I have tried blades that look very similar in profile yet fly completely different. I would like to know what attributes are responsible for the following:
Bite: what shapes determine how aggressive a helicopter blade creates lift. I know airfoil can have something to do with this but some airfoils are more toward the center line of the blade while others are at the leading edge.
Stability: What characteristic determines how stable the helicopter is at fast forward flight. For example I know that Halos are pretty good at FF flight, and so are rails.
maneuverability: Some blades roll and flip really well. Others not so well. I am guessing the COG of the blade weight has something to do with this.
Bigger blades vs Smaller blades on the same helicopter: I dont know why but i am drawn to the biggest possible blade that will fit on a helicopter. It just "FEELS" beter to me..
Efficiency: What charactoristics make a blade more efficient? Ie: is a particular profile airfoil more suited towards a certain RPM? Some blades mange to provide pop without draining the engine.
Outer Edge Profile: Does the shape of the outer edge have a big effect?
All these questions remain unanswered in my head... Does anyone know the answer to some of these questions? Do we have an aeronautical engineer in the house?
