“…With the development of distortion simulation, scholars have proposed new methods such as the delta wing method, blade method, square cylinder method, strip distortion generator, complex total pressure distortion screen, curved edge plate, and swirl chamber method (Mankbadi and Georgiadis, 2015;Yusoof and Deshpande, 2015;Sivapragasam, 2019;Cheng et al, 2020;Song et al, 2021). Wu et al (2022) used the BP ANN method to predict the dynamic distortion flow field of a crescent shaped distortion generator. Through numerous experiments, the United States has developed definition criteria and relevant industry standards for aerospace inlet distortion (SAE S-16 Committee ARP 1420, Revision B, 2002; SAE Aerospace Information Report AIR-1419AIR- , 1999.…”
