Welcome to Savunma Türkiye youtube channel.
In this video, we will focus on ASEL FLIR systems, which are FLIR systems developed by Aselsan for fixed-wing and rotary-wing, Manned and Unmanned Aerial Vehicles.
Our video will mainly be about air vehicles, but we will also provide brief information about the use of ASEL FLIR systems on land and sea vehicles. However, since we have reviewed ASEL POD systems in our videos before, we will not mention them again here.
FLIR is an abbreviation consisting of the initials of the words Forward Looking Infra Red. It is defined as a modern electro-optical reconnaissance, surveillance and targeting system consisting of sensors sensitive to radiation corresponding to the infrared range in the electromagnetic spectrum and used especially for military purposes.
What is generally meant by the term FLIR system is the systems resembling a round ball, which are mostly located under the fuselage or in the nose of the aerial vehicle. These ball like structure, called gimbal, which can rotate in all directions, contain many systems placed according to design needs, such as thermal cameras, day cameras, laser range finders, laser target markers, laser pointers, laser point tracker sensors etc.
FLIR, that is, electro-optical reconnaissance, surveillance and targeting systems integrated into air platforms, helps greatly to perform different tasks of the platforms such as reconnaissance, surveillance, target marking, target illumination and target designating.
It is important for FLIR systems to be lightweight, as they are installed on aerial platforms. For example, if an aircraft with a maximum payload of 300 kilograms carries a FLIR system weighing 150 kilograms, only 150 kilograms can be allocated for the remaining systems or ammunition.
When the same vehicle carries a 50-kilogram FLIR system, 250 kilograms can be allocated for the remaining systems or ammunition. This offset makes the aircraft more effective.
An aircraft is exposed to great vibration due to weather events as well as the effect created by its own powerplant. That’s why FLIR systems are expected to first overcome these physical drawbacks, minimize the existing vibration and shock effects, and then provide high performance by obtaining a clear image.
In parallel with the Turkish Defense Industry’s development and production of Manned and Unmanned Aerial Vehicles, there emerged a requirement for FLIR systems to be integrated on these platforms.
The first project where the requirement was defined was the Cougar Helicopters Joint Production Program in 1996. Within the scope of the program, the need for the FLIR system in helicopters was supplied with the ASEL FLIR 200 system, developed and produced under the responsibility of Aselsan.
Aselsan cooperated with the US company Raytheon within the scope of the project. The ASEL FLIR 200 project, as it was the first project of the company, was an important milestone in the development of Aselsan’s FLIR systems.
The ASEL FLIR 200 system was later integrated into the Turkish Coast Guard’s SAR helicopters. In addition, the naval version of the system, the ASEL FLIR 200D System, was chosen for the Tuzla class Patrol Boats of the Turkish Navy.
Within the scope of the T129 Attack and Tactical Reconnaissance Helicopter project, a newer version of ASEL FLIR 200 system was needed. For the T129 helicopter project, Aselsan has developed the ASEL FLIR 300T system, this time without external support.

See you in the next video, goodbye.
