Formulation of the problem. The reliability of the wireless monitoring system of a gas turbine engine, which consists of small-size sensors with minimal power consumption of radio transmitters and a radio receiver, depends on the configuration of their location and the intensity of the interference of signals reflected from the metal parts of the engine.

Purpose of the article. Determine the installation locations of a radio receiver to provide time separation of ultra-wideband (UWB) signals from each sensor by using the method of three-dimensional modeling, taking into account the multipath propagation of signals between the nodes of a gas turbine engine and a metal engine nacelle of various configurations.

Results. It has been established that the level of interference between signals at the receiver input depends significantly on the shape of the engine nacelle. An assessment of the permissible inaccuracy of mounting the receiver with an antenna has been carried out. By means of simulation modeling, a comparison of various types of radio transmitter antennas was carried out. The best location of the receiver on the body of the engine nacelle has been found.

Practical significance. The results obtained can be used in the design of a wireless monitoring system for gas turbine engines.
