Propulsion units using solid propellants are used for instance in the field of start booster applications.

WEPA-Technologies’ developments are characterized by the preferred used of nitrate / polymer based composite propellants. Compared to state of the art double-base or ammoniumperchlo­rate based systems, handling procedures can be conducted in a much safer manner. As a consequence legal transport and storage issues are significantly less demanding and air transport can be real­ized.

Our nitrate based propellants do not contain chlorine species, therefore no highly corrosive and poisonous combustion prod­ucts containing hydrogenchloride are generated. In order to pre­vent corrosion for instance at launch infrastructure this is especially impor­tant.
