Shock and Vibration, Volume 2025, Issue 1, 2025.The dual‐rotor structure was usually adopted in aeroengine for the sake of higher efficiency, where the high‐pressure (HP) rotor and the low‐pressure (LP) rotor are coupled together through an intershaft bearing. For the convenience of manufacturing and maintenance, the bolt connections are widely adopted in high‐power rotors to fasten together ...

Data augmentation for predictive maintenance: Synthesising aircraft landing gear datasets
Engineering Reports, Volume 6, Issue 12, December 2024.This article evaluates how effectively time series data can be synthesised using Gretel.AI models, trained on data harvested from Aircraft Landing Gear systems. This method can be used to anonymise data for public research in predictive maintenance for aircraft and augment existing datasets.

Theoretical investigation of acceleration of a turbojet engine
, 1947 The failure of turbojet aircraft propulsion units to accelerate rapidly to high thrust operation when emergencies arise in slow speed flight has restricted their use in aircraft applications, and has also concentrated considerable attention upon their acceleration characteristics in an effort to produce better results.
