There are plenty of things that you need to consider before buying propeller blades. For choosing the right and better propeller blades, you should understand everything about the type of engine and aircraft, aircraft mission function, and more than anything your goals towards comfort, efficiency, and performance.
In general, if you are searching for highly efficient propellers, then you can go for 2-blade propellers. But, for propelling the airplane, you need thrust and not efficiency. Thrust helps in overcoming weight and drag, and that result in climbing the aircraft.
There are many parameters to consider before choosing the better propeller blades and the right number of blades. The most important thing that you should consider is operating RPM, engine power, and diameter limitations. Along with this, you should also consider the performance requirements.
In case if these factors go constant, then there is a chance that the efficiency of the propeller goes down, and in that case, you should add more blades. But, when the engine power raises, there will be a need for the additional blades for efficiently utilizing the increased power. Hence the total number of blades or highly efficient number of blades needed for an aircraft usually depends on a few factors. All these factors are dependent on the aircraft itself and nothing else.
Cabin Comfort Along With Reducing Noise
There are many sources behind cockpit noise. It can be an exhaust system, engine, or it can also be from airflow around the fuselage. Sometimes even the propeller becomes the source of the noise. Sometimes the high level of noise from the cabin can stress out the pilot, and he can experience fatigue. In some cases, they even lead to hearing issues.
If you choose and utilize a single-engine aircraft, then propeller blades may result in wake beats mainly on the windshield. This usually results in producing cabin noise. If you pick the 2-blade propeller, then it may produce 2-pressure pulses for a revolution. In case if you choose three-blade propellers, then it results in smaller pulses for a revolution. Hence, it is considered that for a smoother and quieter journey, always choose a 3-blade propeller. Usually, the three-blade propeller comes in a smaller diameter.
