The invention relates to a parachute capable of easily controlling direction and speed. The parachute comprises a main canopy, an auxiliary canopy, a central rope, a direction control rope, a first-stage parachute rope, a second-stage parachute rope, a reinforcing belt and a roller skate, four exhaust holes are formed in the main canopy, the four auxiliary canopies are arranged above the exhaust holes respectively, the direction control ropes are arranged on the auxiliary canopies, and under the normal condition, the four exhaust holes are all in an open state; by pulling the direction control rope, the auxiliary canopy can cover the exhaust port, so that no airflow is exhausted in the direction, airflow is exhausted in the opposite direction, back-flushing airflow is formed, the parachute is pushed to move in the opposite direction, and the purpose of controllable direction is achieved. The air displacement in the target movement direction can be adjusted by controlling the two control parachute cords perpendicular to the target movement direction, so that the air flow of the opposite face in the movement direction is indirectly adjusted, and the effect of controlling the movement speed is achieved; the umbrella is convenient to operate, simple in structure, safe and reliable.

    本发明为一种容易控制方向和速度的降落伞,包括主伞衣、副伞衣、中心绳、方向控制绳、一级伞绳、二级伞绳、加强带、轮滑;主伞衣上开有四个排气孔,四个副伞衣分别设置在排气孔的上方,方向控制绳设置在副伞衣上,正常情况下,四个排气孔均处于开的状态;通过拉方向控制绳可以使副伞衣盖住排气口,使得该方向没有气流排出,而相对方向上有气流排出,形成反冲气流,推动降落伞向相反方向运动,从而达到方向可控的目的;可通过控制与目标运动方向相垂直的两根控制伞绳来调节该方向上的排气量,从而间接地调节运动方向相对面的气流量,达到控制运动速度的效果;该伞操作方便,结构简单,安全可靠。
