Abstract

Based on a double bypass variable cycle engines

a bypass transition process was given.Using multi-components control method

the performance of variable cycle engine mode transition was numerical simulated by a steady state model.Compared with general turbofan engine

the variable cycle engines could change obviously the bypass ratio

and the SFC(specific fuel consumption) is depressed on subsonic cruise condition.
