Abstract
The design of an electromagnetic balance using superconducting coils is reported. Both dc and ac coils are used to support aerodynamic models in a supersonic (Mach 3) wind tunnel and to simultaneously measure the forces acting on them along 3 orthogonal axes. Major design characteristics include: adoption of symmetrical coil arrangement to provide maximum space for the wind tunnel; 3 gradient‐coil pairs capable of being driven between 0 and 350 A at a frequency of 30 Hz by specially designed power supplies; a vertical wind tunnel with a 6‐in. test section located in the axial room‐temperature access of a 250‐liter liquid‐helium Dewar. Results on ac losses for prototype gradient coils wound of three different superconducting materials are reported.This publication has 4 references indexed in Scilit:
