Your Sunday Morning Turboprop Noise

A quartet of CL-415s fill up on the French Rivera:

I have no idea what corrosion issues arise from operating on the ocean.

ac2usn said...: Can only guess. This is the closest water source. The aircraft can be washed and flushed after the fires are under control.

w3ski said...: Any idea of the clearance they need when doing that? I mean the distance from 'no water' to 'nose down and dead in the water'? I presume that is about a foot or so.
Just wondering.

Comrade Misfit said...: w3ski,

According to Wikipedia, six feet is the minimum water depth for the CL415.; 8/05/2018 12:25 PM
Deadstick said...: w3ski, they're not flying precisely x inches above the water with a scoop hanging down: they just land on the water, add some power, and deploy the scoop. As long as the hull is in the "on the step" condition, the drag is modest, the load is supported, and it's easy to take off again. If they should lose an engine and stop, then the hull would sink down to buoyancy level and they'd have to pump some water overboard to get back on the step.; 8/05/2018 2:56 PM
w3ski said...: Thanks, that fills out my understanding of it. I pictured them flying say 2 feet above the water.

Anonymous said...: The tanks are composite, so no worries there for corrosion. The optional foaming additive that is carried onboard in a small tank to mix with the scooped up water is corrosive anyways. If you're operating a floatplane or amphibian in salt water you wash with de-ionized water at the end of every day.

The CL415 has a system that can automatically retract the scoops when a preselected weight of water has been scooped. Unfortunately it is possible to mess up and overload the airplane which is usually no big deal, gain 3 feet of altitude and dump some water and you're good. There is a good pic of the right probe (scoop) and one of the dump doors in this report
