Embodiment Construction

[0039] The inventive concept of the disclosed UAV engine control system and its refitting method is: the steering gear controls the engine controlled quantities such as blade angle, fuel volume and power by controlling the steel cable under the control of the steering gear controller. control, as much as possible to make the working state of the UAV engine the same as that of the manned machine; further, in order to make the control of the UAV engine more accurate and fast, the present invention measures the elongation of the steel cable when the engine is in different gears The amount, and the elongation of the steel cable is converted into the angular displacement of the rocker arm of the steering gear, which further ensures that the working state of the UAV engine is the same as that of the manned aircraft.

[0040] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail be...

Abstract

The invention provides an unmanned aerial vehicle engine control system and a modifying method thereof. An engine controlled by the unmanned aerial vehicle engine control system is controlled by a control steel cable. The unmanned aerial vehicle engine control system comprises at least one control steel cable, at least one steering engine controller and at least one steering engine, wherein the control steel cables are connected with the engine; a steering engine rocker arm is arranged on each steering engine, is connected with the corresponding control steel cable, and is connected with the engine through the corresponding control steel cable; and each steering engine is further connected with a steering engine controller. The invention further provides a modifying method of the unmannedaerial vehicle engine control system. Controlled variables such as a blade angle, a fuel amount and power of the engine are controlled by the steering engines through the control steel cables under the control of the steering engine controller, and the working state of an unmanned aerial vehicle is the same as the working state of a manned aerial vehicle as much as possible.

Description

technical field [0001] The present disclosure relates to the technical field of aircraft power control, more to the technical field of general aircraft engine control, and in particular to an unmanned aerial vehicle engine control system and a refitting method thereof. Background technique [0002] With the rapid development of today's logistics industry, the traditional form of land logistics can no longer meet the needs of industry development. Most logistics companies have already used aircraft as a means of transportation. The P-750XL general-purpose aircraft produced by Pacific Aerospace of New Zealand is very suitable for the logistics industry as a transport aircraft because of its short take-off and landing distance, long battery life, and heavy load. [0003] Due to the disadvantages of high operating costs of manned aircraft and limited operation by airport weather conditions, changing the P-750XL to a UAV is a good way to improve. But the problem is how to make ...
