that is, the larger lift subsonic missile, its corresponding rise resistance is relatively high, the other low subsonic anti-ship missile flight speed, corresponding to the requirements of the engine is low, the engine's fuel consumption will decline, and therefore modern high subsonic anti-ship missile,hogan interactive, weighing not more than 800 kg, even with low-altitude trajectory , its range can be more than 200 kilometers. But make sure to set the supersonic missile flight index is more difficult, because the supersonic missile in order to reduce the resistance,barbour lyon, to the column select a smaller wing, and as a small area of the wing and lift certainly decreases, all bounced up drag ratio will fall. In general, the super-speed anti-ship missiles Fen lift-drag ratio is about high subsonic anti-ship missiles fifths - one around. When there is a missile flying at high speed,louboutin soldes, the engine needs high speed,louboutin homme pas cher, large fuel consumer expendable,louboutin femme, in general, the supersonic missile fuel consumption ratio is about 2 times subsonic missiles.
a high-altitude trajectory. Altitude ballistic biggest drawback is easy to detect each other. After we all know, modern shipborne air defense system has been developed to phased array radar + vertical launch system,louboutin homme pas cher, which phased array radar detection distance.
the less resistance. Thus,giuseppe zanotti, for supersonic cruise missile,barbour france, if preclude the use of high-altitude cruise altitude dive into the sea-skimming attacks,hogan scarpe, it suffered its cruise segment will be significantly reduced air resistance, corresponding full bomb lift to drag ratio will increase, thereby so that the range is increased. According to information,parajumpers femme, if  super speed anti-ship missiles at low altitude  ? lift-drag ratio is 0.5, then at 10,000 meters altitude above can reach 1.5, so, in other parameters constant,hollister site officiel, the range can be increased by more than 2-fold. For example, Russia will improve 3M80 supersonic anti-ship missile into 3M80VE time, and no missiles and engine improvements,asics online, just modify the flight control system to adjust the trajectory of this dirty aerial patrol, the results put the range from 120 km up to the of 250 km or so. Accordingly,abercrombie france, people see a range of data supersonic missile public generally has two: one is hollow low trajectory.
so that, even if the missile supersonic speed is about three times subsonic missile,oakley pas cher, but considering the other parameters, under the same conditions, the supersonic missile range equivalent to only about half subsonic missiles,hollister site officiel, for example, the weight of 800 kilograms of "Harpoon" missile range at about 150 km altitude, and weighs close to 4000 kg of 3M80 "Sandfly" low altitude range of only 120 kilometers. Data Figure: Tien Kung III anti-missile missileCover a range from cloth out formula can know,mulberry bags outlet, the missile range increases mainly in the following three ways: increasing the lift to drag ratio; improve fuel carrying capacity; reduce fuel consumption. As mentioned above, taking into account the resistance problem supersonic missile,abercrombie & fitch, can not preclude the use of a larger wingspan, so from the aerodynamic point of view, the whole bomb lift to drag ratio can not be improved greatly. However, the missile's flight resistance, mainly from the air - the greater the air density,veste barbour, the greater the resistance; the thinner the air.
