Abstract: It is very difficult to estimate adjusting discipline of areoengine starting fuel supply in plateau area.A new method is presented to resolve it in the paper.This method applyies TRAINBR training arithmetic of artificial neural net to estimation for adjusting discipline of areoengine starting fuel supply in plateau area,based on adjusting discipline of starting fuel supply obtained by testing in ground test bed.Through further research,matching and practical adjusting methods for fuel supplement valve adjusting screw,starting automat adjusting screw and airbleed orifice are suggested.As the experiments have showed,the benefit acquired by this adjusting method is prominent.It makes certain that areoengine can be not only started safely and reliably but also adjusted rapidly in plateau area.
