Question 1: On rainy days, how high are the clouds in the sky above the ground? The atmosphere, from the ground to high altitudes, can be simply divided into three layers: the troposphere, the stratosphere, and the upper atmosphere. The thickness of the troposphere is 12 kilometers above the equator and can reach 18 kilometers from the ground at high altitudes. At the north and south poles, wind, clouds, rain and snow all occur. this layer. The clouds, rain and hail on the earth are all in this layer, but there are high and low heights, as if rain can occur at a height of several hundred meters. Of course, the hail is a little higher, but it. can't be above 18 kilometers! The stratosphere is from the tropopause to a height of 50 to 55 kilometers. The weather here is clear and the visibility of the atmosphere is good. This is the altitude at which planes fly higher than here. Eastthe upper atmosphere. At an altitude of 250 kilometers, the air is very thin
Question 2: How high are the clouds above the ground? One barrel of crude oil = 0.1576 thousand liters (cubic meters), one ton = 7.3 barrels
One kilogram = 0.3055 gallons (US) and 0.2545 gallons (British), so one barrel of international crude oil = 136.986 kilograms. In the general market, 137 kilograms will prevail. My response determines the standard. You have no right to slap me, I will not mislead others.
Question 3: How. how many meters is the distance between the ground and the clouds? How high can a plane usually fly? Clouds can extend from 50 to over 20,000 meters. During the 1984 military parade, the clouds were lower than the roof of the Air Force building. Less than 50 meters. This is what a former Air Force executive said on CCTV7 when talking about the military paradesilence of 1984 while we were talking about this year's military parade.
Cloud cover did not exceed 200 meters during the British air raid on Dresden.
Ordinary white clouds are not a problem, but flying inside them will affect visibility. are like a thick fog. They are all made of water vapor. Because they are relatively large, a ground cloud can affect a city.
But this is not possible with dark clouds and cumulonimbus clouds, which can contain negative positrons and electrons. If they hit a plane, it will be destroyed and everyone will die. The Space Shuttle flies the highest, and apart from it, only high-altitude reconnaissance aircraft fly the highest
The SR-71 supersonic high-altitude reconnaissance aircraft is a strategic reconnaissance aircraft M3 developed by the American Lockheed. US Air Force Enterprise. In 1959, Lockheed secretly developed a military aircraft with the number M 3 at the request of the US Air Force, numbered A-11. It is the prototype of the YF-12 and SR-71 combat aircraft. Development of the YF-12 was stopped.
The SR-71 began development in February 1963, began test flights in December 1964, was delivered for use in January 1966, and was retired in 1990. However, during the war of the Gulf, it was replaced because there was no other replacement model.
The SR-71 high-altitude reconnaissance aircraft adopts a tailless delta wing with side stripes, a fused vertical double tail and a wing engine nacelle configuration. 93% of the body weight is made of titanium alloy.
There are three upgraded types of SR-71 high-altitude reconnaissance aircraft: Type A is a strategic reconnaissance type, with a total 25 aircraft produced; type B is a training type, with a totall of 2 planes; the aircraft produced; Type C is a training aircraft modified from Type A.
The SR-71 high-altitude reconnaissance aircraft is equipped with two turbojet engines, with a maximum thrust of 11,016 kg per unit and a total thrust of 22,032 kg. The main airborne equipment includes a KA-95B reconnaissance camera, infrared and electronic detection equipment and an AN/APQ-73 synthetic aperture radar.
The aircraft has a length of 32.74 meters, a wingspan of 16.95 meters, a maximum takeoff weight of 77,100 kg, a normal takeoff weight of 63,500 kg and a speed of maximum average flight of 3,392 km/h (M number 3.2). The reconnaissance altitude is 24,000 meters, the practical ceiling is 26,600 meters, the activity radius is 1,930 kilometers, the range is 4,800 kilometers, and the endurance time is 1.5 hours .
The main characteristics of the high altitude reconnaissance aircraftof SR-71 are: advanced reconnaissance equipment, high reliability, fast speed and high altitude. It has never been shot down since its commissioning. However, the SR-71 high-altitude reconnaissance aircraft has long been abandoned. It was initially withdrawn before the Gulf War and was reactivated due to the needs of the war.
Question 4: How far is the lowest cloud layer from the ground? 20 points The lowest cloud:
0 meters above the ground. (Fog is a form of cloud, and we're talking fog here)
The tallest cloud:
Height from the ground is related to latitude.
At low latitudes, it can reach 17,000 to 18,000 meters;
At mid latitudes, it can reach 10,000 to 12,000 meters
At high latitudes, Can reach 8,000 to 9,000 meters.
Note: It is also related to the season. It is higher in summer than thn winter.
Question 5: How high are the clouds relative to the earth? Normally it's 12 kilometers, but I feel like the clouds are actually water vapor condensed into sheets at the top of Changbai. Mountain, The highest point is less than 3,000 meters above sea level, and the highest point of Taishan Mountain is less than 2,000 meters above sea level. They are all shrouded in clouds and fog, so the absolute altitude is not easy to tell. Why don't fighter jets want the SR-71 reconnaissance aircraft to use a turbojet engine is a turbofan engine
The space shuttle flies the highest Apart from it, only high-altitude reconnaissance. The planes fly the highest.

The main characteristics of the reconnaissance aircraft at haute altitude SR-71 are: advanced reconnaissance equipment, high reliability, fast speed and high altitude. It has never been shot down since its commissioning. However, the SR-71 high-altitude reconnaissance aircraft has long been abandoned. It was initially withdrawn before the Gulf War and was reactivated due to the needs of the war.
Turbojet engines are suitable for use on high-altitude, high-speed aviation equipment. There are also high-altitude, high-speed interceptor fighters that use turbojet engines. For example, the former Soviet Union's MiG-25 supersonic high-altitude fighter is powered by the Mikulin-Tumansk Design Bureau's turbojet engine and was once a fighter. speed record of Mach 3.3 with a ceiling record of 37,250 meters. Compared to turbofan engines, turbojets have fuel economyworse, but their high-speed performance is better than that of turbojets, especially high-altitude and high-speed performance. The image below shows a turbojet engine.
Most fighter jets today still use turbojets, and some fighter jets use low bypass ratio turbojets (such as the F-fighter). 22 "Raptor") because first of all, modern turbojet engines can meet the speed requirements of these combat aircraft. Second, due to the poor fuel economy of turbojets, the range is much smaller than that of turbojets with the same fuel load. adaptability, etc., as well as at supersonic speeds. A turbofan engine is more efficient than a pure turbofan engine under certain conditions, which is why these fighters use low-airflow turbofan engines. The photo shows a turbofan engine
