Realizing this, sanderson and archer proposed a new theory based on an adaptation of the prandtl–betz–theodorsen theory of heavily loaded airscrews for the design of propeller wind turbines which are to be optimized for maximum power output.
In aeronautics, a propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards.

In 1898 he read his exhaustive paper on kites in theory and practice. Always a close student of the possibilities of heavier-than-air flight, in march, 1904, he read a paper on experiments with aerial screw propellers, after having carried out 350 tests on various types of airscrews.

Nonlinear aerodynamics theory is used to analyze the blade force. A mathematical model of fan blade noise is developed and simulated by the precision gauss-legendre method. The model simulation and the experiment results are analyzed in the frequency domain. The simulation results are in reasonable agreement with the measured data.
Thevortex theory and observations of overall thrust and torque on the familyof airscrews, except for the screws of the highest pitch diameter ratio, forwhichthe torque is calculated too high over the whole working range, the thrust too high except ncar zero thrust,.
As the airscrew moves forward, the volume of air delivered and the thrust exerted decrease, and at a certain speed become nothing. At this forward speed the distance moved in one complete revolution is known as the experimental pitch of the airscrew.
In this pioneering account, a distinguished aeronautical scientist presents a history of fluid mechanics focusing on the achievements of the pioneering scientists and thinkers whose inspirations and experiments lay behind the evolution of such disparate devices as irrigation lifts, ocean liners, windmills, fireworks and spacecraft.
The blade element momentum (bem) theory is a model used the fundamental quantities of this model are two experimental coefficients ( usually denoted by the elements of aerofoil and airscrew theory.
The difference between the theoretical pitch and the effective pitch is called the in this experiment, we will examine propeller characteristics in a subsonic wind.
The thrust and torque forces as computed by means of the theory are therefore greater for the elements near the tip than those found by experiment. [7] in order to eliminate scale effect, the wind tunnel tests on model wings should be run at the same value of reynolds number (scale) as the corresponding elements in the propeller blades.
