PL-01
The PL-01 was a Polish light tank concept created by OBRUM with support from BAE Systems, based on the Swedish CV90120-T light tank. The concept vehicle was first unveiled at the International Defence Industry Exhibition in Kielce on 2 September 2013, but the project was scrapped in 2015. Design The layout of the PL-01 is similar to modern standard main battle tanks. The driver is located at the front of the vehicle's hull, with the commander and gunner also located in the hull and the unmanned turret mounted in the rear. In addition, there is a rear compartment in the hull that can accommodate four soldiers. The vehicle chassis is based on that of the Combat Vehicle 90.Remigiusz Wilk, 3 September 2013MSPO 2013: PL-01 Concept vehicle unveiled IHS Jane's 360 The vehicle armor has a modular ceramic-aramid shell, which is designed to provide protection compatible with NATO standard STANAG 4569 Annex A at level 5+ across the front portions of the hull and turret.

Stealth Ground Vehicle
Ground vehicles using stealth technology have come to fruition at various times in history. The Swedish Stridsvagn 103 was designed with a low profile to decrease chances of being detected. The Chieftain SID (Signature Integration Demonstrator) was a first British effort in stealth tank technology. The Challenger 2 features a redesigned hull and turret offering lower radar cross section over its predecessor. More recently, the joint U.S./British Future Scout Cavalry System concept was experimented with and appeared in prototype form before being canceled. Other vehicles, particularly unmanned ground vehicles, may unintentionally have an undetectably low radar signature due to their small size. Various coatings and radar absorbing layers of material are available for combat vehicles. The Armored Gun System program of the 1980s attempted to create a stealth vehicle. One of the competitors, the Stingray light tank later became Thailand's light tank. The M1A2 Abrams was also orig ...

Combat Vehicle 90
The Combat Vehicle 90 (CV90; Sw. ''Stridsfordon'' 90, Strf90) is a family of Swedish tracked combat vehicles designed by Sweden's Defence Materiel Administration (''Försvarets Materielverk'', FMV), Hägglunds and Bofors during the mid-1980s to early 1990s, entering service in Sweden in the mid-1990s. The CV90 platform design has continuously evolved in steps from Mk0 to current MkIV with advances in technology and in response to changing battlefield requirements. The Swedish version of the main infantry fighting vehicle (IFV) is fitted with a turret from Bofors that is equipped with a 40 mm Bofors autocannon. Export versions are fitted with Hägglunds E-series turrets, armed with either a 30 mm Mk44 or a 35 mm Bushmaster autocannon. Developed specifically for the Nordic subarctic climate, the vehicle has very good mobility in snow and wetlands while carrying and supporting eight, later versions six, fully equipped dismounted soldiers. Other variants include Forward ar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Light Tank
A light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently. The fast light tank was a major feature of the pre-World War II army buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks, with the goal of disrupting communications and supply lines. Numerous small tank designs and "tankettes" were developed during this period and known under a variety of names, including the " combat car". Early light tank designs were gene ...

Landmines
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Light Tanks Of Poland
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particl ...

Thermal Imaging
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become ea ...

Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can rang ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Active Protection System
An active protection system is a system designed to actively prevent certain anti-tank weapons from destroying a vehicle. Countermeasures that either conceal the vehicle from, or disrupt the guidance of an incoming guided missile threat are designated soft-kill active protection measures. Countermeasures that physically strike an incoming threat to damage or destroy it and thereby limit its ability to penetrate armor are designated hard-kill active protection measures. Soft-kill measures Soft-kill measures are designed to defeat guided weapons either by concealing the protected vehicle from them (for example, with a smoke screen) or by disrupting their guidance with radiation (for example, with a dazzler). Some systems use laser dazzlers to blind the operator or sensors of semi-automatic command to line of sight (SACLOS) anti-tank guided missiles (ATGMs), such as the JD-3 of the Type 99 tank. Others use powerful infrared emitters to mask the IR tracking flare present on many SACL ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

UKM-2000
The UKM-2000 (''Uniwersalny Karabin Maszynowy'', "Universal Machine Gun") is a 7.62×51mm NATO general-purpose machine gun designed and manufactured by Zakłady Mechaniczne Tarnów in Tarnów, Poland. Development On March 12, 1999, Poland joined the North Atlantic Treaty Organization (NATO). A problem arose with modifying the weapons of the Polish Army to use the standard NATO ammunition. A decision was made to develop a new general-purpose machine gun. The construction was based on the design of the successful PKM machine gun that was previously produced under licence in Poland. To use the common NATO ammunition, the feeding method of the machine gun had to be fundamentally modified. The metallic disintegrating link specifically designed for ammunition belt-fed firearms and rimless 7.62×51mm NATO rounds used by NATO is a push-through design. The UKM machine gun extracts 7.62×51mm NATO rounds from open-M13 links by pushing them forward out of the link directly into the cha ...

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, 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 ...

Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power (physics), power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion (mechanics), torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a Rotating spline, splined joint or prismatic joint.
