Abstract: Modern commercial aircraft are often powered by ultra-high bypass ratio (UHBR) engines, which leads to an increasingly short distance between the engine and the aircraft wing. The close integration between the UHBR aeroengine and the aircraft wing results in pronounced installation effects on jet noise. The mechanism, prediction and control of these installation effects play a key role in the low-noise design of modern aircraft. This paper reviews the recent advances in the study of subsonic jet noise installation effects from three perspectives: physical mechanisms, prediction models, and noise control techniques. Regarding the physical mechanism, this review highlights that the strong noise amplification at low frequencies occurs due to the scattering of near-field evanescent pressure fluctuations by the wing’s trailing edge. This scattering mechanism accounts for the observed dipole-like radiation characteristics and the exponential dependence of noise intensity on the radial installation distance. In addition, the generation mechanisms for both mid-to-high frequency noise and discrete tones are also discussed. Regarding the prediction models, progress based on high-fidelity numerical simulations is summarized, along with the development of physics-informed reduced-order models based on scattering theories. Recent advances in data-driven models for rapid noise prediction are also discussed. Regarding the noise control, both passive control strategies, such as nozzle, wing/flap geometric optimization and surface treatments, and active control methods using plasma actuators and piezoelectric devices are reviewed. By systematically summarizing current research progress, this paper aims to provide a reference and insights for optimizing engine–airframe integration, improving airframe design, and developing advanced noise-reduction technologies.
