Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The amount of oil required for a micro turbojet engine is 0.1kg / h. According to the design requirements and characteristics of the turbojet engine control device, the aeroengine can run stably and reliably under any environmental conditions and any working conditions, and its performance benefits can be fully utilized. The realization of fuel supply quantitative and good starting control of the engine directly affects the performance of the engine, and is related to whether the engine can run reliably and efficiently in the expected working state. Aiming at the micro turbojet engine, the present invention proposes a novel control device which uses a fuel gear pump to independently complete the dual functions of establishing oil pressure and regulating oil volume and a control method suitable for starting the micro turbojet engine.

Abstract

The invention discloses a control device for a microminiature turbojet engine and a starting control method thereof. The device comprises a rotating speed sensor for collecting the rotating speed of an engine, a temperature sensor for collecting exhaust temperature, a switch controller, a throttle controller, an electronic control unit (ECU) and an executing mechanism, wherein the executing mechanism comprises a starting motor, a hot piston, a propane gas valve, a fuel protective valve and a fuel gear pump. The control method comprises the following steps: the ECU monitors the working state of the engine through the sensor, and outputs a pulse-width modulation signal to a power drive circuit to control the starting motor, the hot piston, the propane gas valve, the fuel protective valve and the fuel gear pump so as to complete starting control to the engine; functions of establishing fuel pressure and adjusting fuel quantity can be realized by the fuel gear pump after starting of the engine is completed; and fuel can be accurately supplied to ensure that the engine operates in an expected working state. The device can be used for a microminiature delivery vehicle, and the executing mechanism of the device has the advantages of simple structure, small volume and light weight, and easily realization of reliable and efficient control to the engine.

Description

Technical field: [0001] The invention relates to a control device for an engine and a starting control method thereof, in particular to a control device for measuring a micro turbojet engine and a starting control method thereof, and belongs to the technical field of aero-engine fuel control. Background technique: [0002] The working purpose of the aero-engine control device is to make it run stably and reliably under any environmental conditions and any working state, and to give full play to its performance benefits. Most of the traditional turbojet engines use mechanical hydraulic control devices, and their actuators use electro-hydraulic servo valves to control the pressure difference of the follower pistons to change the inclination angle of the swash plate of the oil pump. With the advancement of science and technology, stepping motors have begun to It is used for the actuator to control the opening of the oil valve to achieve the function of controlling the amount of...
