Australia’s hypersonic ‘spaceplane’ to launch tiny satellites

In central Sydney, a hypersonic ‘spaceplane’ is being constructed, but the passengers will be gadgets rather than people.

Delta Velos is a streamlined spacecraft that will launch tiny satellites into orbit using four green-hydrogen scramjet engines.

Engineer Simon Ringer and his colleagues at the University of Sydney are working on a zero-emissions spaceplane alongside Hypersonix Launch Systems, an Australian aerospace engineering business.

Professor Ringer told AAP on Thursday that “there will be this Australian-made vehicle that is really a complete leap in technology, travelling at hypersonic speeds.”

Objects have gone from fun and quirky to industrial and functional because to the invention of powerful 3D printers, often known as additive manufacturing tools.

Flight-critical sections of the spaceplane, which will be propelled by the world’s first 3D printed scramjet engine, will be made using additive manufacturing.

Prof Ringer explained, “You may abruptly pull items off the blueprint and off the design sheet.”

“In 3D, we can create shapes and designs that we couldn’t previously. You have complete freedom to let your imagination go wild.”

When you add in the ability to imagine and combine new alloys, the project takes a huge step forward.

“This is a completely new approach to the production of metallurgical materials. It’s not the same as a foundry, and it’s not the same as what happens at a steel mill “he stated

“All of a sudden, we’re looking at combinations of elements that can come together in a novel method, and many of them have extraordinary features like high-temperature strength,” says the researcher.

Both characteristics can be explored at the University of Sydney’s Darlington campus’ manufacturing base in the engineering precinct.

Before moving forward with the larger version, Hypersonix will create a succession of smaller proof-of-concept cars.

The first of these experiments will be propelled by a 500-kilometer-range scramjet engine that might also be utilised as a hypersonic target drone.

According to Hypersonix managing director David Waterhouse, the only emissions will be water vapour.

In early 2023, he plans to unveil a three-metre long DART AE demonstration as the world’s first 3D print of a full hypersonic platform in high-temperature alloys.

It might be the start of a long list of projects for Professor Ringer and his team.

“Our objective for the Sydney manufacturing centre is for firms like Hypersonix to come in and work with us, to play around with additive manufacturing and learn how to deploy this great scientific and technological disruption,” Prof Ringer said.

“We’d like to be a sandbox for Australian businesses.”
