The Calculation of Downwash Behind Supersonic Wings with an Application to Triangular Plan Forms


Book Description

A method is developed, consistent with the assumptions of small perturbation theory, which provides a means of determining for a known load distribution, the downwash behind a wing in supersonic flow. THe analysis is based upon the use of supersonic doublets which are distributed over the plan form and wake of the wing in a manner determined from the wing loading.

Investigation of Fretting Corrosion by Microscopic Observation


Book Description

Fretting corrosion was concluded to be caused by the removal of finely divided and apparently virgin material due to inherent forces and that its primary reaction is independent of of vibratory motion or high sliding speeds. Fretting corrosion occurred to clean nonmetals and metals readily and glass microscope slides and steel balls provided an excellent method for visual studies.

Method of Calculating the Lateral Motions of Aircraft Based on the Laplace Transform


Book Description

The lateral motions of aircraft are obtained by means of the Laplace transform which gives solutions in terms of elementary functions for the free motions and the motions due to forcing step functions. The lateral stability of a specific airplane and certain of its free and forced motions are calculated.
