This breakthrough innovation, regarded as "revolutionary," aims to propel aircraft to altitudes of 18.6 miles (30 km) and achieve speeds approximately at Mach 16. If validated, such remarkable velocity could substantially shorten intercontinental flight durations to mere hours while drastically reducing fuel consumption compared to traditional jet engines.

MUST READ 🚀 [China develops 'world's most powerful' hypersonic engine that could reach Mach 16]( This groundbreaking engine, claimed as "revolutionary," is allegedly designed by Zhang Yining and his team at the Beijing Power Machinery Institute in collaboration with the People's Liberation Army's 93160 Unit. The engine functions in two primary modes, the first being a sub-Mach 7 mode operating as a continuous rotating detonation engine (RDE). In this mode, outside air blends with fuel and ignites, generating a shock wave that travels within an annular chamber. As the rotation continues, this shock wave ignites more fuel, generating a consistent and forceful thrust for the aircraft. Despite Zhang and his team not disclosing their engine's efficiency in their research paper, previous scientific approximations suggest that nearly 80 percent of chemical energy from combustible gases could convert into kinetic energy. This marks a significant enhancement in efficiency compared to conventional turbofan engines, which typically operate at 20-30 percent efficiency and rely on slower and gentler combustion processes.

The research delves into a novel approach that examines plant behavior as a potential precursor to volcanic eruptions. A team of scientists from McGill University delved into investigating whether the well-being of plants could function as an indirect signal for volcanic activity.
