Comparative characteristics of diesel engines and gas turbine power plants for mobile vehicles

The paper considers the use of diesel-electric power plants on mobile vehicles, analyzes their use and application. Comparative power and mass characteristics of diesel and gas turbine power units are given; the positive and negative aspects of their use are shown. The efficiency of the introduction of gas turbine engines on tractors of various traction classes for agricultural purposes has been determined and a new kinematic diagram of the power plant of a mobile vehicle has been developed. An analysis was carried out and it was established that gas turbine agricultural equipment was never produced in Russia. There were carried out the individual experimental studies of not of a systemic nature, which were terminated for reasons independent of the result. The aim of the work is to develop an innovative kinematic diagram with an electric drive and a power unit based on a gas turbine engine for a mobile agricultural vehicle, using the latest advances in science and technology in terms of the development of gas turbine technologies. It has been established that the mass-energy characteristics of gas turbine plants are much better than diesel ones: the level of vibration is significantly lower, the torque of the power plant at low speeds is higher, the operation of the tractor is simpler. All these open up wide prospects for their use on mobile agricultural vehicles. Experimental studies on the processing of 1 hectare of area in terms of economic efficiency have shown the indisputable advantage of an almost laboratory model of a tractor with a gas turbine engine, relative to the same tractor with a diesel engine, which has been produced for many years, expressed, despite a slightly higher fuel consumption, in the use of cheaper kerosene.
