Achievements

The 2016 International Conference in aerospace for young scientists was held in Beijing, China, from 11 to 12 November. More than 100 scholars from over 20 universities and research institutions around the world attended the conference. 182 papers were submitted during this conference, and 132 papers, including 35 by Hong Kong and foreign students, and 32 by other domestic colleges and universities, were accepted after strict review.

A total of 104 participants and eight well-known international experts made a series of splendid reports on their own research. Professor Jose Herskovits from the Federal University of Rio de Janeiro and Professor Dianzi Liu from the University of East Anglia made a wonderful academic report at the opening ceremony. In addition, six well-known scholars were invited to make reports under each sub-forum. The sub-forum topics covered a variety of theoretical and empirical issues in relation to mechanics, aircraft design, power control and etc.

This conference is closely focused on the international academic frontier, providing a platform for worldwide aviation young scholars to present scientific research and their progress. It offers an opportunity of face-to-face interaction for young scholars from different regions to discuss about new ideas. Accordingly, it will fully expand the scope of academic communication for young scholars, and promote international academic exchange in the field of aviation.

Speakers at ICAYS 2016

Opening Ceremony Report 1


Title: A general feasible points approach for inequality constraints and
complementarity conditions in continuous mathematical programming.
Time: 2016.11.12.10:00.
Place: Ruxin conference center.
Reporter: Jose Herskovits

Brief introduction to the reporter:
Jose Herskovits is a Senior Professor at COPPE, the Graduate Scholl of Engineering of the Federal University of Rio de Janeiro, UFRJ, where he works since 1977. He is also advisor at IME, the Military Institute of Engineering. Jose Herskovits works on the development of Numerical Methods for Optimization and their applications in Mechanical Engineering, mainly in Structural Optimization and Stress Analysis involving variational inequalities.
Brief Introduction to the Report:
In this talk, we present a numerical approach for these problems based on perturbed Newton like iterations. The magnitude of this perturbation is precisely determined in order to obtain a search direction that is feasible as well as descent with respect to a suitable potential function. A descent and feasible sequence is obtained by means of a line search procedure.

  

Opening Ceremony Report 2

Dr Dianzi Liu is a Lecturer in Engineering at the University of East Anglia (UEA), UK and Associate Chair Professor at the Beihang University, China. His current research interests include Composite Aerostructures, Structural Analysis, Simulation and Optimization Driven Designs, Implementation and Application of Optimization Algorithms/Techniques in the Mechanical, Manufacturing and Aerospace Engineering.
Brief Introduction to the Report:
In this talk, topology optimization of aircraft fuselage section is performed in order to provide a scientific basis for finding a rational structural layout. A detailed finite element model for the fuselage structure including the barrel, floors, ring frames and struts is built.

  

Mini Symposium Report

Solid Mechanics Venue


Title: Tackling the interfacial issues in fiber-metal laminated composites
Time: 2016.11.12 13:30.
Place:Conference Room 3 of New Main Building.
Reporter: Hong Kong University of Science and Technology,Jinglei Yang.

Brief introduction to the reporter:
Dr Jinglei Yang is currently an Associate Professor in the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology (HKUST). His research interests include multifunctional composites/structures/coatings and mechanics.
Brief Introduction to the Report:
Fiber-metal laminates (FMLs) have attracted much attention because of their successful applications in A380 and Boeing 787 with excellent combined properties from both metals and fiber reinforced plastics. However, to seamlessly integrate these two materials together is a challenge for long-term service. In this talk, Dr Yang will introduce his research on the development of two types of FML structures: carbon fiber reinforced plastic (CFRP) tubular structure with Ti alloy as liner pipe using innovative filament winding approach, and impact resistant FML flat structure using Vacuum-Assisted Resin Transfer Molding (VARTM) method.

Man-Machine and Environmental Engineering Venue


Title:Forced synchronization of hydrodynamically self-excited jets and flames.
Time: 2016.11.12 13:30.
Place:Conference Room 7 of New Main Building.
Reporter:Hong Kong University of Science and Technology,Larry Li.

Brief introduction to the reporter:
Dr Larry Li is an Assistant Professor in the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology (HKUST). Prof Li’s research focuses on flow instability, combustion and thermoacoustics, with applications ranging from aircraft propulsion to spray painting.
Brief introduction to the report:
In the analysis of thermoacoustic systems, a flame is usually characterised by the way its heat release responds to acoustic forcing. This response depends on the hydrodynamic stability of the flame. If a hydrodynamically globally unstable flame really is insensitive to forcing at other frequencies, then it should be possible to weaken thermoacoustic oscillations by detuning the natural frequency of the hydrodynamic mode from that of the acoustic modes. In this talk, I will present results from simple experiments designed to test this idea.

  

Aerospace Power and Propulsion Venue


Title:On Stabilities of Rotation Detonation.
Time: 2016.11.12 13:30.
Place:Conference Room 5 of New Main Building.
Reporter:Tsinghua University,Bing Wang

Wang Bing, Distinguished researcher (teaching and research series), born in February 1977 in Hebei Tangshan. He teaches and does research work in School of Aeronautics and Astronautics of Tsinghua University since 2005 . Prof Wang’s research focuses on the advanced mechanism of ignition and turbulence two-phase combustion process, law and control mechanism of advanced engine extreme conditions (National Natural Science Foundation of China, 973, the national major projects funded).
Brief introduction to the report:
The experimental test and comparative analysis of rotating detonation wave motion stability in a laboratory scale hydrogen/air rotating detonation engine (RDE) are reported in this paper. The pressure signals are obtained at the different circumferential and axial positions of the RDE under the equivalence ratio of 1.01 and 1.52. The stable propagation, mode switching, direction inverse and hetero-rotating are produced during the working process of RDE.

  

Special Activities

On the night of November 12th, the dinner party of the ICAYS with the theme of “611 night” was held in the restaurant of Training Center of Beihang University. In this party, Scholars from different countries got together and had good communication while enjoying gourmet meals. They could thus exchange acdemic thoughts in a more relaxing and informal atmosphere.

During the dinner, the deputy director of AVIC CHENGDU AIRCRAFT DESIGN & RESEARCH INSTITUTE expressed his expectations to the young scholars participated in ICAYS and encouraged them to continue to make contributions to the development of aviation industry. Prof. Guiping Lin, secretary of the party committee of School of Aeronautic Science and Engineering attended the above mentioned activities.
