Chatterton Scramjet/Ramjet Engines Speeds greater than Mach 5, which is equivalent to speeds equal or greater than approximately one mile per second or about 3,600 miles per hour are called hypersonic. Normal passenger planes fly at a speed near Mach 0.8, military jets fly at a speed close to Mach 2, and the fastest type of jet, the SR-71 Blackbird, the flies at a top speed of Mach 3.2. Currently there are numerous projects in the works that are trying to develop new types of “air breathing” engines that will allow aircraft to reach higher speeds. The hope is that these new engines will allow increase payload capacity, or reduce of the size of the vehicle needed for the same payload currently associated to larger vehicles. The challenge for completing this new hypersonic traveling technology is “one of the greatest aeronautical research challenges," according to NASA. In a conventional rocket engine, fuel and a liquid oxidizer are pumped into a combustion chamber where they are burned to create a high-velocity and high-pressure stream of hot gases that provide thrust for the vehicle. To lighten the weight of the vehicle, it is being proposed that an air-breathing rocket be used. An air-breathing rocket, as its name suggests, will take in air from the Page 1 of 5
