Three common types of RC props used where I fly are wooden, carbon-reinforced nylon (APC brand), and fiberglass-reinforced nylon (Master Airscrew Brand). This chart represents average prop usage and should used only as a general guideline. If the prop did not slip at all as it screws through the water, each rev theoretically propels the boat the forward a distance equal to the prop pitch. Propellers for glow and gas powered airplane models. It has a section devoted to matching propellers to RC glow engines. Going a little farther, we can actually set up a speed trial to determine how fast an aircraft is going and then determine propeller efficiency using those numbers (time over distance). For example constant speed props typically achieve 10% better efficiency than fixed pitch. High Altitude Research Airplane Grob Strato 2c with MT-Propeller To make such a prop rigid will require a thicker blade (heavier and more expensive to produce), which in turn operate at lower rpm (due to absorbing more power), and reduce the propellers overall efficiency. Recommended prop ranges will vary depending on your particular engine and airplane. Learn More Automating RC Motor Efficiency Testing. Its excellent air dynamic design greatly improves efficiency.

The highest propulsion efficiency is possible with a large, slow-spinning prop. 0) Glass Fiber Nylon Prop comes Epoxy resin cover. One of the main decisions is whether or not the aircraft designer is willing to build an aircraft with a propeller which rotates in the "wrong" (for American aircraft, but "right" for European aircraft) direction. Here is some calculators about RPM&Thrust&load weight and a simple example of its applications are given,if you want to know please go ahead. Choosing the Right Propeller Choosing the right prop for an application is the hardest selection. They are not intended to perform complex cavitation or efficiency calculations. Lightweight molded nylon construction reduces rotating mass for less drag and more efficiency. We have found that there is a significant reduction in the noise levels in the cabin and outside the aircraft. If a propeller of diameter, d, delivers the thrust, T, while the plane travels at the speed, V, it always has a maximum possible efficiency that can be calculated, is below 1 and can not be improved.
