If they turned in the same direction, torque would be generated in one direction only, thereby making it necessary for a tail rotor, Counter rotating blades blank out the torque that each other generates, THUS, NO tail rotor, thereby eliminating crashes due to tail rotor failures. But you knew that already...Hey @asj5547 ... what happens if you make the rotors turn the same direction? could you please try just to see if they actually hit each other?
It would be strange, but I wouldn't be surprised if they don't actually hit each other.
i think he meant was what happened when they crashed into each other. but in rf they won't as rf cannot detect one part of the vehicle "crashing" into another part of the same plane.If they turned in the same direction, torque would be generated in one direction only, thereby making it necessary for a tail rotor, Counter rotating blades blank out the torque that each other generates, THUS, NO tail rotor, thereby eliminating crashes due to tail rotor failures.

oooh. looks like legoman already knows how he'll handle the Flettner rotor-intermeshing challenge....but in rf they won't as rf cannot detect one part of the vehicle "crashing" into another part of the same plane.
Yeah, you`re right about that, I read into it slightly different, my first thought was about the rotors rotating in the same direction...i think he meant was what happened when they crashed into each other. but in rf they won't as rf cannot detect one part of the vehicle "crashing" into another part of the same plane.
How does RF work with a ducted fan? How does it calculate thrust & airflow? It must do something. Isn't the Fletttner a "sort-of ducted fan" with an oddly shaped duct? Does a quick bip on the throttle kick the tail over in RF like it seems to do for Trident? Or is that tail wheel vs ground friction & airspeed? I have no idea how that works, but it DOES seem to work that way. Or maybe it's just my imagination. Do you know what caused the odd sounds during/after landing in that test flight video? It sounded to me like rotors hitting something to me. Or is that my imagination, too?also there is not path for the airflow from the cooling fan to reach the rudder
Now that I REALLY think about it, I THINK I've noticed that in the back of my mind & never really analyzed it. Thanks! Do they make noise when they pass through each other? This makes me really appreciate how complex the calculations in simulations really are.When I force the rotors to collide, they do not break apart, they just pass through each other without any actual damage.
that confirms what I suspected and what legoman said: RealFlight doesn't do calculations for collisions between parts on the same vehicle; it simply allows the parts to pass through each other visually. this is no doubt so that the simulation runs more smoothly, since fewer calculations need to be made, as you alluded, Bill.When I force the rotors to collide, they do not break apart, they just pass through each other without any actual damage. Unlike if the rotors hit the ground or a building, then they break apart and stop the motor.
If the blades rotate in the same direction (both clockwise) they collide every time because the two inner blades (inclined up) are approaching each other on the inner part of the circle.
To stagger the blades I set the "Initial Azimuth degrees" to 60 for the 3 blade setup. (see pics)
