2results about How to "Implement mode switching" patented technology

The application provides a four-legged robot auxiliary crossing mechanism, which comprises a base, a trunk and a rotor; two arc-shaped sliding rails are symmetrically arranged on the base, and each sliding rail is provided with a positioning slot; the trunk comprises a rotating motor, a rotating shaft, positioning pins arranged at the bottom of both sides of the trunk, electromagnets arranged above the positioning pins and the sliding rails below the positioning pins; the rotating motor is used for driving the rotating shaft to rotate the trunk above the base with the center as the axis; when the positioning pins rotate to the position of the positioning slots, the positioning pins fall into the positioning slots and are locked in the positioning slots; the electromagnets are used for taking out the positioning pins from the positioning slots; and the rotor is used for generating upward lift force; the application provides simple trunk mechanical structure, limited rotation on the base, mode switching and relatively small technical difficulty; and in the crossing or flying mode, the positioning and locking device is used to improve the reliability of the mechanism.

This invention relates to the field of gas turbine engine technology, specifically to a turboshaft engine aerodynamic adjustment system and its control method. The turboshaft engine aerodynamic adjustment system includes: a compressor; a particle separator with a first air intake on its inner flow channel wall; a first air conditioning flow path, one end of which is connected to the compressor and the other end to the first air intake, the first air conditioning flow path being adapted to adjust the flow rate of compressed air in the introduced airflow channel to adjust the flow field of the particle separator; a power turbine guide vane with a second air intake; and a second air conditioning flow path, one end of which is connected to the compressor and the other end to the second air intake, the second air conditioning flow path being adapted to adjust the flow rate of compressed air introduced into the inter-vane passage of the power turbine to adjust the flow function of the power turbine. The turboshaft engine aerodynamic adjustment system provided by this invention can actively adjust component characteristics according to changes in flight conditions and environmental factors, improving engine performance and environmental adaptability.
