Start-Up of a Gas Tubine Engine Using Compressed Air Tangentially Fed onto the Blades of the Basic Turbine

摘要

The use of compressed air was suggested to increase the reliability and motor lifetime of a gas turbine engine. Experiments were carried out and the results are shown in the form of the variation in circumferential force as a function of the entry angle of the working jet onto the turbine blade. The described start-up method is recommended for use with massive rotors.
