Chinese researchers aim to drastically reduce the cost of hypersonic flight with a new type of engine. It should be used with a combination of ethene et carbon powder. One study conducted soil tests of the mixture, which created shock waves that erupted in the 6 times the speed of sound moved. The reports that South China Morning Post (SCMP).
“The high energy density, safety and low price of powdered charcoal give it a unique advantage when used as fuel,” said the team, led by Weng Chunsheng au Nanjing University of Science and Technology. Scientists are developing an engine that will allow long-haul flights at a speed of faire 7 should allow.
Feature
The experimental coal engine uses explosions to generate thrust. be there fine carbon particles, which are not the size of bacteria, are blown into a chamber filled with oxygen. There they are ignited by a spark. The detonation compresses the air, triggering even more explosions thrust produce. According to the team, the biggest challenge is to trigger the process in a controlled way. This is where ethene comes in. This ignites more easily than carbon particles and mixes with them.
The team expects the new powertrain to have at least one 20% more energy efficiency achieved than current modern jet engines. The research team came up with the idea Explosions in coal minesfeared for their destructive power.
Russia and the United States
The idea of using coal as fuel for hypersonic flight was proposed 10 years ago by the Russian Academy of Sciences developed for the first time. At that time, you mixed carbon powder with hydrogen. The US military is also studying hypersonic aircraft and related engines.
