  • The mode match method has been used for the liner design and optimization of the low speed fan facility. The experimental results and the trend of the calculation results are identical with each other. 2 liners both has significant effect for the +4 order mode of 2 blade passing frequency (BPF). The first forward liner's insert loss is 30.4dB, and the backward liner's insert loss is 20.25dB; the second forward liner's insert loss is 21.85dB, and the backward liner's insert loss is 18.85dB. It's proves that, mode match method can be used in the liner design and optimization, and the experimental platform for the nacelle design was gotten. The cost of liner design for the aero engine nacelle can be reduced.
