may i know the other term of propeller blade particular in ship propeller There is no alternative term for "propeller blade", but the entire prop is sometimes called a screw.
propeller
It is called a rotor, and it more closely resembles a wing than a propeller blade
Propeller or the prop. In a jet plane the it's called a turbine
A damaged propeller (e.g. with a blade or part of a blade missing) will "move water" less efficiently.
The best "angle of attack" for a propeller depends on many factors, the main ones being: the speed of airflow over the blade; the distance along the blade from the centre of revolution; the physical dimensions of the blade; the density of the air which it is trying to pull, or to push, to produce the force called "thrust" which drives the blade, and the aircraft attached to it, through the air. That is why the blade does not have a simple flat surface, but one which has many angles of attack along the blade due to the complicated shape of the blade.
It is possible to replace one kind of propeller (sometimes called a screw) with another kind. When moving to the "less complex" two blade propeller, the mechanisms that control the pitch of the blades of the propeller with pitch control will be abandoned or removed. There may be a lot more to this, but the basic answer is that you can replace one kind of propeller with another kind, as long as the "handedness" of the screw is the same as the one coming off. Or you'll go backwards in "Ahead" and ahead in "Back" on the direction selector.
Two bronze triple-blade wing propellers. One bronze quadruple-blade centre propeller.
The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.
The Twisted blade that helps a plane fly and a ship move is call a propeller.
Propellers are measured in stations. This is done by first finding the propeller station number where the angle measurements are taken. Stations are measured in inches from the center of the propeller hub. As an example; propeller station 35 would be 35 inches from the center of the hub. The propeller maintenance manual and/or the Type Certificate Data Sheet for the specific propeller will provide the station number. Once you have located the proper station a propeller protractor is used to measure the angle. The protractor must first be "zeroed" (normally at the hub). Then the angle will be checked on the "Face" of the blade (this is the side that "faces" the pilot when sitting in the pilot seat). This must be done on each blade of the propeller to ensure they are all the same (or within limitations set by the manufacturer).
The 150 and 152 both have 2 blade propellers.
