In large civil aircraft manufacturing, a time-consuming post-production process is the non-destructive inspection of wing panels. This work aims to address this challenge and improve the defects’ detection by performing automated aerial inspection using a small off-the-shelf multirotor. The UAV is equipped with a wide field-of-view camera and an ultraviolet torch for implementing non-invasive imaging inspection. In particular, the UAV is programmed to perform the complete mission and stream video, in real-time, to the ground control station where the defects’ detection algorithm is executed. The proposed platform was mathematically modelled in MATLAB/SIMULINK in order to assess the behaviour of the system using a path following method during the aircraft wing inspection. In addition, two defect detection algorithms were implemented and tested on a dataset containing images obtained during inspection at Airbus facilities. The results show that for the current dataset the proposed methods can identify all the images containing defects.

Purpose The purpose of this paper is to construct a grey clustering model based on the nonlinear whitenization weight function and to assess the safety of civil aircraft by using a quantitative method. Design/methodology/approach According to the running stage of civil aircraft safety assessment issues, first the civil aircraft safety evaluation index system is constructed by using a qualitative method. Taking the information duplication between indicators, the grey relational analysis method is used to filter the key indicators, then the grey clustering evaluation model of nonlinear whitening right function is built to evaluate the safety of civil aircraft and the algorithm steps of the evaluation model are given. Finally, the model is validated by collecting the parameters of nine different civil aircrafts at home and abroad. Findings The results show that the safety level of different types of aircraft is different due to the different index parameters, and to some extent, explain the rationality and scientificity of the method proposed in this paper to solve the problem. Practical implications This paper gives a complete set of security assessment methods, which can be used to evaluate the security of civil aircraft in the operational phase quantitatively, scientifically and reasonably. Furthermore, it can be extended to other complex system security or stability assessment issues. Originality/value It not only provides the supplement and perfection of the safety assessment method in the theoretical system to a certain extent, but also provides a theoretical guidance to solve the problem of civil aircraft system safety assessment of civil aircraft manufacturing enterprise all over the world. At the same time, the nonlinear grey clustering evaluation model constructed in this paper is an improvement of the traditional model, which is, to some extent, the improvement of the grey clustering evaluation theory.

The fundamental basis of the research is the analysis of the aircraft fleet of leading European and Russian airlines in order to determine the main trends and prospects for the development of the European aircraft Corporation "Airbus SE" in the context of macroeconomic instability caused by the impact of the COVID-19 pandemic. According to European experts, by the end of 2020, the decline in production in the civil aircraft segment will reach 40% - 50%, which is the worst result in the history of the industry. During the period from 2009 to 2019 Corporation "Airbus SE" increasing its production capacity, which led to the market new and modernized samples of aviation equipment, has expanded its influence in the market. The analysis of the impact of the 2020 crisis caused by the COVID-19 pandemic should become the basis for developing anti-crisis measures not only by the leadership of the European Union, but also by the governments of all States that are aircraft manufacturing powers.

Inventory control plays a crucial role for civil aircraft in reducing production cost to improve the competitiveness. Aiming at the special requirements of aircraft manufacturing industry, we propose a solution to classify the material instead of ABC inventory control. In order to balance economy and reliability, we build a new criterion system to classify the aircraft material into nine categories. We investigate the Support Vector Machine (SVM) method to classify the material for it has been proved very powerful and effective in establishing classification model with small sample, nonlinearity, high dimension and local minima. The choice of corresponding parameters, the choice of the training set, and the choice of the SVM kernel highly affect the performance of the classification. The study was done to determine the appropriate kernel function and to optimize SVM’s parameters for the classification of civil aircraft materials. Research results prove the validity of the classification model by the software implementation.

AbstractChina's accession to the WTO in 2001 is widely accepted as a landmark event for the multilateral trade system and for the country. The large-scale WTO-plus commitments have nevertheless received unceasing criticism and discussion. This article is concerned with the resulting policy implications for the Chinese initiative to become a global producer of large civil aircraft at the next stage of development. A real-life case study is expected to provide robust evidence for inquiring whether China and emerging economies alike can smoothly advance up the global value chain while honouring their WTO obligations in good faith. The article confirms the widespread opinion that there are vast legal uncertainties ahead for China throughout this journey, and for that reason, a rigorous market-orientation effort is needed to strengthen its ability to compete in the commercial aviation sector.
