- W3071838598 abstract "Directed energy propulsion—utilizing the ability of lasers to deliver energy over vast distances—has the potential to realize both rapid transit missions within the solar system, interstellar precursor missions, and true interstellar missions to other solar systems. This method of transportation proposes to use directed light energy onto a low areal density reflective foil (lightsail). The reflected beam is, based on first principle analyses, capable of accelerating spacecraft to speeds on the order of 1/4 c, where c is the speed of light. To achieve such great velocities in the near-field of the laser array necessitates very great accelerations and thus large dynamic loads being applied to the lightsail. In the case of an ideally smooth sail, the impinging light would undergo normal specular reflection, thereby ensuring the sail’s shape and directional stability, but no material is ever perfectly flat on all scales. Because of the inevitable occurrence of non-uniform loading generated by surface irregularities, it remains uncertain whether a lightsail would retain its shape and not collapse or wrinkle when experiencing the large photon pressures that would be involved in laser-driven interstellar flight. This paper studies the shape stability of the lightsail using analytic models deriving from thin plate theory and finite-element models to construct a parameter map where zones of stability and instability are delimited for the key lightsail specifications of geometry, laser flux, and material properties." @default.
