Problems solved by technology

If there is no thickening wire rope to press the pressure plate, bottom plate and groove chute, when the engine and the thickening steering gear are not in the same vibration condition, it is easy to cause the trembling of the thickening wire rope and the thickening valve, resulting in improper operation of the thickening valve. Stable, the enrichment steering gear is in a high-frequency vibration environment, which affects the life and reliability of the enrichment steering gear;
[0006] The enrichment valve control mechanism of existing unmanned helicopters has strict requirements on the installation space, especially on small unmanned helicopters, which has relatively large limitations and difficult synchronization adjustment

Abstract

The invention belongs to the technical field of aircraft power device systems, and discloses a linear enrichment steel cable control structure and a control method, which are used for a control mechanism of an engine power device. The linear enrichment steel cable control structure comprises a first support, a second support, a long shaft type fixing structure, a thickening steering engine assembly, a first soft steel wire rope and a second soft steel wire rope. The two ends of the long shaft type fixing structure are slidably connected to the first support and the second support respectively,one end of the enrichment steering engine assembly is fixedly connected to the center of the long shaft type fixing structure, and the first soft steel wire rope is connected to a shaft between the center of the long shaft type fixing structure and the first support. The second soft steel wire rope is connected to a shaft between the center of the long shaft type fixing structure and the second bracket; and stable control of the enrichment channel of the unmanned helicopter is ensured.

Description

technical field [0001] The invention belongs to the technical field of aircraft power plant systems, and in particular relates to a linear thickened steel cable manipulation structure and manipulation method, which are used for the manipulation mechanism of the engine power plant. Background technique [0002] The flight control system of the unmanned helicopter realizes the control of the engine enrichment valve through the valve control mechanism, thereby changing the opening of the engine enrichment valve, and adjusting the air-fuel ratio according to the concentration of the mixture gas required for the engine to realize the control of the unmanned helicopter. Maneuver. [0003] The enrichment valve operating mechanism of the existing unmanned helicopter generally adopts the manipulation structure in which the enrichment steering gear drives a steel cable, and there is no enrichment steel wire rope to compress the pressure plate, the base plate and the grooved chute. It...
