How does the Sidewinder missile work?

The center missile is the first successful air-to-air missile, and has therefore been widely produced, with more than 110,000 for more than 28 countries so far. Sidewinder comes from the United States and is named after a side snake, because the trajectory of the early versions resembled the zigzag of this kind. As with snakes, it is also a finding of heat and can be quite deadly, with more than 270 proven kills since their development in 1956. Typical design, AIM-9L, are 2.85 m (9.4 ft), 1-18 km, depending on weather conditions and bears the load of 9.4 kg. Since 2007, unit costs have been approximately $ 84,000 (USD). When Sidewinder was for the first time in development at the beginning of the 50th year, the aim was to create a reliable and efficient missile with "electronic complexity of the table model and mechanical complexity of the washing machine". This goal has been quickly achieved and its extremely wide acceptance is a testimony to its simplicity and efficiency.

Sidewinder uses an infrared (IR) detector based on lead sulphide. When lead sulphide is exposed to thermal energy, it reduces the electrical resistance of the compound, which is an example of photo system. This reduction in resistance can be measured as associated with action, for example by changing the missile trajectory in the middle of the flight.

In the nose of the side side point, it shows a reflecting mirror forward, reflecting thermal energy from the remote destination to the IR detector. Sidewinder must be roughly directed towards the goal; Otherwise, it will not see anything and just the plow directly forward. If the target is in your SIGHTS, it can measure what angle is the heat source from the direction of its travel. The rocket spacing and radiation are adjusted based on the degree of angle.

Sidewinder also predicts the flight path of the target by means of a mechanically based tracking system, which "remembers" past measurements and projected them forward, causing the rocket to fly through a course called proportional persecution. This allows a rocket "inEst "a goal, just like Quarterback throws a ball where he thinks the receiver will be at a time when the ball arrives rather than throwing it directly from the beginning. This is much more efficient than direct persecution where the missile simply flies in the current direction.
