Danfoss Motor – Hydrogen Oxygen Motor: How It Works
The hydrogen-oxygen motor uses the hydrogen and oxygen generated by the electrolyzed water to recombine the reaction. The principle is equivalent to the primary battery, and the generated electric energy drives the motor to rotate, thereby providing power.
Hydrogen-oxygen motor is one of the trends in the development of rocket motor technology in the world. Mastering the technology of hydrogen-oxygen motor is one of the symbols of a country becoming a space power. The development of large thrust hydrogen-oxygen motor is the development trend of liquid rocket motor technology at home and abroad.
Hydrogen-oxygen rocket motors are one of the most critical sub-systems for launch vehicles. “Aerospace development, power first” is the successful experience of the world’s major space powers. In the past two or three decades, the United States, the Soviet Union, Europe and Japan have successively developed J-2, SSME, RD-0120, Vulcain, LE-7. And the hydrogen-oxygen motor with the thrust of 100-300 kN, such as RS-68, is used in the core or upper stage of the launch vehicle, which greatly enhances the carrying capacity of the launch vehicle and effectively promotes the scale and scope of its aerospace activities. expand.
The principle of electrolyzed water: 2H2O=2H2+O2; in the most ideal case, the energy is not lost, and the same amount of electricity is produced to produce hydrogen and oxygen which can generate the same amount of energy, and the combustion produces so much. energy. However, the more the actual situation, the greater the loss of energy. The efficiency of electrolysis in the combustion of these two links is very worrying.
The Danfoss Motor states that the biggest advantage of the hydrogen-oxygen motor is that it is higher than the environmental protection. It may not be a heavy thrust, but the advantage of being higher is the critical parameter of the launch vehicle. Because the carrying capacity is directly related to the specific impulse, the relationship between carrying capacity and thrust is far less than the comparison. A higher load means that the launch vehicle can achieve a higher carrying capacity with a smaller weight. The launch vehicle itself is light in weight, the corresponding scale is small, and the ground logistics facilities are also small in scale. For a planet with water, the probability of surviving is greater. In the future, when the earth’s energy is depleted, it will be clean and cheap energy. No energy is available. Today, with high oil prices and increasing environmental pressures, all over the world are stepping up to find clean fuels that can replace gasoline.
