Electrical vs Hydraulic flaps

[War_Emergency_Picnic]

Will there be actually any difference should you use it in high speeds?

And how does each system affect the weight of a similar aircraft?

In a high density enemy flak and bomber condition, which system is more resilient?

*high speed in this case is anything above 350 km/h

Really there's too many ways to make a system of either method to even say faster or slower. How the power is matched to the job, leverages/gearing can make either way better or worse.

But how many small to mid-size fighters then had hydraulic systems vs electric? I think that the electric wins because the plane already produces electric power for instruments. A bigger generator is less extra weight than a hydraulic system with reservoir and lines.

I would also expect hydraulics to be more work to maintain, more work to make in the first place.

But for hard work done I think that hydraulics, especially with short-run lines could be far more powerful than same-weight electric motors of the time.

Even with propellers this bears out. For different planes the solution varied. Electric for the lighter and smaller, hydraulic for the larger and heavier.

Good thing there wasn't high-bypass turbojets or pneumatic systems would also be a contender.
