The soldiers who while serving their nation face harsh climatic conditions can now have a sigh of relief. The US army’s latest invention, which is a protective helmet with a built-in-air conditioning system, will let the soldiers fight the heat in the battle field without any hassles.
The new technology helmet, which is still at a developing stage, will give relief to the soldiers from the scorching heat through a powered air purifying respirator.
The respirator has a hose which is connected to the face mask from a blower unit and battery pack which hangs off the hip or back.
The concept for the forthcoming generation of chemical, biological, radioactive, and nuclear respirators began developing in the year 2013 by the scientists at the Edgewood Chemical
Biological Center which is a part of the US Army Research, Development and Engineering Command.
The researchers developed a fan which was embedded within the mask’s filtration system that does not use much power. It was also light in weight and less bulky in comparison with other standard respirators.
Apart from being light weight and powerful, this latest system will take the comfort and effectiveness of the mask to the next level.
The helmet functions by pulling air through a filtration system which is located on the side of the mask and sweeps it across the nose cup to allow for even flow across the face.
The mini blower also prevents any contaminates from outside to enter the mask. When a user exhales the air valve closes and diverts all the clean air into the mask’s eye cavity to over-pressurize the face piece.
In the studies conducted to test the mask, it was concluded that the commercial version of the M50 joint service general purpose mask is more comfortable for a soldier. The mask remains equally effective while crawling, running, or during the rifle exercises, and also at the time when a soldier is learning the fighting skills.
The real-time data on mask protection factors, thermal sensation, and comfort to the soldier were shown during the technology demonstrations.
The researchers are foreseeing a mask which will sense the need of a fan to come on and off based on physiological observations and the ability of the user to take over the control of operational mode of the system.
