French spacecraft designer and manufacturer OPUS Aerospace has selected screws from BUMAX for its new suborbital rocket and upcoming space vehicles intended for satellite deployment.

OPUS Aerospace has opted for BUMAX 88 screws to secure the two domes of a prototype cylindrical fuel tank for the Mesange suborbital rocket. The domes require high-strength screws due to their critical role in the rocket, which operates under extremely high pressure.

Specialising in the design, development, and manufacture of space launch solutions for nano-satellites, micro-satellites, mini-satellites, and small payloads, OPUS Aerospace is committed to making space access more widely available and promoting space exploration.

Safouane Benamer, CEO of Opus Aerospace, said: “We already offer our customers various space systems services and are currently conducting pilot tests for the different parts of our new fully reusable rocket. We’re planning a test launch of our Mesange rocket in early 2024, which will enable us to launch sub-orbital payloads of up to 1,000 kg and orbital payloads of 250kg. We’ll expand our capabilities gradually.”

Ignacio Amundarain, Launcher Mechanical Engineer at OPUS Aerospace, explained the choice of fasteners: “Our initial calculations showed that standard stainless-steel fasteners would not be sufficient for the loads. We have tested and validated the design of our fuel tank with BUMAX 88 on the ground with more demanding pressurisation tests than expected in normal conditions. We are confident that this will ensure the safe operation of our fuel tank.”

BUMAX 88 fasteners are known for their high strength, corrosion resistance, low-temperature tolerance, and reliability. These properties result from BUMAX's unique manufacturing processes and high-quality European steel.

Amundarain also mentioned the cost-effectiveness of BUMAX 88: “I know BUMAX’s reliability from my previous experience in designing satellites. They are also cost-effective compared to other fasteners with similar properties, and we look forward to continuing our development with BUMAX.”

Lars Holm, Managing Director of BUMAX, highlighted the widespread use of the fasteners: “Our fasteners have been used in many notable scientific projects and products, including those at CERN, on the ISS, and in the Einstein Telescope project. When the requirements are demanding and strong fasteners are needed, BUMAX is often the choice.”
