Westland WS-61 Sea King MK.41 89+60 Deutsche Marine | Hamburg Hafengeburtstag 2014
Flying a SAR Demo at the Hamburg Hafengeburtstag. Notice the loadmaster hanging on to the door frame, a person filming the display with a smartphone through the bubble window.
For the viewers with an engineering background, there are wrinkles in the tail boom skin panels. This is visual evidence of local buckling, as the load bearing skin panels are subjected to torsion loads and lose stability. The structure is designed to do that for weight-saving purposes and retains global stability. The increased loads come are induced by the tail rotor pushing on the structure during the left hand turn. Because the tail rotor axis is offset versus the tail boom axis, there is a moment associated with the pushing force, thus leading to torsion loads in the skin panels.
