Aerion said today that it plans to fly a “more representative” wing test article for its supersonic business jet this summer. Following supersonic tests in 2010 aboard a NASA F-15B, the company has refined the wing design and plans to use the same aircraft to conduct another round of tests in June or July. Fabrication of the 40-inch vertical span by 80-inch chord test article is now under way and will be complete by the end of next month, it said.
University of Cambridge Professor Holger Babinsky has created a one-minute video to dispel the myth that an airplane wing generates lift because the airflow moving over the upper surface has a longer distance to travel and “needs to go faster to have the same transit time as the air traveling along the lower, flat surface.” What actually causes lift, he said, “is introducing a shape into the airflow, which curves the streamlines and introduces pressure changes–lower pressure on the upper surface and higher pressure on the lower surface.
The FAA has issued a proposed advisory circular that would, as a core principle, include “emphasis of ‘reduce angle of attack’ response as the primary response for stall events.” According to the proposed AC, “The primary goal of this proposed advisory circular is to provide training, testing and checking recommendat
Safe Flight Instrument is celebrating its 65th anniversary with several new programs, including a speed-control system for the Cessna 400 and 208, Lancair Evolution, Quest Kodiak and Viking Twin Otter and autothrottles for the Gulfstream G150, Cessna Citation X and Hawker 800 series.
Aerodynamics of Waterford, Mich., recently completed its second STC installation of an Aircell high-speed Internet with WLAN system in a Hawker 800XP. The installation was completed within the scheduled 2.5-week downtime and was delivered ahead of schedule, it noted.
HyperMach Aerospace’s planned 20-seat supersonic business jet (SSBJ), dubbed the SonicStar, will be able to fly at Mach 4.0, the company said Friday in Dubai. This is faster than the Mach 3.6 top speed announced when the proposed V-tailed aircraft was first revealed in June at the Paris Air Show. At Mach 4, the SonicStar would be able to fly from New York to Dubai in just 2 hours 20 minutes.
HyperMach’s planned 20-seat supersonic business jet (SSBJ)–SonicStar–will be able to fly at speeds up to Mach 4.0, the company said on Friday. This is faster than the Mach 3.6 top speed announced when the V-tailed aircraft was first revealed at June’s Paris airshow.
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.
Avionics manufacturer Aerosonic (Booth No. C13225) received a new purchase order from Korea Aerospace Industries (KAI) this summer to supply air data systems for T-50 Golden Eagle jet trainers sold to Indonesia, Korea’s first T-50 export customer.
Supersonic business jet developer Aerion Corp. (Booth No. N5707) says it has gained traction among aircraft manufacturers with its new aerodynamics consultancy–Aerion Technologies–since the subsidiary was launched in May at the European Business Aviation Convention and Exhibition (EBACE).
