Performance of Airships,gineers, so that it is not surprising that scientific literature regarding the aerodynamic performance characteristics of airships is scanty and mostly scattered through disconnected monographs, cumbersome to collect and not readily available to the student. It was therefore felt that the General Ed

Hydrodynamics of Boats and Floats, performance of these craft involves two distinct phases, on the surface of the water and in the air, the one merging into the other at the moment of take-off from the water, or of returning to the same. When flying, the basic problems of marine aircraft are similar to those of land craft except as

Aerodynamics of Cooling,e experimental aspects of this subject have been sufficiently developed to permit a logical presentation starting from a few basic assumptions and progressing to the mathematical solution of simple illustrative problems. Instead, it is found necessary to review the progress made along several indepe

In addition there is a considerable body of theoretical knowledge not yet expressed in precise mathematical form, relating principally to the factors controlling the transition from laminar to eddying flow, which is of sufficient importance to record.
