Abstract
This document contains the design of a solar sail. Three main parts will be
studied in this project: structural design, thermal design and deployment
.
The first one will be based in studying the different materials that can be used
nowadays to build a solar sail, they will be compared and finally, one will be
chosen. The loads on the sail will be also evaluated and the place of all the
components too
;
the components
that will be on the film and the ones that will
be placed on the main structure, always taking into account the different
interactions that
will
exist between them and the assembly requirements.
The second one
will study the thermal equili
brium. This equilibrium is based on
computing not only the temperature reached on the film, also th
e temperature
reached at all those
components
exposed to the Sun. Once the result will be
found, some changes will be done in order to accomplish the functio
nal
requirements listed by the mentioned components.
On the other hand, the different types of deployment will be evaluated an
compared. Finally one of them will be selected according to the characteristics
that our project needs. At the same time, this
deployment mechanism will add
more components that will be studied in the first chapter.
The final result will be a solar sail that, even though the efforts
made
to reduce
the
global mass, is heavier than 100
grams so, the conclusion will be that
nowadays
it is impossible to build
this
kind of spacecraft.
However, the possibility of a solar sail completely func
t
ional
, spending long time
periods in mission (analyzing the magnetic camp)
will be ratified
.
The project will end with a built and deployed sola
r sail which will be composed
for a thin film of Mylar (at 44ºC) with two coatings; one of aluminum and the
other of chromium. The deployment system that is going to be chosen is the
one that uses the inertia of the Booms to deploy the sail, avoiding any k
ind of
extreme loads
