Air-drop dummy

Abstract

The invention discloses an air-drop dummy; the air-drop dummy comprises a skin unit, a body framework unit, a hip bone unit, a counterweight unit and a hook, wherein the body framework unit is fixedly connected with the hip bone unit by bolts, the hook is installed on a lateral end of the body framework; the counterweight unit comprises leg counterweight boxes which are arranged at the lower portion of the hip bone unit and fixedly connected with the hip bone unit, as well as arm counterweight boxes which are arranged close to shoulder joints of the body framework, so as to adjust the weight and gravity center of the dummy; the skin unit is made of a soft material; and the skin unit wraps the body framework unit, the hip bone unit and the counterweight unit therein. The provided air-drop dummy has the same physical characteristics as the surface of human skin; the designed weight and gravity center thereof can be adjusted; the air-drop dummy is applicable to parachute-opening experiments of different types of escape parachutes; the parachute-opening characteristics of the escape parachutes in real conditions can be accurately reflected, thus improving the results of air-drop 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...

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
