Employees of the Zhukovsky and Gagarin Air Force Academy have patented a flame tube for a combustion chamber. The device allows for more precise control of air supply to the combustion zone, which increases fuel combustion completeness and reduces emissions.
The design consists of a tubular body with three annular belts of slots. Air necessary for combustion enters through them. Each slot is equipped with a flow regulator — a movable damper with an aerodynamic profile. The dampers can rotate, opening or closing the slots depending on the engine's operating mode.
Thanks to this, air is distributed optimally in all modes — from low throttle to take-off power. Fuel burns more completely, and the engine runs more efficiently. The patent may find application in aviation and stationary gas turbine installations.
