MODELING AND CALCULATION OF A GEAR CONNECTION FOR A UNIVERSAL DEVICE FOR MEASURING THE THRUST OF AN UNMANNED AERIAL VEHICLE PROPELLER

Abstract

Background. The rapid development and widespread use of various unmanned aerial vehicles requires the introduction of their typification and certification. The paper considers one of the possibilities for the development of a mechanical transmission unit for a device for measuring the thrust of a propeller-engine pair for further use for metrological purposes in the design of new aircraft. Materials and methods. The computer simulation method is based on the use of the Autodesk Inventor software package for calculating loads and selecting material for the future unit assembly. Results. In the course of the study, it was found that the computer simulation method for calculating the maximum allowable contact stresses of gear wheels for a given material satisfies the results of a classical mathematical model, with some errors. Conclusions. With the same results of mathematical calculations and calculations in Autodesk Inventor, the program greatly simplifies the work by automating the calculation process, especially when it is necessary to replace the original data.
