As one of the most important technologies of the advanced fighter, thrust vector technology can greatly increase the range of controlled angle of attack, and make the fighter easily realize the post stall maneuver. However currently thrust vector technology is achieved by manually manipulating the additional vector stick, which greatly increases the burden on pilots. Thus how to bring the thrust vector control into the automatic control system to reduce the pilot operation burden has become an important engineering problem to be solved. A dynamic inverse design method based on daisy chain allocation method is proposed, which integrates the thrust vector into the automatic control system, thus eliminating the thrust vector manipulating mechanism and reducing the pilot`s operating burden. In addition, the method maximizes the use of the control surface and reduces the use time of the thrust vector, thus effectively reducing the maintenance cost of the engine. The simulation results of vector cylinder maneuver shows that this method can effectively achieve the coordinated control of thrust vector.

Deformation and failure mechanism exploration of surrounding rock in huge underground cavern
Zhenhua Tian,Jian Liu,Xiaogang Wang,Lipeng Liu,Xiaobo Lv,Xiaotong Zhang 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.72 No.2
In a super-large underground with “large span and high side wall”, it is buried in mountains with uneven lithology, complicated geostress field and developed geological structure. These surrounding rocks are more susceptible to stability issues during the construction period. This paper takes the left bank of Baihetan hydropower station (span is 34m) as a case study example, wherein the deformation mechanism of surrounding rock appears prominent. Through analysis of geological, geophysical, construction and monitoring data, the deformation characteristics and factors are concluded. The failure mechanism, spatial distribution characteristics, and evolution mechanism are also discussed, where rock mechanics theory, FLAC3D numerical simulation, rock creep theory, and the theory of center point are combined. In general, huge underground cavern stability issues has arisen with respect to huge-scale and adverse geological conditions since settling these issues will have milestone significance based on the evolutionary pattern of the surrounding rock and the correlation analyses, the rational structure of the factors, and the method of nonlinear regression modeling with regard to the construction and development of hydropower engineering projects among the worldwide.
