Rotax engine is produced in Austria, I know it already but the company who owned it is Canadian. Maybe because it is produced in Austria then the engine is still available for TB2 drone.
İt's true. Rotax currently a Canadian engine. But when we first flew Anka, we had a problem with another engine (Not Rotax) due to Austria. Thereupon, we immediately started to develop PD series motors first.
Today, when the Canadian embargo was imposed on both Rotax engines and Wescam EOTS systems, we started to use a lightened version of the PD series engines developed for Anka in TB2/3s. Also, Wescam EOTS was replaced with Aselsan CATS EOTS.
The new engine is heavier than the Rotax but more powerful. Therefore, the losses with increasing weight could be compensated by the increase in power.
CATS, on the other hand, is still not a Wescam, it's still a bit heavier. But Aselsan's new generation EOST systems are on their way. In that regard, there will be no performance difference between Wescam and CATS-2.
In fact, until a year or one and a half year ago, CATS was too bad to be used anywhere. It was heavy and especially bad at thermal imaging. When Canada, using the Karabakh war as an excuse, placed an embargo, President Tayyip Erdoğan asked about CATS. He was very angry with the response he got. Some heads were blown off in Aselsan!!
As a result of intense efforts, it was possible to approach Wescam EOTS standards, at least in thermal imaging. Even added a couple of features. For the weight, it turned out that a new design was needed despite all the lightening. For this reason, some people in Aselsan are working hard with some Far East companies on the new generation EOTS systems.
