文摘

The effect of combined use of variable guide vanes and bleed air is evaluated. The genetic algorithm is employed to find the optimum setting angle and bleed air. A low bypass ratio mixed turbofan engine is analyzed for optimization. Additional use of the bleed air shows improved overall performance of the engine.
