The Skreemr is an aircraft concept that would be launched at very high speed with the help of a magnetic railgun launching system. Rockets would increase the aircraft speed enough to ignite its main scramjet engine, making it possible to reach speeds over Mach 10.
Designers Charles Bombardier and Ray Mattison envisage the craft could be launched using a magnetic railgun system to catapult it into the sky at high speed
Using such a launch system, the craft would be positioned on a pair of conductive parallel rails and accelerated along them using a powerful electromagnetic field.
Liquid-oxygen or kerosene rockets would be fired to enable the plane to rapidly climb higher in the sky and reach Mach 4, which is around twice the speed of Concorde, The Globe and Mail reported.
