Specialist in igniters for rocket propulsion

Many of our products are pyrogen igniters. In this type of igniter solid propellant is used as a source for hot gas. The pyrogen type igniter finds its application in solid rocket motors, but also can be applied to liquid rocket engines. Since 1995 APP produces the igniters and starters for the Vulcain II engine of the Ariane 5 launcher. In 2001 we started the development of the igniters for the three solid rocket motors of the VEGA launcher. These igniters are currently also in production.

A slightly different type of igniter is the spark torch igniter. This igniter generates hot gas by combustion of a fuel (e.g. hydrogen or methane) in combination with pure oxygen. The combustion is initiated with a spark plug. The spark torch igniter is used frequently at rocket engine test facilities as, in contrary to the pyrogen igniter, this igniter can be used for more than 1 ignition. Since 1999 we are responsible for the development of the Ignition system of the Vinci engine. This engine is suitable for upper stages (e.g. Ariane 6 or VEGA) and has a unique restart capability.
