Title
Summary Report: Study Of Electrical Energy Conversion Systems For Future Aircraft
Description
Energy-conversion studies in progress in the fields of magnetohydrodynamics and electromechanics are summarized, and work completed both in these fields and in thermoelectric and electromechanical energy conversion is briefly described.

Work on magnetohydrodynamics of both liquids and gases in reported in Chapters II and III, respectively. Chapter II, Part A, deals with magnetohydrodynamic channel flow of incompressible fluids and includes a theoretical approach to turbulence, energy-conversion relations for Hartmann-type flow, and a description of an experimental investigation of velocity profiles. Chapter II, Part B, covering the work on liquid metal devices, gives further information on the development of a liquid metal d-c transformer and a mercury arc oscillator for d-c to a-c conversion, and reports progress on the testing of liquid metal brushes for a homopolar motor.

Chapter II discusses energy-conversion processes for compressible fluids in both steady and pulsed flows. The latter is illustrated by analysis of an eddy-current generator from both field and circuit viewpoints. A literature survey of work on the time-dependent MHD problem is given; and experimental investigations, using a magnetically driven shock tube and a toothed-wheel machine, are reported. Further developments of microwave diagnostic equipment for a shock tube are reported.

Chapter IV is concerned with work on frequency-power formulas and their application to electromechanical energy conversion. Four basic types of frequency-power formulas are developed using a state function approach; and their significance in system analysis is discussed both generally and with the aid of examples.
