In tests conducted, a prototype using the affordable and efficient mixture produced shocks traveling at more than 2km per second, or six times the speed of sound, the scientists claimed in a new paper published in the China Ordnance Society’s peer-reviewed“Coal powder’s high energy density, safety, and low price give it a unique advantage when used as an engine fuel,” professor Weng Chunsheng at Nanjing University of Science and Technology’s national key laboratory of transient physics who...
The new engine is expected to achieve at least a 20 percent higher fuel efficiency than modern jet engines. It does this by using extremely fast detonations that can convert more chemical energy into kinetic force. The chemical makes the ignition of a coal-powered detonation engine much easier as it ignites more efficiently than coal particles, helping to set off a chain of detonations.Weng’s team has already tested the coal-ethylene fuel mix in the complicated conditions that could arise during a flight and found the engine was able to start in almost every case and even produce rapid shock waves.
