A brief history of the dummy model used in the crash test:

In 1948, the U.S. Air Force used a human model for the first time to do an aircraft seat ejection test;

3.5% mannequin: represents a short stature with a height of 148 cm and a weight of 56 kg.

At the NACP European Safety Crash Test Center, Hy-drid3 is used to collect frontal crash information. Child mannequins:

1.6 month mannequin: height 67 cm, weight 10 kg;

2. December mannequin: height 76 cm, weight 13 kg;

3.18 month mannequin: height 83 cm, weight 16 kg;
