Description

DESCRIPTION

A ROTARY DISPENSING MECHANISM

The present invention relates to a rotary dispensing mechanism which allows launching of ammunition at different angles, which are used as a countermeasure against guided missiles.

Currently, at least two electronic warfare systems are provided in air vehicles, such as airplanes or helicopters, for protection from radar and heat guided missiles. A countermeasure dispensing system is used as the mentioned electronic warfare system, in which a cartridge with chaff or flare is located. The countermeasure dispensing systems are mounted on air vehicles. These dispensers are capable of dispensing in different directions by changing azimuth and elevation angles. Moreover, weight of these objects mounted on air vehicles is important because overall weight of the air vehicle is a critical parameter for flight performance. Within this context, the lower the overall weight, the lower the costs and the higher the flight performance/efficiency.

In the Turkey originated utility model document TR200708404, which is included in the known state of art, there is disclosed a countermeasure rotary dispenser within the scope of electronic warfare systems to protect the helicopter against guided missiles on a rotary wing flying platform. In this document, the fixing screw is protected along the azimuth axis. In said document, on the other hand, the elevation angle adjusting mechanism and the parts to which the mechanism is attached considerably increase the weight of the dispenser. This affects flight performance negatively and cannot solve the before mentioned problem.

Thanks to a rotary dispensing mechanism according to the present invention, a rotary dispensing mechanism which will provide a lighter rotary dispenser than existing systems is provided. With the invention, performance and efficiency are increased on the platform where the mechanism is used.
