What plane flies the fastest?

The fastest aircraft currently are: SR-71 "BlackBird", a high-altitude and high-speed reconnaissance aircraft of the United States Air Force. The flight altitude reaches 30,000 meters and the maximum speed reaches 3.5 times the speed of sound, which is called "double three". Therefore, the SR-71 can fly higher and faster than most existing fighter jets and anti-aircraft missiles. Therefore, entering and exiting the enemy's airspace is like entering uninhabited territory, and it has not faced any real threats in the "rain of bullets" from the Soviet Union and China. ; While scouting Israeli nuclear facilities over Israel, Israeli F-4 fighter jets launched AIM-9 Sidewinder air-to-air missiles at it, but the missiles flew slower than the SR-71. The SR-71 was the first practical jet aircraft to successfully break through the "heat barrier." "Thermal barrier" refers to the problem that when the aircraft speed reaches a certain level, friction with the air generates a large amount of heat, thus threatening the safety of the aircraft structure. To this end, the fuselage uses low-weight, high-strength titanium alloy as the structural material; important parts such as the wings are designed to adapt to thermal expansion, because when the SR-71 is flying at high speed, the length of the fuselage will extend by more than 30% due to thermal expansion. cm; the fuel tank pipeline is cleverly designed, using an elastic box body, and uses the flow of oil to take away heat from high-temperature parts. Although many measures have been taken, after the SR-71 lands on the ground, the fuel tank will still leak to a certain extent due to the thermal expansion and contraction of the body. In fact, the SR-71 usually takes off with only a small amount of fuel, and then refuels in the air after climbing to cruising altitude. The development of the SR-71 began with the OXCART program implemented by the U.S. Air Force and Lockheed Martin in 1959. The original purpose of the plan was to design a fighter capable of high-speed interception at an altitude of more than 20,000 meters. In 1962, the program's first test aircraft, the A-11 (pictured left), took flight. In order to deceive others, the aircraft was promoted as the YF-12 fighter. After a large number of test flights on the A-11 and later installed fire control and weapons systems, the US military believed that the fighter technology was not mature enough and gave up the plan. However, the excellent performance of the A-11 led the US military to decide to use its improved version as a high-altitude, high-speed strategic reconnaissance aircraft, which resulted in the SR-71. The fire control and weapons systems on the A-11 also laid a good foundation for the later development of the Navy's F-14 fighter jet. The main appearance difference between the A-11 and the later SR-71 is that there is a cutout between the side strip and the nose radome, while the SR-71 does not. The A-11 has a crew of two: pilot and weapons operator. The corresponding SR-71 also has two members: pilot and system operator. The cockpit is in tandem configuration. Since the flight height and speed of the SR-71 are beyond the endurance range of the human body, the two members must wear fully sealed flight suits that look similar to astronauts. The SR-71 is equipped with advanced electronic and optical reconnaissance equipment, but they are kept strictly confidential and little is known to the outside world. However, through analysis of its flight speed and optical cameras, it is believed that it can complete an optical photography reconnaissance mission over an area of ??324,000 square kilometers within one hour. To put it bluntly, it only takes 6 minutes to take high-definition photos covering the entire Italy. The performance of its optical lens is beyond ordinary imagination, but the resolution is highly confidential. In order to avoid errors caused by the forward flight of the aircraft (even if the shutter flashes for a moment, the SR-71 will move forward for a considerable distance), the reconnaissance cameras are installed on the guide rails and move backward when taking pictures, so that the camera at rest relative to the ground. The SR-71 in the top picture is the only SR-71 trainer aircraft, nicknamed "Titanium Goose". The instructor sits in the rear cabin, which is higher than the front cabin, allowing the instructor to have a good line of sight and help observe the surrounding environment. The picture below shows an SR-71 landing and releasing a huge orange parachute. Since the mission of the SR-71 is often long-range strategic reconnaissance, aerial refueling has become commonplace for it. Of course, the battery life of the SR-71 itself is also quite good. During the Cold War, the SR-71's frequent flight routes included: Kadena Base in Okinawa, Japan - North Korea; Turkey - the Caucasus region of the Soviet Union; Philippines - Lanzhou, China. Due to high maintenance costs, the SR-71 was retired in the late 1980s and transferred to NASA for high-altitude and high-speed scientific research, so you can see the word NASA on the vertical fin. However, some SR-71s were returned to service during the Gulf War. The picture below shows a "Titanium Goose" taking off. The engine emits pulse-like high-temperature jets, and white air vortices are drawn out of the side strips and wing tips. The SR-71 uses Pratt & Whitney's J-58 axial-flow engine with a rear afterburner, with a maximum thrust of 14,460 kN per unit. At present, most jet aircraft use turbofan engines. The uniqueness of the SR-71 is that the axial flow engine has excellent performance during high-speed flight. There is a freely adjustable shock cone at the front end of the engine air inlet to adapt to the different requirements for air intake when flying at different speeds.

All along, X-43 has always been a dragon that has seen its beginning but not its end. Recently, NASA finally unveiled the mystery of the X-43A ultra-high-speed aircraft: This aircraft does not require rocket power, but can reach a top speed of 10 times the speed of sound. It is the fastest aircraft in the world today, flying from the east coast of the United States to The west coast only takes half an hour! American scientists called it the most significant breakthrough in aviation technology since the Wright brothers' first flight. However, scientists from other countries believe that the chance of civilian use of this aircraft is very small, and the real purpose of the United States in developing it is to deter other countries and consolidate its hegemony. Other countries have to take precautions. This is the X-43A. On April 18, the California desert was very windy, but the bad weather did not stop journalists from all walks of life from going to Edwards Air Force Base, because NASA announced that it would display its aircraft to the outside world for the first time at this base. A carefully designed model of the ultra-high-speed aircraft X-43A. According to NASA scientists, the X-43A is the most significant breakthrough in aviation technology since the Wright brothers' first flight. The model aircraft was parked on an asphalt runway in Edward Base. When Joel Sizzi, executive officer of NASA's X-43 program, pulled down the blue cloth covering the X-43A, the reporters at the scene all exclaimed: It's so beautiful! This small and exquisite aircraft looks a lot like a surfboard. Then, Sitz introduced some information about the X-43A to the reporters. The new X-43A aircraft announced by NASA is powered by a ramjet engine. The fuselage is 3.7 meters long and is black. Its top speed will be Mach 7, which is nearly 8,047 kilometers per hour, which is equivalent to 7 times the speed of sound. The flight from the east coast to the west coast of the United States takes only half an hour, thus breaking the record for the fastest jet engine without rocket power. In June 2005, NASA flew one of the fastest aircraft in the world. This new type of drone, codenamed X-43A, is about 3.65 meters long and weighs 1.2 tons. It looks like a black surfboard and cost US$230 million to develop. The aircraft is designed to reach a maximum speed of 10 times the speed of sound, which is Mach 10! Unfortunately, during the first test flight, due to the failure of the booster, the X-43A fell into the Pacific Ocean a few minutes after takeoff and became company with fish and shrimps. Scientific research also needs to be continued. In November, the X-43A flew again. A modified B-52B heavy bomber took off from Edwards Air Force Base in California with an X-43A aircraft and a Pegasus booster rocket hanging under the wing. Soon, the B-52B rose to an altitude of 12,000 meters. At this time, the "Pegasus" rocket bundled with the X-43A was ignited, and they 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 separated from the Pegasus rocket, ignited its own engine, and began to fly independently at a speed of 10,000 kilometers per hour. About 10 seconds later, the plane ran out of fuel and continued to glide for 6 minutes, covering a distance of 1,368 kilometers and crashing into the Pacific Ocean. It was completely destroyed by the impact of falling into the sea. This is a historic moment. The X-43A created a speed of Mach 9.7, unprecedented. It is the fastest in the world. Name: SR-71 "Blackbird" (SR--71 "Blackbird" high-altitude reconnaissance aircraft, the legendary speed is Mach 12 Mach 12? The people upstairs are really brave, the top speed of SR-71 is Mach 3.2 ~ 3.5 Between. Blackbird, the first aircraft to break the thermal barrier X-43 In order to comply with the "better, faster, cheaper" aerospace strategy, the US Hypersonic Test Program (Hyper-X) program came into being, of which the X-43 is the core of its research. The X-43 program has four models. Namely, X-43A, X-43B, X-43C and X-43D, their design speed targets are Mach 7 to Mach 10. X-43A and X-30 are not only very similar in appearance, but also use mechanical engines. The forward fuselage of the X-43A is designed to generate a shock wave to compress the air entering the scramjet inlet (mounted under the fuselage). The test aircraft has an advanced flat and compact fuselage, with a fuselage length of 3.6 meters, a wingspan of 1.5 meters, and a weight of approximately 1 ton. Since the X-43A uses a hypersonic ramjet engine, its fuel is liquid hydrogen carried on the aircraft. The accelerant (oxidant) is oxygen in the air, so it needs to be flown into the air with the help of a B-52 carrier aircraft and a booster rocket.

In June 2001, during its first test flight, the X-43A had an emergency self-destruction in the air due to the booster rocket deviating from its course and rolling over. This disastrous failure greatly delayed the X-43A test plan. It was not until March 27, 2004 that the X-43A began its second test flight. The B-52 carrier aircraft dropped the booster rocket "wrapping" the X-43A in the airspace about 12,000 meters above the Pacific Ocean, and then the booster rocket quickly climbed to an altitude of 28,500 meters. At this time, the X-43A separated from the rocket and relied on its own supersonic combustion ramjet engine to work for about 10 seconds. The maximum speed reached 8,000 kilometers per hour, equivalent to Mach 7, which has exceeded the rocket-powered X-15A. -2 Mach 6.72 created by the test machine. After this, the X-43A engine stalled, and after gliding freely in the air for about 6 minutes, it crashed into the Pacific Ocean near California as planned. The successful test flight of the X-43A is of epoch-making significance. Unlike aircraft using rocket engines, which must carry all fuel and combustion accelerants, aircraft using hypersonic scramjet engines can not only reduce their own size, but also increase the payload capacity of the aircraft. . For example, in military applications, aircraft similar to the X-43A will be able to carry heavier strike weapons, and their compact size will also make them difficult for enemies to detect. The X-43B will fly before 2010, and unlike the X-43A it will be powered by a combination of turbine engines and air-breathing scramjet engines. This novel combination of power can automatically adjust the propulsion used to achieve the optimal speed of flight: when the aircraft's speed is only about twice the speed of sound, the aircraft moves forward with the help of a turbofan jet engine, which is no different from an ordinary aircraft; when the aircraft is only about twice the speed of sound, When flying at hypersonic speeds (Mach 5 to 15), it begins to use an air-breathing supersonic combustion ramjet for propulsion. The X-43C is used to verify the free flight performance of an aircraft equipped with a scramjet engine when accelerating from Mach 5 to Mach 7 and the negative charge performance of scramjet engines. The engines used include ordinary ramjet engines and scramjet engines. The two working modes of the engine are expected to be tested in 2008. Work is also underway on the X-43D, which will be equipped with a dual-mode scramjet engine that cools hydrogen fuel and can increase the X-43D's speed to Mach 15. The ones that formed the army are: SR-71, MIG-25, and M3.0. They all broke through the thermal barrier, but the MIG-25 is more powerful. It can fly so fast with the conventional layout. The actual one is the SR71, and the experimental one is the X43. If you think of the space shuttle If it is an aircraft, it would be the space shuttle. Only the "SR-71 Blackbird" currently in service is the fastest, with a top speed of 3.5M per hour, and even Sidewinder missiles cannot catch it! Upstairs, the "Blackbird" has long been retired. The fastest flying one is of course the X-43A, another masterpiece of NASA. The X15 looks like a rocket for airborne launch.

The one that can seat people must be the SR-71 Blackbird high-altitude and high-speed reconnaissance aircraft X-43 American F-22A "Raptor" fighter (fourth generation fighter) x-43a
