Aerospace Propulsion Products



APP is perfectly equipped for the production of solid composite propellant grains. In our climate controlled production facility APP has the following equipment available:

  • Mixers
  • Casting vacuum chamber
  • Curing cabinets for curing of the propellant at elevated temperatures after casting

Assembly, Inspection and Testing

Our assembly, inspection and test facilities have several rooms for assembly of igniters and gas generators. For assembly activities requiring a high cleanliness level, a class 100.000 / ISO 8 clean room is available.

A range of dedicated equipment is available for the assembly of our products:

  • Grit blasting equipment
  • Ultrasonic cleaning facility
  • Milling machine for machining propellant grains
  • TIG welding machine for welding products containing solid propellant

Facilities for inspections and testing:

  • Chemical laboratory
  • X-ray inspections
  • Ultrasonic inspections
  • Internal visual inspection by endoscope
  • Tensile testing
  • Leak and pressure testing
  • Thermal cycling
  • Penetrant Inspection

Very important for product development and product assurance during production is our firing test facility. In this facility APP can test propellant samples but also complete products. Tests can be performed at ambient, low or high temperature levels and can measure internal gas pressure, temperature, mass flow and thrust.
