Variable pitch propellers and their uses in marine engineering
Introduction. Generally propellers are of two types- Fixed Pitch Propellers( FPP) and Controllable or Variable Pitch Propellers( CPP). A FPP consists of fixed. blades. This means that the position of blades cannot be changed. On the Contrary, CPP can move its blade in the desired position by changing the pitch of the blades.
All About Variable Pitch Springs
Advantages of Variable Pitch Springs. Manufacturers find a number of advantages in the ability to vary spring pitch. For example, conical springs (and other types of variable diameter springs) can be made to deflect at a linear rate.Variable pitch can also be used to prevent coils from fully closing in "soft" springs, or springs with a low spring rate.
