Abstract

The usage of inflatable antennas for nanosatellites made of prepreg is considered in this paper. Antennas must have a high packing ratio and a simple reliable way of deployment. It is believed that bringing the antenna into working condition includes the process of hardening in a near-earth orbit. In this case the nanosatellite should perform a maneuver associated with a change in its orientation to the Sun. It is important for construction to exclude the unstability, which can lead to a violation of the technological regime. Folds should not appear in the unhardened construction in the process of maneuvering. Computational experiments for an inflatable antenna of the pin type in conditions when the nanosatellite makes a turn are performed. The results of the calculations showed that the lack of the folds in the inflatable antenna of the pin type can be achieved at an internal pressure respective with the value of one thousandth atmosphere. Undoubtedly the result depends on the geometric dimensions of the antenna and on the speed of maneuvering. For practical use it is possible to recommend a certainly higher pressure equal to one hundredth of the atmosphere.
