One shot Rigid High Tower Model
The siphon as shown so far has simply sprayed bodies in all directions. If bodies are not released as soon as they reach the end of the tower, the tower develops a tail of tied bodies. These can be released when the overall direction of motion of the tail falls within a narrow range. In this applet, bodies are only disconnected from the tower when this happens, and the result is that once per revolution, the tail is released.
This allows the siphon to be aimed, rather than spraying bodies an all directions. It makes it into a useful mechanism not only for launching payloads, but also launching them in any required direction out from the planet equatorial plane.
Each simulation is started/stopped by clicking on the Start/Stop button. With Motion trails unticked, bodies and cables are shown at their present location. In Show trails ticked, bodies and cable motion leaves a trail. The Hold option fixes the radial distance of the lowest body in the tower. The Feed option allows bodies to be fed into the base of a rising tower. The Release option breaks the cable connecting the lowest tower body to the planet. The Shatter option breaks all cables in a tower.
Applets can be restarted by returning to this page, and then reselecting them. Where the models have randomized initialization (as in the Gravitational model and the Elastic model), a new simulation starts each time the applet begins.
The larger the number of bodies and the shorter the time interval used, the slower these simulation models run.
