Front door assembly development for coronagraph instrument onboard esa’s proba-3 mission
Original language description
The paper was presented at the 19th European Space Mechanisms and Tribology Symposium organized on-line by ESA on 20th - 24th September, 2021. The Front Door Assembly (FDA) is a subsystem of the ASPIICS Coronagraph instrument developed by CSL onboard ESA’s Proba-3 mission which is devoted to the In Orbit Demonstration of precise formation flying technology which will enable two satellites to form a 144 m externally occulted coronagraph in orbit which will produce a nearly perfect eclipse of the Sun allowing to observe the corona closer to the rim than ever before. The FDA is a mechanism designed to protect the telescope optics with the capability of opening/closing the entrance aperture on the ground and during operation by rotating a lid of 134 mm diameter. This paper will describe the most important design and verification challenges along with lessons learned during a first-time development of a complex ECSS compatible space mechanism for Serenum/VZLU.
