The article describes the on-board control-measurement system (BCMS) designed to record the main flight parameters of a VTOL-type unmanned micro aerial vehicle and the element base that makes up the system. Temperature, current consumption and number of revolutions of each engine, as well as the angle change and acceleration of the glider along the three coordinate axes have been measured and recorded by means of the on-board control-measuring system in the test flights performed in VTOL mode at different times and meteorological conditions. The time graphs of the recorded parameters have been made and based on them, the take-off, landing and hovering modes of the aerial vehicle have been researched. Automated recording of the measured parameters of the power elements in the pre-flight, take-off and landing modes of the VTOL micro UAV have been carried out and analyses have been performed based on the created graphs. Element base of the recording device includes. The element base of BCMS consists of a controller, TTGO display module, micro SD card module, inertial measurement unit (IMU), voltage converter, battery and temperature, current and number of revolutions sensors, as well as a ground control panel. The main element base of the BCMS includes a controller, a display module, a card module, 5 sets of sensor groups and IMU. A set of sensors consists of three types of sensors as temperature, current and number of revolutions. Purpose of work - to detect problems in the power elements of the VTOL-type micro UAV in advance and to prevent possible accidents by analyzing the flight-technical parameters recorded in the real flight by using the BCMS designed by us. Practical significance. The analysis of the parameters recorded by the BCMS aims to assess the condition of the power circuit, particularly the engines, and the serviceability of the micro UAV for the flight. It also serves to prevent potential flight incidents in advance or in real-time. #CSOC1120.
