The invention provides a small unmanned airship using hydrogen and helium hybrid energy. The small unmanned airship comprises an air bag and a power device; the air bag is filled with hydrogen/helium mixed gas mixed according to a certain proportion to serve as floating gas of the airship; the power device comprises a hydrogen fuel battery pack and a motor which are connected with each other; the air bag is connected with the hydrogen fuel battery pack through a hydrogen and helium hybrid gas loop and is used for providing reaction hydrogen/helium mixed gas for a hydrogen fuel battery power system; and external air is connected with the hydrogen fuel battery pack through an air loop and is used for providing reaction oxygen for the hydrogen fuel battery power system. The hydrogen/helium mixed gas is used for replacing pure hydrogen to serve as fuel of the battery, potential safety hazards of the fuel battery in the operation process can be effectively avoided, and the service life of a fuel battery stack is prolonged. Meanwhile, due to the fact that the hydrogen is directly stored in the air bag, dependence on a storage medium steel cylinder is reduced, the dead weight of the airship is reduced, the load capacity of the airship is improved, and the purpose of miniaturization is achieved.
本发明提供一种使用氢氦混合能源的小型无人飞艇,包括气囊和动力装置;所述气囊中充有按一定比例混合的氢/氦混合气体作为飞艇的浮升气体;所述动力装置包括相互连接的氢燃料电池组和电动机;所述气囊通过氢氦混合气体回路与氢燃料电池组连接,用于向所述氢燃料电池动力系统提供反应氢/氦混合气体;外部空气通过空气回路与氢燃料电池组连接,用于向所述氢燃料电池动力系统提供反应氧气。本发明使用氢/氦混合气替代纯氢气作为电池的燃料,能够有效避免燃料电池在运行过程中的安全隐患,延长燃料电池堆的使用寿命。同时,由于氢气直接储存在气囊中,减少了对存储媒介钢瓶的依赖,从而降低了飞艇的自重,以提升其负载能力,达到小型化的目标。
