Opis:: The article presents the selected methods of identifying static and dynamic properties of the measuring paths to the extent necessary for the proper integration of on-board systems with the helmet-mounted flight parameter display system. It presents the methods of identifying static and dynamic properties of the WR-10MK on board variometer as one of more difficult identification elements. Its identification was carried out on the basis of the basic dependencies of the International Standard Atmosphere and the instruments construction’s parameters. It built a mathematical model describing the physical phenomena associated with vertical speed measurement. This model differs from the models found in the literature in terms of detail and description accuracy. On this basis, in the Simulink environment, it built a simulation model corresponding to its mathematical model. The non-linear model was the starting point for the construction of the linearized model based on the operator transmittance. The developed models were evaluated for errors of vertical speed’s dynamic indications. This allowed assessing the usefulness of the individual models for further works on ensuring the correlation of indications of the on-board variometer and the SWPL-1 helmet-mounted flight parameter display system. The presented simulation models include design details, as well as the characteristics of technological errors and disturbances of a stochastic nature. Another approach to the issue of identification is to use the characteristics provided by the manufacturer in the form of approximate characteristics of a module.

Opis:: The paper presents the structure and basic properties of the SWPL-1 helmet-mounted flight parameter display system, constructed for the Mi-17 helicopter with analogue systems and on-board instruments. It describes the basic components of the SWPL-1 system and on board components cooperating with the SWPL-1 system necessary to ensure the imaging system’s operation (including the ADU-3200 central unit for aerodynamic data and the GPS-155XL satellite signals receiver). It presents the architecture, the principle of operation, and the main constituents of the SWPL-1 helmet-mounted flight parameter system, as well as the standards of data transmission used in digital communication between the SWPL-1 system and on-board systems (installed on the Mi-17 helicopter). It describes the scope and manner of pilot and navigation data presentation as well as control of drive unit operation parameters in detail. It presents selected optimization methods for tasks executed in the helmet mounted system’s life cycle. The particular stages of the life cycle were described in detail, from the earliest stages of needs identification, through the analytic and conceptual phase, then the implementation stage, and ending with the operation stage. It introduces tasks for optimization and related methods into the process of creating the new system at every stage of its implementation. It presents one of the methods of multi-criteria optimization based on the experts’ assessment of choice of a variant of the helmet-mounted flight parameter display system’s hardware architecture in detail.

Tytuł:: The magnetic field curvature correction algorithm dedicated for helmet mounted cueing systems

Tematy:: transport

flat coil profile modelling
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.
