Inflatable water surface take-off and landing parafoil

Abstract

The invention discloses an inflatable water surface take-off and landing parafoil which comprises a parafoil body, an inflation and deflation device, a folding and unfolding device, a load cabin, a left parafoil rope and a right parafoil rope, wherein the left parafoil rope and the right parafoil rope are connected with the parafoil body and the load cabin. The load cabin has buoyancy and can float on the water surface, so that the parafoil can take off and land on the water surface. The parafoil comprises three or more transverse inflatable parafoil bags and longitudinal inflatable parafoil bags arranged at the two ends of the transverse inflatable parafoil bags and used for connecting the transverse inflatable parafoil bags into a whole. The inflatable parafoil bags are communicated with one another; the electric inflation / deflation pump inflates / deflates the parafoil through the inflatable parafoil umbilical cord; the two longitudinal ends of the interior of each longitudinal inflatable parafoil bag are each connected with a guide rope, the guide ropes are wound around a winding drum in a sealed cabin of a winder after being subjected to reversing traction of a guide device, and folding and unfolding of the parafoil are achieved through folding and unfolding of the winder on the guide ropes.

Description

technical field [0001] The invention relates to a parafoil, in particular to an inflatable water surface take-off and landing parafoil. Background technique [0002] Traditional marine environment monitoring and detection mostly use on-board monitoring and detection equipment as a parafoil that can make full use of the sea wind for a long time in the air. Compared with on-board monitoring and detection equipment, it can reduce the influence of the curvature of the earth, and the detection distance is longer, and the monitoring efficiency and scope are higher. Wider, more prominent advantages. Based on this, it is necessary to actively explore a parafoil capable of carrying marine environment monitoring and detection equipment. [0003] There are two ways to control the direction of the traditional ram parafoil: the first is to pull down one side of the trailing edge by the control rope; Wings collapsed. But both control methods have deficiencies: when adopting the first c...

Problems solved by technology

However, both control methods have disadvantages: when the first directional control method is adopted, some unfavorable situations will appear: for example, when one trailing edge is pulled, the lift of the wing surface increases, but the resistance increases faster

In addition, due to the existence of the reverse roll tendency, the control is not flexible enough, and it is easy to cause excessive control and enter the spiral stall motion

Although the second control method is relatively safe, the control force and control amount are relatively small when the method of closing the air inlet of the outer wing is used to control the direction of the large-area throwing parafoil.

And the existing parafoil cannot realize the function of automatic retraction, which has seriously affected the intelligence level of the parafoil

[0004] At the same time, the commonly used ram parafoil has an open air inlet, and the water inlet cannot take off, so it cannot take off on the water surface, which limits its scope of use.
