Problems solved by technology

[0002] In the aircraft control system, the rudder surface control power unit is usually controlled by electricity. When the electrical control fails, the power unit can only be fixed at a certain position or swing arbitrarily with the rudder surface under the action of external load, and the pilot loses control over the rudder surface. control, seriously affecting flight safety

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] In order to improve the safety of the aircraft, it is hoped that after the electrical failure, the pilot can still complete the control of the rudder surface and improve the safety of the aircraft. In view of this, the embodiment of the present application provides a control conversion device, see figure 1 , the device consists of:

[0044] Electromagnetic control valve 104, mode conversion mechanism 101, clutch mechanism 102 and mechanical control mechanism 103; above-mentio...

Abstract

The embodiment of the invention provides a control conversion device and a control system. When a mode conversion mechanism receives a first signal of a solenoid control valve, the mode conversion mechanism is in an electric control state; when a clutch mechanism receives a second signal of the solenoid control valve, there is a first space between the clutch mechanism and a mechanical control mechanism, and the first space guarantees that mechanical motion of the mechanical control mechanism does not cause linkage of the clutch mechanism; when the mode conversion mechanism does not receive the first signal of the solenoid control valve, the mode conversion mechanism is in a mechanical control state; and when the clutch mechanism does not receive the second signal of the solenoid control valve, the clutch mechanism sticks to the mechanical control mechanism, and the mechanical motion of the mechanical control mechanism causes linkage of the clutch mechanism. After electric control fails to work, the working state of the mode conversion mechanism is converted, and the clutch mechanism is enabled to stick to the mechanical control mechanism; and therefore, control surface control isconverted from electric control to mechanical control, and the safety of an aircraft is enhanced.

Description

technical field [0001] The present application relates to the technical field of mechanical control, in particular to a control conversion device and a control system. Background technique [0002] In the aircraft control system, the rudder surface control power unit is usually controlled by electricity. When the electrical control fails, the power unit can only be fixed at a certain position or swing arbitrarily with the rudder surface under the action of external load, and the pilot loses control over the rudder surface. control, seriously affecting flight safety. In order to improve the safety of the aircraft, it is hoped that after the electrical control fails, the pilot can still complete the control of the rudder surface to improve the safety of the aircraft. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a control conversion device and a control system, so as to improve the safety of the aircraft. The spec...
