The emphasis of this study is laid on designing a reheat-starting transient control subsystem of an aeroengine

after the main fuel control system of the engine has been designed.That is to say

the study pursued to the reheat-starting transient control method

which can coordinate the changes of the reheat fuel supply and the nozzle area

so the reheat-starting transient process does not affect the regimes of the core engine as possible

so that the engine can work safely and steadily.The optimal control method is employed with success.
