Chinese solar powered drone ascended into space

47
According to the news agency "UNIAN, The Chinese solar-powered drone has reached near space. Previously, a similar achievement could be made only by the United States and Britain.



UAV "Tsayhun" ("Rainbow") was developed by the Chinese Academy of Aerospace Sciences and Technology. As indicated, the drone can be used both for military and civilian purposes, in particular to warn of natural disasters, to monitor the marine areas, used in rescue and anti-terrorist operations.



The first test flight took place on August 31 2015 of the year in Gansu Province at an altitude of 20 km. . According to the media, the wingspan of the vehicle reaches 20 m, the payload is 900 kg, the take-off weight is up to 3 t.

    CH-4B: Chinese “Rainbow” crowds out American “Predators” China’s shock drones are gaining popularity in the Middle East. So, CH-4 B are in service with Iraqi aviation. So, in October 2015, the Iraqi Ministry of Defense released a video that captures the launch of the CH-4 B from Al Kut airbase, located southeast of the Iraqi capital Baghdad.

      It is also known that such devices were exported to two other Middle Eastern countries - Egypt and Saudi Arabia, which acquired them to meet urgent needs as part of a military operation in Yemen, since there were delays in the purchase of comparable systems from the United States. UAVs of the CH-4 series (Cai Hong 4 - "Rainbow-4") are considered to be some kind of analogues of the American UAVs MQ-1 Predator. According to the South China Morning Post, the wing span of the CH-4A is 18 meters, weight is 1260 kilograms, flight duration is about 30 hours, and range is 3500 kilometers. The CH-4B version can be in the air for 14 hours, taking into account the missile and bomb load of up to 345 kilograms. Laser-guided air-to-surface AR-1 guided missiles and small-caliber high-precision FT-5 bombs can be mounted on this modification.

            I think the Americans do not have extra parts, but the Chinese sifted all the sand of Iraq, the specialists went through all the mountains of Afghanistan and a bunch of other countries, in search of downed and emergency American UAVs. And where they couldn’t go straight, I think they just bought it, but for serious money, such as Iran.

          If I hadn’t skipped school (and it doesn’t matter when I graduated), I would have known that the flight time at the speed of low-speed propeller-driven aircraft can be many tens of hours, even though the battery capacity is already quite high today with low weight (if we talk about LipO batteries). For the Pimer, the 2S1P 5000mAh 7.4v battery weighs only 200g. it’s not difficult to calculate a pack for the required voltage and capacity when weighted.
          and this despite the fact that modern electric motors are extremely economical, but at the same time very productive with an efficiency of 90% ... And solar panels have incredibly high efficiency.
          From everything, it should become clear that on a solar battery, if you wish, you can fly around the earth. It all depends on the goal and of course the payload.
          Accordingly, reaching the target at night is just a matter of navigation. Duration of work is a matter of ABA capacity and the number of maneuvers over a target, which is unlikely to be very different from hovering in a circle.

    Of course, I wildly apologize, but since when 20km is near space.
    Near space is from the Karman line (from about 100 km), because at this altitude, so that the aircraft relies on the atmosphere (aerodynamic lift), it is necessary to move at least at the first cosmic speed (7,9 km / s or about 27 M, taking into account altitude) hi

                For this, systems like S-500 are created in Russia and each state reserves the right to shoot any objects over its territory, regardless of the height of the object’s flight, yes, and for reference:
                VZK RF, Article 1. Sovereignty in relation to the airspace of the Russian Federation
                1. The Russian Federation has complete and exclusive sovereignty over the airspace of the Russian Federation.
                2. The airspace of the Russian Federation means airspace over the territory of the Russian Federation, including airspace over inland waters and the territorial sea.
                Additionally, it follows from the Decree of the Government of the Russian Federation of March 11, 2010 N 138 Moscow “On Approving the Federal Rules for the Use of the Airspace of the Russian Federation” that the airspace of the Russian Federation is divided into lower and upper airspace:
                The boundary of the lower and upper airspace is a level of 8100 m, i.e. from 0 to 8099 - the lower;
                8100 - to infinity (not limited by law) - the top.

            So space or not space? And then 20km near space, and 90-120km the border between the atmosphere and space. That’s how it goes with us? space, then not space (border), then space?

      Atmosphere and near-Earth outer space

      Sea level - 101,3 kPa (1 atm .; 760 mm Hg atmospheric pressure), density of the medium 2,7 · 1019 molecules per cm³.
      0,5 km - up to this height lives 80% of the human population of the world.
      2 km - up to this height lives 99% of the world's population.
      2 — 3 km is the beginning of the manifestation of ailments (mountain sickness) in non-acclimatized people.
      4,7 km - MFA requires additional oxygen supply for pilots and passengers.
      5,0 km - 50% of atmospheric pressure at sea level.
      5,3 km - half of the total mass of the atmosphere lies below this height (slightly below the top of Mount Elbrus).
      6 km - the boundary of the permanent habitat of man, the boundary of terrestrial life in the mountains.
      6,6 km - the highest located stone building (Mount Luluillaciaco, South America).
      7 km - the limit of human adaptability to a long stay in the mountains.
      8,2 km - the border of death without an oxygen mask: even a healthy and trained person can lose consciousness and die at any time.
      8,848 km - the highest point of the Earth Mount Everest - the limit of accessibility on foot.
      9 km - the limit of adaptability to short-term breathing of atmospheric air.
      12 km - breathing air is equivalent to being in space (the same time of loss of consciousness ~ 10 — 20 s); the limit of short-term breathing with pure oxygen without additional pressure; ceiling of subsonic passenger liners.
      15 km - breathing pure oxygen is equivalent to being in space.
      16 km - when in a tall suit in the cockpit, additional pressure is needed. 10% of the atmosphere is left above your head.
      10 — 18 km is the boundary between the troposphere and stratosphere at different latitudes (tropopause). This is also the boundary of the rise of ordinary clouds, then rarefied and dry air extends.
      18,9 — 19,35 - Armstrong line - the beginning of space for the human body - boiling water at the temperature of the human body. Internal body fluids at this height still do not boil, because the body generates enough internal pressure to prevent this effect, but saliva and tears may begin to boil with the formation of foam, swell eyes.
      19 km - the brightness of the dark purple sky at the zenith 5% of the brightness of the clear blue sky at sea level (74,3 — 75 candles versus 1500 candles per m²), the brightest stars and planets can be seen during the day.
      20 km - the intensity of the primary cosmic radiation begins to prevail over the secondary (born in the atmosphere).
      20 km - the ceiling of hot air balloons (hot air balloons) (19 811 m).
      20 — 22 km is the upper boundary of the biosphere: the limit of the rise in the atmosphere of living spores and bacteria by air currents.
      20 — 25 km — the brightness of the sky during the day is 20 — 40 times less than the brightness at sea level, both in the center of the total solar eclipse strip and at dusk when the Sun is below the horizon by 9 — 10 degrees and stars are visible up to the 2 magnitude.
      25 km - during the day you can navigate through the bright stars.
      25 — 26 km — maximum steady-state flight altitude of existing jet aircraft (practical ceiling).
      15 — 30 km is the ozone layer at different latitudes.
      34,668 km is the official altitude record for a balloon (stratostat) operated by two stratonauts (Project Strato Lab, 1961).
      35 km is the beginning of space for water or a triple point of water: at this height, water boils at 0 ° C, and above it cannot be in liquid form.
      37,65 km - the height record of existing turbojet aircraft (Mig-25, dynamic ceiling).
      38,48 km (52 000 steps) is the upper boundary of the atmosphere in the 11 century: the first scientific determination of the height of the atmosphere by the duration of twilight (Arabic scientist Algazen, 965 — 1039 years).
      39 km is the record for the height of a stratospheric balloon controlled by one person (F. Baumgartner, 2012).
      45 km is the theoretical limit for a ramjet.
      48 km - the atmosphere does not weaken the ultraviolet rays of the Sun.
      50 km is the boundary between the stratosphere and the mesosphere (stratopause).
      51,694 km - the last manned altitude record in the pre-cosmic era (Joseph Walker on the X-15 rocket plane, 30 on March 1961)
      51,82 km - altitude record for gas unmanned aerostat.
      55 km - the atmosphere does not affect cosmic radiation.
      40 — 80 km — the maximum ionization of air (the conversion of air into plasma) from friction against the body of the descent vehicle when it enters the atmosphere at the first space velocity.
      70 km is the upper boundary of the atmosphere in 1714 according to the calculation of Edmund Halley based on data from climbers, Boyle's law and observations of meteors.
      80 km - boundary between the mesosphere and the thermosphere (mesopause): the height of the silvery clouds.
      80,45 km (50 miles) is the official height of the space border in the United States.
      100 km is the official international border between the atmosphere and space - the Karman line defining the boundary between aeronautics and space. Aerodynamic surfaces (wings) starting from this altitude do not make sense, since the flight speed to create lift becomes higher than the first cosmic velocity and the atmospheric aircraft turns into a space satellite. The density of the medium at this height is 12 trillion molecules per 1 dm³

    LENOVO is IBM, well, for starters. Whom, and in what place is she catching up? Gnusmus has never been on the laptop market, for example, a leader. And the technologies of ALL manufacturers are the same. x86 processors are Intel and AMD, intel, amd, nVideo, VIA, etc. chipsets, AMD and Intel vidos. So are the phones. Manufacturers of RISC processors are well known, memory, too, the matrix can be put more expensive / cheaper.

    The last 15 years at international mathematics olympiads, Koreans and Chinese began to take first places.

    Another of the cohort of liars, hiding behind nicknames, flags, mimicking the supporters of the USSR and lovers of Stalin. But in fact, engaged in the blackening of Russia.
    Liar! Read the truth!

    Unofficial credit for 15 years:
    RUS 7 8 4 4 4 4 2 3 2 1 2 3 3 5 2
    CHN 3 2 1 1 2 1 1 1 1 2 1 1 1 2 1
    KOR 2 3 7 2 1 13 4 4 4 3 3 5 12 6 6

    The situation is somewhat different, isn't it?
    China has now trained teams to solve the problems presented at the IMO, they have a rating higher than all countries in the world. However, it is Russia that immediately follows him, given that the United States ranked 2nd in the overall ranking took part in a significantly larger number of competitions (25/42!)
    The Republic of Korea ranks 7th in the overall ranking.

    Do not do lies and slander.
