Preliminary calculation of cylinder dimensions for aircraft engines

Preliminary calculation of cylinder dimensions for aircraft engines

Date: September 1, 1921
Creator: Schwager, Otto
Description: It is extremely important in building aircraft engines to determine the requisite cylinder dimensions as accurately as possible, in order that the weight required for a given power shall not be excessive. This report presents a calculation method that depends on the air requirement of the fuel.

Abacus giving the variation of the mean pressure of an aviation engine as a function of its speed of rotation

Abacus giving the variation of the mean pressure of an aviation engine as a function of its speed of rotation

Date: March 1, 1921
Creator: Margoulis, W
Description: Comparing the results of the calculations for computing the mean pressure of an aviation engine for any number of revolutions, with those of experiment, the writer, by numerous examples, shows the perfect agreement between them. This report will show that, by means of a special abacus, an engineer can instantly plot the characteristics of an engine.
