Not long ago, NASA announced a very avant-garde and technologically advanced propulsion system for future space vehicles. The system is led by NASA's subsidiary, the Marshall Space Center, and is fully known as the Heliopause Electrostatic Rapid Transit System, also known as the Solar Electric Sail Propulsion System HERTS. Is it particularly futuristic to look at the appearance alone? Has it overturned your understanding of aircraft? Structural composition of electronic sails The electronic sail is not as complete as the traditional sail surface, and as the main part of the propulsion system, there are some particularly slender aluminum wires. Yes, you're not mistaken. Those slender wires are aluminum wires. Of course, this is not a common aluminum wire in our daily lives. These aluminum wires are extremely thin and long, with a diameter of 1 millimeter, roughly the same thickness as a paper clip, and they are super long, measuring 12.5 miles, or about 20 kilometers. What is the concept of this length? It is almost the length of 219 football fields arranged together. An electronic sail typically consists of 10-20 aluminum wires radiating from the center to the surroundings. After the rocket reaches the designated position, the aluminum wire is extended from the center to both ends, and two small rockets are used to propel and complete the fan-shaped deployment task of the aluminum wire group. Complete the final deployment form of the electronic sail. The Power Source of Electronic Sails Of course, having such an electronic sail propulsion system is not enough to set sail in space. The important aspect of interstellar navigation is propulsion power. Traditional aerospace engines require their own propellants, which account for a large proportion of the total mass of rockets and seriously constrain the payload and flight distance of spacecraft. Therefore, seeking more effective ways to advance has always been the direction of scientific research. Scientists have turned their attention to the sun, the ultimate energy boss in the solar system. Electronic sails are propelled by the solar wind generated by the sun. Unlike the wind composed of molecules on Earth, solar wind is a stream of supersonic plasma charged particles emitted from the upper atmosphere of the sun, composed of particles such as protons and electrons, and the effects they produce when flowing are very similar to air flow. The density of the solar wind is very thin and insignificant. Generally, in the interplanetary space near Earth, there are several to dozens of particles per cubic centimeter, while the density of the wind on Earth is 268.7 billion molecules per cubic centimeter. However, the strong force of the solar wind is far stronger than the wind on Earth. The speed of the solar wind near the Earth is generally 350-450 kilometers per second, and can reach 800 kilometers per second when strong. It may not feel much just looking at the numbers. You should know that the strongest...

Main Defects and Causes of Aluminum Alloy Extrusion Materials Defects usually refer to areas that do not meet the ordering standards or conditions, which either affect the appearance or use of the product. They are avoidable in production and are a direct reflection of product quality. Acceptable defects that only affect the appearance of the product and can be eliminated through subsequent finishing or processing without affecting its use, such as surface contamination, scratches and scratches that are not out of tolerance, pits, bending, twisting, flat gaps, peeling, bubbles, extrusion cracks, dimensions, etc. These defects are usually caused during extrusion and subsequent finishing, packaging, and transportation processes. Unacceptable defects that cannot be eliminated through subsequent finishing or processing, such as coarse crystal rings, layering, shrinkage, poor welding, unqualified flaw detection, excessive oxide film, metal and non-metallic slag, heat treatment cracks, over burning or overheating, as well as excessive scratches and scratches, bending, twisting, flat gaps, peeling, extrusion cracks, dimensions, etc. Some of these defects are inherited from metallurgical quality, such as unqualified inspection, excessive oxide film, metal and non-metallic slag, etc., and some are caused by process and mold reasons in extrusion production. Surface pollution, scratches, and bumps - weak quality awareness during production and lack of protection for product surfaces; Or there is an issue with the packaging method, which may cause collision or rubbing during rotation and transportation. Scratches - the mold work area is not cleaned thoroughly; The working track of the press or saw machine is not cleaned thoroughly. Pitted surface - insufficient hardness of the mold working zone; The extrusion temperature is too high; The squeezing speed is too fast. Bending, twisting, flat clearance - mold design issues; Unreasonable extrusion temperature or extrusion speed; The quenching medium temperature is too low; Insufficient stretching or other finishing methods. Peeling and bubbles - loose ingots; The size of the extrusion pad is unreasonable; Oil stains on the surface of the ingot or extrusion cylinder; Squeeze temperature or speed too fast. Squeeze cracks - the extrusion temperature or speed is too fast. Size - Unreasonable mold design; The extrusion speed control is inconsistent before and after. Coarse crystal ring - improper control of alloy composition; Unreasonable extrusion process design; The heat treatment temperature is too high and the insulation time is too long. Layer forming - surface defects on the ingot not cleaned by turning; Oil stains on the surface of the ingot or extrusion cylinder; Unreasonable mold design. Shrinking tail - the squeezing speed is too fast; The temperature difference between the extrusion cylinder and the ingot is large; Less residual extrusion or less removal of the end of the product; There is oil stains on th...

Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring (coloring mainly includes oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, etc.). Aluminum materials are extremely unstable in the air and can easily form oxide films that are difficult to recognize with the naked eye. Due to the different processing methods for aluminum parts, such as casting, direct cutting from extruded sheets, mechanical precision processing, or heat treatment or welding after different processes, the surface of the workpiece will present different states and varying degrees of dirt or marks. Therefore, in the pre-treatment process, the pre-treatment process must be selected based on the actual situation of the workpiece surface. In the pre-treatment process, it should be noted that although the natural oxide film on the surface of fine machined parts is only initially formed, there is an excessively thick oxide layer formed during the casting process on the surface that has not been machined, and a layer of oily and sintered coke is formed before the workpiece is transferred to the heat treatment or welding process. The treatment precautions for these situations are as follows: (1) Attention should be paid to the pre-treatment process of precision machined parts: Although the natural oxide film on the surface of the precision machined parts is only initially formed and easy to remove, it is heavy and greasy, especially in and around the eyelets (added due to lubrication needs during machining). These types of workpieces must be cleaned with organic solvents first. If directly washed with alkali, not only is the oil heavy and difficult to remove, but the precision machined surface cannot withstand long-term strong alkali corrosion, The result will also affect the roughness and tolerance fit of the workpiece surface, which may eventually become a waste product. (2) The issues that need to be noted in the pre-treatment process of casting molded parts. Not all surfaces of cast parts have undergone mechanical processing. Unmachined surfaces have an excessively thick oxide layer formed during the casting process, and some even contain sand layers. At this time, the original oxide film in this area should be removed first using machining or sandblasting methods, or processed after alkali washing. Only in this way can the original oxide layer in the unprocessed area be removed and the tolerance dimensions of the machined area be avoided from changing. (3) During the pre-treatment process of workpieces that have undergone heat treatment or welding, attention should be paid to the following issues: according to the process requirements, the workpieces need to be cleaned with organic solvents before being transferred to the heat treatment or welding process to remove s...
