The article is devoted to the broadband vibrodiagnostics of jet engines. The material discusses the main causes that affect the level of vibration of the engine. Using the methods for controlling vibrations in a wide frequency band, an analysis was made of the criteria that cause defects and their manifestations in a wide frequency band of vibrations. The author has studied the effect of defects in parts and assembly units on vibration levels in a wide range. Based on the data obtained, it was found that the results allow to determine the bottlenecks of the gas turbine engine with accuracy to the details of the assembly units.
