WIPERs

[oceancrosser]

Mazda did that with the rear window wiper on my RX-7 30 years ago to reduce noise and drag.
I'm somewhat surprised it's taken the aircraft manufactures this long to catch up

No matter how cheap a car you buy, the wipers are far better than on any airliner I have flown. 757/767 wipers. Crap. And lots of times they will not stop when switched off.

The first aircraft I flew that had pretty good wipers was the 747-400. At leaast that was my experience. The 777 seems pretty good as well and someone decided to give us a nice intermittent mode. All the truboprops and old Boeings were crap.

In my experience (CRJ, E170/175, A320) they produce more noise than benefit.

Didn't the CV880 /990 use bleed air for rain removal ?


I imagine that was noisy but effective.

That squirty stuff in the 146 ran rings around the wipers.

I must admit the Saab has good wiper blades except the speed choices.. off, super fast or having a seizure bat**** crazy fast.

Same here on my non-SAAB!

Never flown any aeroplane where the Wipers actually worked! From GA to multi-million dollar aeroplanes! Just sayin!

DC-8s did have bleed (from the compressors in the nose) for rain removal. Fairly effective, but noisy as hell.

The bloke who designed the wipers for the Dash 8 Q400 must have been told at 1658 on Friday "bugger, we forgot the wipers. Quick design something".

The Q400 wipers are identical to the 'Classic' Dash.

Our outfit they usually try and stop the wipers when they are kind of vertical. Reduces noise considerably.

Still look like they are having a seizure when they are operating

Many aircraft don't even have wipers. I know that some use a rain-dispersant coating on the 'glazing', so if that works why go to the trouble of fitting wipers in the first place?
