An innovative engineer has developed a concept aircraft that – at least in theory – could cross the Atlantic in just 30 minutes.
Skreemr is the name of the concept plane developed by inventor and engineer Charles Bombardier. Details about the aircraft prototype were written by Bombardier in the the Canadian newspaper The Globe and Mail.
It is a passenger aircraft that can travel under 8,000 miles per hour (12,348 kilometres per hour), which is just about ten times the speed of sound.
Bombardier explains that the Skreemr aircraft would have to be launched from a magnetic rail gun system, to reach the Mach 10 speed. The Mach number is defined as the ratio of local flow velocity past a boundary to the local speed of sound (M= u/c).
The jet would be five times faster than the Concorde supersonic passenger jet – which is no longer in function – that reached a Mach 2.04 speed (1,565 miles per hour or 2,519 kilometres per hour – that is more than twice the speed of sound).
Magnetic rail guns produce an electromagnetic field that can propel an aircraft at very high speeds. According to Bombardier, the jest’s kerosene rockets and liquid oxygen would ignite as soon as the plain would go beyond the speed of sound (more than 767 miles per hour, or 1,235 kilometres per hour) after its launch.
The rockets would help the Skreemr jet climb in altitude and reach a speed of Mach 4 (more than 3,000 miles per hour, or 1,220 kilometres per hour). Then, the supersonic combustion ramjet engine (scramjet) of the aircraft would ignite – burning up compressed oxygen and hydrogen – which would propel Skreemr forward at speeds higher than Mach 10 (more than 7,600 miles per hour, or 1,220 kilometres per hour).
NASA says that to create thrust, supersonic combustion ramjet engines combine oxygen with liquid fuel. The oxygen in a supersonic combustion ramjet engines comes from the atmosphere itself rather than a tank aboard the aircraft.
The futuristic prototype would carry approximately 75 passengers, but this will not take place any time soon as the supersonic combustion ramjet engines are still under development in the United States and Chine, and their real-life applications still have a long way to go.
