Abstract
Objective: To determine the possibility and directions for increasing the efficiency of gas turbine traction based on the experience of using gas turbine engines as power plants in railway transport. Methods: The practice of operating gas engine locomotives in trial runs and normal operation with trains of 9 thousand tons is used. Records of onboard systems for fixing the parameters of locomo-tive equipment operation are taken into account. Results: Comparison of the application experi-ence of gas turbine engines in various branches of the national economy are carried out. The fea-tures of using gas turbine engines in unstable loading modes are analyzed. Their effectiveness is characte¬rized and directions for its further increase are established. The values of the maintenance labor intensity of gas turbine locomotives and diesel locomotives are revealed. The actual load of gas turbine locomotive equipment at all traction modes has been determined. Practical im-portance: Significant differences in maintenance of power units of gas turbine locomotives and die-sel locomotives have been determined. The performed analysis of the operation results allowed to determine and prove in practice the advantages and disadvantages of convertible aircraft gas tur-bine engines, to establish requirements for them in order to increase the efficiency of using gas turbine locomotives and to develop a draft of technical requirements for a power unit for the main gas turbine locomotive GT1h.
