Copter | Maximizing Torque Efficiency for Multiple Generators

[kitarey]

I am not looking for a detailed answer to this question just a general.

Say that you have 4 generators placed one above the other, and they are spaced 4 ft apart (not significant). You have a vertical roller chain (think of a bicycle chain) that all 4 geared shafts are "attached to", all rotating off the single chain. Say that each generator shaft requires 10 ft lbs of torque to rotate. If you pulled on the chain, with the chain rotating all four generator shafts, approx what ft lb force is needed on the chain? It is not 10 x 4, but I am sure that it is not 10 either. It is 10 ft lb plus a factor of something for each additional shaft right?

No, the total torque demand is the sum of the individuals. In your example, the torque applied to the chain to drive all four generators would be 40ft-lbs plus a bit for frictional losses in the drive system.

, this is an interesting question that highlights the importance of torque efficiency in a multi-generator system. In this scenario, the total force required on the chain will indeed be more than 10 ft lbs due to the added factor for each additional generator shaft. The exact calculation would depend on the specifics of the system, such as the gear ratios and the efficiency of the chain. However, in order to maximize torque efficiency, it would be important to consider factors such as the weight and placement of the generators, as well as the strength and durability of the chain. Additionally, carefully designing the gear ratios and minimizing friction in the system can also contribute to maximizing torque efficiency. Overall, this is a complex problem that requires careful consideration and optimization in order to achieve the most efficient use of torque in a multi-generator system.
