General aviation aircraft generally uses the piston engines and propellers as its power plant.The performance calculation of the propeller is of great significance in the phase of the plane design.Based on the standard strip analysis,this paper presents a numerical procedure,and carries on the calcul...
If for a boat, set prop pitch to limit engine rpm to or just under engine redline rpm when on plane (or as fast as the boat can go) in smooth, calm waters . Obviously you will need a tachometer connected to your engine. This procedure applies to ALL engines at or just under engine...
Adjustable propellers are those which have a hub containing two or more blades which may be adjusted when the plane is on the ground. The adjusting is done by loosening the fastening of the blade and simply rotating them to a different angle. This kind of propeller can be used in several ...
