As the market for HDRM is rapidly growing with new planned constellations of satellites such as OneWeb, LEO Sat, SpaceX, Telesat and others entering the market in the next couple of years with volumes exceeding 5000 units in total these platforms are looking for a cost-effective type of mass-produced HDRM. Main requirements for Hold Down Mechanisms include: low cost of procurement in bulk quantities, extremely high reliability, proof load values up to 10 kN and scalable to higher loads, low shock during deployment. After passing the qualification process such HDRM could compete against the likes of NEA 9100 HDM and Glenair 061 in the market. Furthermore a important benefit of qualifying a European HDM would be the reduction of the dependence Europe currently has on American HDRM products from EBAD, the owner of NEA and TiNI. The overall activity objective is to develop, manufacture and test a qualification model that will have a TRL 7- of a European HDRM with emphasis on simplification of design and increase in reliability of the mechanism to be designed for LEO and GEO satellite applications. The HDRM shell be ITAR free. The modified design of the HDRM shall fulfil all requirements for such mechanism with special attention put on the simplicity of the mechanism, reducing the need for lengthyintegration procedures while retaining competitive price of the final product. In accordance with the ESA Harmonisation Dossier for Hold Down, Release, Separation and Deployment Systems as well as the outputs of the ESA Workshop on Technologies for Hold Down, Release, Separation and Deployment Mechanisms (held on 11/02/2009) the HDRM should conform to the preliminary specification. Qualification test of the mechanism shall have the scope to award the mechanism a TRL7 maturity level, hence requiring qualify the mechanism under representative space environments.
