Just because you replaced 1 thing with 2 things doesn't mean you've increased the system's reliability. In this case, you've also added a lot of complexity in the shafts, seals, and gearboxes. That means more things that can go wrong. Most of those things can affect both screws when they fail, so there isn't any gain in reliability due to redundancy at all. |
