Alongside the growing importance that CubeSats are gaining in the space industry there is the necessity of having reliable, lightweight in-orbit deployment hardware that can be mounted on any commercial launch vehicle. The deployment of a CubeSat always occurs through the use of a mechanical system whose aim is to give a directional velocity away from the upper stage of the launch vehicle or the mothership as smoothly as possible. In this context Tyvak, a Terrain Orbital Corporation, develops a new 6U deployer which allows to significantly reduce the weight compared to its predecessors and therefore the launch costs. The CubeSat-deployer system is quite complex and it can behave differently depending on the loading conditions it is subjected to.
