This application is a continuation in part of my application filed May 1, 1943, Serial Number 485,285 now abandoned, and relates to adjustable pitch aeroplane propellers and specifically it refers to propellers which are automatically ladjustable by means of the resultant force of the thrust......
What is a propeller? A propeller is an aerodynamic device that converts rotational energy into force. This force propels the airplane forward. This creates thrust that is perpendicular to its plane of rotation. Propellers have two or more blades. Propeller blades are spaced evenly around the hub...
In the description of the airplane's Propeller, the propeller and its operation if pitch can be varied shall be deseribed. A. 描述飞机螺旋桨时,如果桨距可变,应描述螺旋桨及调距操作。 B. 描述飞机螺旋桨时,如果桨叶间隔可变,应描述螺旋桨及其操作。 C. 描述飞机螺旋桨时,如果桨叶迎角可变,应描述螺旋...
METHOD AND APPARATUS FOR ADJUSTING PROPELLER BLADES OF A HYDRAULICALLY CONTROLLED VARIABLE PITCH PROPELLER METHOD AND APPARATUS FOR ADJUSTING PROPELLER BLADES OF A HYDRAULICALLY CONTROLLED VARIABLE PITCH PROPELLERAn adjustment device comprises a control slide (13) proportionally adjusted as a function of the...
This invention has reference to propeller blade .pitch measuring devices for propeller blades mounted on air craft or other vehicles. It is frequently necessary in airplane factories and on the flying field, to check the pitch of propeller blades, especially in the variableThi b- h 1 heretopit...
did the engine exceed 2,550 revolutions a minute, its normal rated speed in level flight. Hence, he explained, the strain on the motor during the dive was not increased, but was held to the speed of normal operation by the Curtiss electric propeller, with its unlimited blade pitch range....

During flight electric motors can consume large amounts of energy, while most of this energy is transformed into spinning the propeller, a portion of it turns into heat. This heat must be dissipated, and therefore airflow must be maintained over the power system, ie the motor, battery, and...
