What plane flies fastest?

At present, the fastest plane is: SR-7 1 Blackbird, a high-altitude high-speed reconnaissance plane of the US Air Force. The flying height reaches 30,000 meters and the maximum speed reaches 3.5 times the speed of sound, which is called "Double Three". Therefore, SR-7 1 flies higher and faster than most existing fighters and air defense missiles, so it is not really threatened by the "bullets" in the Soviet Union and China. During the reconnaissance of Israel's nuclear facilities over Israel, Israeli F-4 fighter planes fired AIM-9 rattlesnake air-to-air missiles, but the flying speed of the missiles was slower than that of SR-7 1. SR-7 1 is the first practical jet plane to successfully break through the "thermal barrier". "Thermal barrier" refers to the problem that when the aircraft speed reaches a certain level, friction with air will generate a lot of heat, thus threatening the structural safety of the aircraft. Therefore, titanium alloy with light weight and high strength is used as the structural material for the fuselage; The wing and other important parts are designed to adapt to thermal expansion, because when SR-7 1 flies at high speed, the fuselage length will be extended by more than 30 cm due to thermal expansion; The oil tank pipeline is ingeniously designed, adopting an elastic box body, and using the oil flow belt to increase the heat at high temperature. Although many measures have been taken, the oil tank will still leak to some extent after SR-7 1 landed, due to the thermal expansion and cold contraction of the engine block. In fact, SR-7 1 usually only needs a small amount of fuel when taking off, and refuels in the air after climbing to cruising altitude. The development of SR-7 1 began with 1959, the bullock cart project implemented by the US Air Force and Lockheed Martin Company. The original purpose of the plan is to design a fighter that can intercept at a high speed at an altitude of more than 20 thousand meters. 1962, the first test aircraft of the project, A- 1 1 (pictured left), was tested. In order to hide people's eyes and ears, the aircraft used the title of YF- 12 fighter in its publicity. After a large number of flight tests of A- 1 1 and the fire control and weapon systems added later, the US military decided that the fighter technology was not mature enough and gave up the plan. However, the excellent performance of A- 1 1 made the US military decide to use it as an improved high-altitude high-speed strategic reconnaissance plane, which made SR-7 1. The fire control and weapon system on A- 1 1 also laid a good foundation for the development of naval F- 14 fighters. The main difference in appearance between A- 1 1 and later SR-7 1 is that there is a cut between the side strip and the nose radome, while SR-7 1 does not. A- 1 1 has two crew members: the pilot and the weapon operator. The corresponding SR-7 1 also has two members: the pilot and the system operator. The cockpit is connected in series. Because the flight altitude and speed of SR-7 1 are beyond the human body's tolerance, the two members must wear fully sealed flight suits and look like astronauts. SR-7 1 is equipped with advanced electronic and optical reconnaissance equipment, but they are in absolute secrecy and little is known to the outside world. However, through the analysis of its flight speed and optical camera, it is considered that it can complete the optical photography reconnaissance task with an area of 324,000 square kilometers in 1 hour. Figuratively speaking, it only takes 6 minutes to take high-definition photos covering the whole of Italy. The performance of its optical lens is beyond ordinary imagination, but the resolution is highly confidential. In order to avoid the error caused by the forward flight of the aircraft (even if the shutter flashes, SR-7 1 will move forward for a certain distance. ), reconnaissance cameras are installed on the guide rail, and move backwards when shooting, so that the cameras are stationary relative to the ground. The SR-7 1 in the above picture is the only SR-7 1 trainer, nicknamed "Titanium Goose". The instructor sits in the back cabin, so the back cabin is higher than the front cabin, which gives the instructor a good view and is conducive to observing the surrounding environment. The picture below shows an SR-7 1 landing and releasing a huge orange parachute. Because the task of SR-7 1 is often to carry out long-range strategic reconnaissance, aerial refueling has become its daily routine. Of course, the endurance of SR-7 1 itself is also quite good. During the Cold War, the frequent flights of SR-7 1 included: Kadena base in Okinawa, Japan-North Korea; Turkey-Soviet Caucasus; Philippine-Lanzhou, China. Due to the high maintenance cost, SR-7 1 was retired in the late 1980s and transferred to NASA for high-altitude and high-speed scientific research, so the words NASA can be seen on the vertical tail. However, some Sr-7 1 re-served in the Gulf War. The picture below shows a "titanium goose" taking off. The engine sends out a pulsed high-temperature jet, and the edge strip and the wing tip pull out a white airflow vortex. SR-7 1 Pratt & Whitney J-58 axial flow engine with afterburner, maximum thrust of single engine 14460 kN. At present, most jet planes use turbofan engines, and the uniqueness of SR-7 1 is that the axial flow engine has excellent performance at high speed. There is a freely adjustable shock cone at the front end of the engine inlet to meet the different requirements of air intake when flying at different speeds. Basic technical data: captain 32.74m, aircraft height 5.64m, wingspan 16.95m, empty weight 27.24t, maximum takeoff gross weight 77. 18t, maximum speed M3.5 (altitude 25000m), cruising altitude 25900m and maximum range 5230km. All along, the X-43 is a dragon. Recently, NASA finally unveiled the mystery of the X-43A ultra-high-speed aircraft: this aircraft does not need rocket power, but its maximum speed can reach 10 times the speed of sound. It is the fastest plane in the world today, and it only takes half an hour to fly from the east coast of the United States to the west coast! American scientists call it the most important breakthrough in aviation technology since the Wright brothers first flew. However, scientists in other countries believe that this kind of aircraft has little chance of civilian use, and the real purpose of the United States to develop it is to deter other countries and consolidate its hegemonic position. Other countries have to guard against it. This is the X-43a of April 18. The wind in the desert of California is very strong, but the bad weather did not stop reporters from going to Edward Air Force Base, because NASA announced that it would show its carefully designed ultra-high-speed aircraft X-43a model for the first time at this base. According to NASA scientists, this X-43A is the most important breakthrough in aviation technology since the Wright brothers first flew. The model plane is parked on the asphalt runway at Edward base. When Joel Sizz, the executive director of NASA's X-43 project, pulled down the blue cloth covered on the X-43a, the reporters at the scene exclaimed: How beautiful! This small and exquisite plane looks like a surfboard. Then, Siz introduced some information about the X-43A to reporters. The new X-43A aircraft announced by NASA is powered by ramjet engine. Its fuselage is 3.7 meters long and black. Its top speed will be Mach 7, which is close to 8,047 kilometers per hour, equivalent to 7 times the speed of sound. It takes only half an hour to fly from the east coast of the United States to the west coast, thus breaking the record of the fastest jet engine without rocket power. In June 2005, NASA flew the fastest plane in the world. This new UAV, code-named X-43A, is about 3.65 meters long and weighs 1.2 tons. It looks like a black surfboard and the development cost is $230 million. The design maximum speed of the aircraft will reach 10 times the speed of sound, that is, 10 Mach! Unfortunately, during the first test flight, the X-43A crashed into the Pacific Ocean for several minutes with fish and shrimp, due to the booster failure. Scientific research also needs wave after wave. 165438+ 10, X-43A made another test flight. A modified B-52B heavy bomber took off from Edwards Air Force Base in California, with an X-43A plane and a Pegasus booster rocket under its wing. Soon, B-52B rose to the height of1.2000 meters. At this time, the Pegasus rocket bundled with the X-43A ignited, and they were separated from the B-52B bomber. The Pegasus rocket pushed the X-43A to an altitude of about 29,000 meters. Next, the X-43A broke away from the Pegasus rocket, ignited its own engine, and began to fly independently at a speed of 65,438+100,000 kilometers per hour. After about 10 seconds, the plane ran out of fuel, continued to taxi for 6 minutes, and fell into the Pacific Ocean after a distance of 1368 km. When falling into the sea, it was completely destroyed by the impact. This is a historic moment. The X-43A created a speed of Mach 9.7, which is unprecedented. World's fastest name: X-43a, maximum flight speed: 9.7 times the speed of sound. Time: June 2007 Flight test code: Hyper-X Origin: American UFO SR-7 1 Blackbird (SR-7 1 Blackbird) The people upstairs are really careless. The maximum speed of SR-7 1 is between Mach 3.2 and Mach 3.5. Blackbird, the first plane to break through the thermal barrier, X-43 X-431994165438+10. In October, the US government cancelled NASA's expensive NASP project, and the X-30 testing machine was immediately dismounted. In order to comply with the space strategy of "better, faster and cheaper", Hypersonic Experiment Program (Hyper-X) came into being, in which X-43 is its research core. There are four models of X-43, namely X-43A, X-43B, X-43C and X-43D, and its design speed target is Mach 7 to 10. X-43A and X-30 are not only very similar in appearance, but also adopt supersonic combustion ramjet with integrated fuselage. The precursor of the X-43A is designed to generate shock waves to compress the air entering the inlet of the supersonic combustion ramjet (installed under the fuselage). The X-43A testing machine has an advanced flat and compact fuselage, with a length of 3.6m, a wingspan of 1 .5m and a weight of about1ton. Because X-43A is a hypersonic ramjet, its fuel is liquid hydrogen carried on the plane, and its combustion improver (oxidant) is oxygen in the air, so it needs to fly into the air with the help of B-52 launch vehicle and booster rocket. In June, 200012000, the X-43A self-destructed in the air during its first test flight because the booster rocket deviated from its course. This catastrophic failure greatly delayed the test plan of the X-43A. It was not until March 27th, 2004 that the X-43A began its second test flight. B-52 dropped a booster rocket wrapped in X-43A in the airspace about 12000m from the Pacific Ocean, and then the booster rocket quickly climbed to an altitude of 28,500m. At this time, the X-43A was separated from the rocket and operated on its own supersonic combustion ramjet for about 10 second. The maximum speed is 8000km/h, which is equivalent to Mach 7, which is higher than Mach 6.72 created by X- 15A-2 testing machine powered by rocket. After that, the X-43A engine stopped, glided freely in the air for about 6 minutes, and then crashed into the Pacific Ocean near California as scheduled. The successful test flight of X-43A is of epoch-making significance. Because there is no need to carry all the fuel and accelerant like an airplane with rocket engine, an airplane with hypersonic ramjet engine can not only reduce its size, but also improve its payload. For example, in military applications, aircraft similar to the X-43A will be able to carry heavier attack weapons, and its smaller size will also make the enemy hard to prevent. X-43B will be tested before 20 10. Unlike the X-43A, it will use the combined power of a turbine engine and an air-breathing supersonic combustion ramjet. This novel combined power can automatically adjust the driving force and make the flight reach the optimal speed: when the speed of the aircraft is only about twice the speed of sound, the aircraft advances with the help of turbofan jet engine, just like ordinary aircraft; When the aircraft is flying at hypersonic speed (Mach number 5 to 15), the air-breathing supersonic combustion ramjet engine is used for propulsion. X-43C is used to verify the free flight performance of the aircraft equipped with supersonic combustion ramjet when accelerating from Mach 5 to Mach 7, and the performance of supersonic combustion ramjet in stamping negative charges. The engine used has two working modes: ordinary ramjet and supersonic ramjet, and it is expected to be tested in 2008. The development of X-43D is also in progress. It will be equipped with a dual-mode supersonic ramjet engine for cooling hydrogen fuel, which can increase the speed of the X-43D to Mach 15. Successful ones are: SR-7 1 and MIG -25, M3.0, all of which have broken through the thermal barrier, but MIG -25 is stronger. Conventional layout can fly so fast in actual combat, and the experiment is X43. If the space shuttle is also an airplane, it means that the only space shuttle in service is "SR-7 1 Blackbird". The blackbird upstairs has long since retired. Of course, the fastest flight is the X-43A, another masterpiece of NASA. X 15 elephant rocket launched in the air. It must be SR-7 1 blackbird that can bring people. X-43 American F-22A Raptor (the fourth generation fighter) x-43a.
