hi Gengis an others, thank you for discussing.
hi rickster, sorry, i m new here, and dint see the previous thread
here is the thread i picked from Rotaryforum
http://www.rotaryforum.com/forum/showthread.php?t=2261
as you can see it was a yes-no debate more than a finding-solutions one
you said the airfrane is designed for loads under the mast... ok, but a chute can have several strong wires drowed in the airframe and linked to the strongest part of the frame, ok it sould destroy or deform cockpit but i still thinking like Col the tail is a perfect crumple zone and while the shock, pilots and occupants are lying on their back..
i must say i m not an engineer, so sorry i m just an enthusiast
thank you all
