- The U.K. government invested $117,000 in the tech
- Autophage rockets may be used for launching small satellites
- The U.K. aims to secure 10% of the space industry by 2030
The U.K. government is investing in rockets that “eat themselves” up on the way to orbit as it scrambles to gain market share in the global space industry.
The ‘autophage’ rocket engine, developed by researchers from Ukraine and Glasgow University, Scotland, has received funding worth 90,000 pounds, or $117,000, from the Ministry of Defense’s innovation head-hunter Defense & Security Accelerator (DASA).
Autophage rockets, simply put, help to lift satellites into space by burning their own body as fuel. This tech produces enough energy to reach orbit in a smaller launch vehicle. It may help the U.K. claim a part of the global $2.8-billion small-satellite launch market, which at present is dominated by American companies Rocket Lab and SpaceX.
“The specific payloads we are targeting include the small satellites. Presently, it takes a long time to launch these because they need to be grouped for a flight on a larger rocket, which is usually launched from the U.S. or Kazakhstan. The process can take years,” Patrick Harkness, of James Watt School of Engineering, said.
The simplest solution that comes to mind for this problem is to use smaller rockets, but that is difficult because if you scale down a rocket’s size, it also reduces the amount of propellant it can carry. The rocket may not be able to reach orbit.
Autophage rockets burn the propellant and the tanks containing them, which saves excess mass and the vehicle can be miniaturized successfully.
“The body of a hybrid autophage rocket will be a tube of solid fuel, containing liquid oxidizer, which is the propellant. The entire assembly will be consumed from the
