Investigation on two-phase flow characteristics and oil capture performance of axial oil scoop in aero-engine

Case Studies in Thermal Engineering, 2023
Due to the improvement in the performance of aero-engines and the continuous size reduction, efficient under-race lubrication is becoming more and more important to provide the proper amount of lubricant oil for the main shaft rolling bearings.

Novel design and simulation of curved blade oil scoop with high oil capture efficiency

Chinese Journal of Aeronautics, 2021
Abstract As the load and working environment temperature increasing, high efficiency oil lubrication was urgently needed for the main bearing of aeroengine. However, the low oil capture efficiency of radial oil scoop affects the application of under-race lubrication structure with radial oil collection.

Assessment of the Oil Scoop Capture Efficiency in High Speed Rotors [PDF]

Journal of Engineering for Gas Turbines and Power, 2018
Experimental research was conducted into a scooped rotor system that captures oil from a stationary jet and directs it through passages within the shaft to another axial location. Such a system has benefits for delivering oil via under-race feed to aeroengine bearings where direct access is limited.

Magnetically Guided Synthesis of Anisotropic Porous Carbons toward Efficient CO₂ Capture and Magnetic Separation of Oil [PDF]

ACS Applied Materials & Interfaces, 2023
Conventional synthetic strategies do not allow one to impart structural anisotropy into porous carbons, thus leading to limited control over their textural properties. While structural anisotropy alters the mechanical properties of materials, it also introduces an additional degree of directionality to increase the pore connectivity and thus the flux ...
