摘要:
A method of operating an electrical power generation system (100) on an aircraft (900). The method comprises assessing a required electrical power of the aircraft (900), assessing whether a first (102) and a second (53) electrical power source are able to provide the required electrical power in combination, assessing a predetermined condition, determining an operating mode of the first and second electrical power sources (102, 53) to match the predetermined condition, and operating the first and second electrical power sources (102, 53) according to the determined operating mode.

摘要:
A method of controlling a gas turbine engine (10) which has a booster compressor (13), a core compressor, combustion equipment, a core turbine, and a low-pressure turbine (18). The low-pressure turbine also drives an external load having a defined speed characteristic. The booster compressor (13) has one or more rows of variable stator vanes. The method includes: scheduling variation in the angle of the variable stator vanes as a function of the speed of the booster compressor such that the vanes open as the booster compressor speed increases; measuring or setting one or more operational parameters which are determinative of the temperature at entry to the core turbine; and biasing the scheduling of the angle variation of the variable stator vanes as a function of the operational parameter(s) to reduce variation in temperature at entry to the core turbine
