Abstract This study presents a new design for multi-degree-of-freedom underdriven mechanism. The aim is to achieve efficient bionic motion of sea turtle hydrofoil with multi-degrees-of-freedom using single drive source. focuses on the kinematic characteristics hydrofoil. and modeling are completed by accurately extracting fitting contours leading trailing edges article detailed data analysis performance through pool experiments combined CCD camera shots. experimental results reveal that...
We study the regularity of $p$-Gauss curvature flow with flat side. In our previous paper(arxiv:2403.12292), we obtained interface, namely boundary part. this paper, convex hypersurface near interface.
Positioning accuracy affects flight safety. In this study, aiming to address the issue of how ground station deployment multilateration, an optimal strategy based on real terrain factors is proposed. This method comprehensively considers practical geographical factors, constructs a grid model, and generates initial candidate sites through model. Subsequently, Xdraw algorithm utilized assess coverage stations conduct preliminary screening sites. Then, combination computed by integrating GA....
The aerodynamic characteristics of the close formation flight are numerically analyzed to facilitate a greater understanding vortex effects between UAVs and technically support application for UAVs. single UAV calculated, results which used as reference variation values in comparison with flight. leading on trailing two analyzed. position where obtains maximum lift-to-drag ratio is defined optimal position. Based position, three different types formations designed explore preliminary...
A concept of VTOL power unit which based on gas-driven fan was presented in this paper. And its aerodynamic characteristics designed point were numerically investigated. The results shown that it has a relatively good thrust and lift can be used as device for aircraft. 2D flow indicated the intake greater influence unit, main influencing factors are rounding radius height. 3D numerical simulation further demonstrated effect In paper, δ is equal to 0.568 when H 0. 382D, even under condition...
As a propulsion system for vertical take-off and landing (VTOL) aircraft, the gas-driven fan has received some attention in recent years due to its simple mechanical structure good performance. During operation of system, core turbofan exhaust is directed tip turbine drive ducted obtain thrust, louvered vector device used achieve lift/thrust switching. However, linkage characteristics guide vanes device, area will gradually change with deflection vanes. This may cause uncertain effects on...
