Darchem Thermal Fabrications supplies both fabrication assemblies and insulated components (thermal & fire blankets) for a variety of aerospace Defence programmes including fixed wing and helicopters.

A developed knowledge of available materials and their performance in onerous environments is a paramount advantage as is the ability to understand the rigours of extended use whilst maintaining structural and performance integrity.  As such, material choice is an important issue. Using internal design supplemented by confirmatory testing, Darchem is able to select the most appropriate for the task and thereby not simply rely on supplier material data. This ensures Darchem developed systems fully meet customer requirements.

Example military programmes include:

  • Fighters and Trainers (Tornado, Eurofighter, F-35, Gripen, JAS39, (Hawk, Typhoon, Jaguar)
  • Transporters (A400M, KC,390, A330 MRTT, C-27J,C-130)
  • Helicopters (AW101, AW159, V280)

Product solutions include:

  • Actuation protection
  • APU fire shields
  • Bulkhead insulation
  • ECS & EBU heat shielding
  • Heat exchanger shielding
  • Fuel line fire protection
  • Pneumatic systems heat shielding
  • Power unit protection
