Helicopter de-icing
I'm familiar with de-icing on fixed wing aircraft, but how common is it
on helicopters and how does it work? For instance the Coast Guard flies the Jayhawk and Dauphin and I'm sure these must be certified for flight into known icing conditions. Thanks, Pete |

Just as the wing is the most critical issue with icing in an airplane it's
the same for a helicopter. The rotor is the wing of a helicopter and it would have anti-icing equipment similar to the anti-icing on an airplane prop. Additionally there is electrical anti-icing on critical areas of the airframe. As far as I know the only helicopter currently certified in the US for flight into known icing is the Super Puma, but several others are configured with anti-icing equipment.

So the rotor blades would have some type of an anti-icing "sling"
for each rotor blade? That's interesting the Super Puma is the only helicopter certified for known icing. But I guess most helicopters are flown in VFR conditions, so it's not as much of an issue. But you'd think the Coast Guard helicopters operating in a hover above water in freezing conditions would need it. Happy Holidays. "PJ Hunt" wrote in message ...

Please notice that I said "as far as I know"... there may well be others
that I'm just not aware of. I'm sure the Coast Guard H-60's have anti-icing on them as do many other helicopters. I just don't know if they're certified for 'flight into known icing conditions".

The ones I am familiar with have electric heating elements in the rotor, I
am aware of none that use systems similiar to fixed wing airplanes. A big probelm with helos is that the fusilage tends to pick up a lot of ice.
