Abstract

The invention is suitable for the technical field of airships, and provides a center axis ventilation and light condensation airship which comprises an airship body, and a ventilation channel is arranged on the center axis of the airship body in a penetrating mode; the ventilation channel comprises a first ventilation pipeline and a second ventilation pipeline; the first ventilation channel extends from the head of the airship to the middle of the airship body, and the second ventilation channel extends from the tail of the airship to the middle of the airship body; the first ventilation pipeline and the second ventilation pipeline are coaxial; a transparent skin is arranged at the upper part of the airship body; a light condenser is arranged below the transparent skin area, the light condenser is arranged between the first ventilation pipeline and the second ventilation pipeline, and the symmetry plane of the light condenser coincides with the symmetry plane of the transparent skin. Airflow in the center axis ventilation channel can cool the photovoltaic cell in the center axis ventilation channel, so that the situation that the service life and the photoelectric conversion efficiency of the photovoltaic cell are reduced due to the influence of self heating and the like is avoided, and therefore a sufficient power source can be provided 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...
