| dc.description.abstract1 | A quick ’walk-through’ of the fundamentals is made to expose the similarities of the quantum mechanic and electromagnetic approach to reach the final equation describing radiation pressure. As radiation pressure is described by these two point of view, it is explicit
that for a laser propulsion it is reasonable to work with electromagnetic approach as it
ease the manipulation of the energy transfer by the high energy laser. The orbit dynamic
of a satellite with solar sail have some particular differences in the equation of motion
because of its behaviour receiving momentum transfer from a propulsion system external
to its own body, and this require a series of force, coefficients and angle analysis. All these
three parameters are exposed and calculated as well as the laser power efficiency that will
reach the sail considering a simple ambient deviation of the beam, and these results are
used to check the available ground sites. With all necessary paramaters calculated, the
possible orbit change using 100kW laser power incidence in a sail with 32𝑚2 and satellite
weight 5𝑘𝑔 results are positive and a good amount of change are achieved using this type
of laser with the parameters given in this work. Until the date of this work a laser with
100kW power is not yet fully developed to achieve such power in the amount of time
duration needed for this application, but a 60kW laser are being produced for military
purpose and soon we will get a 100kW comercial laser. Theoretically it is feasable to use
high energy laser to change cubesats orbits parameters. | pt_BR |
