Project 2023
 

Creating a bi-liquid rocket

Each year, we design, build, test and launch a high-powered rocket. In the last two years we have been in the forefront of student rocketry in the world, competing with solid motor rockets. Building on that experience, we are now going bigger…

 

For Project 2023, Propulse will design, produce, test and launch our first ever rocket with a bi-propellant liquid engine. This is an ambitious undertaking which requires a multitude of skills covering almost all disciplines of engineering. 

 

Below you can read more about the engine development, but you can also read about the other systems on the application page.

Our rocket engine

This year's engine development group has the main objective of designing, producing and testing our first ever liquid rocket engine. It needs to be capable of achieving over 3kN of thrust and propell the rocket up to 3 km above the ground. The engine will be completely researched and developed in-house and will act as a foundation for future R&D as well as projects.

Combustion chamber

The combustion chamber is where the fuel and oxidizer is mixed and combusted in the engine. The chamber needs to inject and burn almost 2.5 kg propellant per second, without overheating or becoming unstable. The system consists of a burn chamber, an injector plate and an exit nozzle where the hot gases exit, providing thrust. 
 

The chamber is the most complex part of the entire rocket, as the combustion process results within the chamber are challenging to predict and can often only be validated through testing.
