Background. The need to obtain information on the physical processes, technical characteristics of systems and assemblies of aircraft engines, information on the functioning and interaction of component systems, ensuring the optimal operation of the engine requires the creation of special sensors for aircraft products. The role of sensors is decisive in any measuring system. The reliability and efficiency of various types of aviation technology increasingly depend on their characteristics. The technical characteristics of the sensors greatly affect the technical level of the control and diagnostic tools themselves. In particular, the creation of sensors for measuring angular displacements capable of  roviding an optimal operating mode of an aircraft engine. Therefore, the development and improvement of the fleet of modern sensors can be singled out as one of the most important areas of increasing the efficiency of aircraft products.
Materials and methods. The methods of integral and differential calculus, analytical geometry, the theory of electrical circuits and the electromagnetic field were used for solving the set tasks. KOMPAS and AutoCAD computer-aided design systems were used for designing the sensor structures.
Results. As a result of the work carried out, an angular displacement sensor with a built-in electronic transducer on the basis of an Analog Device microcircuit, designed to work with differential transformer displacement sensors, was developed. The sensor meets the requirements for accuracy, reliability and resistance to external influences and can be used to measure the angular displacements of the guide vanes of an aircraft gas turbine engine compressor.
