OTTAWA — No, they are not testing the latest in military food rations.The Canadian Forces are using a giant oven in Ottawa to replicate summer conditions in Kandahar, and there is nothing culinary about their goal. Instead, they want to see how their 43-ton Leopard tanks will react under the Afghan sun.
It seems we now have some information on the effects an Afghan summer day will have on the Leo C1 & its crew, and we know ways to reduce this effect. Hopefully we can put this knowledge to use quickly & make this a non-issue.
One of the biggest concerns is solar loading on the tank. Basily, the conversion of sunlight on the outside to heat on the inside. As most people know, a black car parked in the sun will get hotter than a white car. So, it seems odd to me that the tests did not look at painting the tanks a lighter colour (like an arid tan) and determining the benefits achieved. If it works, the concept could be extended to all vehicles (as time, recources, and the BG's tempo allows). Sure, other veh may have AC, but that requires the vehicle to be running (and so consumes fuel).
As a single measure, paint will not meet the need. However, it could help when used in conjuction with other options.
