Eaton Char-Lynn Motor – Application Development Of Ramjet
The Eaton Char-lynn Motor stated that the ramjet is a new type of cutting-edge aerospace science technology for high-speed flight. It is developing rapidly with each passing day. In this field, there are a wide range of complex issues that need to be addressed.
As the flight speed increases, it is required to design and manufacture more efficient components – diffusers, combustion chambers, and tail nozzles. Some countries are planning to increase the speed of ramjet engines to 5-7 times the speed of sound, or even higher (about 5300-7400 km / h). This requires solving a series of new problems. For example, it is first required to solve the thermal barrier problem. When M=5 is flying, the temperature of the engine wall surface after rubbing against the air can reach about 1000 °C. After the combustion chamber is heated, the temperature will reach about 2500-2800 °C, which requires a material with higher temperature resistance. Secondly, in order to warm the combustion chamber to a higher temperature, the currently used fuel (kerosene) is not acceptable, which requires high-energy fuel.
Today has entered the era of atomic energy. Therefore, the use of atomic energy in ramjet engines has attracted many scientists to make unremitting research. This ideal will become a reality in the near future.
In the upper layer of the Earth’s atmosphere, part of the air is decomposed into ions due to the action of the sun and cosmic rays. When these ions recombine into molecules, a large amount of energy is released, so it is possible to inject a small amount of catalyst into the engine to make ions. Combine the ingredients and release the energy to propel the aircraft so that there is no need to carry fuel at all. The voyage of this ion ramjet engine can be considered unlimited.
