Nefron Posted March 27, 2014 Posted March 27, 2014 When I exit a turn, and trim the Shark for level flight I usually get a lot of side slip, even though I'm not banking to either side. The indicator ball is off center, and its kinda annoying to fly that way. What gives? I understand that I should use the pedals to center the ball in turns, but I don't get why I can't seem to get rid of the slip in level flight, even if I didn't properly coordinate my turn. It sometimes happen in Mi-8 also, so I'm maybe missing some pretty basic piloting knowledge. Why does't my helicopter go the way the nose is pointing?
flanker0ne Posted March 27, 2014 Posted March 27, 2014 You should apply the wing down/top rudder method to erase the side slip, or compensate for wind, like in crosswind Take-Off and Landing where you need to mantain a straight flight path.

Bushmanni Posted March 27, 2014 Posted March 27, 2014 Helicopters fly either with side slip or slight bank at speed. Some helicopters might have taken some measures like mast tilting to eliminate this at certain speed (which varies depending on weight, altitude, etc.) but it still happens at other speeds to some extent. In single rotor choppers this is because of main rotor torque that needs to be compensated someway. In forward flight the vertical stabilator produces lift that takes over some of the load of the tailrotor but you still need a force pushing the tailboom to cancel the main rotor torque. This sideways force pushes the chopper sideways besides providing counter torque to the main rotor. If you want to eliminate the sideslip you need to fly with some bank angle. In co-axial Ka-50 it's a bit different. You can see from external view that the upper rotor is banked to the right and lower to the left and the bank angle of the lower rotor is much more than for the upper one. Rotor lift vector is orthogonal to the tip path plane which means that the sideways force of the lower rotor is stronger and hence the Ka-50 wants to sideslip to the left at forward flight. The reason why lower disk tilts more than the upper one is complicated as it's because of induced flow.
