EuroSpike GmbH
Spike (Hebrew: ספייק) is an Israeli fire-and-forget anti-tank guided missile and anti-personnel missile with a tandem-charge high-explosive anti-tank (HEAT) warhead. , it is in its fourth generation. It was developed and designed by the Israeli company Rafael Advanced Defense Systems. It is available in man-portable, vehicle-launched, and helicopter-launched variants. The missile can engage and destroy targets within the line-of-sight of the launcher ("fire-and-forget"), and some variants can make a top attack through a "fire, observe and update" method (essentially lock-on after launch); the operator tracking the target, or switching to another target, optically through the trailing fiber-optic wire (or RF link in the case of the vehicle-mounted, long-range NLOS variant) while the missile is climbing to altitude after launch. This is similar to the lofted trajectory flight profile of the US FGM-148 Javelin. Design Spike is a fire-and-forget missile with lock-on before ...

Mock-up
In manufacturing and design, a mockup, or mock-up, is a scale model, scale or physical model, full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup may be a ''prototype'' if it provides at least part of the functionality of a system and enables testing of a design. Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". Applications Mockups are used as design tools virtually everywhere a new product is designed. Mockups are used in the automotive device industry as part of the product development process, where dimensions, overall impression, and shapes are tested in a wind tunnel experiment. They can also be used to test consumer reaction. Systems engineering Mockups, website wirefram ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem-charge
A tandem-charge or dual-charge weapon is an explosive device or projectile that has two or more stages of detonation, assisting it to penetrate either reactive armour on an armoured vehicle or strong structures. Anti-tank Tandem charges are effective against reactive armour, which is designed to protect an armoured vehicle (mostly tanks) against anti-tank munitions. The first stage of the weapon is typically a weak charge that either pierces the reactive armour of the target without detonating it, leaving a channel through the reactive armour so that the second warhead may pass unimpeded, or simply detonates the armour, causing the timing of the counter-explosion to fail. The second detonation from the same projectile (which defines it as a tandem charge) attacks the same location as the first detonation where the reactive armour has been compromised. Since the regular armour plating is often the only defence remaining, the main charge (second detonation) has an increased li ...

Lock-on After Launch
Lock-on after launch (LOAL) is an ability of missile systems to lock-on to a target after being launched from a carrier vehicle. The term is normally used in reference to airborne weapons, especially air-to-air missiles. LOAL is an important part of modern weapon systems as it allows a weapon to be carried internally to increase stealth and then acquire a target once it has left a launching aircraft. LOAL systems normally rely on cuing from a helmet mounted sight or onboard sensors like radar or forward-looking infrared (FLIR), and use a simple strapdown inertial guidance system to know where to look after launch. Examples of LOAL weapons include the Advanced Short Range Air-to-Air Missile (ASRAAM) and later versions of the AGM-114 Hellfire anti-tank missile An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a Missile guidance, guided missile primarily designed to hit and destroy Armoured fighting vehicle, hea ...

Top Attack
Plunging fire is a form of indirect fire, where gunfire is fired at a trajectory to make it fall on its target from above. It is normal at the high trajectories used to attain long range, and can be used deliberately to attack a target not susceptible to direct or grazing fire due to not being in direct line of sight. In naval warfare, plunging shellfire was theoretically capable of penetrating an enemy ship's thinner deck armor rather than firing directly at a warship's heavily armored side. Plunging fire in terrestrial warfare allows attacking a target not in direct line of sight, for example over the brow of a hill engaging in a reverse slope defence. Artillery weapons such as howitzers and mortars are designed for this purpose. Machine guns and belt-fed grenade launchers may also use plunging fire. A top attack weapon is designed to attack armoured vehicles from above as a form of plunging fire, as the armour is usually thinnest on the top of the vehicle. Ideally, it will p ...

High-explosive Anti-tank
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity explosively formed penetrator (EFP) jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The EFPs jet effect is purely kinetic in nature; the round has no explosive or incendiary effect on the target. Because they rely on the kinetic energy of the EFP jet for their penetration performance, HEAT warheads do not have to be delivered with high velocity, as an armor-piercing round does. Thus they generate less recoil. The performance of HEAT weapons has nothing to do with thermal effects, with HEAT being simply an acronym. History HEAT warheads were developed during World War II, from extensive research and development into shaped charge warheads. Shaped char ...

Anti-personnel Weapon
An anti-personnel weapon is a weapon primarily used to maim or kill infantry and other personnel not behind Armour, armor, as opposed to attacking structures or vehicles, or hunting Game (hunting), game. The development of defensive fortification and combat vehicles gave rise to weapons designed specifically to attack them, and thus a need to distinguish between those systems and ones intended to attack people. For instance, an anti-personnel land mine, landmine will explode into small and sharp splinters that tear flesh but have little effect on metal surfaces, while anti-tank mines have considerably different design, using much more explosive power to effect damage to armored fighting vehicles, or use explosively formed penetrators to punch through armor plating. Many modern weapons systems can be employed in different roles. For example, a tank gun, tank's main gun can fire armor-piercing ammunition in the anti-tank role, high-explosive ammunition in the anti-structure role and ...

Anti-tank Guided Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and gave lig ...

Fire-and-forget
Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks. Generally, information about the target is programmed into the missile just prior to launch. This can include coordinates, radar measurements (including velocity), or an infrared image of the target. After it is fired, the missile guides itself by some combination of gyroscopes and accelerometers, GPS, onboard active radar homing, and infrared homing optics. Some systems offer the option of either continued input from the launch platform or fire-and-forget. Fire-and-forget missiles can be vulnerable ...

Modern Hebrew
Modern Hebrew ( he, עברית חדשה, ''ʿivrít ḥadašá ', , '' lit.'' "Modern Hebrew" or "New Hebrew"), also known as Israeli Hebrew or Israeli, and generally referred to by speakers simply as Hebrew ( ), is the standard form of the Hebrew language spoken today. Spoken in ancient times, Ancient Hebrew, a member of the Canaanite branch of the Semitic language family, was supplanted as the Jewish vernacular by the western dialect of Aramaic beginning in the third century BCE, though it continued to be used as a liturgical and literary language. It was revived as a spoken language in the 19th and 20th centuries and is the official language of Israel. Of the Canaanite languages, Modern Hebrew is the only language spoken today. Modern Hebrew is spoken by about nine million people, counting native, fluent and non-fluent speakers. Most speakers are citizens of Israel: about five million are Israelis who speak Modern Hebrew as their native language, 1.5 million are immigra ...

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital cameras, act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Homing
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares beh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
