It is encouraged to use off the shelf components, rather than design everything from scratch. I have done research and found applications of using a syringe, RCABS, peristaltic pumps to simulate a buoyancy engine. However, I have having difficulty finding a fully commercial one available, only a model from Arkmodels.
Note it doesn't have to be super complex - it is only going up and down so no complex ballast system is needed! It just should be reliable and ideally have a failsafe mechanism. Can anyone help me point me in the right direction of a commercially available buoyancy engine, or possibly at least one that would require minimal parts to supply?
Thanks
Although I've never been involved with model submarines, your challenge sounds intriguing.
My approach to your problem would be to go with simplicity and the simplest system that I can think of is one that is primary comprised of a compressed air tank (for power) and an air bladder.
For control, 2 valves can be used, one to supply compressed air from the tank to the bladder (to ascend) and another one that would release air from the bladder (to dive).
I don't know what criteria your failsafe system would have to meet so I'll leave that to your imagination.
