The invention discloses a method for improving the gliding ratio of a ram parafoil, belongs to the technical field of ram parafoils, and improves the gliding performance of the ram parafoil by changing the canopy structure shape of the ram parafoil through a mechanical mechanism method. By adopting the shape memory alloy, after the ram air inlet canopy of the parafoil is unfolded, the shape memory alloy wire is heated through the resistance wire, so that the shape memory alloy wire supports the covering cloth at the front edge notch and recovers to a shape capable of isolating ram air inlet, and the front edge air inlet is in a closed state; the adverse effect on the gliding performance of the parafoil caused by air inflow of the front edge of the parafoil can be avoided, and the aerodynamic performance of the parafoil is improved.

    本发明公开了一种提升冲压翼伞滑翔比的方法,属于冲压翼伞技术领域,通过机理性方法改变冲压翼伞的伞衣结构外形提高了其滑翔性能;本发明采用形状记忆合金,在翼伞冲压进气伞衣展开后,通过电阻丝加热,使形状记忆合金丝撑起前缘切口处的盖布,恢复成能够隔断冲压空气进气的形状,让前缘进气口处于关闭状态,能够解决冲压翼伞前缘进气对翼伞滑翔性能的不利影响,提高冲压翼伞的气动性能。
