Hydrodynamics of Boats and Floats,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 they may be modified in detail by necessary changes in form and proportion resulting in relative differences in the location of the center of gravity and in the thrust line of the propeller.hematuria 发表于 2025-3-25 16:42:17
Performance of Airships,rested in lighter-than-air craft. The present authors accepted the invitation to contribute to this work with a full realization that they can do only partial justice to the presentation of such a vast and intricate subject.天气 发表于 2025-3-25 21:18:42

Controlling mit der SAP Analytics Cloudmain of aerodynamics and since special airship aerodynamics should contain as its most notable problem the full analysis of airship drag, it seems quite possible that from airship theory may some day come forward such fundamental progress in aerodynamics as shall revolutionize our technique of air tLeaven 发表于 2025-3-26 05:22:09
