A SHIELDING CASE FOR A ROTARY FLARE DISPENSING SYSTEM

The present invention relates to a heat shield system which protects flare systems located at an exhaust outlet of helicopters from hot exhaust gases.

In helicopters, gases with temperatures as high as 300°C exhausted from the exhaust during a flight reach a CMDS (Counter Measure Dispenser System) equipment, causing the equipment to exceed an operating temperature of 70°C and causing the equipment to not operate and be damaged. To solve this problem, a shield is needed to protect the equipment from the heat thereon. The heat shield design is made of a titanium material, which is one of the metal materials with the lowest heat permeability on the outer surface. In addition, an insulation material resistant to combustion and high temperature should be chosen and coated on an inner surface of the titanium heat shield.

The United States patent document US9932900B2, which is included in the known-state of the art, comprises a structure aiming to protect devices in an engine compartment of an air vehicle against high temperatures. The document discloses that geometry of the insulation cage structure is determined according to the geometry of the equipment to be thermally isolated.

The United States patent document US9134098B1 , which is included in the known-state of the art, relates to a cartridge launcher system used against rockets threatening an air vehicle. The invention discloses that cartridge launcher systems are positioned inside a protector, which is a launcher unit created to be armored and covered, in order to protect the air vehicle against attacks and bullets. It is disclosed that the covers on the protector aim to protect the cartridge launchers from external influences. It is disclosed that the protective equipment provided to protect launchers can be made of titanium, ceramic composite materials or any material with armor properties.

The United States patent application US20100326262, which is included in the known- state of the art, discloses a casing box which uses radar diversion reflectors with cartridge launcher systems. The invention discloses that the boxes serve as a protective plate and the direction of the shot can be changed by a pilot using a control mechanism located in the middle of the casing boxes.

Thanks to a heat shield system according to the present invention, cartridge launcher systems are enabled to be protected from heat and operate effectively.
