Static stability of seaplane floats and hulls

Description: Values of lateral and longitudinal metacentric heights for various seaplanes were calculated by means of approximate formulae derived here. The data are given in tabular form. Upon plotting these metacentric heights against the corresponding gross weights, it appears that the metacentric height is approximately a straight line function of the gross weight.

Note on Vortices on Their Relation to the Lift of Airfoils

Description: "This note, prepared for the NACA, contains a discussion of the meaning of vortices, so often mentioned in connection with the creation of lift by wings. The action of wings can be more easily understood without the use of vortices" (p. 1).

The influence of inlet air temperature and jacket water temperature on initiating combustion in a high speed compression ignition engine

Description: Report presenting some tests to determine the influence on initiating combustion in a one-cylinder compression ignition engine of inlet air temperature and jacket water temperature. The results show that the engine is very sensitive to changes in final compression pressure, induced by a change in the initial compression pressure, and that some way of providing compensating means for conditions that tend to lower section pressure is necessary.
