In a discovery, researchers have developed and tested a self-eating rocket engine. This engine will be consuming the structure of the rocket to launch small satellites like CubeSats, and it will cost less, and it will also not add any pressing problem of space debris.
In the recent launches, every rocket depends on the power of the rocket. The rocket gets the power from the propellant or from fuel which is loaded in the large amounts into the tanks of the rocket which is present in the vehicle. It takes the vehicle to orbital speeds and delivers the payload, but on most of the time, the weight of the propellant is higher than that of the payload which was present in the rocket.
According to the Patrick Harkness, who is the lead researcher in this work said, “Launch vehicles tend to be large because you need a large amount of propellant to reach space. If you try to scale down, the volume of propellant falls more quickly than the mass of the structure, so there is a limit to how small you can go.”
The new autophagy rocket engine which is designed by engineers from Glasgow University, Scotland and OlesHonchar Dnipro National University, Ukraine, offers the best way to scale the things down and helps in making free-up the space for cargo. As per the release from Glasgow University, it states that the engine will be consuming a propellant rod which will have solid fuel on the outside and powdered oxidiser on the inside. This rod will act as a body of the rocket, and it will take the rocket. This results in both the fuel and the oxidiser will be vaporised into the gases, and it will move into the rocket’s combustion chamber, and it will provide thrust to the rocket and the required amount of heat.
