LEOPARD 1A5NO2
“RUBBER BULGES/DEFLECTORS”

INTRODUCTION
I found some more footage of the modification in use on the tanks, and i have made a bug report for it wich has since has been aknowlegded, also a report regarding the name of the tank. I tought it might be interesting to see more of the bulge ;) so here is some information and footage of it. so this post will be about the bulges!

HISTORY
This is a Norwegian invention and was developed in the late 1980s at the The Norwegian Defense Research Institute (FFI- Forsvarets forskningsinstitutt)

This was developed for all Leopard 1 hulls, and was fitted to the Leopard 1A5NO, the Leopard 1A5NO2 (in-game verison) and the Leopard 1A1NO. and all the other Norwegian Leopard 1 Hulls wich was in use at that time such as brigdelayers and recovery vehicles

Leopard 1 has a very visible thermal signature, extra due to the rectangular exhaust grates, and this bulge was developed to reduce the thermal signature, They were mounted above the outlet of the exhaust on both sides of the engine, in the way that they were leading the hot exhaust away from the Eigne and hull

(you can also see the exahust fumes being lead away by it!)

These infared pictures show’s how it worked, and that it worked!

The Norwegian Defense Research Institute has done a lot of stuff trough the years, with many clever ideas, like the Spermal firebombs or the terne rockets, then many smaller inventions like these rubber wings/bulges ;)

A couple vehicles as well, but not directly linked to the Defense Research Institute tough hehe

Also, some model-kits has been inspired by this and gone into detail with these bulges

The grooves/lines that we can see on the top of the bulges/wings are most likely for the soldiers to step and stand on it without slipping!!!

Here we just can see that the rubber bulge has been covered with a white stuff or something as camouflage, that could be a thing on the camouflages

On second thought, exhaust deflectors is probably a better name for this haha, but it has been called many names, mostly “rubber bulges”

Rubber bulges, rubber wings, batman wings, exhaust deflectors, to name a few names and nicknames it got trough the time

Great news, this both verifies the “rubber bulges”, exhaust deflectors were used on the Leopard 1A1NO as well as its a close up picture of them. Tought it might be interesting to see
