What are the basic parts of the propeller?
The basic parts of a propeller are the blade, shank, hub, and leading edge. The blade is an arm of the propeller from end to end.
What are the 5 sections of a propeller blade?
Basic Propeller Parts
- A. Blade Tip. The maximum reach of the blade from the center of the propeller hub.
- B. Leading Edge. That part of the blade nearest the boat, which first cuts through the water.
- C. Trailing Edge.
- D. Cup.
- E. Blade Face.
- F. Blade Back.
- G. Blade Root.
- H. Inner Hub.
What is the trailing edge of a propeller?
Trailing Edge The edge of the propeller adjacent to the aft end of the hub. When viewing the propeller from astern, this edge is closest. The trailing edge retreats from the flow when providing forward thrust.
What is the center of a propeller called?
hub
Boss This is the solid cylinder located at the centre of the propeller to which each propeller blade is attached. Boss shapes include cylindrical, conical, radius and barrelled. The centre of the boss is bored to accommodate the engine propeller shaft. In America the boss is called the hub.
What is plane of rotation of propeller?
Plane of Rotation is an imaginary plane perpendicular to the shaft. It is the plane that contains the circle in which the blades rotate. Blade Angle is formed between the face of an element and the plane of rotation. The blade angle throughout the length of the blade is not the same.
What is a CPP system?
Controllable Pitch Propellers (CPP) In Controllable or Variable Pitch Propellers (CPP), the propeller blades are attached to the boss and their pitch can be altered via a hydraulic system. The blades are removable so if they incur damage, can be repaired without removal of the whole propellor.
What are submarine propellers made of?
Material and Construction of Propeller The materials used for making marine propellers are an alloy of aluminium and stainless steel. Other popular materials used are alloys of nickel, aluminium and bronze which are 10~15 % lighter than other materials and have higher strength.
What is the blade of a propeller called?
Also called a rotor blade. ii. A rotating airfoil driven by an aircraft engine to produce a thrust force approximately in line with the longitudinal axis of the aircraft.
