CONTRIBUTION TO THE KNOWLEDGE OF MAGNETIC BALANCE AND SUSPENSION SYSTEMS.
Abstract
The report separates, for the purpose of discussion, into three distinct parts: comments on design studies for a large scale balance system; experimental studies of problems relating to the multiple use of an advanced configuration of coils for roll, pitch and yaw; and studies of a calibration system capable of automatic operation. The first part is a brief discussion of the philosophy behind the design. The nature of the compromises is included as well as a discussion of the performance goals for the design. The second part describes studies conducted to determine whether or not the pitching and yawing moment coil can also be used to generate rolling moments. In particular the problem of isolating the roll power supplies from the pitch and yaw power supplies, while loading the coils simultaneously, was studied in detail. It was found that this problem can be solved simply and that primary problems associated with multiple use of the coils include selection of the conductor, maximum potential and cooling. The third part contains a description of a multiple purpose calibration system. This system can either be used in the classical sense of applying the several loads and measuring the output from the data readout, or in the inverse sense that entails fixing currents in the magnetic balance and, by using the calibration system as a mechanical balance, determine the forces and moments on the model. While the latter use is unconventional it offers the promise of a fully automatic procedure. (Author)
