The past couple of years have not been the best of times for a would-be developer to sign deals with industrial partners and customer-users for a new supersonic business jet (SSBJ), but Aerion has been hanging in there and is now seeking to make subsonic aircraft aerodynamically slicker.
A new control surface could reduce induced drag on commercial and business aircraft by up to 14 percent, resulting in fuel savings of more than $400 million per year across the entire U.S. air transport fleet. So claims Utah State University aeronautical engineering professor Warren Phillips, who recently introduced the devices, which he calls “twisterons.”
Aviation Partners (Booth No. 876) is expanding its reach in the winglet modification market with new Hi-Mach Super Critical winglets optimized for the high-speed cruise regime. To date, the company’s Blended Winglets have helped operators enjoy lower fuel burn, higher initial climb altitudes and longer range while flying at long-range cruise speeds. The new Hi-Mach winglets have the same effect, but at Mach 0.80 and above.
