One of the most basic parts of the aircraft is its propeller. And since most of the necessary forces drive the aircraft train,design of this area requires a high accuracy. propeller have caused power generation and air circulation around the aircraft. there is a large amount of computation in the direction of the grasshopper cross – field, the propeller – fixing angle, the mode of installation of propeller on the body and so forth. Because only a small computational mistake in its design can cause plane deviation while flying or even falling. simulation of aircraft propellers and lift force calculations is one of the most important tasks that designers have been used and considered essential
