[0002] Turbo machines are machines with rotating blades that convert fluid movement into useful power. Today, there are power systems that enable many machines to operate. Power systems generally use petrol, diesel, fuel oil, natural gas, LPG, coal and nuclear fuels as fuel sources. These fuel types damage the environment. Therefore, a power system that utilises atmospheric air is of great importance.

The engine has an air inlet that collects air from the surrounding environment. The air is compressed in several compression stages with intercoolers between the compressors. The air is then purged of components with a relatively high liquefaction in a cleaner and then expanded in a turboexpander, which allows the air to be cooled close to air liquefaction temperatures. The air is then passed through a trimmer that removes nitrogen.

[0023] The invention relates to a turbo machine which is operated by the atmospheric air temperature and does not require any other fuel, and comprises the following parts: heat exchanger (1), which is located in the machine and provides cooling of the atmospheric air, compressor (2) connected to the heat exchanger (1), which compresses the cold air to a pressure of approx. 15 bar, gas turbine (4) connected to tube I (14) and enabling the air to perform work, a condenser (5) connected to the gas turbine (4) and condensing the refrigerant R134a in the condenser (5) via the air coming from the gas turbine (4), pump (6) connected to the condenser (5) and used to increase the pressure of the liquid coming out of the condenser (5), heater I (7) for heating the liquid coming out of the pump (6) to atmospheric temperature to obtain heated and pressurized gas, steam turbine (9), in which the heated and pressurized gas from heater I (7) in conjunction with heater I (7) is used to drive the steam turbine (9), electric motor (10) connected to the gas turbine (4) and used to compensate for the losses of the compressor (2) and the losses of the gas turbine (4), current frequency changer (11), which is connected to the electric motor (10) and prevents the compressor (2) from overheating, transmitter (12), which is connected to the current frequency changer (11) and enables the current value to be adjusted, alternator (13), which is connected to the steam turbine (9) and provides energy generation, ventilator (16) connected to the heater I (7) and heating the air.

[0024] The invention concerns a method of operation of a turbo machine which is fuelled by the temperature of atmospheric air and does not require any other fuel, and comprises the following steps: cooling of atmospheric air by heat exchanger (1), compression of the cooled air by the compressor (2) to a pressure of approx. 15 bar, the compressed and heated air is then transmitted to the gas turbine (4), transmission of air from the gas turbine (4) to the condenser (5), compression of the liquid coming out of the condenser (5) with the help of the pump (6), the liquid coming out of the pump (6) is heated to atmospheric temperature by the heater I (7) to obtain heated and pressurized gas, the heated and pressurized gas enters the steam turbine (9) and does work by expanding.

[0025] The subject of the invention is a turbo machine which operates with atmospheric air temperature. The machine consists of a gas turbine (4) and a steam turbine (9). Therefore, it is a two-cycle machine.

[0026] Gas turbine (4) cycle: The cold air cooled from the heat exchanger (1) enters the compressor (2). The cold air is compressed in the compressor (2) to a pressure of approx. 15 bar. The compressed and heated air enters the gas turbine (4). The gas turbine (4) ideally fulfils the work of the compressor (2). Unmet work losses are supplied by the steam turbine (9). The expanding air in the gas turbine (4) drops to about 80 kPa. The exhaust from the gas turbine (4) goes to the steam turbine (9) condenser (5) where the steam engine fluid R134a is condensed. Different suitable fluids can be used instead of R134a fluid The air coming out of the condenser (5) heats up a little and enters the heat exchanger (1) and is discharged from the exhaust. Thus, the gas turbine (4) cycle is completed. The outlet air of the gas turbine (4) condenses the fluid of the steam turbine (9). Thus, the fluid is condensed in the condenser (5) in the steam turbine (9) circuit. (Figure 1) To condense 1 kg of refrigerant; 1 kg * inlet enthalpy of refrigerant − outlet enthalpy of refrigerant = m kg

[0027] The formula giving the amount of air circulating in the gas turbine circuit corresponding to 1 kg R134a is given below. 1 kg R 134 a × h 10 − h 2 = m kg × h 5 − h 4

[0028] From the formula, the m information is obtained and the amount of air to be circulated in the gas turbine (4) circuit is found. Pressure and temperature values are found with the formula; T 3 T 2 = P 3 P 2 k − 1 k which is used in adiabatic compression and expansion where there is no difference in C p specific heats. Here k=1,4, P 2 atmospheric pressure is 1,01325 bar and P 3 pressure is decreased to approximately 80 kPa at the end.

[0029] Compressor (2) outlet pressure is the turbine inlet pressure. There is little change in C p in these pressure and temperature ranges. In the gas turbine (4) circuit, the gas turbine (4) ideally provides the work of the compressor (2). The electric motor (10) is switched on to provide the losses of the compressor (2) and the losses of the gas turbine (4). Therefore, the system operates in regime.

[0030] The electric motor (10) obtains its energy from the steam turbine (9). Tube I (14) is used for initial progress. When the system starts to operate regularly, tube I (14) is filled and valve (17) is closed. It is prepared for a 2nd stop.

[0031] The compressor (2) heats up too much when it reaches 15 bar or above. In order to prevent this heating, a current frequency changer (11) system enters the circuit. The outlet temperature of the compressor (2) is set to a certain state. In initial operation, the temperature transmitter (12) at the end of the compressor (2) switches the frequency and adjusts the current. The compressor (2) prevents the engine from being overstressed and overheating. It enters the regime state and then the steam turbine (9), heater I (7), condenser (5) and pump (6) are activated. The system operates at full load. The cold air coming out of the condenser (5) is slightly below the condensing temperature and goes to the heat exchanger (1). It heats up to ambient temperature in the heat exchanger (1). Thus, the gas turbine (4) circuit is completed.

[0032] Steam turbine (9) cycle: The liquid R134a from the condenser (5) is pumped to a pressure of 200 kPa by means of pump (6). The liquid coming out of the pump (6) is heated to atmospheric temperature by heater I (7). The heated and pressurised gas enters the steam turbine (9) and does work by expanding. The vapour coming out of the steam turbine (9) enters the condenser (5) again and thus the steam turbine (9) circuit is completed.

[0033] After the R134a refrigerant is condensed with cold air in the condenser (5), it is pumped to heater I (7) by means of pump (6), heater I (7) is heated to ambient temperature by means of a fan (16). This heating is achieved by forced convection heat transfer. The air speed blown by the fan (16) must be greater than or equal to 5 m / s. Otherwise, the water vapour in the air may condense on the heater I (7) pipes. For this reason, it must be dragged quickly over the pipe before condensation occurs. Tube II (15), like tube I (14), is used for initial progress. After the system has made progress, the valve (17) of tube I (14) and tube II (15) is closed. It prepares for a 2nd stop. (Figure 1) The cold air from the heat exchanger (1) is compressed by the compressor (2) until it reaches a pressure of about 15 bar and adiabatic state (Q=0). Since there is a hot air inlet at the first start-up, the current and frequency changer (11) will be activated. The engine gradually heats up with the temperature received from the temperature transmitter (12) at the output of the compressor (2). Air compressed to 15 bar pressure enters. The air taken from the outlet temperature of the compressor (2) heats the heater II (8) in the steam turbine (9) circuit by means of a heat exchanger (1). This process is applicable to a different embodiment of the invention for use in aircraft.

[0034] The main operation of the subject of the invention turbo machine is performed by the steam turbine (9). The steam turbine (9) rotates and drives the alternator (13). The alternator (13) generates electricity. It moves with electric motors fixed to the wheels, such as the recently fashionable electric cars. Or it drives a machine in the classical way. Whichever is suitable is decided in the project design.

[0035] In this system, the steam turbine (9) operates by expanding from ambient temperature to approximately -100°C. The outgoing R134a refrigerant enters the condenser (5). Thus, the circuit is completed.

[0036] Thermal efficiency is shown η thermal = 1 − T exhaust T input in Carnot cycle. η thermal = 1 − 273 , 15 − 100 273 , 15 + 40 → η thermal = 44.707 %

[0037] It is a theoretical efficiency. It is for a reversible state. If we compare it with otto and diesel, it is a very good result. It is also the work obtained without using any fuel. Under normal conditions, the efficiency of autto and diesel cycles is 35%.

[0038] In a different embodiment of the system according to the invention, where the system according to the invention is used in aircraft, a heater II (8) is added to the system, which is connected to the heater I (7) and heats the fluid. In this case, the steam turbine (9) connected to the heater I (7) is connected to the heater II (8) and enables the heated and pressurized gas coming from the heater II (8) to perform work. In addition, a compressor (2) connected to the heat exchanger (1) and a control system (19) that adjusts the current and frequency values by sensing the pressure are added to the system. (Figure 3)

[0039] Normally the clouds are high up. The pressure is lower than sea level pressure. Since the exhaust pressure is approximately 1 atmosphere, the exhaust air is distributed in the distributors. Due to the very cold coolant passing through the pipe, water particles are formed on the pipe surfaces in the honeycomb as atmospheric air passes through heater I (7) and heater II (8). At velocities above v = 5 m / s, these particles are dragged and discharged by the flowing air. So that the water particles do not freeze and lock the cooler core. Since it can make rain, hail and snow, the speed of the aircraft or helicopter should be decided by meteorologists. The ability to make it rain, which is one of the objects of the invention in question, provides a solution against drought in summer.

[0040] The aircrafts operate both on the ground and in the air. It lands at the first operate and at the end. In this case the exhaust varies between 22.625 kPa and 101.325 kPa. Therefore, the outlet pressure of the gas turbine (4) is taken as 22.625 kPa. It operates at this head for about 99% of the operating time. More work is taken from the gas turbine (4). In order to provide this system, the control system (19) is added to the compressor (2), which regulates the pressure and provides frequency current control.

[0041] In a different embodiment of the subject of the invention turbo machine, the air sucked from the atmosphere is compressed by means of a compressor (2). The outlet air is cooled by means of a fan (16) mounted under the helicopter or aeroplane and entrained upwards. If a pilot is used, the room is heated. Otherwise, it is directed up the sides of the airplane. Outside the distributor coil is fixed under the vehicle. The work of the compressor (2) is performed by turbine III (18). Insufficient energy is supplied by the energy taken from the airplane. The airplane or helicopter manoeuvres back and forth in front of the clouds to cool them. They make it rain, snow and hail. In the different embodiment of the subject of the invention turbo machine, the hot air blown from the bottom of the aircraft, for example, is blown hotter through the heater I (7). In this way, more work is done and energy loss is less. (Figure 5)

[0042] All battery-powered vehicles have to wait for 8 hours for recharging after charging and their life span is 2-3 years. In the turbo machine, the life span is estimated to be 25 years. It can also fulfil the three purposes described above at no additional cost.

[0043] The advantages obtained with the developed turbo machine are listed below. The machine zeroises the damage caused by fossil fuels to nature and living things. Since it operates with the temperature of the air in the atmosphere, there is no fuel tank and also fresh air is provided from the exhaust. The air is cooled by the heater and can prevent drought.

[0044] The turbo machine subject to the invention can be used as a drive engine in cars, minibuses, buses, vans, trucks and lorries on land. At sea; it can be used as a propulsion engine in ships and submarines.

[0045] There are about 8 parts in the inventive turbo machine. It is impossible to place all of these parts in the front of land vehicles. As in electric vehicles, it is placed at the front and bottom of the vehicle. Before this assembly work, a platform is built on the chassis. All devices are assembled on the platform. It is then covered with the body. The body is tilted sideways or forwards with the help of hinges. After the repair and maintenance process is finished, the body is brought to its place and tightened. This assembly and disassembly process is carried out with the help of forklift or crane.
