How do you mean that it is better? Each propellor is selected to produce the thrust based on the RPM and Torque output of the engine. A 3 blade propell will produce more thrust than a 2 blade in most general cases. Or another way to say it is that the 3 blade propellor can turn slower than a 2 blade to produce the same amount of thrust. Also, the 2 blade propellor is easier to design and build. My experience is with Helicoper rotor blades. The earlier Bell Helicopter designs were almost entirely 2-blade "teetor rotor" design. This was much easier to design the blade attachment, i.e. the rotor grip and trunnion mount, etc. Whereas Sikorski Helicopters preferred multi-blade designs and usually odd number: 3 or 5. The multiblade design requires more precise engineering. The multiblade for helicopters have to be designed to allow movement of the blade in all 3 axis and must have a dampener for each axis. This dampener can be a rubber absorber but they usually require a hydraulic shock absorber in the axis of rotation. The point being is that it is more complicated than a 2 blade design. A 2-blade helicopter blade doesn't have dampeners because of the special requirements of helicopter designs. Therefore the 2-blade propellor IS better because it is cheaper. If you mean two props (like, say, a DC-3 or a King Air) instead of three props (like a Ford Trimotor)... two props means two engines. It means 33 percent less maintenance, because it's easier to work on two engines than three. It means if someone gets stupid and noses-over the airplane on landing you have fuselage repairs to accomplish and NOT the replacement of an engine and a prop. It means you save the weight of an engine, so your payload can be higher. It also means the pilot isn't looking through a propeller.
3 Propellers were on the famous RMS TITANIC!
no it is not
Modern warfare 3 is better
skate 3 is way better than skate 2 because better people and newer hall of meat bails i have both of the games and i gotta say skate 3 is way better than skate 2
The Titanic had 3 Propellers. The 2 side Props had 3 blades each and the Middle one had 4 blades. pinkgal333: there is a titanic 2 and 3 ok people
Yes
The Titanic had 3 propellers. She had 2 wing or outer propellers each with 3 blades and 23 feet in diameter, and 1 center propeller with 4 blades and 17 feet in diameter. All propellers were made of Bronze.
A record of 3-2 is a winning percentage of .600. A record of 2-1 is a winning percentage of .667. So 2-1 is better than 3-2.
Call of Duty Modern Warfare 3 is far better than frostbite 2 believe me...
Gears of war is better
The latest one is always better, I got an iPad 3 and it is better than my friends iPad 2
no of course not because just dance 3 you have better songs
