The structural parameters of the liquid sheet represent a significant factor influencing atomization performance, and its measurement is an important part agrochemical study. Currently, predominantly relies on commercial software with manual operation, which labor intensive inefficient. In this study, deep learning methods high-speed photographing were employed to measure hydraulic nozzles different modes. LM-YOLO structure recognition model was constructed recognize perforations. Based...
Spraying drift is a key concern in aerial spraying and relates closely to droplet size. With the growing application of large-load UAVs, plant protection UAVs lack corresponding devices. The rotary cage atomizer, suitable for high-flow spraying, better option UAVs’ needs. A modified rotating atomizer based on AU5000 manned aircraft was designed, with diameters 76 mm, 86 96 106 116 mm. Based IEA-I high-speed wind tunnel, this study investigated impacts different speeds, flow rates,...
Dynamic laser inter-satellite links (LISLs) provide the flexibility of connecting a pair satellites as required (dynamically) while static LISLs need to be active continuously between energy-constrained satellites. However, due LISL establishment time (termed herein setup delay) being in order seconds, realizing dynamic is currently unfeasible. Towards realization LISLs, we first study quantification delay; then calculate end-to-end latency free-space optical satellite network (FSOSN) with...
The self-excited forces and flow fields around a thin plate under stationary sinusoidal non-stationary wind conditions were simulated using the computational fluid dynamics method. differences between force results calculated based on Scanlan's linear flutter theory condition analyzed from perspective of field characteristics. Furthermore, effects different torsional amplitudes plate's investigated. showed that there are significant nonlinear for wind, with large each harmonic component. An...
In this paper, the nonlinear vibration and chaotic motion of axially moving current-conducting thin plate under external harmonic force in magnetic field is studied. Improved multiple-scale method employed to derive strongly subharmonic resonance bifurcation-response equation strip transverse field. By using singularity theory, corresponding transition variety bifurcation, which contain two parameters universal unfolding for system, are obtained. Numerical simulations carried out plot...
The spatial distribution of droplet size and velocity affects the deposition on target. In order to investigate influence different adjuvant pressures in atomization area nozzles, air induction flat fan nozzle IDK120-03, multi-range LU120-03 anti-drift AD120-03 were selected. Phase Doppler Interferometer (PDI) was used analyze compare three nozzles when four typical Maisi, Maidao, Adsee AB-600 Surun sprayed at pressures. results show that volume median diameter has no obvious change along...
(1) Background: Various types of adjuvants are added during application to enhance the spraying effect, but most adjuvant formulations proprietary products, and their exact compositions have not been disclosed. (2) Methods: The spatial distributions droplet sizes velocities generated by atomization different polymer were measured based on phase Doppler interferometer (PDI) measurement method. sub-area statistical method was used quantitatively analyze characteristics at various points below...
Recent advancements in low-Earth-orbit (LEO) satellites aim to bring resilience, ubiquitous, and high-quality service future Internet infrastructure. However, the soaring number of space assets, increasing dynamics LEO expanding dimensions network threats call for an enhanced approach efficient satellite operations. To address these pressing challenges, we propose operations based on multi-layer networking (MLSN), called "SatNetOps". Two SatNetOps schemes are proposed, referred as LEO-LEO...
To study the vortex-induced force (VIF) model of a steel box girder with projecting slab, cable-stayed bridge main span 160 m was taken as research object in this study. First, computational fluid dynamics (CFD) numerical simulation method used to calculate amplitude characteristics vibration (VIV) and calculated results were compared those wind tunnel tests. Then, time–history VIF extracted based on validated results, new mathematical for slab established according residual values between...
