Boeing has begun low-speed wind tunnel tests on the Boeing 777X, the company announced Monday. Testing started on December 5 in Farnborough, UK, at facilities run by testing partner QinetiQ. Boeing and QinetiQ recently signed an agreement to extend the wind tunnel partnership at Farnborough for another five years.
Canada’s National Research Council (NRC) has added new capabilities to its altitude icing wind tunnel (AIWT), such as simulating flights at 25,000 feet and the addition of hot air supply for models that use it for de-icing. The improvements will help NRC meet client demands for development and certification work recognized by regulators such as Europe’s EASA and the U.S. FAA.
Anti-icing surfaces under development at GE and EADS could one day reduce and possibly even eliminate the need for existing anti-icing techniques. Research organizations at the two major aerospace companies are currently working on surfaces that would naturally repel ice without using energy.
The National Research Council of Canada (NRC) has commissioned a wind tunnel to help aircraft manufacturers measure the noise levels generated by aircraft landing gear. Industry historically has focused on measuring and reducing the noise generated only by engines.
Stratos Aircraft has received some external funding and in April and May will conduct wind-tunnel tests of a scale model of the four- to five-place single-engine Stratos 714 very light jet. The tests will take five to ten days using aone-eighth-scale model of the jet and are intended to verify computational fluid dynamics studies of the design.
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.

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.
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.
Cessna yesterday said it completed a series of wind-tunnel tests for its large-cabin Citation Columbus. Results from the tests in low- and high-speed wind tunnels will be analyzed in the coming months, though Cessna said that preliminary data analysis revealed no surprises.
