WebTherefore, the opposing viscous force which acts upwards also goes on increasing. Finally, a stage is reached at which the weight of the ball is just equal to the sum of upthrust due to buoyancy and viscous force. In such a condition, the net force acting on a body is zero and it starts falling with constant velocity (terminal velocity). WebThis paper presents an impact-angle-control guidance law with terminal constraints on the curvature of the missile trajectory. The formulation takes into account nonlinear kinematics and time-varying velocity, allowing for more general cases in which the flight path angle may not be small throughout the entire trajectory. The proposed optimal guidance law …
