Problems solved by technology

This patented describes various methods for simulating the movement of a space vehicle (Solar Sail) during acceleration without causing damage due to external forces like wind. However, current techniques require extensive effort and involve complex calculations involving multiple variables including temperature, altitude, orientation, and other parameters. Additionally, these simulations may only represent one aspect of the motion perpendicular to gravity, making them challenged when studying how fastly changing the pitch of the Sun relative to Earth causes change in velocity.
