Abstract:

Guided by the compatibility assessment for the next-generation advanced stealth aircraft’s intake/engine, this paper reviews the research progress and development directions of aeroengine swirl/total pressure combined distortion testing and evaluation techniques. Focusing on distorted flow field testing, the principles and technical challenges of typical steady/dynamic probe measurements in flow fields with airflow deviation angles are introduced. The difficulties in applying conventional measurement point distributions to complex swirl/total pressure combined distortion pattern testing are analyzed. Regarding the design of distortion generators, the structural composition and principles of commonly used total pressure and swirl distortion generators are summarized, and the design approaches and challenges of typical combined swirl/total pressure distortion generators are outlined. In terms of distortion index definition, various methods for defining total pressure and swirl distortion indices, along with their correlation to engine stability, are listed. Two approaches for correlating combined swirl/total pressure distortion intensity with engine stability are presented, and the necessity of developing a combined swirl/total pressure distortion index is discussed. Based on the current state of technology domestically and internationally, key technical directions for future research are explored, including accurate steady/dynamic flow field testing under large airflow deflection angles, design of measurement point distributions for complex combined distortion patterns, efficient design and continuous adjustability of combined distortion generators, and the definition of combined distortion indices that reflect changes in engine stability.

Key words: inlet duct of stealth aircraft, aeroengine, combined distortion of swirl/total pressure, distortion measurement, distortion generator, distortion descriptor
