Ballistic Helmets to protect people against bullets
Posted on October 29, 2009 - Filed Under Ballistic Helmet |
The main purpose of Ballistic Helmet is to protect people against high velocity ammunition, the impact of fragmentation header. Australian Defense Force (ADF) service recently introduced an integrated ballistic helmets. The shape of this bullet-proof helmet similar to the U.S. P ASGT helmets are based. In the design of these helmets are rarely given prominence on the wearer’s heat load. Amos Hare by Egglestone and laboratory tests showed that some soldiers experience “on the front of the head when wearing the Australian Defense Force ballistic helmet in a hot environment for hot spots.” As the bullet-proof helmet is a personal armor system, an integral part of wearing a bulletproof vest to wear when debris or disregard for environmental conditions, the helmet ventilation is to study for reducing the burden of its heat mechanism. Heat-resistant (IGAD) and the helmet laminated steam (Re) measurements used as the heat source sweating hotplate. These results suggest that to reduce the heat load of the most effective way is not ventilated laminates, but by including an air circulation provided by the gap between the plates and heat through ventilation. Sweating hot plate results into practice, by measuring the airflow at low speed into a dummy wearing a helmet airflow. These results indicate that those from the sweating, such as stoves heat load calculations, ventilation, unless there is a large number of helmets to delete the surface of how much the benefits of helmets. Is most likely that this will adversely affect the integrity of the helmet and reduce its ability to provide protection for ballistic missiles, its design. Members of intuitive feeling that the fund is established, ventilation, ventilation holes teenager to provide a substantial increase in comfort, the Asian Development Fund, bullet-proof helmet. This has been proved to be not very likely, because there is no heat from the exhaust a small amount of the benefits shown. A heat reduce the burden of a more appropriate way to teach a helmet is to encourage helmet under the big air and the national championship. As an installation in the head, in order to assist them in the airflow and more effective method of helmets would be more beneficial than the vent helmet.
