The objective is to develop, manufacture and test a miniaturised lightweight mechanical tilting technology suitable for thruster assemblies and to demonstrate its functional performance. The main actuation function shall be based on smart active technologies (e.g. shape memory, piezo, electroactive polymers).Targeted Improvements:mass saving by about 30% and an overall envelope reduction by about 30%Description:The increased need for agility but also simplicity of spacecraft platforms, as well as the need for controlled re-entry, requires a new approach for the thrust vectoring. This applies to the full range of spacecraft thrusters, from small thrust electric propulsion thrusters up to the larger solid motors or apogee engines. However, thrust vectoring by adding a self-standing mechanism to a self-standing thruster adds excessive mass and a synergetic design is needed, but has not yet been exploited. Smart device technologies are already existing for non-space applications and could enable an embedded thrust vector tilting technology not existing today.This activity aims to achieve a simplified, miniaturised design of a mechanical tilting technology with component multifunctionality and based on tribology-free concepts. The target tilt angle will be in the range of +/- 15 degrees (coveringthe need of +/-5 degrees for solid motors and +/-12 degrees for electric thrusters). Two breadboards will be manufactured and tested to evaluate the selected technologies, including characterisation of the deflection capability.Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl.
