Embodiment Construction

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

[0030] In the present invention, the control flow of the full-scale vector propulsion device is as follows: figure 1 shown. After the fuselage attitude and position signals collected by the onboard sensors are transmitted to the onboard computer, the onboard computer calculates the expected value of the vector rotation angle and the expected value of the motor speed, and transmits them to the motor controller, and the motor controller acts on the control signals respectively. A vector motor and a propulsion motor, thereby generating thrust with a vector angle.

[0031] In the present invention, the control flow of the scaled vector propulsion device is as follows: figure 2 shown. After the fuselage attitude and position signals col...

Abstract

The invention provides a simple effective and reliable full-dimension vector propelling device capable of being applied to stratosphere aerostats in various layouts through proceeding from the reality, using the existing propelling technology and combining the work environment of the stratosphere aerostats. In addition, the invention provides a low-cost and low-structure-load stratosphere aerostat ground model machine scaled vector propelling device through using the existing brushless motor and digital steering engine technology and combining the ground test requirements of the stratosphere aerostats. A detailed structure is shown in the accompanying drawing. The device totally consists of three major parts including a propelling device, a vector rotating mechanism and a connecting mechanism, wherein the propelling device provides in-plane thrust, the vector rotating mechanism provides an in-plane steering moment, a connecting part between the propelling device and the vector rotating mechanism is an industrial stage transmission device, an onboard control system respectively sends control signals to the propelling device and the vector rotating mechanism, the propelling device and the vector rotating mechanism respectively carry out rotating speed and vector angle regulation according to the signals, and further, the vector propelling function of the stratosphere aerostats can be realized.

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 developing adjacent space. Its low cost, low maneuverability, long working cycle, and harsh working environment require its power system to be simple and reliable. However, the multi-control surface and multi-control input power system of the conventional airship increases the complexity of the system and reduces the reliability of its long-term work. Therefore, designing a simple, effective and reliable low-speed drive system has become a major technical problem in the power system of the stratospheric aerostat. [0003] The stratospheric aerostat is a typical nonlinear system, and its controller design process is relativel...
