| description | The authors of this article propose a research technique of unmanned aerial vehicle (UAV) dynamic behavior in ground conditions with account of flight experiment data. Dynamic researches of UAV and separate components of its onboard equipment are one of the most important tasks of the ground testing stage of UAV. The flight experiment gives the most reliable information about the vibration condition of the UAV and its onboard equipment. However to identify the real vibration condition of the UAV requires the installation of a sufficiently large number of accelerometers, which technically can be unrealizable during flight studies. It is proposed to solve this problem by conducting ground dynamic tests. Having determined the nature and level of vibration during the full-scale (flight) experiment in the "reference" places, it is possible further in the laboratory with a high degree of reliability to obtain vibrations (amplitude and phase frequency characteristics, spectrum, etc.) in other places of the UAV construction. To do this, it is necessary to install accelerometers throughout the UAV airframe, including the "reference" places that were used in the flight experiment. By exciting the UAV alternately along the longitudinal and lateral axes with the vibration spectrum obtained in the full-scale experiment, the vibration spectrum is reproduced in those places where accelerometers are installed in the laboratory experiment. In this case, the vibration task is carried out by "reference" accelerometers, as in the full-scale experiment. In the future, the resulting vibration process can be transferred to autonomous studies of the automatic control system and its individual units, actuator, rudder – drive system, etc. to assess their functioning in these vibration conditions. In addition to the main provisions of the technique, the article presents a schematic diagram and an example of the dynamic behavior research of UAV in ground conditions with account of flight experiment data. |
