A traditional accelerator and a total distance rod are omitted, the control structure of the aircraft is simplified, a pilot can more quickly adapt to the operation requirements in different flight states by simplifying control logic, and the potential error risk caused by control mode switching is reduced.

The application discloses an insect exoskeleton morphological layup composite panel, a sandwich structure and a preparation method. The sandwich structure comprises two pieces of bionic layup composite panels and a piece of aramid honeycomb core layer. The bionic layup composite panel draws lessons from the spiral stacking microstructure of the insect exoskeleton, the layup design considers the symmetry and balance requirements of the composite material, a fixed rotation angle is introduced between adjacent fiber layers, and the rotation angle is taken as a period of 180 degrees, and after a plurality of periods are laid and heat-pressed and cured, the bionic layup composite panel is obtained. The bionic layup design effectively reduces the interlaminar shear stress of the composite material, weakens the inherent anisotropy of the composite material, and improves the transverse bearing capacity and impact resistance. The bionic layup composite panel and the aramid honeycomb core layer have the advantages of high specific strength, high specific stiffness, impact energy absorption, vibration and noise reduction, electromagnetic shielding and the like, and a structure and function integrated material with more excellent comprehensive performance is obtained, and the structure and function integrated material is expected to be widely used in main load-bearing structures of various spacecrafts.

The application relates to the technical field of unmanned aerial vehicle fluid spraying, and discloses a single-motor-driven fluid spraying device, which comprises a speed reduction motor, a long light shaft, a driving bevel gear and two short parallel light shafts.The single-motor-driven fluid spraying device can efficiently decompose single-axis rotating power into two routes of vertical rotating power through the cooperation between the components, and the two short light shafts automatically obtain opposite rotating directions.This transmission mode omits the complex worm gear or multi-stage gear reversing mechanism in the traditional scheme, greatly simplifies the transmission chain, effectively improves the power transmission efficiency, significantly reduces the overall volume and weight of the device, reduces the noise and vibration in the transmission process, and enables the device to better adapt to the compact and light mounting requirements of the unmanned aerial vehicle.

This invention discloses a jet-based rotor flow control system and method, relating to the field of helicopter aerodynamics. It includes an engine bleed air inlet, an air filter, a one-way valve, a high-pressure air source chamber, a pressure reducing valve, and a proportional valve, connected sequentially via pipes.
