"Boffins demo self-eating rocket engine in Scotland" | The Register

QuoteThe concept of a self-eating rocket is rearing its head once again as engineers showcase their work at the AIAA SciTech Forum.

Autophage engines – where the rocket effectively consumes itself – were first proposed and patented in 1938. However, it took until 2018 before boffins managed to design and fire one in a controlled manner. Nearly five years on, and more progress is being made: more energetic liquid propellants can be used, and the fuselage can be fed into the rocket without buckling.

The next step will be producing a flight vehicle, something Krzysztof Bzdyk, a postgraduate researcher at the James Watt School of Engineering, tells The Register could make a suborbital test flight as soon as 2027. Fingers crossed.

The prototype, dubbed Ouroborous-3, generated 100 newtons of thrust at the MachLab facility at Machrihanish Airbase in Scotland. The video below shows the rocket in action, demonstrating the fuselage being consumed while the rocket is throttled and pulsed. The boffins presented their paper for AIAA SciTech attendees in Orlando, Florida this week.

Have fun and keep the fire extinguisher at the ready.

I recommend ElectroBoom's YouTube channel. :smilenod:


The man is a true The Asmo when it comes to blowing up circuits in entertaining and learn-something-y ways. ;D
