Successful engine test brings Australian space launch capability a step closer:
An Australian research consortium has successfully tested a next generation propulsion system that could enable high-speed flight and space launch services.
The team's rotating detonation engine, or RDE, is a major technical achievement and an Australian first.
It was designed by RMIT University engineers and is being developed by a consortium led by DefendTex, with researchers from RMIT, University of Sydney and Universität der Bundeswehr in Germany.
How it works
While conventional rocket engines operate by burning fuel at constant pressure, RDEs produce thrust by rapidly detonating their propellant in a ring-shaped combustor. Once started, the engine is in a self-sustaining cycle of detonation waves that travel around the combustor at supersonic speeds greater than 2.5km a second.
Using this type of combustion has the potential to significantly increase engine efficiency and performance, with applications in rocket propulsion and high-speed airbreathing engines—similar to ramjets.
Benefits over existing engines include better fuel efficiency, simpler flight systems and a more compact engine, allowing for larger payloads and reduced launch costs.
[...] Although this technology is in its early stages, further development could support satellite launches from Australian soil and commercial opportunities for Australia's space industry, while indirectly supporting telecommunications, agriculture, transport, logistics and other industries.
