The invention discloses a near space aerostat capable of reentry and return during long endurance. The aerostat is composed of a bag body and a reentry body. The bag body part comprises a main air bag, an auxiliary air bag, a rudder and an elevator. The rudder is arranged above the tail part of the main air bag and is used for adjusting the yawing direction of the aerostat; the elevator comprisesempennage pairs installed on the two sides of the tail of the main air bag respectively and used for adjusting the pitch angle of the aerostat. The main air bag is filled with helium, the auxiliary air bag is arranged in the main air bag and filled with air, and the auxiliary air bag is communicated with outside air through a hose and a valve. The auxiliary air bag is provided with an air blower and an exhaust valve and used for inflating and deflating. The multiple pairs of auxiliary air bags are distributed at different positions in the main air bag, and each pair of auxiliary air bags is symmetrically distributed along the axis of the main air bag. The reentry body part of the aerostat can be separated from a main body, the attitude is controlled by a flap rudder through acceleration ofa main engine, and hypersonic gliding reentry is adopted, so that the defects of a traditional launching mode are overcome, and the launching cost is reduced.

    本发明公开了一种长航时可再入返回的临近空间浮器,所述浮空器由囊体和再入体组成。囊体部分包括主气囊、副气囊、方向舵、升降舵。方向舵安装于主气囊尾部上方,用于调整浮空器的偏航方向;升降舵包括分别安装于主气囊尾部两侧的尾翼对,用于调整浮空器的俯仰角。主气囊中充有氦气,副气囊内置于主气囊中,内部充有空气,通过软管和阀门与外部空气连通;副气囊设置有鼓风机和排气阀,用于充气和放气。多对副气囊分布于主气囊中不同位置,每一对副气囊沿主气囊的轴线对称分布。该浮空器的再入体部分可以与主体分离,通过主发动机加速,由襟翼舵控制姿态,以高超声速滑翔式再入,克服传统发射方式的缺点,降低发射成本。
