Gilmour Space completes final Sirius rocket engine qualification test

Australian rocket engineers from Gilmour Space Technologies have successfully completed final qualification testing of its Sirius hybrid main rocket engine, paving the way for the country’s first orbital launch attempt of an Australian-made rocket next year .

The Queensland-based rocket company is developing Eris, a three-stage launch vehicle that will be a cost-effective, greener alternative to traditional liquid- and solid-propelled rockets.

“What you see here is Sirius, our primary hybrid rocket engine, five of which will propel the first and second stages of our Eris rocket into orbit in the first half of 2023,” said Adam Gilmour, CEO and co-founder of Gilmour Space. . . Sirius is a single-port hybrid rocket engine developed by Gilmour Space, which uses liquid oxidizer and proprietary solid fuel.

“As this was a final qualification test, we also tested it to destruction to help us understand the limitations of its design,” he added. Any findings will help improve the performance of future engines.

“I am happy to share that the test was a success. Our Sirius engine generated a record 115 kilonewtons (or 25,850 pounds of force) of stable and efficient combustion. (Watch it here)

“This is the most powerful rocket engine ever developed in Australia; and it met its mission duration requirement before failure,” he said.

“All engines are now qualified for our first orbital test launch next year.”
