Abstract

The paper presents methods for estimating the inaccuracy of determining the angular position of the pilot’s helmet dedicated to the NSC-1 Orion helmet-mounted cueing system with a magnetic method, intended for the W-3PL Głuszec multi-purpose helicopter with integrated avionics system ZSA. A flat coil with two separated rings, which generates a magnetic field with a curved profile from the axis of symmetry, developed in the Polish Air Force Institute of Technology (AFIT), was presented. The magnetic field curvature causing errors of determining the angular position of the pilot’s helmet in relation to the aircraft cabin reference frame was described with the use of relationships formulated for the flat coil with two separated rings (inner and outer). The inaccuracies determined on the basis of computer simulations of the developed mathematical relationships were compared with experimental data obtained from the magnetic field measurements using the integrated ADIS 16405 triaxial sensor (with a measurement resolution of 0.5 mgauss/LSB). In order to improve the accuracy of determining the angular position, an original algorithm for specifying linear deviations of the pilot’s helmet from its neutral position, determined during the adjustment process of the helmet (located on the axis of symmetry of the flat coil) was used. It allowed to determine the current curvature of the generated magnetic field and to make corrections.
