Design of Flywheels for Motor-Driven Impulse Wheels

The author investigates the problem of the design of flywheels for motor-driven impulse machines. He analyzes the characteristics of torque and speed curves of such machines and derives expressions by which the characteristics of these curves may be determined. A method of drawing such curves by means of a transmission dynamometer and steam-engine indicator is described. In appendices the author gives the derivation of the fundamental equations involved and of the working formulas which he presents, and makes calculations for an actual case. He also makes use of the Fourier development of the torque-time diagram as one method of solution.
