PDM - Panel Deployment Mechanism product range
- Start date:
The Panel Deployment mechanisms developed by SENER Aeroespacial are used in the functioning of spatial structures like thermal radiators, antenna panels and any other type of single-deployment operation that requires high torque due to elements like pipes, cables or waveguides.
Such mechanisms are currently being used in the I-Boom deployment system on the European Space Agency’s Solar Orbiter mission.
As with all its mechanisms and products focused on the commercial and telecom industry, SENER Aeroespacial implements a highly competitive, vertical integration strategy for the PDM product range. 100% of design, integration and testing work is carried out at SENER Aeroespacial facilities.
The core of the PDM mechanisms comprises four springs that are regulated by viscous dampers. The viscous dampers are secured to the mechanism by means of two flexible couplings.
This concept used on the Solar Orbiter mission is identical to that being implemented in the design of a specific adaptation (PDM-01) to this mechanism for thermal radiator deployment in commercial and telecom satellites. This product development has been partially co-financed by the European H2020 PEGASUS program and is currently at level TRL08.
