Answers:
On average what is the cost to completely fuel a 747 airplane with full tank of fuel?
........................ you can have smaller radius of propeller ar with 3 blades for same thrust ........... whereas the 2 blade propeller requires longer thus larger radius for the same thrust .............. smaller radius are more desirable as a design ..............Any one need an IL76 charter ?
A three bladed propeller creates more thrust then a two blade propeller.Experiments...any suggestions plz?
A two blade prop is more efficient, uses less power, and will give more speed. A three blade gives more thrust.What if I need to cancel my flight?
I disagree with the above.I want to become a Commercial Pilot but my financial health is poor?
A 3-blade prop produces the same thrust as a 2-blade at the same RPM. The advantages are that it's quieter and keeps its balance longer.
why do you not apply brakes while weighing a plane?
3 bladed propellers are more efficient, they have more "lift" surface area than 2.2 bladed propellers are more cost effective (cheaper) and have less rotational mass that make it easier on low power small airplanes. Example, a Piper Tomahawk only puts out around 100hp so 3 blades would be too much rotational mass for it to effectively power.
Also the more blades you have, the more drag they induce. The more surface area caused by more blades also creates drag as the airplane moves through air and the on coming air collides with the blades. This is why aircraft do not generally have more than 4 blades per propeller.
