Design of S-Shaped Submerged Inlet
Advanced Materials Research, 2011 The influence of centerline and the cross-section variation to aerodynamic performance of the inlet was researched in a wider range. A new method of measuring the total pressure recovery coefficient and total pressure distortion coefficient of the inlet was proposed.

Adjoint-Based Design Optimization of Vortex Generator in an S-Shaped Subsonic Inlet
AIAA Journal, 2012 This paper deals with an adjoint-based design optimization of vortex generators for the performance improvement of an S-shaped subsonic inlet, the Royal Aircraft Establishment intake model 2129. To enhance the flow quality entering the engine face maximally, the vortex generators are independently optimized with five design parameters per each vortex ...

Abstract The S-shaped inlet of the modern military aircraft propulsion system suffers from severe inlet distortion during flight maneuvering. The complex distorted flow field is generally decomposed into total pressure and swirl distortion, both of which could substantially degrade the performance and stability of an aero-engine.

Investigation of two-phase flow characteristics of an S-shaped inlet in rain
Physics of FluidsRain, a common weather hazard for aircraft, is one of the major causes of several catastrophic flight accidents. Stealth aircraft commonly employ S-shaped inlets, which are frequently subjected to extreme external environmental effects like rain during mission execution.

Research on electromagnetic scattering and plasma stealth design of S-shaped inlet
2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017Inlet duct is a strong scattering source of radar waves due to its cavity structure which can make multiple reflections of electromagnetic wave through the cavity walls. Moreover, the complicated cavity structure always makes it difficult to obtain its scattering characteristic.

A computational analysis tool was used to characterize the flow structure in an S-shaped intake to determine the relationship between inlet shape and angle of incidence and to study the reduction of flow distortion on the engine face. A Royal Aircraft Establishment M 2129 S-shaped intake was used to establish the reliability of the proposed ...

Design and analysis of the mandrel structure for a composite S-shaped inlet
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021Automated fiber placement (AFP) combining with the autoclave curing process is the main manufacturing method for large-scale rotary composite parts. During the forming process, the mandrel plays an important role that affects the forming quality of the part directly.

Quantification of Swirl Distortions Caused by S-shape Inlet Ducts
Proceedings of Global Power & Propulsion Society, 2022The S-shape inlet is generally the main reason for the occurrence of swirl inlet distortion that is seriously concerned by the manufactures of fighters. The non-uniform inlet combined with large-scale bulk swirl, small-scale tight-wound swirl, or both of them may greatly impact the performance of aero-engines.
