| Summary: | Background. The relevance of the use of unmanned aerial vehicles for solving problems in various branches of technology is considered. The features of constructing altimeters of various types are analyzed. The aim of the work is to improve the characteristics of barometric altimeters based on pressure sensors used in control systems of unmannedvehicles used in UAVs. Materials and methods. The study is carried out by the method of simulation of sensitive elements in the COMSOL Multiphysics software package and determination of the sensitivity of the transformation and the linearity error of each of them. Results. The geometric parameters of the sensing element are determined, the sensitivity of the conversion and the linearity error of the output signal are calculated. Conclusions. A profiled membrane with certain geometric parameters allows you to achieve the best technical characteristics in comparison with flat membranes in terms of conversion sensitivity and linearity error of the output signal. |
