Ignoring how completely illogical and counter to the main benefit of using a hovercraft this question is for a second…
Given the bridge is now closed until the new year due to concerns of further damage by heavy traffic. I was wondering how much force a hovercraft would exert on the bridge deck, given it’s sitting on a cushion of air. Obviously air pressure will be exerted on the carriageway in order to provide lift, but how would that compare to the load exerted by a vehicle of similar weight?
If you drive a hovercraft halfway across, then switch it off, how does the load on the bridge deck change?
I assume this is fairly well understood by boffins out there. Would the dodgy bridge deck be effectively ‘insulated’ from the load, or would the difference/benefit be negligible.
Equasions/ridicule welcomed. 🙂
