Problems solved by technology
The airdrop dummies currently used are generally of iron structure, and their surface hardness is far from the characteristics of human skin, and the overall setting of the dummy skeleton is also very different from the physical characteristics of the human body, resulting in differences between the airdrop test results and the actual situation. Big error, can't really reflect the physical characteristics of the pilot's parachute opening in reality

Embodiment Construction
[0023] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention. Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The subsequent description of the specification is a preferred implementation mode for implementing the present invention, but the description is for the purpose of illustrating the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.

The invention discloses an airdrop dummy, which comprises: a skin unit, a trunk skeleton unit, a hip bone unit, a counterweight unit and a hook for hanging, wherein the trunk skeleton unit is fixedly connected to the hip bone unit by bolts, and the hanging The elastic hook is installed on the side end of the trunk skeleton, and the counterweight unit includes a leg counterweight box which is arranged at the lower part of the hip bone unit and is fixedly connected to the hip bone unit, and a shoulder box which is arranged close to the trunk skeleton unit. The arm counterweight box at the joint is used to adjust the weight and center of gravity of the dummy, and the skin unit is made of soft material, and wraps the torso frame unit, hip bone unit and counterweight unit located inside it. An airdrop dummy provided by the present invention has the same physical characteristics as the surface of human skin, and its design weight and center of gravity can be adjusted. It is suitable for different types of lifesaving parachute opening experiments, and can accurately reflect the reality The parachute opening characteristics, thereby improving the results of airdrop experiments.
Description
technical field [0001] The invention relates to a device for testing a lifesaving parachute, in particular to an airdrop dummy. Background technique [0002] The life-saving parachute is one of the key equipment of the ejection life-saving system, and the dynamic load of the parachute opening must meet the physiological tolerance of the human body. At present, the research on the dynamic load of parachute opening is mainly focused on the theoretical modeling and calculation of the parachute opening stage. In order to test the physical characteristics of the pilot parachute opening, it is necessary to develop a test dummy, wear the parachute on the body, and carry out the test through the aircraft. Airdrop test. The airdrop dummies currently used are generally of iron structure, and their surface hardness is far from the characteristics of human skin, and the overall setting of the dummy skeleton is also very different from the physical characteristics of the human body, res...
