Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings. figure 1 , 2 with image 3 , 4 The present invention will be described in detail from two aspects of control flow and assembly structure.

[0030] The control flow of the full-scale vector propulsion device in the present invention is as follows figure 1 Shown. After the airframe attitude and position signals collected by the on-board sensors are transmitted to the on-board computer, the on-board computer calculates the expected value of vector rotation angle and the expected value of motor speed, and transmits them to the motor controller, and the motor controller acts on the control signals respectively. The vector motor and the propulsion motor generate thrust with a vector angle.

Abstract

The present invention proceeds from engineering reality, utilizes existing propulsion technology, and combines the working environment of stratospheric aerostats to propose a simple, effective and reliable full-scale vector propulsion device that can be applied to stratospheric aerostats with various layouts. And using the existing brushless motor and digital steering gear technology, combined with the ground test requirements of the stratospheric aerostat, a low-cost, low-structural load scaled vector propulsion device for the ground prototype of the stratospheric aerostat was proposed. See attached drawing for detailed structure. The device is composed of three major parts, including the propulsion device, the vector rotation mechanism and its connecting mechanism. Among them, the propulsion device provides in-plane thrust, and the vector rotation mechanism provides in-plane steering torque. The connecting part between the two is an industrial-grade transmission device. The onboard control system sends control signals to the propulsion device and the vector rotation mechanism respectively, and the two adjust the speed and vector angle respectively according to the signals, so as to realize the vector propulsion function of the stratospheric aerostat.

Description

Technical field [0001] The invention provides a vector propulsion device for a stratospheric aerostat, which provides an easy-to-implement vector propulsion scheme for the stratospheric aerostat, and belongs to the technical field of stratospheric aerostat design. Background technique [0002] The stratospheric aerostat is one of the important tools for the development of adjacent space. Its low cost, low mobility, long working cycle, harsh working environment and other characteristics require its power system to be simple and reliable. The multi-control surface and multi-control input power system of a conventional airship increases the system complexity and reduces its long-term reliability. Therefore, designing a simple, effective and reliable low-speed drive system has become the main technical problem of the stratospheric aerostat power system. [0003] The stratospheric aerostat is a typical nonlinear system, and its controller design process is more complicated. After the ...
