Recently, the discussion of domestic zhi20 helicopter has been heated. After all, the use frequency of helicopter in modern battlefield is really too high. Whether it is all kinds of air sudden landing or resource transportation, or armed reconnaissance and fire attack, it is inseparable from helicopter. If we say the era of mechanized vehicles in World War II, the modern battlefield is the era of large-scale application of helicopters. Of course, in this conflict, we also see the vulnerability of helicopters under modern air defense fires, which are easy to be hit by various systematic air defense fires. For this problem, the domestic zhi20 has also made great efforts in active defense. Recently, we have seen that the zhi20 fuselage has added new equipment.
From the picture, the zhi20 this time should be an army model. From the appearance, the model is equipped with a raised square device above the landing gear. According to military fans, it should be some kind of jammer, which can play an active defense role, improve its survivability, or; Poisonous sting ” This kind of infrared guided individual air defense weapon plays a good defensive role.
In fact, jammers are also a kind of electronic warfare. For example, modern armed helicopters are generally equipped with active infrared directional jammers, which can irradiate the incoming infrared guidance weapons, interfere with their infrared guidance heads and make them “ Blinding ” Thus, the target cannot be locked correctly. This also allows armed helicopters to actively defend against attacks, rather than passively releasing decoy bombs and other false targets, or simply strengthening the armor level to resist hard.
So zhi20 may be this type of jammer installed this time, but it is still uncertain what kind of guidance weapons it is for. At present, long-range strike weapons have many ways, such as infrared guidance, television guidance, laser guidance, millimeter wave guidance, etc., and the ways of active anti-jamming for different weapons are also different. So many helicopters now appear on their bodies “ Big bag and small bag ” A large number of prominent external devices, all because the current threat of air defense weapons to helicopters is too great, so we have to do it.
In fact, compared with zhi20, Wuzhi 10 has also added a lot of active defense devices recently. Of course, as a general-purpose transport helicopter, zhi20 obviously will not be in the same bad environment as wuzhi10, so there is much less demand for active defense. In contrast, we see more active defense and self-defense devices on the shipborne zhi20 antisubmarine, such as various jammers and maws system, which is commonly known as the missile approach warning system. It can detect all kinds of incoming weapons around and give warning to the greatest extent, and arrange the airborne active defense device to respond at the same time, which is equivalent to the early warning radar of the helicopter.
Many military fans speculate that the future zhi20 transport may also be equipped with warning devices such as maws. After all, from the perspective of this conflict, although one party has absolute air control, the other party can still carry out individual air defense attack by ambushing on the supply line and dispersing to the rear of the enemy, which also has a great impact on some transport helicopters. Then it is necessary to install various comprehensive alarm devices such as infrared alarm, ultraviolet alarm and laser alarm.
At present, active maws and passive are widely developed in western countries, which can be simply understood as active radar and passive radar. Generally, the active uses Doppler radar to work in L-band, while the passive uses computer algorithm. Both have their own advantages and disadvantages. For the 10 ton platform like zhi20, it is more economical to choose passive algorithm, and it is less difficult to improve, but it can effectively improve its survivability.
Overall, the installation of new active defense equipment for zhi20 can be seen as a beginning, indicating that after its main performance meets the requirements, zhi20 will further improve its electronic countermeasure capability in the future to improve its survivability. This also puts forward a direction for the future upgrading of zhi20. After all, in the real battlefield, the survivability of equipment is even more important than the outstanding performance. If we can get a lower exchange, we can really save ourselves and destroy the enemy.
