Ottawa, Ontario, July 14, 2009 – Mawashi Protective Clothing Inc., from Saint-Jean-sur-Richelieu, Quebec, was awarded a contract by Public Works and Government Services Canada (PWGSC) to conduct a market study on cooling and heating systems for the dismounted soldier with a review of options.
As part of this mandate directed to Defence Research and Development Canada (DRDC) - Valcartier, Mawashi followed a project plan divided in three stages:
• Study of commercial and military off-the-shelf cooling and heating products and technologies.
• Strengths and weaknesses analysis of each product for an operational context, through an expertise in human factors engineering.
• Presentation of concepts and solutions to improve the thermoregulation of dismounted soldiers.
The dismounted soldier is often restricted in his operational framework and he is limited by his environment, his personal equipment, and the vehicles he uses (armored vehicles, ships, planes, etc.). In addition, motorized infantry troops may be at risk of hypothermia and hyperthermia in their work. The solutions offered by existing thermoregulation systems are often not ideal for the soldier (the products are too heavy, bulky, require demanding power sources, etc.).
Moreover, existing products do not solve the problem of regulation in "hot and cold" environments. There are two different types of equipment, independent for each environment and no product combines the two systems. The soldiers also face rapid changes in temperature and environmental conditions. The soldier can pass from the warmer to the colder and vice versa, eg in the desert, it is + 100 ° C during the day and - 1 ° C overnight. In an environment such as the Arctic, where the soldier is physically active the body temperature rises, then when he slows down, his perspiration is difficult to evacuate, creating a microenvironment with a poor thermal regulation, making him more at risk of hypothermia. Moreover, this exposes the soldier to the thermo-sensing devices which makes him more vulnerable and turns him into an easy prey.
In this project, Mawashi analyzed the advantages and disadvantages of existing products on the market, then presented the best options for the infantry soldier. Suggestions were made to develop an ideal and versatile concept, which could encompass the cooling and heating elements into one system, and solve the problems of thermal detection of infantry soldier.
