Gilmour Space completes successful hybrid rocket engine test

Australian rocket company Gilmour Space Technologies achieved a hybrid rocket engine test firing with a 110-second mission duration burn of its upper stage engine. The test is a significant milestone for Gilmour Space, which is pioneering single-port hybrid propulsion rocket engines that promise to be significantly cheaper, greener and safer to operate than traditional liquid- and solid-propulsion rockets.

“We more than doubled the duration of our last 45-second test fire, and in the process proved a lot of the technologies we will need for our larger engines,” said Gilmour Space CEO and co-founder, Adam Gilmour. The Queensland-based company is developing a new three-stage hybrid propulsion rocket that will launch small satellites into orbit from 2022.

“What you see here is a mission duty cycle and throttle test of our smallest upper-stage engine,” explained Mr Gilmour, with 110 seconds being the time expected for this final stage to deliver customer payloads into their specific orbit. We also conducted a controlled throttle-down during the test to demonstrate our engine’s on-orbit manoeuvring capability to a customer.” This capability, he added, could be very useful for surface landings on the Moon or Mars.

Why it matters
Space-based technologies, previously the domain of big governments and space agencies, already provide vital services such as broadband internet, communications, GPS, and support almost every sector of the economy, including Defense.

“With space now opening up to commercial players, we are seeing an explosion of innovation in the global space industry — constellations of smaller satellites in low earth orbits transmitting massive amounts of data for our mobile needs, enabling cheaper and faster internet, autonomous vehicle systems, the Internet of Things, and much more,” he added.

“However, launch costs and availability are still big challenges for small satellite players globally, and we remain committed to providing customers with more cost-effective and reliable access to space,” said Mr Gilmour. “Our team has started to take bookings for launch, and I look forward to announcing some customer contracts in the coming months,” he added.
