This invention relates to improvements in a turbine engine. More particularly, to rearrange the compressor and turbine in different ways to reduce the size of the engine to change the thermal impact on the nozzle and the turbine blades.
The evolution of the turbine engine has been utilized in aircraft to propel an airplane through the air with great speed and efficiency. Nearly all engines are constructed in a linear arrangement to use a single or two common shaft where airflow runs into a compressors that compresses an air and fuel mixture. The compressed mixture then is ignited and then expands through turbines where the hot exhaust gasses are expelled out of the turbine to provide propulsion. The elongated engine is extremely inefficient for size and further the high temperature of the exhaust requires expensive materials to resist damage from exposure of the heat. In old turbine engines, there is a front compressor (cold region) and a combustion chamber (hot region), and the turbines (hot regions). The front turbine and nozzles will be very hot and this can create a problem in a turbine engine and reduces the ability of the turbine to run at high temperatures with more efficiency.
In old turbine engines, there is a front compressor (cold region) and a combustion chamber (hot region), and the turbines (hot regions). The turbine and nozzles will be very hot, this can create a problem in a turbine engine. To increase the efficiency of the engine, the engine needs to run at higher temperatures. This is impossible, because of the temperature's impact on the nozzle and turbine blades. The disc engine has a unique design that allows the engine to run at higher temperatures.
Prior art compressors are limited from producing the pressure to run the engine at higher efficiency. The turbine engines become too large to accommodate bigger and faster aircrafts to the point where the turbine engines are an aerodynamic obstacle.
In other old technology turbine engines there is a limitation in the pressure of combustion needs to be equal or less than the pressure created by the compressor. This limits the power of thrust. In order to obtain more thrust, either the compressor needs to create more pressure or the size of the engine needs to be increased. As today's compressors are limited to the pressure produced, there is no way to increase the pressure with current compressor technology. All the turbine engines are consistently are being increased in size to accommodate bigger and faster aircraft to the point where the engines are so big that they become an aerodynamic and design obstruction.
Other limitations of the high temperature of the engine on the nozzle and turbine blade will be restricted to the increase of pressure in the system. The disc engine has a unique cooling system and good heat management.
Prior art turbine engines are engines Turbofan bypass jet engines where a turbo fan jet engine uses bypass flow that consists of the engine core (as described above) plus an added turbo fan blowing air through an added bypass cavity. In operation, the additional flow of air via the bypass cavity is mixed with the hot gases exiting the nozzle of the engine core thus boosting the thrust. Some design limitations of the turbofan bypass engine are the same as the jet engine previously identified plus the pressure of the bypass air jet is limited by the pressure produced by the fan.
Another prior art engine is a jet engine with an after-burner. Some military planes have jet engines with after-burners (fuel injector mounted into the bypass cavity). In operation gasoline is dispensed into the bypass cavity thereby increasing the temperature and the specific weight of the bypass flow to increase the thrust during emergency situations. This design has the limitations of the jet engine with after-burner are the same or similar to the jet engine above. The after-burners can be very efficient, and they also must be used sparingly during emergency situations. The additional mass that is added to the flow is used more efficiently if the speed of the gases exiting the nozzle could be increased because the thrust equals the mass of the gases multiplied by the speed of the gases. The pressure in the combustion chamber and the bypass ducts is limited to the pressure created by the fan and the compressor, thereby creating a limit to the speed of the exhaust gases.
