still holds letters of intent for about 50 of the aircraft and has had to refund only two deposits since the start of the financial crisis.

Richard Whitcomb, 88, the long-time NASA engineer des-cribed as the most significant aerodynamics contributor of the second half of the 20th century, died on October 13 in Newport News, Va. He was the recipient of the prestigious Collier Trophy for his discovery of the area rule fuselage, which gave fighter jets supersonic speed and greater range, and his supercritical wing and winglets are found on many of today’s aircraft designs.

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.

If paper was aluminum, glass and titanium instead of just paper, two Nevada-based groups developing supersonic business jet designs would have revolutionary aircraft ready to fly. To date, though, the specifications publicized by Aerion in Reno (Booth No.

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.

Cessna Aircraft yesterday delivered the first Citation X retrofitted with elliptical winglets made by Wichita-based Winglet Technology. The winglets were installed at Cessna’s Wichita Citation Service Center under Winglet Technology’s FAA STC. According to Cessna, the patented elliptical winglets optimize lift distribution, which reduces drag and thereby decreases fuel consumption and increases speed and range.

GE Aviation and NASA are to ground test five sets of new subscale blades for open-rotor engines at NASA’s Glenn Research Center in Cleveland, Ohio. The tests will focus on acoustics and efficiency of a two-stage counter-rotating fan. The two partners have high expectations that new analysis tools will add to their understanding of the fan’s aerodynamics.

Dassault received EASA certification for its Falcon 2000LX on April 23, followed by FAA certification seven days later. Initially slated for certification more than one year ago, the 2000LX is a winglet-equipped version of the 2000EX. According to the French manufacturer, the winglets cut drag by 5 percent and boost range at Mach 0.80 to 4,000 nm from 3,800 nm. The first customer 2000LX was delivered early last month.
