Development of Urban Air Mobility (UAM) concepts has been primarily focused on electric vertical takeoff and landing aircraft (eVTOLs), small aircraft which can land and takeoff vertically, and which are powered by rechargeable (typically lithium-ion

The electrical characteristics of two active spring thunderstorms are reported. Simultaneous surface measurements of the sign and magnitude of the free charge on individual raindrops, the electric field and precipitation rate have been made. More tha

A theoretical discussion is presented on the fundamental processes by which pulsating gas bubbles in liquids dissipate their energy. The survey is limited to the case where the amplitude of the volume pulsations are assumed to be sufficiently small t

1. A method for determining the sound generated by a submarine propeller byesting a model submarine in a wind tunnel comprising the steps of: placing said model submarine containing a propeller in an air stream; rotating the propeller of said submari

The power‐spectral densities of the pressure fluctuations in a turbulent air flow have been measured on a rigid pipe wall by a small pressure transducer. The turbulence was fully developed throughout the cross section of the pipe. Measurements were

The natural frequency of volume pulsations of an air bubble at the center of a short open‐ended rigid tube should be lower than that of a bubble of equal size in a free field. Air bubbles were generated at nozzles submerged in water in a o free fie
