The application belongs to the technical field of aero-engine state detection, and in particular relates to a method for determining the law of total afterburner fuel flow control. The method includes calculating the performance of the full afterburner state, obtaining different engine inlet total temperature deviations and afterburner oil-gas ratios under different engine inlet total temperatures; obtaining the aircraft altitude and calculating the corresponding ambient temperature under standard atmospheric conditions; obtaining Calculate the Mach number of the aircraft and calculate the corresponding total temperature of the inlet inlet; determine the total temperature deviation of the engine inlet; interpolate and calculate the fuel-air ratio of the afterburner, so as to obtain the total fuel flow control law of the afterburner. This application considers the non-standard weather conditions The afterburner total fuel flow control law can effectively solve the problem of poor applicability in non-standard weather conditions existing in the existing rules, and can effectively improve the performance and work safety of the engine in non-standard days.
Description
technical field [0001] The application belongs to the technical field of aero-engine fuel control, and in particular relates to a method for determining the law of total afterburner fuel flow control. Background technique [0002] Afterburner total fuel flow control law generally refers to, according to the engine inlet total temperature T t2 , formulate the corresponding oil-gas ratio W fab / P t3 . [0003] With the development of aviation science and technology, military aircraft are required to have the ability to fly at a sudden increase in flight speed when taking off, climbing or performing interception tasks, and gas turbine engines with afterburners have emerged as the times require. Fuel is supplied to the afterburner by the afterburner fuel control system, and the fuel is mixed with the oxygen contained in the turbine and the outlet airflow of the outer culvert again to achieve the purpose of further increasing the engine thrust. At present, the general design ...
