GE Aerospace says it successfully demonstrated an advanced jet propulsion concept that involves a dual-mode ramjet design utilizing rotating detonation combustion. This could offer a pathway to the ...

A.At the risk of oversimplification, here is the relationship between cylinder pressure conditions and time in a normal combustion process vs. detonation. Note that the rate of pressure rise vs. time ...

Detonation is probably a hot rodder's worst enemy. It's also been called ping, the death rattle, or just plain spark knock, but by whatever name, detonation is a big killer. When you hear a noise that ...

Tsinghua researchers combine ramjet-based rotor compressor with a detonation engine which they say advances propulsion technology Chinese scientists proposing a new concept for a hypersonic engine ...

Type Ia supernovae are critical tools in astronomy, since they all appear to explode with the same intensity, allowing us to use their brightness as a measure of distance. The distance measures ...

WASHINGTON, July 2 (Reuters) - The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its ...

For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the centuries-old remains of supernova SNR 0509-67.5 with the European Southern ...
