Variable Lift Control of a Space Vehicle During the Re-Entry into Martian Atmosphere


Ohtakay, Hiroshi (1969) Variable Lift Control of a Space Vehicle During the Re-Entry into Martian Atmosphere. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/NAF8-Q357.


Re-entry trajectory design problem of a space capsule into the Martian atmosphere is investigated within the context of modern control theory. The optimal control law which minimizes the heat generated on the surface of the capsule is obtained analytically. This in turn allows the capsule to make a successful softlanding on Mars through the partially known atmosphere of the planet. The investigation is also extended to the guidance of the capsule in a stochastic disturbance environment. An attempt is made to simplify the stochastic control law so that the mechanization of the resulting control law is within the grasp of current engineering technology.
