Analysis of Current State of the Starting Device for Aircraft Gas Turbine Engines

Abstract

Current trends in the aviation industry are aimed at upgrading avionics and replacing mechanical, hydraulic and pneumatic systems in favor of electrical systems. The article contains an analytical review of the starting devices of the gas turbine engine of an aircraft. The article analyzes the starting characteristics of an aircraft gas turbine engine, as well as the requirements for the design of electric starting devices of an aircraft engine. Options for building starter-generator systems to increase the level of electrification of aircraft onboard equipment, within the framework of the concept of “more electric aircraft”, are considered. Along with increasing the level of electrification, the problem of increasing the energy efficiency of existing electrical equipment of aircraft is acute. One of the criteria for the effective use of aviation equipment is the introduction of multifunctional onboard units and units. According to this criterion it is advisable to combine the starter and generator of the auxiliary power unit in one module.
