Leading vertical/short takeoff and landing fighter - AV-8B Harrier II As a joint masterpiece of McDonnell Douglas (now Boeing) and BAE Systems, the AV-8B Harrier II has become a leader in global air power with its excellent performance and all-weather over-the-horizon attack capability.
US AV-8B fighter AV-8B fighter is developed by the United States on the basis of the Harrier fighter, which has almost no need for take-off and landing sites, and can easily complete vertical take-off and landing. Initially, the U.S. Marine Corps willThis aircraft is treated as the main force, giving it the close-range fire support responsibility.
The AV-8B is a short take-off/vertical landing attack aircraft produced by McDonnell Douglas, nicknamed the Sea Harrier. The original design of the AV-8B was derived from the British Harrier 1 attack aircraft, produced in the United States under the designation AV-8A, which first flew on 9 November 1978. The performance of the AV-8A attack aircraft does not fully meet the needs of the United States Marine Corps, especially in terms of payload.
Although the AV-8B is introduced, after modification, it still has some achievements in most people's eyesChina, the United States military equipment is their own research and development, because the United States has a strong technology, so some of the United States military equipment technology is blocked, because of fear that other countries will get their technology, the production of the same military equipment, such a situation, the United States naturally is not willing to see.
The U.S. Marine Corps purchased 102 AV-8As, all equipped by 1977. AV-8B is an improved version of AV-8A, jointly developed by the United States and the United Kingdom, equipped with the United States Marine Corps called AV-8B Harrier II, equipped with the British Air Force called "Harrier" GRMK5. Made in 198First flight in November, 1989 began to equip the army, the United States armed with various types of AV-8B a total of 235. In addition to the United States and the United Kingdom, Spain and Italy are also equipped with the aircraft.1, M means that the wireless router can only support 300M bandwidth, that is, even if the network speed is 1G, after 300M router out only 300M. Where M is short for Mbps, bit rate is used to describe the speed of data transmission is a unit, bitThe higher the rate, the faster the flow rate. In theory, 300Mbps network speed, the transmission speed per second is 35MB/S.
2, the frequency bands represented by the two are not the same. 1167M refers to the 4G frequency band, 300M refers to the 5G frequency band. 2, there is a difference in the Internet speed between the two 1167M Internet speed is about 300Mbps, 300M Internet speed is about 867Mbps, this Internet speed for general wifi equipment is no difference.
3, G is the wireless transmission frequency. 300M is the maximum transmission speed. Download speed exceeds second>
2, GY refers to outdoor laminated cable, A refers to aluminum armor, so GYTA is outdoor laminated armored cable (aluminum armor), S refers to steel armor, 12 is the number of wires of the cable, B refers to single mode (A is multi-mode). The GYTA cable is constructed by placing 250μm fiber in a loose tube made of a high-modulus material and filling the tube with a waterproof compound.
3. What is the meaning of cable gyta? gyta refers to one of the armored optical cables, its full name is optical cable (G) armored (Y) mixed fiber (T) aluminum-plastic composite (A) outer sheath. Compared to unarmoured cable, gytaCable has higher protection and protection performance, can be used in harsher environments. The construction of gyta cable is composed of optical fiber, padding, metal cable core, jacket, packing tape and protective layer.
