The trial was conducted at the company's Airbreathing Test Facility in Orange County, Virginia, and involved a full-scale engine tested at conditions simulating high-altitude, high-speed flight.

It can make full use of favourable ignition conditions such as high temperatures in reflow region and low velocity as well as high turbulent scale.

The mechanical smoke exhaust experiments with different air-supplement conditions were conducted in a full-scale large space fire experimental hall.
