Propeller pitch is the distance the prop moves forward in one rotation if it were moving through a soft solid. This post explains how to calculate propeller pitch and why it is important.

What is Propeller Pitch? Propeller pitch is one of the most important, yet one of the most misunderstood factors of a boat’s performance. The right prop pitch makes a world of difference on how a boat maneuvers in the water.

2019年9月27日 · The pitch of a propeller is defined as “the distance a propeller would move in one revolution if it were moving through a soft solid, like a screw through wood.” For example, a 21-pitch propeller would move forward 21 inches in one revolution.

2024年8月8日 · Compared with diameter, prop pitch has a greater effect on the boat’s performance. That’s why boaters tend to change the pitch to suit their way of boating. Essentially, adding (or subtracting) prop pitch by 1 inch will decrease (or increase) its WOT RPM by approximately 200 RPM.

2006年3月8日 · What is Propeller Pitch? By Edgar Reyes. A propeller can be defined as follows: A mechanical device formed by two or more blades that spin around a shaft and produces a propelling force in boats (or airplanes). There are several technical terms to define the propeller's characteristics such as: diameter, pitch, disc area relation, hub, bore etc.

A propeller's pitch is the theoretical distance it will move through a solid medium for one revolution. Imagine your propeller in a solid medium such that it can move through the medium, much like it would through water. For example, a 13"×16" propeller has a propeller diameter of 13 inches and a propeller pitch of 16 inches.

桨矩（prop pitch）就类似于汽车的档位，不但从使用规则上类似，从原理上也类似。 以下是各种飞行状况的桨矩使用方法： 起飞时，prop pitch要用85％～100%的prop pitch，此时螺旋桨的迎角小（不是零度，大概30度多一点），能够提供最大的静拉力。

2024年9月12日 · To calculate or refine the ideal propeller pitch for your boat, begin by assessing how your current propeller performs. Use a GPS to measure the boat’s speed and note the engine RPM at wide-open throttle (WOT). Compare this data to …

2023年9月21日 · Propeller pitch refers to the theoretical distance a propeller would travel through a solid medium in a single revolution or a complete 360-degree turn. The pitch is, in essence, the measure of a propeller’s “bite” or “grip” on the water, and …

Propeller pitch determines how far in inches the prop will travel through water for each revolution. For example, a prop with 21-inch pitch will move forward 21 inches per revolution, whereas a prop with 17-inch pitch will only move forward 17 inches per revolution.
