Opis:
The following paper presents a method of determining the angular position of the pilot’s helmet based on the measurement of magnetic field components, artificially generated on board the aircraft (similarly to the helmet-mounted cueing systems of the F-16 aircraft). We presented a mathematical model, which describes determining of the angular position of the pilot's helmet, based on the measurement of the magnetic field components in various moments of powering orthogonally fixed magnetic coils. We also defined modelling capabilities of the helmet-mounted cueing system, which uses the magnetic method to determine the angular position of the pilot's helmet. It has been shown that the direction cosine matrix can be used for determining the angular position of the pilot's helmet, specified based on the matrix formed from the magnetic field components in various moments of powering orthogonal magnetic coils. The paper ends with an outline of simulation tests, which enable to identify the errors of the system, using such a method.

Opis:
The article presents selected results of the analytical work carried out in the Air Force Institute of Technology regarding the possibility of computer matching systems, digital display and analogue devices, both in the static states and in dynamic states while manoeuvring the aircraft. On the example of parameter of vertical speeds provided a method of matching the indications for the helicopter Mi-17-1V with built helmet-mounted display system of flight data SWPL-1 Cyclops (developed by the Air Force Institute of Technology and cooperating with analogue avionics). Adjusting the display of vertical speed achieved by an inertial element of first row, implemented programmatically in the computer graphics KG-1. On the other hand, method of adjusting of indications on the information presented in the helmet-mounted cueing system NSC-1 Orion (built in the Air Force Institute of Technology for helicopter W-3PL Capercaillie) and obtained from the integrated avionics system (with digital avionics), exemplified by magnetic heading (obtained from heading layout KCS-305) and geographic heading (obtained from inertial navigation system EGI-3000). Adjusting of indications realized by introducing amendments to the indications of the multifunctional monitor MW-1, translucent display HUD and helmet-mounted display WDN-1 (in the form of elected declination, implemented programmatically on the computer mission KM-1) and the amendments to the magnetic deviation (introduced periodically to heading compensator layout KCS-305).

Opis:
The article presents the new built in Poland helmet mounted cueing system NSC-1 Orion with a magnetic method, dedicated to the multi-purpose helicopters W-3PL Gluszec. This system uses the magnetic field generated by the system of three mutually orthogonal electric coils. The principle of operation of this system is described and the method of determining the angular position of the pilot's helmet relative to the helicopter's cabin using the reference magnetic field and the directional cosines matrix are discussed. Electrical flat coils, constructed in the Polish Air Force Institute of Technology (AFIT), generating a magnetic field with curved symmetry axis characteristics, causing errors in determining the angular position of the pilot's helmet are shown. As a way to minimize these errors, an original proprietary algorithm for correcting the negative impact of the magnetic field curvature generated by the on-board system has been presented. Mathematical relations describing the presented correction process as well as selected results of simulation and experimental investigations in the area of inaccuracy of the "before" and "after" systems of applying the developed algorithm were given. Inaccuracies determined from computer simulations of the developed mathematical relations were compared with experimental data from magnetic field measurements using the integrated three-axis sensor ADIS-16405, used in the laboratory of the AFIT Avionics Division for helmet control of the angular position of the moving observation and sighting head and reflector-search light.
