Controllable launcher
摘要:
A controllable launcher for propelling a payload through a predictable and repeatable trajectory to a desired height. The launcher has an energy source for propelling a carriage and a piston in substantially opposing directions and a controller for controlling the trajectory of the propelled payload to enable the payload to land gently at a safe impact distance from the edge of a destination structure.
