Date of Defense 1961-07-05 Availability restricted AbstractA logarithmic spiral trajectory is not the optimum trajectory
for a solar sailing space vehicle. Investigation of the governing
equations showed that the performance of the solar sail depends on
one parameter "a". This parameter "a", defined simply as the
ratio of radial to tangential forces, was seen to be significant
for two reasons: first, the logarithmic spiral is restricted to
values of a == 2√2
; secondly, decreased values of "a"
indicate better performance characteristics. For values of
a < 2√2 E a new trajectory was generated and found to be more
efficient than any logarithmic spiral trajectory.
