Scramjet, together with combined cycle engines will soon allow China to fly Mach 6 hypersonic airplanes.
A new scramjet design, together with combined cycle engines, created and awarded by Professor Wang Zhengou of the National Defense Science and Technology University, could allow China to fly Mach 6 airplanes.
Hypersonic aircrafts, that could fly anywhere in the world in under 3 hours, like the American SR-72 and its Chinese counterpart, most likely will look similar to each other, due to aerodynamics lows.
“The Chinese nation is no longer satisfied with living like a farmer who eyes nothing but his own piece of land and a family to raise. We are looking up into space now.”
This schematic from a Chinese academic journal, shows plans of the proposed Chinese scramjet.
Scramjet engine:
A scramjet (supersonic combusting ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to forcefully compress the incoming air before combustion (hence ramjet), but a ramjet decelerates the air to subsonic velocities before combustion, while airflow in a scramjet is supersonic throughout the entire engine. This allows the scramjet to work efficiently at extremely high speeds: theoretical projections place the top speed of a scramjet between Mach 12 (8,400 mph; 14,000 km/h) and Mach 24 (16,000 mph; 25,000 km/h).
