According to the inflation and deflation type flying parafoil capable of stretching out and drawing back automatically, the inflation and deflation type air bag is additionally arranged on the basis of the parafoil, so that it is guaranteed that the aerodynamic shape of the parafoil can still be kept under the conditions of crosswind or wind catching or no wind, and under the condition of strong wind, the wind action area of the parafoil can be reduced by contracting the parafoil, so that the air inflation and deflation type flying parafoil is more stable. Therefore, resistance formed by wind power is reduced. Comprising a load cabin, a traction rope connected with the load cabin and a parafoil body connected with the load cabin through a plurality of parafoil ropes. The device further comprises an automatic telescopic mechanism. The parafoil body comprises a canopy and a plurality of inflation and deflation type air bags. The air bag is connected with the canopy; the automatic telescopic mechanism is used for driving the two longitudinal ends of the parafoil body to stretch out and draw back so as to adjust the wingspan area.

    本发明提供一种可自动伸缩的充放气式飞行翼伞,在翼伞的基础上增加了充放气式气囊,由此来确保翼伞在侧风或兜风或无风等情况下仍能保持气动外形,而且在遇到大风条件下,能够通过收缩翼伞,减少翼伞风力作用面积,从而减少风力形成的阻力。包括:载荷舱、与载荷舱相连的牵引绳、通过多根翼伞绳与载荷舱相连的翼伞本体;还包括自动伸缩机构;所述翼伞本体包括伞衣和多个充放气式气囊;所述气囊与所述伞衣相连;所述自动伸缩机构用于带动翼伞本体纵向两端的伸缩,以进行翼展面积的调节。
