Telemetrie- und Steuerungsmodul für Viertaktmotoren im Flugmodellbau

Abstract

This thesis deals with the feasibility analysis and development of a telemetry and control module for large four-stroke model engines. These high-quality engines, ranging in size from 50 to 360 cm3 , are mainly used in scale models due to their authentic sound. These models, which are closely based on real-life counterparts, are characterised by a high degree of technical detail. As a result, modern control systems are essential for operational safety in order to ensure reliable and safe flight operations. The aim of this thesis is to develop a prototype that measures data from the engine and transmits it to the receiver via common protocols used by receivers. Particular important is to the galvanic isolation between the control and ignition sides in order to prevent interference with the receiver due to high-frequency interference from the ignition. Furthermore, the ignition, throttle position and starter motor are controlled via the module. One focus of this work is on the design and implementation of the hardware and software architecture that serves as the basis for the module’s functionality. The hardware includes the use of microcontrollers, voltage regulators for the various supply voltages required, and various sensors, supplemented by protective circuits for inputs and outputs. In the course of this work, different architectural concepts are discussed and a prototype was developed that combines all previously defined functions in an integrated system. The software is modular in design to enable flexible adaptation and expansion, such as speed control. Configuration via PC allows for easy operation. The result of this work demonstrates the feasibility of a comprehensive solution for telemetry and control of motors in model making. The developed prototype forms the basis for further research and industrial applications.
