Variable Pitch Propellers

Description: In this report are described four different types of propellers which appeared at widely separated dates, but which were exhibited together at the last Salon de l'Aeronautique. The four propellers are the Chaviere variable pitch propeller, the variable pitch propeller used on the Clement Bayard dirigible, the variable pitch propeller used on Italian dirigibles, and the Levasseur variable pitch propeller.

Resume of the Theory of Naval and Aerial Propulsive Propellers and of Airplanes in the Rectilinear Flight

Description: Though dissimilar, these two subjects have been united because they have some points in common. The computation of the movement of an airplane can only be correctly established if we are in a position to know exactly the thrust and resisting torque of the propeller for the various values of slip, which may vary greatly according to circumstance. The first part of the work concerns propellers and introduces as a fundamental variable, the true slip (delta) with respect to the effective pitch, whi… more

Observations on the Method of Determining the Velocity of Airships

Description: To obtain the absolute velocity of an airship by knowing the speed at which two routes are covered, we have only to determine the geographical direction of the routes which we locate from a map, and the angles of routes as given by the compass, after correcting for the variation (the algebraical sum of the local magnetic declination and the deviation).

The Dynamometer Hub and the Flywheel of the Engine

Description: Report presenting a description of the interaction between the dynamometer hub and the flywheel of the engine in aircraft. The negative rotary moments in propellers generally allow for the cessation of one cylinder without any lifting on the part of the propeller, and without depriving the engine of its flywheel.
