AT_airship_control_stand_(unheated) 3D Model

3D model of the AT airship control stand (unheated LTA-gas version). It was initially conceived for the AT airship. The control stand uses 3 printed circuit boards (PCB’s). The PCB1 stores a list of waypoints and directs the ship towards this using the primary control organs (rudder, motors, propeller axle motor). It DOES NOT calculate in compass correction or drift. Instead, the UMPC (model itself not integrated) constantly reads the mapped waypoints and corrects these from time to time by calculating in compass incorrection and drift (wind, current). Finally, PCB 2 is used for stopping and winching up a person aboard the airship once the button on the remote control is pushed. PCB 3 is used to measure the speed of the ascend (when no propellers are activated; ie it measures stationary buoyance/lift) and to release hydrogen if needed (if there is too much lift, there is increased friction during travel and more power is consumed by the engines).
