On June 20th, according to CNBC reports, at the Kennedy Space Summit in Boston, Massachusetts on Wednesday, local time, Blue Origin founder Jeff Bezos revealed more about his moon plan Details, including explaining how to use lunar water ice to refine fuel for the lunar rover.
Bezos said at the time: "About the moon, we now know more things that we did not understand during the age of the Apollo moon landing. For example, after the Apollo moon landing plan, we knew that there were water ice deposits at the bottom of the moon crater. Collect these water ices, which are used to make hydrogen and oxygen, which are the main components of rocket propellants. "
Blue Origin is developing its lunar vehicle called "Blue Moon", and Bezos announced the prototype of this spacecraft last month. He said that "Blue Moon" is powered by a BE-7 engine that uses hydrogen and oxygen as fuel sources.
Bezos said: "The reason we chose this propellant is that we know that one day we will use propellants made of water ice on the surface of the moon to refuel the spacecraft on the surface of the moon."
The "Blue Moon" is large enough to carry several people and cargo to and from the lunar surface. Bezos has previously stated that the "Blue Moon" is consistent with NASA's plan to return astronauts to the moon by 2024.
Blue Origin ’s Latin slogan is “step by step, ferociouslyâ€. It has been studying multiple space systems at the same time. In addition to "Blue Moon", the company is also building a rocket called "New Shepard" for space tourism and a giant rocket called "New Glenn", which will be used for Launch satellites and other spacecraft.
Bezos invested more than $ 1 billion in Blue Origin Company each year by selling the shares he held on Amazon.
Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.
