University of Sydney’s School of Aerospace, Mechanical and Mechatronic Engineering is way too close to the development of an economical and efficient entry to space platform for the launch of satellite as it’s combustion experts, as part of their research project, along with the Associate professor Matthew Cleary, Ben Thomber and Dr. Dries Verstraete have united with the goal of developing the very first successful engine with rotating detonation that forwards payloads into the space.
The project was granted $3M CRC-P as an investment into the space industry of Australia. Researchers from different universities took part in this project.
Group of the Associate Professor Cleary has directed its focus of research on combustion and has started simulations of computational fluid dynamics, with early results indicating the effectiveness of the revolving detonation engine. Three aerospace engineering researchers are also included in the group who are currently working on the performance of rotating detonation cycle.
The Associate Professor Cleary described that “Since the project kicked off we have worked with our collaborators to develop new computational methods to investigate supersonic combustion, which is a process known as detonation.”
Moreover, he said that “Our preliminary findings from simulations of a model rotating detonation engine have led to some interesting findings about the stability of detonations in an annular channel, in particular with regard to the importance of designing the combustor geometry such that the detonation is stable and rocket thrust can be sustained continuously. This information is being fed to our collaborators who are now starting work on ground testing an engine.”
The associate professor went on to add: “While conventional rockets carry both oxygen and fuel onboard, the team has been researching methods for rockets to effectively collect oxygen from the atmosphere during lower atmospheric ascent. What’s exciting about rotating detonation engines is the potential to operate them in a so-called “air breathing” mode. The purpose of this function is to reduce the mass of the launch vehicle and increase efficiency, reduce costs, and potentially allow for larger payloads, such as satellites.”
To examine the air breathing function of the engine, Professor Christian will be performing simulations.
“The propulsion concept of the rotating detonation engine is very promising for the future because of its cycle advantages — we are very glad to be part of this important research
