Orbex and FORCE Technology have secured a new rocket engine testing contract from the European Space Agency (ESA) to develop an X-Ray Inspection System.

The system will enable the companies to carry out non-destructive, high-energy X-Ray inspections of Orbex’s large-scale 3D-printed rocket engines – enabling them to eliminate internal flaws.

Orbex’s X-Ray inspection tech will now become a key component of future engine testing, helping to test elements of its Orbex ‘Prime’ rocket more safely.

The firm’s X-Ray Inspection System has been previously deployed to enable non-destructive inspection of strategic European launch propulsion systems. The next phase of development will see the system extended to be used with large structures, including rocket engine chambers.

It is the engineering equivalent of a medical CT scanner, revealing the details of the interior of a test item without damaging it in the process.

Commenting on the news, Orbex CEO Chris Larmour said: “Orbex is set to be the first launch operator to be able to carry out high-energy X-Ray inspection of rocket engines prior to flight, using the unique technologies and IP we are helping to develop as part of our work with the ESA.

“As we move towards series production we will use this new capability to give peace of mind to customers and assurance to licensing authorities that we have a fully comprehensive propulsion testing regime in place.”

The company is now in the fifth year of its engine testing programme, which has enabled it to generate huge amounts of data and engine testing intelligence.

Additionally, Orbex has been manufacturing 3D printed rocket engines since 2018. Its 3D printer is currently the largest high-precision metal 3D printer in use in Europe.

The Orbex Prime rocket is currently being tested on the Orbex LP1 launch platform at a facility in Kinloss, close to the Orbex headquarters in Forres, where full ‘dress rehearsals’ of launch procedures are taking place. Launches will occur from the Space Hub Sutherland.

Lars Vesth, COO, FORCE Technology, added: “FORCE Technology is constantly pushing the boundaries of what is technically possible, and operating in the space industry has enabled us to be at the forefront of technology innovation over many years.

“In the 1980s FORCE delivered inspection systems for the US space shuttle; we were awarded our first ESA contract in 2005; and – more recently – have provided technology for the Ariane 6 launcher.

“The recently signed ESA contract with Orbex will create an efficient high-energy X-ray inspection system specifically optimised for the Orbex monobody engines – and FORCE Technology looks forward to seeing our technology contribute to Orbex progressing to commercial launches.”
