AT airship control stand heated 3D model
3D model of the AT airship control stand (heated 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). 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; ie it measures stationary buoyance/lift) and activates the burners if needed (the thermal airship is itended to continuously yet slowly descend during flight).
For the burner: depending on the airspeed more/less air enters the burners, and the pump is sped up or made to run more slowly. This ensures a 'blue flame' burning (similar to the Mekel/bunsen burner). See the 'Purchasing_the_models' link at appropedia's AT_CAD_Team for additional information on the model
