The invention discloses a double-layer balloon energy-saving safety type hot-air balloon aircraft which comprises an inner balloon, a hanging basket and a heater, the hanging basket is connected with the inner balloon through a hanging rope, an outer balloon is further arranged on the outer layer of the inner balloon, a sealed cavity is formed between the inner balloon and the outer balloon, and the heater is arranged in the sealed cavity. The inner balloon penetrates through the surface of the inner balloon and is provided with an air valve used for being communicated with the outer balloon, the heater is arranged at a heating opening formed below the inner balloon and the outer balloon, an airflow outlet is formed in the upper end of the inner balloon and the upper end of the outer balloon in a penetrating mode, and an exhaust valve umbrella used for blocking the airflow outlet is arranged in the inner balloon. The exhaust valve umbrella is in transmission connection with the control rope. Heat convection radiation and heat conductivity heat transfer coefficient of the balloon can be reduced, so that loss of heat convection radiation is reduced, heat in the balloon is insulated, and temperature difference between inside and outside can be kept for a longer time to realize stable flight in the air.
本发明公开了一种双层球囊节能安全型热气球飞行器,包括内球囊、吊篮、加热器,所述吊篮与内球囊通过吊绳相连接,所述内球囊外层还设有外球囊,所述内球囊与所述外球囊之间形成密封空腔,所述内球囊穿过其表面设有用于与所述外球囊连通的气阀,所述加热器设于所述内球囊和外球囊下方形成的加热口处,所述内球囊与外球囊上端贯穿设有气流出口,所述内球囊内部设有用于堵住所述气流出口的排气阀伞,所述排气阀伞与操纵绳传动连接。本发明能够减少球囊热对流辐射和热导率传热系数,从而减少热对流辐射的损失,使球囊内部热量保温能够更长时间保持内外温差而实现空中稳定飞行。
