Some Control and Accessory Considerations for Gas Turbines — An Engine Manufacturer's Viewpoint

The ever-increasing turbine engine complexity dictates an increase in control and accessory complexity. Additional engine parameters must be monitored and controlled to assure proper engine operation. The guarantee of extended life and reduced maintenance requirements coupled with the increased complexity require an almost perfect reliability in each subcomponent and in each component. Reduced maintenance will be obtained through condition monitoring. Integration of the engine-airframe control and the condition monitoring systems is mandatory if certain goals are to be attained. Some future control and accessory considerations, such as improved utilization of existing components are briefly discussed. A prime area of concern and one requiring much work is in data conditioning. It is concluded that standardization and a tightly controlled sensor transducer program will aid in achieving a totally integrated system.
