Designing of the Aero Video Intelligence on the STM32H Microcontrollers Basis

Abstract

The practical possibility of using the flying wing as an aero video intelligence is being considered. In this regard, an experimental sample was built with a wingspan of 1000 mm and a flight weight of up to 500 g, on that the SPRacingF3 Acro flight controller was installed on the basis of the STM32F303 microcontroller with a GPS receiver and a course video camera for FTP flights. Based on the INAV firmware, the main attention was paid to setting the flight modes NAV RTH, NAV FAILSAFE to ensure the guaranteed return of the wing to its launch zone in case of the radio communication loss with the video camera or control panel. The microOSD board has been configured for the possibility of the overlaying telemetry data on the images, that received on the monitor from the course camera. The setup and testing of the semi-automatic launch of the NAV LAUNCH flying wing was carried out, that greatly facilitated the start of the wing in windy weather and from the small areas. It has been practically shown that the flight time was about 40 minutes at an average speed of 40-45km/h with the 5x3 inch three-blade propeller on the three Sony / Murata US18650VTC5 rechargeable batteries with the capacity of 2600 mah.
