Problems solved by technology
At present, the control power of the electromechanical servo system of the launch vehicle is powered by the battery of the central control system. After separation, the control power will be cut off, resulting in failure to work.
Therefore, if the electromechanical servo system is required to continue to work after separation, the electromechanical servo system must be redesigned

Embodiment Construction
[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0026] Such as figure 1 As shown, the solid carrier rocket with a typical two-stage engine is used as an example to illustrate the electromechanical servo system and aircraft with simple attitude control function of the present invention. Stage engine 103 and payload 104 are formed in series. When the rocket is launched, first the primary engine 101 works, and after the work is over, the rocket primary engine 101 is separated from the rocket secondary engine 103 through the interstage section 102, then the secondary engine 103 works, and after the secondary engine 103 is finished working, it is separated from the payload. 104 separates, and payload 104 executes the flight mission.
[0027] In the actual launching process, when the primary engine 101 and the secondary engine 103 are just separated, due to the residual thrust of the primary engine 101, the...

The invention provides an electromechanical servo system with a simple attitude control function. The electromechanical servo system comprises an electromechanical actuator, a servo control driver, a servo power source and a power source converter, the servo control driver is used for receiving a control instruction sent by a central control system of an aircraft and driving the electromechanical actuator, the servo power source powers the whole electromechanical servo system, and the power source converter is used for converting high-voltage direct current of the servo power source to acquire conversion control current for controlling the servo control driver after the servo control driver is separated from the central control system of the aircraft. By arranging the power source converter, after being separated from the central control system of the aircraft, the power source converter converts the high-voltage direct current of the servo power source to acquire the conversion control current for controlling the servo control driver to enable the electromechanical servo system to continue working, an engine after separation is pushed to deviate for a certain angle, and the aircraft on an upper layer is prevented from being chased and attacked.
Description
technical field [0001] The invention relates to the field of aircraft, in particular to an electromechanical servo system with a simple attitude control function and an aircraft. Background technique [0002] The closed-loop system for the flight control of the launch vehicle and its payload aircraft is generally referred to as an electromechanical servo system. One of the typical applications of the electromechanical servo system is to swing the nozzle of a liquid engine or a solid engine to achieve thrust vector control and complete the control of the attitude of the launch vehicle. control. Solid rocket motors use solid combustible grains as fuel. They have the advantages of long storage time, good maintainability, short preparation time, and flexible use. They are currently one of the mainstream rocket development directions in the world. Correspondingly, the closed-loop control electromechanical servo system of the rocking solid rocket motor nozzle is also a necessary ...
