Areas of Work

Small Component Manufacture

The small component manufacturing facility specialises in producing small and intricate aerospace components, e.g. the use of drills with a diameter of only 0.13 mm for producing an injector head for our 1 N thrusters. Areas of expertise includes:

• Turning of thruster nozzles for satellites including those used on the 400 N Ariane 5 attitude control system.

• Machining of coaxial injector elements, including those used on the Ariane 5 Aestus, Vinci and Vulcain 2 thrust chambers.

• Injector head erosion, as performed for the HM-7 thrust chamber and Vinci engines.

• Turning and milling of valve housings, including those used on the Ariane 5 main stage cryogenic feed valve and the cryogenic propellant isolation valve.

• Turning and milling of thrust chamber element plates, including those used on the Ariane 5 Aestus upper stage engine.

Facilities

• Sinking and wire EDM machine for sizes up to 700 x 500 x 400 mm.

• 4-5-axis lathes with two tool revolvers.

• 7-axis lathes with bar feed up to 20 mm.

• 5-axis milling machines.

• FP3 dialog II.
