He has a fascination with big things - ideas, organisations, infrastructure, achievements, brands - and the people and processes required to make them a reality. Nice article Chris. Unfortunately, as you implied, the application for this technology is going to be military in nature and will likely not be used in civilian air travel.

As a concept, the hypersonic scramjet has been around since the s, but engineers only now have the material to realise its potential as the future of air travel.
The first test flight, in , failed when the booster rocket lost control. But it was the third test that really showed the potential of scramjets. Dr Kevin Bowcutt. The XA undergoing radio frequency tests. This would make them easier to engineer, yes?
Professor Michael Smart. The XA attached to a B It increases the velocity of the exhaust gases, thereby powering the vehicle. All jet engines and gas turbines work in broadly the same way. Hence they all share five key components: an inlet, a compressor, a combustion chamber, and a turbine arranged in exactly that sequence with a driveshaft running through them.
Even though they have similarities, jet engines differ in their extra components. The main types of Jet engines based on how air is compressed in the engine are as below:.
Turbo jet engine is an air-breathing jet engine. This is one of the most common types of jet engines. It is still widely used in airplanes. Turbofans differ from the turbojets in the way they have an additional component — a fan. The fan sucks in the air and then further gets compressed and combustion takes place in the burner. Enroll Now. High-speed forward motion is used to compress the air no compressor.
Fuel is injected into the combustion chamber where it mixes with the hot compressed air and ignites. The average speed of Ramjet is Mach. But the ramjet efficiency starts to drop when the vehicle reaches hypersonic speeds. Follow this link to skip to the main content. Search Langley. Text Size. XA Flight Makes Aviation History The first and second successful hypersonic flights of a scramjet-powered airplane.
