History and Development of Gas Turbine Locomotive Power
The concept of using gas turbines for locomotive power dates back to the 1940s, when the first prototype of a gas turbine-electric locomotive was developed by General Electric (GE). The GE turbine-electric locomotive, also known as the “Turbine-Electric Locomotive,” was a significant innovation in the field of transportation, offering a more efficient and powerful alternative to traditional steam and diesel-electric locomotives. Over the years, gas turbine locomotive technology has continued to evolve, with various manufacturers and research institutions contributing to its development.
Principles of Gas Turbine Locomotive Power
A gas turbine locomotive works on the principle of using a gas turbine engine to generate electricity, which is then used to power electric traction motors. The main components of a gas turbine locomotive include the gas turbine engine, generator, and electric traction motors. The gas turbine engine uses a combination of air and fuel to produce a high-temperature and high-pressure gas, which is then expanded through a turbine to generate mechanical energy. This mechanical energy is converted into electrical energy by the generator, which is then used to power the electric traction motors. The electric traction motors, in turn, propel the locomotive forward, providing the necessary traction and braking forces.
