Scottish-based company reveals 3D printed liquid bi-propellant rocket engine


Skyrora, a pioneering space launch company, has unveiled its newly built 3D printed 30kN (kilonewton) liquid bi-propellant rocket engine. This ground-breaking engine technology was assembled over a period of 2-3 months and was precision welded at Skyrora’s production facility in Scotland.

 

The innovative engine produces 3-tonnes thrust, which makes it one of the largest rocket engines ever to be developed in the UK. The new 3-tonne engine has been constructed using additive manufacturing techniques and advanced materials, including Inconel. The engine utilises a regenerative cooling approach and has Thrust Vector Control (TVC) built in.

 

 

 

The method used to 3D print the engine was completed by ‘powder bed fusion’, where a laser is used to melt and fuse the metal powder together. 3D printing was chosen by Skyrora as it increases the accuracy of the components, drastically reduces part count, decreases manufacturing complexity and reduces the cost of the engine build significantly.

 

Final assembly and precision tungsten inert gas (TIG) welding was completed at Skyrora’s production facility in Loanhead, Scotland, close to the company’s HQ in Scotland’s capital, Edinburgh. The 3-tonne engine will be used in Skyrora’s commercial sub-orbital vehicle Skylark-L which is expected to be ready for launch by Q2 2020. The company plans to start testing this engine in Scotland in Q1 2020.
