Book Description
Airplanes and airships, at the present day, often have engine installations totalling several hundred horsepower, the output from which must be transformed into thrust through the medium of one or more propellers; so that, not infrequently, a single propeller must transmit 250 to 500 HP. The peripheral speed of the propeller blades, in such cases, often exceeds 200 meters (656 feet) per second and the load due to centrifugal force may then amount to several tons. It is extremely desirable, therefore, that the strength of propellers should be calculated and not determined entirely by the workmen who are employed in their manufacture.
