Background

In the field of aerospace, both astronauts and pilots are required to experience an overweight environment. The great overweight acting on the human body can have adverse effects on the human body and pose a serious threat to the flight safety. Fighter plane pilots need to finish various maneuvering flights in air combat flight, the speed and the direction are constantly changed, and the acceleration in each direction is generated. With the continuous development of high-performance fighters, the modern fighter can easily realize 9-10G maneuver, and grey vision, tubular vision, blackout and consciousness loss caused by acceleration sometimes occur, thereby forming a serious threat to flight safety.

The acceleration counterguard suit is effective load-resisting equipment which is tested by practice. The protective clothing is a physical protective measure, and can prevent blood from flowing to lower limbs due to inertia force and hydrostatic pressure gradient during the overweight action period, improve blood supply of the head and improve the tolerance of the human body to overweight.

The existing acceleration confrontation protective clothing can be divided into an inflatable type and a liquid-filled type according to the type of fluid, the inflatable type is low in cost, and the existing acceleration confrontation protective clothing is the most important existing acceleration confrontation protective clothing. However, the inflatable protective clothing has the problems of large heat stress, long response time, low load resistance limit and difficult optimization of load resistance distribution.

The liquid bag of the existing liquid-filled protective clothing is made of a low-tensile-rate material, and the load-resistant stress loading is realized by adopting a static pressure opening and closing mode. However, the liquid bag of the liquid-filled protective clothing has a small initial flow area, and can realize a small deformation amount when being overweight and overloaded, so the liquid bag needs to adopt a complex distributed structure in order to realize a sufficient anti-load effect, and the liquid bag has poor air permeability and responsiveness in addition to high manufacturing cost.

When the acceleration confrontation protective clothing is overloaded, liquid in the liquid filling pipeline tends to flow in the direction opposite to the acceleration direction under the action of inertia force, the static pressure of the liquid in the liquid filling pipeline is increased due to the inertia force, and the static pressure is in direct proportion to the liquid density, the acceleration value and the depth according to a static pressure formula P which is rhogh, so that the instantaneous static pressure is in gradient distribution by taking the depth as a variable, for example, if the acceleration direction is a positive Z axis, the static pressure of a calf is greater than the static pressure of a thigh and the static pressure of an abdomen.

The liquid filling pipeline is made of a material with high elongation at break, and instantaneous static pressure is distributed in a gradient manner, so that expansion degrees of all parts of the liquid filling pipeline are different, and liquid flows in the liquid filling pipeline; at the same time, the liquid filling pipeline outwards props the clothes surface main body, so that expansion stress is jointly applied to limbs of a pilot by the liquid filling pipeline and the clothes surface main body. When the pilot is overloaded on the positive Z axis in a sitting position in the cabin, the expansion stress promotes the blood to flow back to the upper part of the body, so that the cerebral blood pressure can be kept normal under an overload state, and the endurance limit of the pilot on the overload on the positive Z axis is improved.

The liquid filling pipelines are relatively intensively arranged, so that on one hand, sewing or assembling is easier, and the integral manufacturing cost is lower; on the other hand, the free area of the garment surface main body which is not covered with the liquid filling pipeline is larger, so that the air permeability is better.

The liquid filling pipe sleeve is wrapped on the liquid filling pipe sleeve to play a role in protection, after the liquid filling pipe sleeve is expanded to be completely attached to the liquid filling pipe sleeve, the liquid forms a double-layer pipe wall structure, and the elongation at break of the liquid filling pipe sleeve is smaller, so that the expansion of the liquid filling pipe sleeve can be limited, and the load resistance stress is more balanced and more reasonable in distribution. In addition, because the lower extreme of left standpipe and right standpipe is higher than left trouser legs and right trouser legs respectively, so left standpipe and right standpipe are more difficult for butt to pilot's instep or other barriers under the prerequisite of guaranteeing to effectively exert pressure to the limbs to left standpipe and right standpipe are more difficult for taking place local buckling, and then have guaranteed the circulation of left standpipe and the inside liquid of right standpipe, have further promoted the anti-loading response speed.

the liquid filling pipe sleeve 40 is fixedly connected with the cloth surface main body 10; the liquid filling pipe sleeve 40 is wrapped on the periphery of the liquid filling pipeline 30 in a sleeved mode and extends along the liquid filling pipeline 30; the liquid filling pipe sleeve 40 and the liquid filling pipeline 30 are both made of materials with high elongation at break, and the elongation at break of the material of the liquid filling pipe sleeve 40 is lower than that of the material of the liquid filling pipeline 30; the circumference of the inner surface of the fluid-filled tube sleeve 40 is greater than the circumference of the outer surface of the fluid-filled tube 30 at the same cross-sectional position in the naturally extended state.

In this embodiment, the main body 10 supports other components of the acceleration resistant suit 100, and the main body 10 transmits stress when the liquid filling pipe 30 is expanded. The main body 10 is usually made of split materials by splicing and sewing, and the split mode is set according to different wearing modes and the position of a zipper for detachable opening and closing. The material of the main body 10 may be aramid fabric.

In addition to ensuring the designed elongation at break, the main body 10, the liquid-filling pipe 30 and the liquid-filling pipe sleeve 40 are required to satisfy a certain strength, such as a breaking strength. In the present invention, the standard for the determination of the breaking strength and elongation at break is GB/T3923.1-1997.

The material of the liquid filling pipeline 30 can be polyurethane rubberized fabric which has high strength, low gram weight and good comfort. The material of the liquid filling pipe sleeve 40 can be 507 brocade silk plain silk, which is referred to pages 447 to 450 of text of Chinese aviation materials handbook 7 coating, insulating materials and textile materials.

The abdominal sac 33 includes a left lateral sac 331 and a right lateral sac 332 which are independent from each other, the left lateral sac 331 is communicated with the left vertical tube 31, and the right lateral sac 332 is communicated with the right vertical tube 32, so that the left lateral sac 331 and the right lateral sac 332 can be opened along with the front chest opening zipper 21, thereby increasing the wearing convenience.

The liquid filled in the liquid filling pipe 30 may be pure water, and thus, may be used for drinking in an emergency. In order to apply sufficient body surface pressure to the limbs of the pilot when inflated, the overall filling volume of the filling line 30 may preferably be 3L to 4L, with the average radius of the filling line 30 being 24.7 mm; the cloth surface main body 10 is woven in a plain weave mode, the elongation at break in the weft direction ranges from 12.40% to 15.00%, and the elongation at break in the warp direction ranges from 8.03% to 15.00%; the elongation at break of the material of the liquid filling pipeline 30 is more than or equal to 38 percent, the elongation at break of the material of the liquid filling pipe sleeve 40 is less than or equal to 25 percent, and the latitudinal direction of the garment surface main body 10 is perpendicular to the axial direction of the left vertical pipe 31 or the right vertical pipe 32. Further, the garment surface main body 10 is formed by blending and weaving Kevlar fibers and Nomex fibers. In the main body 10, the proportion of Kevlar fibers is 75% and the proportion of Nomex fibers is 25%.

When the acceleration-resisting protective clothing 100 of the present invention is overloaded, the liquid in the liquid-filling pipeline 30 tends to flow in the direction opposite to the acceleration direction under the action of the inertia force, which causes the static pressure of the liquid in the liquid-filling pipeline 30 to increase, and the static pressure is proportional to the liquid density, the acceleration value and the depth according to the static pressure formula P ═ ρ gh, so the instantaneous static pressure is distributed in a gradient with the depth as a variable, for example, if the acceleration direction is a positive Z axis, the static pressure of the lower leg is greater than the static pressure of the upper leg is greater than the static pressure of the abdomen.

The liquid filling pipeline 30 is made of a material with high elongation at break, and because the instantaneous static pressure is distributed in a gradient manner, the expansion degrees of all parts of the liquid filling pipeline 30 are different, and liquid flows in the liquid filling pipeline 30; at the same time, the liquid filling line 30 outwardly expands the main body 10, so that an expansion stress is applied to the limbs of the pilot by the liquid filling line 30 and the main body 10. When the pilot is overloaded on the positive Z axis in a sitting position in the cabin, the expansion stress promotes the blood to flow back to the upper part of the body, so that the cerebral blood pressure can be kept normal under an overload state, and the endurance limit of the pilot on the overload on the positive Z axis is improved.

The liquid filling pipelines 30 of the invention are relatively intensively arranged, so that on one hand, sewing or assembling is easier, and the whole manufacturing cost is lower; on the other hand, the clothing surface main body 10 has a larger vacant area not to cover the liquid filling pipe 30, and therefore, has better air permeability.

The liquid filling pipeline 30 of the invention is divided into the left vertical pipe 31 and the right vertical pipe 32 which extend from the upper part to the lower part of the garment panel main body 10, liquid is relatively concentrated and expands depending on elastic deformation, the shape of the cross section of the pipeline is approximate to a circle after the liquid is filled, thus the initial flow area is large, and in addition, the liquid in the left transverse bag 331 and the liquid in the right transverse bag 332 can respectively supplement the liquid in the left vertical pipe 31 and the liquid in the right vertical pipe 32, so the anti-load response is quicker when the garment panel main body is overloaded. The liquid filling pipe sleeve 40 is wrapped on the liquid filling pipe sleeve 30 to play a role in protection, and after the liquid filling pipe sleeve 30 is expanded to be completely attached to the liquid filling pipe sleeve 40, due to the fact that a double-layer pipe wall structure is formed on liquid and the elongation at break of the liquid filling pipe sleeve 40 is smaller, expansion of the liquid filling pipe sleeve 30 can be limited, and the load resistance stress is more balanced and more reasonable in distribution. In addition, since the lower ends of the left vertical tube 31 and the right vertical tube 32 are higher than the left trouser leg 12 and the right trouser leg 13, respectively, it is preferable that the distance from the lower end of the left vertical tube 31 to the lower end of the left trouser leg 12 and the distance from the lower end of the right vertical tube 32 to the lower end of the right trouser leg 13 are both greater than 150 mm.
