A survey of inlet/engine distortion compatibility [PDF]
19th Joint Propulsion Conference, 1983 The history of distortion analysis is traced back to its origin in parallel compressor theory which was initially proposed in the late fifties. The development of this theory is reviewed up to its inclusion in the complex computer codes of today.

Control of Inflow Distortion in a Scarf Inlet [PDF]
8th AIAA/CEAS Aeroacoustics Conference & Exhibit, 2002 The scarf inlet has the potential to reduce aircraft inlet noise radiation to the ground by reflecting it into the space above the engine. Without forward motion of the engine, the non-symmetry of the inlet causes inflow distortion which generates noise that is greater than the noise reduction of the scarf.

JET ENGINE INLET DISTORTION SCREEN AND DESCRIPTOR EVALUATION
Acta Polytechnica, 2017 Total pressure distortion is one of the three basic flow distortions (total pressure, total temperature and swirl distortion) that might appear at the inlet of a gas turbine engine (GTE) during operation.

Experimental Investigation of a Forward Swept Rotor in a Multistage Fan with Inlet Distortion [PDF]
International Journal of Aerospace Engineering, 2011 Previous studies of transonic swept rotors in single stage fans have demonstrated the potential of significant improvements in both efficiency and stall margin with forward swept blading.

Effect of Fan on Inlet Distortion: Mixed-Fidelity Approach [PDF]
AIAA Journal, 2018 Inlet distortion is typically encountered during off-design conditions on civil aircraft and in S-ducts in military aircraft. It is known to cause severe deterioration to the performance of a gas-turbine engine. As intakes become shorter, there is an increased interaction between the inlet distortion and the downstream fan.

Influence of inlet distortion on fan aerodynamic performance [PDF]
, 2019 Inlet distortion can lead to loss in efficiency and stability margin of the fan which in return jeopardises flight safety. These aspects driven by inlet distortion are becoming increasingly challenging for the designers of next-generation turbofan engines. With the increase of computational capability and improvements in numerical models, computational

S-duct flow distortion with non-uniform inlet conditions [PDF]
, 2022 Convoluted aero-engine intakes are often required to enable closer integration between engine and airframe. Although the majority of previous research focused on the distortion of S-duct intakes with undistorted inlet conditions, there is a need to ...

An Improved Integral Method for Prediction of Distorted Inlet Flow Propagation in Axial Compressor
International Journal of Rotating Machinery, 2005 An improved integral method is proposed and developed for the quantitative prediction of distorted inlet flow propagation through axial compressor. The novel integral method is formulated using more appropriate and practical airfoil characteristics, with

Effect of inlet distortion with crosswind on aircraft-engine intake aerodynamic performance
Nihon Kikai Gakkai ronbunshu, 2022 This paper describes an experimental study on inlet distortion in the flow ingested to an intake of a ducted fan. Recent high bypass ratio engines tend to shorten the nacelle length for better fuel consumption.
