The invention discloses a ram parafoil and a flared landing method of the ram parafoil, and relates to the field of ram parafoils. The ram parafoil comprises a parafoil body, two trailing edge control ropes and two front edge pull-down ropes, the two trailing edge control ropes are connected with the two ends of the trailing edge of the parafoil body respectively, and the two front edge pull-down ropes are connected with the two ends of the front edge of the parafoil body through a plurality of upper airfoil parachute ropes respectively. When the front edge pull-down rope is pulled down, the upper wing surface parachute cords are driven to pull the front edge of the parafoil body to shield the air inlet, a plurality of pressure relief holes are formed in the two sides of the upper wing surface of the parafoil body respectively, the parafoil body is connected with shielding cloth used for sealing the pressure relief holes respectively, and each piece of shielding cloth is connected with one upper wing surface parachute cord through a connecting rope. When the front edge pull-down rope is pulled down, the upper airfoil parachute rope and the connecting rope are driven, so that the shielding cloth is separated from the parafoil body, and the corresponding pressure relief holes are opened. The ramjet parafoil and the ramjet parafoil flared landing method adopt auxiliary shielding of a front edge air inlet of a parafoil body and control of opening of an upper airfoil pressure relief hole to quickly change the aerodynamic configuration of the parafoil body to realize flared landing.
一种冲压翼伞及冲压翼伞雀降着陆方法,涉及冲压翼伞领域。冲压翼伞包括翼伞本体、两根后缘操纵绳及两根前缘下拉绳,两根后缘操纵绳分别与翼伞本体后缘两端连接,两根前缘下拉绳分别通过多根上翼面伞绳与翼伞本体前缘两端连接,前缘下拉绳下拉时带动上翼面伞绳拉动翼伞本体前缘遮蔽进气口,翼伞本体的上翼面两侧分别开设有多条泄压孔,翼伞本体分别连接有用于封闭各条泄压孔的遮蔽布,每块遮蔽布均通过连接绳与一根上翼面伞绳连接;前缘下拉绳下拉时带动上翼面伞绳和连接绳,使遮蔽布与翼伞本体分离并打开对应泄压孔。冲压翼伞及冲压翼伞雀降着陆方法采用辅助遮蔽翼伞本体前缘进气口和控制上翼面泄压孔打开来快速改变翼伞本体的气动外形实现雀降。
