My experience with helicopters
The author recounts his experiments with helicopters. The object of his investigations was to remain stationary in the air for five minutes and to make a closed flight at low altitude. Some of the topics discussed include stabilization, horizontal flight, and directional control. digital.library.unt.edu/ark:/67531/metadc57286/
The New Interpretation of the Laws of Air Resistance
A closer examination of Newton's formula for air resistance shows that it is well to consider the air as an ordinary fluid, and, indeed for most of the velocities considered, as a non-compressible fluid, so long as the dimensions of the moving body are large in comparison with the mean free path of the particles of air. digital.library.unt.edu/ark:/67531/metadc57134/
Wind-driven propellers (or "windmills")
Wind-driven propellers are much used as sources of power for equipment such as radios. This report establishes the principles involved and acquaints the reader with rules for design of such windmills. digital.library.unt.edu/ark:/67531/metadc57288/
