Biomass is important in monitoring global carbon storage and the cycle, which quickly accurately estimates forest biomass. Precision forestry modeling place high requirements on obtaining individual parameters of various tree species complex stands, studies have included both overall stand trees. Most existing literature focuses calculating species’ biomass a single stand, there little research stands. This paper calculates stands by combining multispectral light detection ranging (LIDAR)...
ABSTRACT The cycloidal propeller for a Micro-Aerial Vehicle (MAV)-scale cyclogyro in hover was studied using 2D Reynolds-averaged Navier-Stokes equations solver. effects of the blade dynamic stall, parallel Blade Vortex Interaction (BVI), inflow variation and flow curvature were discussed, based on results numerical simulation. from Computational Fluid Dynamics simulation indicated that rotor is actually performing pitching oscillation, if observed moving reference frame. stall vortices shed...
In recent years, a lot of research work has been carried out on the cycloidal rotors. However, it lacks thorough understanding about effects blade platform shape hover efficiency rotor, and knowledge how to design blades. This paper presents numerical simulation model based Unsteady Reynolds-Averaged Navier–Stokes equations (URANSs), which is further validated by experimental results. The aspect ratio taper are analyzed, shows that rotors with same chord length have quite similar performance...
Purpose This paper aims to investigate the mechanisms lying behind cycloidal rotor under hovering status.
The cycloidal propellers for MAV scale cyclocopter in hovering status were studied this paper based on the URANs solver using 2D, 2.5D, 3D half blade and full model. results from all numerical models validated with experimental results. It was found that 2.5D model cannot produce more accurate than 2D model, hence employed to discuss rotor infinite span. also indicates produces same as but is efficient simulation of finite (3D model) span (2D compared. indicated large pitching amplitude,...

Purpose This paper aims to investigate the impact of aerofoil camber on performance micro-air-vehicle-scale cycloidal propellers. Design/methodology/approach First, experiments were conducted validate numerical methodology. After that, three turbulent models compared select most accurate one. Then, 2D simulation was carried out 11 aerofoils with different cambers, including five cambered aerofoils, one symmetrical and inverse aerofoils. The are about chord line corresponding ones. Findings...
Dual layer coatings CrNx and Ni-Fe alloy have been developed for metallic interconnects application by a combined approach. The was deposited on ferritic stainless steel using multi-arc ion plating, the coating electroplated coated subsequently. After oxidation at 800 °C in air 5 h, multi-layer scale composed of NiFe2O4, Cr2O3, Ni-Fe-Cr from outside to inside formed CrNx/substrate with 1.6 μm thick Ni-32 at%Fe coating. Further led decomposition layer, but no pores could be observed near...
Model driven architecture (MDA) is a method which can build abstract model for business logic, and generate the ultimate complete application based on model. Procedure blueprint program process representation describe behavioral of software formally. In this paper, we give Web service development MDA procedure blueprint. This might be useful in with semantic information from extended diagram.
Abstract The numerical simulations for cycloidal propellers based on five aerofoils with different thickness are presented in this paper. CFD simulation is sliding mesh and URANS. results of indicates that all test cases share similar flow pattern. There leading edge vortex trailing-edge due to blade dynamic stall. Interaction between the vortices shed from upstream downstream can be observed. variation relative inflow velocity downwash rotor cage. These factors result large fluctuations...
Cycloidal rotor is a whose blades pitch around the pitching axis and revolve shaft that parallel to blade. It can generate omni-directional thrust with high efficiency. In this paper, numerical simulation models were validated by wind tunnel experiments. Then physics of cycloidal in forward flight was studied. The effects blade number advance ratio qualitatively discussed based on results. Results analysis indicate more will result smoother force curve, so there be lower vibration. However,...
Accurate estimation of forest individual tree characteristics and biomass is very important for monitoring global carbon storage cycle. In order to solve the problem calculating various species in complex stands, we take terrestrial laser scanning data, unmanned aerial vehicle-laser multispectral data as sources extract spectral characteristics, vegetation index texture height diverse areas through classification species. Based on random (RF) algorithm, extracted features were superimposed...
