A problem with helicopters.....

1,266 BreadOnButter  6.8 years ago

When a single rotor heli moves forwards, it will rotate on the roll axis as one rotor blade is hitting more air. But how does a real helicopter compensate? Any clues? My newest build has a problem with this. I know I can use gyros, but I consider them a little cheating. Also I discovered that prop engines don't have this problem.

    @EternalDarkness Thanks. A little late though. Instead I tried a contra rotating rotor instead. But I will keep that in mind.

    Real helicopters compensate for dissymmetry of lift by flappin the rotor blades. Retreating blade flaps slightly down and increases its AoA, while advancing one flaps up and decreases its AoA. It's not easy to make. In my opinion, the easiest way around it is to have rotor made out of structural panels or fuselage blocks, and have actual lift provided by a hidden jet engine.
