Aerion pushes supersonic bizjet plan


It’s all about the boom

The FAA’s Office of Aviation Policy, Planning, and Environment plans to call a third hearing soon on the topic of sonic booms over populated areas. The United States is the only country to prohibit Mach 1.0 flight over land, Aerion officials said in a press release. The FAA had requested more information on Reno, Nevada-based company’s plans for Mach cut-off, meaning supersonic cruise at Mach 1.15 but with no audible disturbance. By adjusting cruise speed based on temperature data, the sonic shock wave can be prevented from hitting the ground, Aerion officials believe, and will dissipate by a few thousand feet above the ground.

Approach speeds will be 120 knots, and the range is projected to be 4,000 nm at supersonic speeds, or 4,500 nm at subsonic speeds. The goal is to operate from 6,000-foot runways.

A McDonnell Douglas (now Boeing) F–15 fighter will be used for testing late this year at NASA’s Dryden Flight Research Center in addition to wind tunnel testing. The purpose of the tests is to refine the shape of strakes, flaps, elevators, rudder, and engine integration. The data will be used to set production standards. A wing section will be carried aloft to test laminar flow predictions.
