What Purpose Of Rotor Head Dome In Helicopter?

[Brandon Chng]

no worries, we're all here for knowledge, no one can know everything

the lightning thing is very interesting...are there any websites where one can read up more?

i would think aerodynamics may be a big part of it. the rotor grips and hub are like spokes of a bicycle wheel, which create turbulence when in forward, even slowly speeds, because the rotor rpm is still high. just like speed bikes have solid wheels to cover the spokes, i would think the same thing about the rotor heads

I just watched "Air Crash Investigation" on National Geographic Channel.

It is about a Super Puma (56 Charlie of Bristol for transporting oil rig worker) crash into the middle of ocean (near British)

The cause of the crash was due to lightning strike onto the tail rotor blades (Carbon fiber blades)

BTW, Super Puma also has the dome on top of the rotor head.

i watched that too.... but fell aslp halfway

did anyone die?

[Super-Hornet]

No one die. If u want to watch it again, do take note on the repeated telecast.

Hi,

If you are refering to the dome on top of the main rotor blade, it is just a cover to prevent water from entering the inside of main rotor head. For those on the apache, it is a radar or eye.

ah.. finally the correct answer.

Maybe Navi can tell us a bit about yourself...then people will 'fu' the answer

Back to the original topic,

I spoke to a super puma engineer. The so call dome, they call it umbrella is nothing more than a cover, there is a hydraulic vent below.

Super Hornet

Here are a few more other heli that has similar dome.

As for U.S. Heli with dome, not only U.S. heli has it.. Sea King, Lynx (both British Heli), Eurocopter also have it.

u post soo mach pictures soo nice
