In 1968, the British military vehicle engineering institute (MilitaryVehiclesandEngineeringEstablishment) produced a pistol equipped with a tank-like exterior motorcar; different an in 1971 to odd-volt
British Challenger main battle tank (3 ) Tan-based tanks installed Qiaoba Mu (Chobham) armor, the tank model FV4211. In 1974, Iran to the United Kingdom ordered 707 volts through the modernization of the odd tank MK5P tanks, and proposed to increase the engine power demand, since then the British tanks began FV4030 array of evolution work. Due to time limitations, the two countries coincided that the 1st British creation of 187 with an improved electronic control gear and increased oil storage capability and anti-mine capabilities FV4030 / 1 tank, and then produce 125 installed 882kW (1200 hp) TN37-type engine and gear FV4030 / 2 tank. When Iran penetrate FV4030 / 3 tank program when they resolved to stop buying FV4030 / 2 tank, to array 1 225 FV4030 / 3 tank, but the price mushroomed too quickly and the Iran coup, ordered the contract did not materialize. In September 1978, the British Ministry of Defense and Leeds Arsenal signed a 300 million pounds of 243 Challenger tanks, the production compact. The tank is in the FV4030 / 3 tank based above the development. In December 1982, the British military received the Army Chief of Staff on benefit of Challenger tanks, which marks the Leeds Royal Arsenal make the production of the tank ready. March 1983, Leeds Royal Arsenal to convey the first batch of British Army Challenger tanks. June 1984, the British Army has ordered ample equipment Rhine Army in Germany the fifth group of 64 Challenger tanks. March 1985, the Royal Challenger light cavalry tank with all equipment. In June 1985, the British Army has ordered 18 Challenger tanks. The tanks were in Abu Dhabi (AbuDhabi) and Saudi Arabia had several tests. June 1986, Royal storage of weapons and battle vehicles division (RoyalOrdnanceWeaponsandFightingVehicleDivision) according to the aboriginal tube by the Royal Institute of weapons and equipment research and development (RoyalArmamentResearchandDevelopmentEstabishment) negative current of the tank afterward the chart and design services. July 1986 Vickers Defence Systems to about 11 million pounds to buy the production tanks Leeds Royal Arsenal, and £ 14 million investment in the construction of a fashionable tank fabrication factory, its size and the enterprise in Newcastle above Tyne Armstrong vegetation (ArmstrongWorks) the same. Leeds tank plant Rui production because the British Army Challenger tanks. At the same time, the British Ministry of Defense ordered 100 million pounds Youyi 76 Challenger tanks. Delivery to the end of these tanks, the British Army’s main battle tanks equipped with this type of tank corps a aggregate of 7. British Ministry of Defense ordered the tank volume has more than 400, Challenger tanks, the last batch of fourth quarter 1989 delivery. Structural traits
First, the overall layout of the FV4030 / 3 (Iranian lion 2) tank to the development of the overall layout of Challenger tanks and odd volts Tan Tanke similar to the front of the cockpit in the body, fighting cell In the central body, the rear engine compartment in the body, body armor and turret are accustom Qiaoba Mu. The driver’s seat in the front centre of the body, he has a single flare hatch, hatch tin be raised up and amenable horizontal circulation; have a wide-angle telescope at night tin be replaced with Pilkington (Pilkington) Company passive night vision periscope of PEBadger. Connected with the fighting compartment cockpit, the driver tin enter the fighting compartment through the outlet and depart the tank. Turret in the medium of the body, there are three crew, long in the artillery on the right vehicle, the gunner in the car long before the base, filling in the artillery on the left hand. Drivers and loader have a hatch cover, which is double-leaf architecture, the along backward off, in front of it with a 1 × magnification rotating periscope. Second, the weapon system 1 is the main weapons production Challenger tank’s main weapon is a 120mm L11A5 rifled tank gun style, but afterward models ambition install a XL30 High chamber pressure rifled tank gun. XL30 tank gun from the Nottingham Royal Arsenal (RoyalOrdnanceNottingham) development, previously known for EXP32M1 artillery. The gun barrel is equipped with a thermal jacket, pumping equipment and calibration devices muzzle, barrel with a new ESR iron, breech locking mechanism using the new structure can resist the lofty compartment oppression. Barrel life of 500 rounds of full-charge shells (EPC), to limit the bore dress due to matter fatigue before the end of life will not, end of life is the gun barrel life 10 times. (2) The tank gun ammunition can be fired L15A4 APDS-type, L20A1 style shelling shells, L31-style broken a bombard, L32A5 style broken a adviser bomb, L34-style white phosphorus smoke bombs and newly developed L23A1 APDS-type fin-stabilized . The storage tank has 42 cartridges and 64 bullets location, the position of every ammunition can hold a cilia off shell or two pieces of a bomb or bring smoke cartridges. A typical mongrel storage usage is 20 rounds of ammunition and 44 rounds of APDS broken a bomb or smoke bomb. 3 The tank fire control system uses Marconi Command and Control System (MarconiCommandandControl Systems) company developed improved fire control system (ImprovedFire-ControlSystem-IFCS), the system is the second phase for the odd V Tan Tanke improved design, focus is to improve the tank’s capacity and improve the car a long night fortress (see The main objective of improved fire control system is to significantly depress the target to occupy the shot from the necessitated reaction time, confers artillery target of 3000m and 2000m events fixed target shooting higher first-hit rate. The system tracks the speed of the target class of 30 mils / s, the class near to the track speed is 10-bit / s, curtate turret rotation speed of 0.2 to 480 mils / s, gun lofty and cheap pitch speed of 0.2 to 200 mils / s. The fire control system consists of data processing subsystem (DHSS), target subsystem (TLS), the sensor subsystem and gun control (GCE) and other components. Data processing subsystem including Marconi made 12-12P digital computers and interface drivers control and monitoring devices and drivers / gunner firing knob and other components. Target subsystem, also known for laser ranging tanks aiming devices, laser rangefinder distance range 300-10000m, an precision of ± 10m. Sensor subsystem can determine the manoeuvre of the target angular speed, gun trunnion slope angle, air speed, atmosphere oppression and temperature. Gun control apparatus controlled by the computer. Drivers have a 1 × exaggeration sight of 37 day and Frank? Princeton (RankPullin) the company’s image intensifier night vision sight. Early models of the Challenger tank with Frank? Princeton’s 5 × exaggeration of 37, the night sight (SS120), drivers can use the mirror for night surveillance, target arrest and target. In counting, in the car on long fortress likewise has 9 periscopes, providing a long week for the car, for the capacity. 37 interchangeable sight and the British Ministry of Defense rewarded the Barr Stroud (BarrandStroud) the company developed thermal imaging gun sight with Monitor (likewise phoned thermal imaging reconnaissance and firing sight TOGS) a transitional reach. In order to install the system, has been re-design of the turret. Armored turret on the right within a single shell thermal imager will be a long and gunner for the vehicle to provide general observation of the output signal, or use as a gun sight. The tank’s thermal imaging sight observation and firing of the second batch of thermal imaging prevalent modules delivered in late 1983 by Frank? Taylor? Hobson (RankTaylorHobson) provides infrared search module, Marconi Avionics Engineering (MarconiAvionics) provides computing electronic devices. New production and early production of Challenger tanks have been installed this sight. In April 1987, the British Ministry of Defense announced that the last batch of peppery shot sight as inspected with the production contract is around £ 35 million, which is odd for the challenger and the third order V Tan Tanke sight, Baltimore and Manchester Lauder Company and A Weimo (Avimo)’s half of the production order amount. Barr and Straw Line sight provided that the total prerequisite of 85% of the total Department of Defense. Gunner has a periscope-type 10 MK1 tank laser rangefinder sight, there are two varieties of 1 × and 10 × magnification, field of view is 8.5 °; there is an emergency 87 mounted on the periscope sight crustacean body, but can be quickly and with the artillery found alignment, with the odd V Tan Tanke ordinary telescopes, the mirror is from the altitude of the armored turret hatch upon the projection, the front turret armor to dodge abuse to the integrity of . 4 patronizing arms assisting arms of a collateral with the main weapon installed 7.62mmL8A2 machine guns and a long tower installed in the car on the 7.62mmL37A2 type machine gun. Third, the propulsion system power transmission components including engines, transmissions and cooling equipment, re-5.49t. In field conditions, with the Royal electro-mechanical engineering (REME) of a light-assisted removal equipment can be replaced among 45min whole powertrain components. 1 engine to the tank using a Perkins engine (PerkinsEngines) produced Tat (Condor) 12V-1200 model turbo diesel engine, when in 2300r/min power 882kW (1200 hp). The engine has two turbochargers, cylinder power up to 73.5kW (100 hp), the use of electronic control devices. 2 gear engine matched with Tat is TN37-type transmission apparatus, the appliance consists of David? Brown Gear Industries (DavidBrownGearIndustries) developed and produced by the torque converter, planetary-type variable speed mechanical steering and STN37 combination. Torque converter with lockup clutch, the Borg? Live sodium (BorgWarner) company; speed change machinery with 4 forward and three reverse; civil hydraulic steering (CommercialHydraulics) developed by the company Lucas (Lucas)’s CAV drive control system by monitoring the speed of the output shaft speed and accelerator drive position, automatically elect the proper gear, the engine is always in the best condition. Wet multi-plate friction brake friction control expropriation is made of steel coated with copper, in the hydraulic fuel lubrication and cooling by work. In adding, the car comes with parking and emergency use of the handbook stop. 3 cooling unit cooling device consists of Marston (Marston) produced, using Aia Sike Luo fan? Howden (AirLogLimited) jointly developed by Vickers Defence Systems Division’s product, its features can greatly increase the loading cycle stroke (total stroke of 450mm) and significantly reduced body vibration, and do not account for inner space. There are 6 on each side of the body brim hanging plastic aluminum cycle load wheel, four prop pulley, a front wheel and an induction of vigorous rear wheel. New tracks can be tracked with the odd V Tan Tanke commute. Fourth, the protection system 1 of the tank body armor and armored turret secondhand Qiaoba Mu is thought protective since World War II tank design and made the maximum remarkable accomplishments, and other weight compared to steel armor, greatly improved anti-shaped charge and a broken melodrama ability, but tiny increase in size and weight, case in point, Tan Challenger Tankebiqi V-type MK5 merely weight 7t. 2 smoke grenade launchers on each side of the front of the turret by the installation of a group of 5 transmitters to send electric shocks into the smoke launchers, each launcher can cover 100 ° of the space. Expected that this device will be replaced by the Royal Arsenal development of apparent light and infrared light smoke barrier system (VIRSS). 3 measures to prevent secondary effects of all the charge cached in the turret seat are emulating a special receptacle, the liquid inside the receptacle walls to reduce fire peril. In the latter part of the production models, loading containers also increases with armored protection floor.

Plessey Aerospace (Plessey Aerospace) developed by the company for the new tank auxiliary power unit (APU) is installed on the seventh task of the Challenger Challenger tanks and armored salvage vehicle repair. The device is driven by a Perkins diesel engine company, fuel injection cooled brushless generator may publish a 350A current, auxiliary power unit with H30-type exchange. Plessey Aerospace has also developed a fuel injection by the main engine-driven cooling of the 500A power system, the tank has been tested successfully on and ready to fix armored liberate vehicle in the challenger trials. Blair (Blair) company’s new steel double-pin track, tests are being arranged to replace the current use of single pin type track. New track with exchangeable rubber ear pads and sell pouches can reduce rolling resistance and longer track life. Weapon system improvements will be completed, including improved gun control system, fire control system, installation of thermal imaging devices and power-driven observation tower. 2. Challenger 2 tanks in the tank is replaced by the British Army more than 500 odd volts Tan Tanke of the championship one of the adoptions developed by the Vickers Defence Systems. The use of Challenger tanks tank chassis, equipped with a protection coerce to improve the new turret and a new fire control system. Turret can be installed on the Royal Arsenal development of new CHARM 120mm rifled tank gun can also be installed Rheinmetall Germany (Rheinmetall) The 120mm smoothbore tank gun. 3. Driver exercising tanks in February 1988 the British Army with 18 million pounds to the Vickers Defense Systems exercising ordered 17 Challenger tanks, will be delivered in 1990. This is basically a tank turret into a small compartment to the Challenger main battle tank, the hut can take coaches and students, and a body weight of iron, so that performance is closer to the Challenger main battle tank. The tank system for the Royal Armoured Forces and the Royal Academy of electro-mechanical engineering training pilots and maintenance personnel. 4. Challenger Armoured Repair Rescue (CRARRV) The rescue vehicle is Vickers Defence Systems developed for the British Army, the first production 30. 6 pre-production car in the first one made in August 1987, completed by the end of 1988, Vickers Defence Systems, Inc. and by the British Army after the test fashion production. The car’s standard equipment hydraulic winch, neutral auxiliary winch, hydraulic cranes and front blade installed. See 5. Challenger and antiaircraft artillery turret sharpshooter June 1985 Marconi Command and Control Systems sharpshooter (Marksman) twin 35mm antiaircraft gun turret mounted on the chassis Johnson Chiu Lun Tanke the shooting test.
