Gas turbine exhaust nozzle [PDF]
, 1973 An elongated hollow string is disposed in an exhaust nozzle combustion chamber and communicates with an air source through hollow struts at one end. The other end of the string is bell-mouth shaped and extends over the front portion of a nozzle plug. The

Modelling and Simulation in Engineering, Volume 2025, Issue 1, 2025.A rotor in motion transfers energy to the fluid, comprising not only the essential axial component but also a rotating segment that contributes to propeller thrust. This study scrutinizes the effects of integrating swirl recovery vanes (SRVs) with the eight‐bladed SR3 rotor for transonic flows in a tractor prop configuration, examining setups both with

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.

Thermal Defects of Avionic Turbojet Engines
Research Works of Air Force Institute of Technology, 2016 AbstractThe paper analyzes the most frequent reasons associated with operation of avionic turbojet engines (ATE) and leading to initiation of thermal defects affecting turbine units. These reasons are illustrated with examples of gradual deteriorations revealed on surfaces of turbine parts and subassemblies and defected during endoscopic examinations ...
