Starting and controlling speed of a two spool gas turbine engine

摘要: Two spool gas turbine engines are often used to drive variable speed loads, such as an electric generator, or the fan/propeller of aircraft engines. The engine must be designed withstand transient and temperature conditions which encountered when sudden changes load on fan, propeller occur. By adding a relatively small motor/generator generator engine, compressor airflow can quickly adjusted compensate for external changes. This reduces severity duration conditions, resulting in decreased operation reliability problems overspeed, surge, high temperature. may also starting device.
