A Combined and Separated Stratospheric Vehicle System

Abstract

The invention provides a combined-separate stratospheric aircraft system scheme. The system scheme mainly comprises a high-altitude balloon, a solar powered unmanned air vehicle and a connecting rope, wherein the high-altitude balloon comprises a bag main body and a cable net structure which is outside the bag main body; and the solar powered unmanned air vehicle is the core of the whole platform and mainly comprises a structure subsystem, an energy subsystem, an avionic flight control subsystem, a propelling subsystem and a loading subsystem, which are arranged on a stabilizer of the solar powered unmanned air vehicle. According to the combined-separate stratospheric aircraft system scheme provided by the invention, the platform takes off through the high-altitude balloon; and the high-altitude balloon is separated from the solar powered unmanned air vehicle through an explosion device after the platform reaches a fixed flying height. The solar powered unmanned air vehicle flies for a long time through parts carried on the unmanned air vehicle and returns to a fixed point through its avionic flight control subsystem after the flying task is finished. Through the adoption of the combined-separate stratospheric aircraft system scheme provided by the invention, the performance of the solar powered unmanned air vehicle during executing the flying task can be greatly improved.

Description

[0001] 1. Technical field: [0002] The invention provides a combined and separated stratospheric aircraft system solution, which belongs to the technical field of aerospace platform systems. [0003] 2. Background technology: [0004] With the further expansion of the field of aerospace technology, the stratospheric vehicle used for the combination of aviation and spaceflight has become the focus of research in various countries. Compared with traditional aircraft, the advantages of low-speed stratospheric aircraft are: (1) long time in the air and sustainable work. It is easy to obtain long-term and uninterrupted intelligence and data, and respond quickly to emergencies in a timely manner. (2) Wide coverage. A stratospheric vehicle flies at a higher altitude than a conventional aircraft and therefore covers a wider area than a conventional aircraft. (3) Strong survivability. Because the main components of balloons or blimps and some low-speed drones are made of non-metall...

Problems solved by technology

However, the problem with the existing research is that the solar-powered drone rises from the ground to a predetermined flight height, which is generally 20km, and usually takes more than a day to complete. The problem brought about by the slow ascent speed is the poor quick response ability, which in turn affects its execution. mission performance
