Paper Abstract

Fiber Optic Gyro (FOG) coils have traditionally been produced by cylindrical winding techniques. Regardless of the type of cylindrical wind, standard or quadrupolar, the resulting coils contain fiber crossovers that degrade performance. In 1998, the U.S. Army patented a fiber coil configuration that essentially eliminated crossovers, was thermally symmetric, and allowed the use of inexpensive single-mode (SM) fiber. The crossover-free fiber optic gyro (CFOG) necessitated a paradigm shift in coil production methodology. The CFOG coil design was analyzed in depth to determine manufacturability. Design enhancements were made to enable automated high speed fabrication, resulting in the Improved Crossover-free Fiber Optic Gyro (ICFOG). A prototype Fiber Placement Machine (FPM) was designed and constructed to produce CFOG coils. The fiber placement concept was verified by producing test articles and complete coils.
