Speech Title: Industrial Digitalization Applications in World-Class Aerospace Companies

Abstract: This plenary presentation will provide an overview of a number of research projects on digital manufacturing which were carried out within world-class aerospace companies such as Airbus and Rolls-Royce. The research projects include digital mock-up, model-based definition and digital workflow in manufacturing. Digital Mock-Up (DMU) project focused on integrating design and manufacturing teams during different phases of aircraft design to reduce concession time. Model-Based Definition (MBD) is based upon the shift to 3D CAD models as a single source of product definition encompassing all the product information and thus eliminating the need for 2D representation.  It is a digital-product model that defines the requirements and specifications of the product. A Model-Based Enterprise (MBE) uses MBD to define the product requirements and specifications instead of paper-based documents as the data source for all engineering activities throughout the product lifecycle. The presentation will provide an outline on digital workflow of complex aerospace manufacturing engineering processes.

Speech Title: Key Technologies of Large-Thrust LOX-Kerosene Engines

Abstract: The large-thrust liquid oxygen (LOX)-kerosene engine represents the development orientation of advanced space main propulsion system and will play a vital role in major space projects such as deep-space exploration, manned lunar mission and space infrastructure construction. This lecture gives a systematic view of key technologies of large-thrust LOX-kerosene engines based on the latest progress in research and product development. Beginning with an overview of the operation principle of staged-combustion LOX-kerosene engine systems and example engines, this speech addresses representative features and challenges of large-thrust LOX-kerosene engines, including rapid dynamic process, extreme operating environment, difficulty in fault diagnosis and high requirements in reliability. To overcome these challenges, several key technologies have been proposed and being gradually broken though. The speech introduces the latest progress in detail and outlines prospects for the future advancement, covering regulation system optimization, structure and flow path design, vibration and instable combustion control, special material and manufacturing techniques, as well as new test and diagnosis approaches.

Speech Title: What will happen when an SRM put into water? The Investigation on the gasous jet underwater

Abstract: When the solid rocket motor(SRM) operation underwater, it will show a quiet different behavior. This lecture will present the results of a series of numerical simulations conducted by the presenter and his team to investigate the performance of SRM, especially the supersonic nozzles on the multiphase flow and propulsion performance. The underwater flow processes of different nozzles spects are simulated under still water, variable depth and over-expanded conditions. Based on the VOF (volume of fluid) multiphase model in the numeric simulation, the influence laws of the divergent types on the nozzle near-field flow structure, flow separation characteristics, and thrust oscillation characteristics are carefully analyzed. It is can be seen that the separation shock structure in the nozzle operating in deep water differ from that in the air, the gas-liquid separation may also occur at the separation point in the divergent section, and the nozzle thrust oscillates on the basis of the full-flow value. There is a dynamic transition of flow separation patterns in the effect of contour type is more pronounced than that of the divergent method of the nozzles having more moderate thrust oscillations than that in the air, also the difference is more significant at greater water depths.

Speech Title: Coupled electrical-thermal-mechanical modelling of responses of CFRP composites after lightning strike and development of novel protective strategy

Abstract: Carbon fiber reinforced polymer (CFRP) composites have been widely utilized in aircraft as load-bearing structures due to their low density, high specific strength and specific stiffness, excellent fatigue resistance and corrosion resistance. However, the extensive use of CFRP composites in airplane structures presents challenges related to lightning strike (LS) threat. Therefore, it is crucial to establish a model for estimation of lightning strike damage of CFRP composites and to develop novel lightning strike protections for CFRP composites in aircraft. This report will address the following aspects:
(1) development of a coupled electrical-thermal-mechanical finite element model to predict the dynamic response and damage evolution in CFRP composites during an LS;
(2) investigation of damage mechanisms in CFRP composites with a dual-layer protection, leading to development of design strategies for LS protection;
(3) exploration of damage mechanisms in CFRP laminates/protections with moisture uptake during an LS;
(4) development of lightweight strategy for excellent LS protection and electromagnetic interference shielding.
