The aircraft concept is  designed by Canadian engineer and inventor Charles Bombardier. Check  out these artistic renderings of the hypersonic vehicle.      The concept <img src="http://i.livescience.com/images/i/000/079/370/i02/ipad-skreemr-1.jpg?1446587683" alt="" class="fr-fic fr-dii fr-draggable " style="" />      The Skreemr is an aircraft concept that would be launched at very high  speeds 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 travel at 10 times the speed of sound.  (Image credit: Ray Mattison)                                 The background <img src="http://i.livescience.com/images/i/000/079/369/i02/ipad-skreemr-2.jpg?1446587611" alt="" class="fr-fic fr-dii fr-draggable " style="" />             Bombardier said the Skreemr concept aims to ignite people's imagination  around the idea of hypersonic flight. "I added the idea of using a  non-rocket space launch system and conventional rockets to accelerate  the aircraft initially," Bombardier said. "I am aware that the challenge  of defining such an aircraft is very complex, especially at lower  altitude where the air is dense and heat accumulates rapidly on all  surfaces." (Image credit: Ray Mattison)       How it works <img src="http://i.livescience.com/images/i/000/079/368/i02/ipad-skreemr-3.jpg?1446587563" alt="" class="fr-fic fr-dii fr-draggable " style="" />      The Skreemr would need to be launched from an electric launch system,  according to Bombardier. The jet would then ignite liquid oxygen and  kerosene rockets to rise up in altitude and reach a speed of Mach 4 (or  maintain it after being released from the railgun). The plane would then  ignite its scramjet engine and burn hydrogen and compressed oxygen to  continue its acceleration. (Image credit: Ray Mattison)       The future of launches <img src="http://i.livescience.com/images/i/000/079/367/i02/ipad-skreemr-4.jpg?1446587367" alt="" class="fr-fic fr-dii fr-draggable " style="" />      Scramjet engines are already being developed in the U.S. and China, but  it will likely be years before the technology is used on military  drones. But, perhaps in the distant future, Bombardier said, they could  be used to fly passengers across oceans at very high speeds. (Image  credit: Ray Mattison)       What for? <img src="http://i.livescience.com/images/i/000/079/366/i02/ipad-skreemr-5.jpg?1446587317" alt="" class="fr-fic fr-dii fr-draggable " style="" />      The Skreemr jet would be used as a commercial aircraft to ferry  passengers efficiently from one continent to the next. It could carry  around 75 passengers and would fly five times faster than the Concorde, a  now-retired commercial supersonic jet, according to Bombardier.
