EnglishAurora spacecraft is a scientific probe propelled by a “fast” solar sail whose first goal is to perform a technology assessment mission. The main characteristic of the sail is its low mass, which implies the absence of a plastic backing of the aluminum film and the lightness of the whole structure. In previous structural studies the limiting factor has been shown to be the elastic stability of a number of structural members subject to compressive loads. An alternative structural layout is here suggested: an inflatable beam, which is kept pressurized also after the deployment, relieves all compressive stresses, allowing a very simple configuration and a straightforward deployment procedure. However, as the mission profile requires a trajectory passing close to the Sun, a configuration different from the ‘parachute’ sail proposed in another paper, must be used.
