Skreemr hypersonic passenger plane design would use electromagnetic launch

A mach 10 hypersonic Skreemr airplane design is the brainchild of Charles Bombardier. Bombardier's latest design describes a passenger aircraft that can travel at 10 times the speed of sound, or just under 8,000 mph (12,348 km/h).

Charles Bombardier holds a Master’s degree in mechanical engineering from the École de Technologie Supérieure in Montreal. He learned the skills of product development at BRP. where he managed the R&D Team for the Ski-Doo Élite and the Can-AM Spyder Roadster. As an Entrepreneur, he started his first business in 1999 and acquired and sold a few others since then including Segway Canada.

Charles Bombardier is also an inventor and angel investor. Bombardier worked for his family's vehicle design and manufacturing company, Bombardier Inc. and Bombardier Recreational Product. Bombardier's grandfather was Joseph-Armand Bombardier, founder of Bombardier Inc. and Bombardier Recreational Products and inventor of the snowmobile. In the 2000s he managed three development projects with Bombardier Recreational Products as engineer and production manager. Bombardier's first development project was the Traxter XL ATV, the first 4X4 straddle type all-terrain vehicle with a cargo box. The second vehicle Bombardier developed and produced was the Ski-Doo Elite Snowmobile, a luxury side-by-side snowmobile. In 2005, Bombardier was given the task to developed the BRP Can-Am Spyder Roadster. It was the first certified on-road motorcycle manufactured by BRP. In 2008 Bombardier founded a private R&D Center and developed electric urban transporters and electric ATV's prototypes.

While working for BRP, Bombardier was also the owner of Segway Canada, but after three years sold his business back to Segway because of the limited market.

Ray Mattison from Design Eye-Q who created the renderings of the Skreemr concept.

Skreemr 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.

How it works

The Skreemr would need to be launched from an electric launch system. This device would make it possible to accelerate the aircraft to high speed. This system would need to be long enough to achieve supersonic speed without taxing the passengers with too much g-force.

The Skreemr would then ignite liquid-oxygen / 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.

It might be possible to skip the rocket part which would be in use from maglev launch to the scramjet ignition, but this would depend on two things: the materials used to withstand the heat and pressure on the aircraft, and the acceleration that could be sustained by the occupants of the aircraft.
