[China Aluminum Network] U.S. military develops ultra-quiet electric motorcycle
Soldiers ride ultra-quiet electric motorcycles can quickly and quickly approach the enemy, giving the enemy a surprise attack. According to a report by the US “Stars and Stripes†on June 1, 2017, this type of motorcycle has been successfully developed and is close to service. It was developed and manufactured by American Rogos Technologies. They have been developing a hybrid off-road motorcycle called the Silent Eagle, and are currently developing hybrid motorcycles with all-electric motorcycles and a lighter air-cooled engine. Ultra-quiet electric motorcycles must be sturdy and as light as possible, and should be front-wheel-drive to make it easier to drive in steep mountains and sand, or to provide greater traction when driving on the beach. At present, titanium, aluminum and composite materials are the basic materials for manufacturing such motorcycles. Titanium or composite materials are used for key components, and secondary components can be made of high-strength 7075 alloy or 7078 alloy.
The prototype of the "Silent Eagle" motorcycle is an amusement type off-road motorcycle. Its cost is 15,000 yuan and its quality is 121kg. The ultra-quiet electric motorcycle will be heavier if it adds some functions, but it will not exceed 135kg. The cruising range is 80km.
Aluminium: Achieving China Global
Fast amphibious armored car
According to the British "Daily Mail" website (June 9, 2017) and China's "Reference News" on June 11, 2017, China is developing a faster-speed amphibious armored vehicle in the world. It is made of lightweight materials. What light material is used is not described in the report, but it is nothing more than one of the four commonly used lightweight materials (aluminum, magnesium, titanium and composite materials). From the current technical situation, aluminum alloy is used to manufacture amphibious armored vehicles. The preferred material, because it has a better price/performance ratio, amphibious armored vehicles must run on land, but also be able to travel in rivers, lakes, seas, must have strong resistance to various types of water, and at the same time meet the premise of structural performance Next, it should have a density as low as possible to reduce the net mass of the car, so it can be said that its boat-shaped shell is welded with 5XXX series aluminum alloy plate, and its armor plate is also processed with aluminum alloy plate. of.
The five-wheeled amphibious armored vehicle developed by China has a high speed of 50km/h in calm water, far ahead of the 9.7km/h speed of the faster amphibious armored vehicle in the United States. It is about 4.2 times faster than the latter. At a more advantageous level.
This amphibious armored vehicle was developed by Beijing North China Vehicle Research Institute and manufactured by China North Industries Corporation. The body is V-shaped, which can not only significantly reduce the resistance of water flow, but also help to resist the attacks of improvised explosive devices. Its wheels are retractable, and small water jet propulsion devices are installed next to the wheels to help the vehicle reach its destination faster and faster.
With its unmounted or unarmed weapons, the car weighs only 5.5 tons, which is the result of its sophisticated design and aluminum alloy materials. The China Defense Blog reports: “Even if it is equipped with armor and carrying full width Mass production version of the weapon, it is likely to still reach 18km/h - 28km/h amphibious driving speed."

BMD Airborne Chariot is made of aluminum alloy
Russia's airborne chariot BMD, the U.S. "National Interest" bimonthly website called it "flying" armored vehicles and is a secret weapon of the Russian military. It was based on the BMP-1 infantry fighting vehicle introduced by the Soviet Union in 1966. Made after. The BMP-1 Infantry Fighting Vehicle is an airborne aircraft that can be used to provide mechanized infantry with the load of the ground force and the ground force. It is equipped with a machine gun, an anti-tank missile launcher and a 173 mm low-pressure gun.
The volume of the BMD-1 chariot produced by Volgograd in Russia is smaller than the imported BMP-1 chariot and its lighter weight, because its outer shell is made of aluminum alloy, and the hanging armor should also be aluminum alloy. The board is thick, and its weapon has not been reduced at all, and two machine guns are additionally provided on both sides of the front of the vehicle. The quality of the BMD-1 tank is only 8 tons. Its front length is obviously shorter than that of the BMP-1 model. Its highway speed is 80km/h, which is 25% faster than that of the BMP-1 model.
As early as the Soviet period, a special rocket parachute was designed and manufactured for this type of airborne vehicle. The touch stick suspended from the bottom of the BMD chassis touches the ground and triggers a retrograde rocket, reducing the final landing speed to a safe level. 6m/s.
Russia is building four airborne divisions, each with 6,500 troops, and it is equipped with 330 BMD-1 vehicles. In addition to the BMD-1 type tank in Russia, the Volgograd tank manufacturing plant currently produces dozens of BMD-4M and BTR-MDM armored personnel carriers each year. Because of its amphibious combat capability, this new type of tank will serve the Russian Marine Corps.
The key component of an airdrop tank recently produced by China Jiangbei Industry Group Jiangbei Mechatronics Co., Ltd.—the reducer housing is forged by Jiangsu Haoran Spray Forming Alloy Co., Ltd. with spray forming 7055 alloy. It is said that Jiangyan Company will use spray-formed 7055 aluminum alloy parts on a large number of new air-drop tanks and amphibious armored vehicles that will be developed and produced soon.
7055 alloy is a kind of high-strength alloy, it is a kind of American alloy. It was registered in American Aluminum Corporation in 1991. Its calibration composition (mass%): 0.10Si, 0.15Fe, 2.0Cu - 2.6Cu, 0.05Mn, 1.8 Mg - 2.3 Mg, 0.04 Cr, 7.6 Zn - 8.4 Zn, 0.06 Ti, 0.08 Zr - 0.25 Zr, other impurities alone 0.05, total 0.15, remaining Al.
Chinese "Black Whirlwind" Armed
Helicopter aluminum dominates
China’s newly developed Straight-19E is a light-armed helicopter. It was first publicized in Harbin, Heilongjiang on September 8, 2015. It was solely developed by China Aviation Industry Corporation and manufactured by Harbin Aircraft Industry Group Co., Ltd. It is an exporter. Type of narrow body two dedicated helicopter gunships.
According to the report, Zhi-19E is an improved version of the Zhi-19 helicopter gunship. The latter is 12m long and 4.01m high, with a large take-off mass of 4.5 tons, a cruising speed of 245km/h, a high speed of 305km/h and a range of 800km. The Straight-19E is a light-armed helicopter with a large take-off quality of >4 tons. Its own light weight has obvious advantages in terms of cruising speed and climb rate. It can destroy more powerful tanks and other ground targets around the world, and is also suitable for Ground forces provide air support or defense against other low-level flying targets and have excellent operational performance. In the straight-to-19E structural materials, although some composite materials are used, the aluminum alloy still dominates, accounting for more than 60%, and 4 air-to-surface missiles are mounted thereon, as well as multiple rocket launchers. In a very short period of time, a dozen rockets were inclined toward the enemy.
There is no aluminum powder
The "Father of the Bomb" and the "Mother of the Bomb"
The so-called "Father of the Bomb" or "Mother of the Bomb" is their giant bomb with an explosive equivalent of more than 10 tons of TNT. The United States made a large bomb with an equivalent weight of 11 tons of GBU-43/B more than a decade ago. It was the larger bomb at the time and people called it "the mother of bombs." Not long ago, the United States launched a "mother of bombs" (MOAB) at A-rich juice, destroying a series of cave facilities built by the "Islamic State." On September 7, 2017, the Russian Air Force sent a command to a command post and a communications center in the “Islamic State†of Deir Ezor in Syria to bomb the world’s larger bomb so far, equivalent to 44 tons of TNT equivalent. It is the "father of bombs" to distinguish it from the "mother of bombs" in the United States. TNT is an abbreviation for trinitro-toluene. It is often referred to as TNT or yellow explosive. Conventional explosives contain such explosives. Generally, they are only loaded with tens to hundreds of kg.
This "father of the bomb" not only killed an organization and a communications center of the "Islamic State" organization in one fell swoop, but also killed more than 40 militants, including the "war minister" of the "Islamic State" organization. Gulmud Khalimov and the main commander Mohammed Shemari.
Why is the mother of the bomb and the father of the bomb so powerful? Because they are hot-pressed weapons, officially known as air-explosive hot-boost enhanced bombs, the internal explosives are a mixture of fine ethylene oxide powder and aluminum powder, which will be blasted in the air after being thrown, and the mixture will be thrown into the air. The formation of a huge explosive cloud immediately detonated, in addition to the high temperature released by the explosion, it will also produce a deadly pressure wave, which has a significant destruction effect on closed fortifications such as Tan caves and bunkers.
Some people think that the power of the “father of bombs†can rival that of tactical nuclear weapons. Although this perception is somewhat exaggerated, it is not nonsense because of the lethality and tactics of the “father of the bomb†with an explosive equivalent of 44 tons. The difference between nuclear weapons is not very great. The equivalent weight of W48 warheads of the US 155mm M454 nuclear shell is 70 tons - 100 tons.
The "father of bombs" or "mother of bombs" cannot use ordinary bombers, and must use modified aircraft suitable for investing in these two types of bombs. Britain’s “Mother of Bombs†invested in Afghanistan. They were all put in the loading and unloading ramps of the modified C-130 Hercules transport aircraft. Russia’s 2007 test vehicle for the “Father of the Bomb†was An Air Force Tu-160 "Jolly Roger" bomber, but this time in Syria, from the video point of view was also dropped from the loading ramp of a transport aircraft.
According to existing media reports, although China has not yet seen China develop explosive bombs such as "the mother of bombs" and "the father of bombs", China has also made extraordinary achievements in the development of air bombs. At the 2012 Zhuhai Airshow, China Weapons Group exhibited a 1:1 solid model of the CS/BB F-1 250kg air-fuel bomb. According to the data, the bomb is mainly used to combat non-hard (soft) targets and semi-rigid targets that are sensitive to the ultra-high pressure of the shock wave on the ground or water. The damage function mainly consists of secondary detonation of ethylene oxide powder and aluminum powder. Mixed cloud clusters, or explosive aluminum heat reaction of liquid mixtures of ammonium nitrate and aluminum nitrate and chemical reactions with air, resulting in high energy density, large area of ​​damage, and many other damage factors.
According to the air show site staff, the 250kg class air blast is not small, and it can be put by the H-6 and IL76. It can be seen that domestically produced large-scale fuel air bombs should be comparable to the US BLU-82. The BLU-82 bomb is the larger bomb used by the United States on the Vietnam battlefield in 1970. It is 360 cm long, 140 cm in diameter, weighs 6.8 tons and contains 5.715 tons of nitric acid. The colloidal explosive consisting of ammonium, aluminum powder and polystyrene fatty acid can produce an ultra high pressure of 70kg/cm2 in the explosion and the diameter is in the range of 60m. All the dents will disappear, and all combustibles within a few hundred meters will be melted. It is ashes and can cause people in the range of 160m in diameter (about 8722m2 area) to lose combat effectiveness. The launch height of BLU-82 air explosive bomb is ≥2000m, and it has a small decelerator at the tail.
China's CS/BBF-1 bomb is close to the production year, its tail is on the tail wing and the control wing for accurate guidance, so it has at least the inertial guidance capability. The air-burning bombs create a vacuum environment through the overpressure and extreme temperature generated during the explosion to extinguish all life targets within the explosion range. Even if there are no shrapnel, the explosion zone is still a ruin in the end, but the rescue personnel can enter after the explosion. .
