This presentation will focus on MLI efficiency testing using 3D configuration (cube of various size, cyclinder), how they differ from flat MLI test (calorimeter), how they compare with the reality, at system level, and what are the main parameters driving the efficiency (size, shape, number of layers, materials...).
The ESA Solar Orbiter (SOLO) is an interdisciplinary mission to the Sun. It consists of a single spacecraft, which will orbit the Sun in a moderately elliptical orbit, using a suite of advanced Remote-Sensing and In-Situ instruments to perform a detailed observation of the Sun and surrounding space. Due to the nature of the mission, the spacecraft will get as close as 0.28 AU from the sun,...
The contact conductance of copper based brush thermal connections were investigated. Results show a significant increase in heat transfer as compared to purely radiative connections during a cool down from +20 °C to -180 °C. Derived contact conductance values are higher than for common slip-rings or ball bearings.
Two possible applications initiated the interest for copper based brushes....
The SAOCOM satellites (1A and 1B) are two twin L-band SAR satellites for earth observation. Each satellite weights 3.000kg and main dimensions are 10m wingspan and 3.5m high.
This program is developed by the Argentine Space Agency CONAE as a customer and INVAP as Prime Contractor.
SAOCOM 1A was successfully launched in October 2018 and then began its observation and acquisition phase. Both...
The presentation deals with the design, function and qualification process of a thermally activated separation bracket. This new principle was developed for Sentinel-1 C&D in order to support the satellites demise and thus avoid satellite parts hitting the ground after re-entry.
The principle is based on a soldered cup-cone fixation between antenna and bus. During re-entry, as soon as a...
