Abstract

The present invention is applicable to the field of airship technology, and provides a center-axis ventilated light-concentrating airship, which includes a hull, and a ventilation channel is provided through the center axis of the hull; the ventilation channel includes a first ventilation duct and a second ventilation duct ; The first air passage extends from the head of the airship to the middle of the hull, and the second air duct extends from the tail of the airship to the middle of the hull; and the first air duct is coaxial with the second air duct ; a transparent skin is provided on the upper part of the hull; a concentrator is arranged below the transparent skin area, and the concentrator is placed between the first ventilation duct and the second ventilation duct, so The symmetry plane of the light concentrator coincides with the symmetry plane of the transparent skin. The airflow in the central axis ventilation channel of the present invention can cool the photovoltaic cells therein, so that the photovoltaic cells will not reduce their service life and photoelectric conversion efficiency due to the influence of self-heating, so as to provide sufficient power source for the airship for a long time.

Description

technical field [0001] The invention relates to the technical field of airships, in particular to a center-axis ventilated light-concentrating airship. Background technique [0002] As a low-speed aircraft with long-lasting flight capability, high-altitude airship can stay in the upper atmosphere for a long time. It has broad application prospects in military and civilian fields such as earth observation, early warning and investigation, wide-area communication, and emergency relief. In recent years, it has also become the focus of domestic and foreign research. [0003] The development of a high-altitude airship involves a number of key technologies, including overall layout design, overpressure capsule design, energy system, flight control technology, and fixed-point landing. The lightweight structure of the airship's aerostat and the energy requirements for long-term wind-resistant flight make it necessary to take into account structural weight, power generation efficien...
