More than 10,000 kilometers per hour! The world's fastest aircraft is now setting a new record.
On November 17, Beijing Evening News reported that NASA successfully conducted a flight test of the unmanned hypersonic test aircraft X-43A on November 16 local time in California (early this morning Beijing time). The X-43A test aircraft flew at a speed of more than 10,000 kilometers per hour, which is twice the speed of sound, thus breaking the record set by an X-43A test aircraft of the same model in March this year, and once again setting a record for the highest flight speed of the aircraft. Yesterday afternoon local time, the X-43A test plane was carried by a modified B-52 aircraft to an altitude of 10,000 meters at Edward Air Force Base in the desert north of Los Angeles, California.
In aerodynamics, such a high-speed flight is called "hypersonic flight". NASA's X-43A program, which aims to build an aircraft that can reach the edge of the Earth's atmosphere, has a planned development period of eight years and a research budget of $100 million.

1. The aircraft ranges from 200-4000 kilometers per hour; The general civilian airliner is about 800 kilometers, the small passenger plane is about 500 kilometers, and the fighter jet is about 1000 kilometers. The speed of a civil airliner is generally 900 km/h. The Boeing 737 can reach a cruising speed of almost 918 km h.
2. The Boeing 747 is the fastest to cruise, and it can reach Mach 1120km, which is the fastest.
3. An airplane refers to a heavier-than-air aircraft that is heavier than air flying in the atmosphere by generating forward thrust or pull force from the power unit and generating lift force by the fixed wings of the fuselage.

The flight speed of the aircraftFor different aircraft, its flight speed is also different, among which the flight speed of civilian passenger aircraft is 700-1000 kilometers per hour, while the flight speed of small passenger aircraft refers to the flight speed of 400-500 kilometers per hour, and the flight speed of some fighters is about 1000 kilometers per hour.
A brief introduction to the aircraftAirplanes were one of the most important inventions of the early twentieth century, which can be said to have changed the way people traveled, etc. Airplanes can be classified according to their use, and the main bucket is divided into military aircraft and civilian aircraft.
Among them, military aircraft include fighter planes, attack planes, bombers, reconnaissance planes, transport planes, early warning planes, and so on.

Helicopters travel at around 250 km/h, airliners are around kilometres per hour, and fighter jets can reach up to 6,000 km/h. The speed of the aircraft depends on many factors, such as the condition of the aircraft itself, weather conditions, flight altitude, etc. <
Helicopters travel at around 250 km/h, airliners are around kilometres per hour, and fighter jets can reach up to 6,000 km/h. The speed of the aircraft depends on many factors, such as the condition of the aircraft itself, the weather conditions, the flight altitude, etc., generally the higher the altitude, the faster the flight, because the high-altitude air is thin and the resistance is small, and if the low-altitude flight is too fast, it will cause damage to the body, and the air is also an invisible hand, and too much overspeed will even disintegrate directly.
-
The aircraft travels 200-6000 kilometers per hour.
Generally, the speed of a helicopter is about 250 kilometers per hour, that of a passenger plane is about one kilometer per hour, and that of a fighter is about 6,000 kilometers per hour. And the speed of the aircraft depends on many factors, such as the condition of the aircraft itself, the weather conditions, the flight altitude, etc.
The take-off of an airplane depends on the lift generated by the relative motion with the air, and the magnitude of the lift depends on the relative speed of the aircraft with the air, not the relative speed of the aircraft with the ground. If taking off against a headwind, the aircraft taxiing speed is opposite to the direction of the wind speed, and the relative velocity of the aircraft and the air is equal to the sum of the two. At this point, the aircraft only needs a small glide speed to get the lift it needs to get off the ground.
As a result, the distance required to take off against the wind will be shorter than if it were to take off without wind. Conversely, if taking off downwind, the aircraft needs to reach a higher taxiing speed to get the lift required from the ground, and the glide distance is relatively longer.

Hello dear: The speed of an airplane is usually expressed in kilometers per hour (km h). Depending on the aircraft type and flight conditions, the speed of the aircraft may vary.
Here are some common aircraft speed ranges:1Commercial airliners:
The cruising speed of commercial airliners is usually between 800 and 900 km h. 2. ***:
The cruising speed is usually between 200 and 240 km h. 3.Military Jet Fighter Socks:
Military jet fighters typically have a maximum speed of more than 2000 km Supersonic aircraft: Supersonic aircraft, such as the jetliner Bombardier CRJ-700 and the supersonic airliner Bombardier CRJ-900, can have a maximum speed dismantling of more than 900 km h and even reach sound barrier speeds (about 1235 km h). Please note that these are just some of the common aircraft speed ranges, which depend on the design and performance of the aircraft.
In addition, aircraft speed can also be affected by factors such as climatic conditions, flight altitude, load, etc. The following extension on this will hopefully help you: The speed of the aircraft is one of the key indicators of the aircraft's performance, and different types of aircraft have different speed characteristics.
Commercial airliners are typically dominated by high-speed cruising in order to quickly transport passengers and cargo from one place to another. The speed is relatively low, but it has the ability to take off and land vertically, making it suitable for tasks that require operation in tight spaces. Military jet fighters and supersonic aircraft have higher speeds to meet operational demands.
The unit of measurement for aircraft speed is generally kilometers per hour (km h), which is an internationally accepted unit. In addition to kilometers per hour, there are other units of flight speed, such as miles per hour (mph) and knots (knots). Different countries and regions may use different units to express aircraft speed, but kilometers per hour are one of the most common and widely used units.
Aircraft speed calculations are usually monitored and displayed in real-time through flight instruments and navigation systems. The pilot will control the speed of the aircraft according to the flight mission and aviation regulations to ensure the safety and efficiency of the flight. All in all, the speed of an aircraft is diverse and depends on the aircraft type, design, and performance, as well as the influence of other external factors.

The fastest is the American "Blackbird" high-altitude reconnaissance aircraft, which is about 4 times the speed of sound.
The slowest is *** and the slowest VTOL aircraft can be as slow as 0 5 km as well as hovering.
The average speed of a commercial airliner is about 400,500 miles per hour, and the Boeing 737-400 flies at a speed of 300,350 nautical miles per hour.
In the past, the Concorde could reach speeds of up to 1,800 hours (already above the speed of sound), and small single-engine propellers (such as the Cessna-172) flew at speeds of about 100 miles and hours.
Airplanes are heavier-than-air aircraft, so they need to expend their own power to gain lift. And the ** of lift is the effect of air on the wing in flight. The upper surface of the wing is curved and the lower surface is flat, so when the wing is in relative motion to the air, the air flowing through the upper surface travels a distance (s1) in the same time (t) than the air flowing through the lower surface (s2), so the relative velocity of the air on the upper surface is faster than the air on the lower surface (v1 = s1 t> v2 = s2 t1). >>>More
Yes, super-high-speed vehicles are not science fiction. At present, there are three kinds of cars in the world that can reach speeds of 4,000 kilometers per hour >>>More
I have to say that the price rate is getting faster and faster, and many residents are reflecting that the price is too fast, and the social pressure is too huge, which is indeed not something that ordinary people can afford. Street shared charging treasure has been favored by many people, but the initial price increase from one yuan per hour to four yuan per hour, this price increase is a bit too large. <> >>>More
Lack of power: Some friends do not wear the watch every day, or wear it for a short time every day, which leads to the lack of power of the automatic watch and the watch does not go. Automatic watches wind the watch by moving the arm, and if you don't exercise enough or don't wear it, the watch won't go. >>>More
The ** of reverse osmosis equipment is generally more than 10,000 yuan, and the ** of reverse osmosis equipment is mainly due to its own technology and different uses. The composition of a reverse osmosis equipment generally includes pretreatment, reverse osmosis, post-treatment, cleaning, electrical control, etc., and the rising cost of each component may lead to the rise of reverse osmosis equipment.
