Helicopters are not afraid of grenades

10.05.2012

RAFAEL has presented an original system for active protection of helicopters from various guided and unguided projectiles, such as shots from anti-tank grenade launchers.

RAFAEL specialists have already created a similar tank active protection system called Trophy. She successfully operates in the Israeli army and has repeatedly saved Merkava tanks from being hit by guided anti-tank missiles.

At present, helicopters are quite reliably protected from MANPADS missiles with an infrared homing head (IR seeker): high-speed systems based on powerful infrared lasers effectively blind the infrared seeker and divert missiles to the side. However, in low-intensity conflicts, helicopters are often subjected to rocket-propelled grenades and anti-tank missiles. Despite the fact that these weapons were not originally designed to deal with air targets, helicopters are an excellent target for him, especially in hover mode and during takeoff / landing. At the same time, unlike MANPADS missiles, RPG shots are unguided and it is impossible to "deceive" them with the help of interference.

The new RAFAEL active protection system intercepts a flying grenade or missiles with the help of a fired anti-projectile.

In a test conducted in September 2011, the new system, called Fliker, successfully intercepted an RPG grenade at a safe distance. As planned by the developers, the counter-projectile shot down the grenade without detonating its warhead, which reduces the risk of collateral damage and destruction of the protected object.

The Fliker is the helicopter's last line of defense in addition to existing launch warning systems and laser countermeasures for infrared seeker. In the event that a rocket or grenade nevertheless breaks through to the helicopter, Fliker will work and the threat will be neutralized.

The launcher, developed by Manor, consists of high-speed electric drives and pyrotechnic charges capable of directing the counter-projectile towards the threat with high accuracy. The warhead of the anti-projectile is activated by the latest optical fuse developed by RAFAEL.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
