Bar Fin

Bar Fin
What does that bar with fins at the end do on a helicopter.?

im talkin about the one thats connected to the main big blades on top of the helicopter.

The short answer is; it prevents the helicopter from spinning. The long answer is quite long and probably more than you are interested in at this point.

I did some aircraft accident investigation in one of my jobs and we had to know how an aircraft operated to make any attempt at explaining why it crashed.

Oh yeah, there is a site on the web that explains how things work. Try the site listed below. If you still don't understand, contact me through my profile, send your email address and I will try to explain all the whys of the tail rotor to you.

    I’m curious to find out what blog system you are working with? I’m having some minor security issues with my latest blog and I’d like to find something more risk-free. Do you have any recommendations?
