What prevents those contra-rotating rotors from touching? The blades are rigid, far apart , but, most importantly, they are kept about the same distance from each other by the centrifugal force. Sometime they do touch, however. This happened with the Ka-50 when the pilot exceeded the maximum G load during testing. Ka-50 crashed and the pilot had no time to eject. Since then Kamov use a different material for the blades and moved them further apart. -- Regards, Venik Visit my site: http://www.aeronautics.ru If you need to e-mail me, please use the following subject line: ?Subject=Newsgr0ups_resp0 nse |
