DESIGN OF A CROSS-FLOW DIGITALLY CONTROLLED GAS TURBINE ENGINE Russian patent published in 2022 - IPC F02C3/05 

FIELD: engines.

SUBSTANCE: apparatus comprises a cylindrical stator body with 4 rows of holes arranged along an axis and a turbine rotor with three blades of a "crescent" shape in profile, the inner side whereof is the working side, protected by a heat-resistant coating. The drive shaft of the rotor rotates on the bearings of the covers of the body. Two external linear multijet combustion chambers (CC) are attached to the stator: one top left, another bottom right, which determines the clockwise rotation of the rotor. The location of the CCs is determined by the horizontal chord line from the mid-semicircle of the working side of the vane positioned vertically. Fuel and air are supplied to the CCs in correct proportions. The rectangular gate shutters made to slide in the grooves of the guide bars located in the longitudinal recesses of the stator in front of the CC nozzle holes prevent the fuel-air mixture (FAM) from entering the stator. Holes of the exhaust system are located opposite the CCs. When the digital control and monitoring apparatus (DC), by contact-free sensors, determines that the working surface of the rotor blade is located in front of a CC filled with FAM, it issues a signal to the ignition apparatus creating an electric spark, the fuel-air mixture in the CC is ignited, the DC moves aside the shutter using an electric drive, thereby opening the nozzle holes, wherein the high-pressure burning gases exiting said holes form parallel gas jets with high kinetic energy acting on the rotor blades and thereby rotating the rotor. After combustion of the fuel, when the rotor is rotated to a certain degree, the exhaust system holes open, the shutter returns to the initial position, the DC issues signals to open the electromagnetic valves for the supply of compressed air and fuel to the CC, and thereby the work cycle of one of the CCs is formed; the second CC works in a similar manner. The exhaust gases rotate the turbine, wherein the shaft of said turbine is connected with the shaft of the AC generator. As the air compressor compresses air from the environment, it provides the CC with the required volume of oxygen; the compressor structure depends on the area of application of the engine. The compressor axle is rotated by an electric engine powered by an accumulator battery at start and by a generator during operation. If necessary, part of the compressed air may be used to cool the CC heaters.

EFFECT: gas turbine engines according to the proposed design can be applied in transport, power engineering and on agricultural machinery.
