Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Optimization in Conceptual Design of a BWB UAV Using an Adaptive Kriging‐Based Surrogate Model

Engineering Reports, Volume 8, Issue 2, February 2026.
An adaptive Kriging‐based framework for Blended Wing Body UAV optimization is presented. The exploitation‐oriented strategy yields a 14.5% range improvement, while sensitivity analysis identifies fuel mass as the dominant parameter for efficient conceptual design. ABSTRACT To improve optimization efficiency in the conceptual design of Blended Wing Body

Development and Airworthiness Certification of the Ti6Al4V Inlet Casing Inner Forging

Defence Science Journal, 2023
The inlet casing inner has manufactured using Ti-6Al-4V alloy through a closed die-forging route. It undergoes cyclic loads in addition to operating in extreme conditions in high-temperature environments. The demanding mission requirement of these engines necessitates the inlet casing inner to be flawless throughout its life cycle while retaining its ...

Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.

Requirements Management Applied in Airworthiness Certification in the Civil Aircraft

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The civil aircraft certification is the process, which indicates whether aircraft design complies with airworthiness regulations, or not. In recent years, requirements management has been gradually implemented in civil aircraft design, showing a method, which can implement a series of stakeholder, needs or expectation including ...
