Natural heat and sail driven aerostat system with controllable track

Abstract

The invention relates to a natural heat and sail driven aerostat system with a controllable track. An upper covering and a lower covering are welded to form a main air bag which is filled with the air. As the outer surface of the upper covering and the outer surface of the lower covering are coated with heat control coatings, solar radiant heat and infrared radiant heat of the surface of the earth are absorbed, so that the temperature of the air in the main air bag is raised and floating force is generated; an air valve is installed on the top of the main air bag and started and closed by receiving instructions of a device load cabin so as to control the height of the whole system; the device load cabin is connected to the lower portion of the main air bag by tying a rope in a hanging mode, the lower portion of the device load cabin is connected with a supporting arm through a deviation control cable, and a measurement control module, a pneumatic sail face and a vector thruster are arranged on the supporting arm. The stressed direction of the pneumatic sail face is crossed with the action direction of the vector thruster in an orthogonality mode. The measurement control module receives the instructions sent by the device load cabin and controls starting and closing of the vector thruster and the rotation angle of the supporting arm.

Description

technical field [0001] The invention relates to a new type of aerostat, in particular to an aerostat system utilizing natural heat energy to float in the air, with adjustable height and controllable trajectory, which can be used as an important means for flight detection of adjacent space and planetary atmosphere. Background technique [0002] Near space (Near space) generally refers to the airspace at an altitude of 20-100 km from sea level, and is a space field that is rarely involved in current human activities. With the advancement of modern science and technology, the unique resource advantages of adjacent space have become the focus of attention of all countries. Stratospheric aerostats are an important means for the development and utilization of adjacent space resources. As a near space information platform, it can realize long-term real-time, all-weather and all-weather high-resolution earth observation and high-speed mobile communication in a specific area by carr...

Problems solved by technology

[0003] High-altitude balloons are currently the only mature stratospheric aerostats, but the commonly used zero-pressure balloons use the method of throwing sand and deflation to maintain altitude in order to cope with diurnal changes, and the high-altitude flight time is short (several days); Structural design issues, only dozens of days of flight in the Antarctic region; general hot air balloons consume a lot of fuel during the flight; the infrared hot air balloon (MIR) proposed by France has a long flight time (the average flight time is 3 weeks, the longest record 69 days), but can carry a smaller payload

More importantly, high-altitude balloons lack active control means and can only fly with the wind, unable to achieve cruise residence in a specific area

An ideal stratospheric airship can achieve fixed-point residence and cruising maneuvers at the height of the stratosphere, but the technology is difficult and the system is complex, and there is no successful application precedent.
