Raad 2
''Raad''-2 ( Persian:رعد-۲, means Thunder-2) is an Iranian self-propelled howitzer. Development In early September 1997, it was reported that Iran had successfully tested a locally built rapid fire mobile field gun known as ''Raad''-2 (Thunder-2). It uses a turret that has a similar layout to the M109A1 155mm/39-cal self-propelled howitzer. The Iranian Defense Industries Organization claimed that the 155 mm HM44 howitzer manufactured by the Hadid facility of the Iranian Defense Industries Organization had a high firing rate and accuracy. The gun's range was reported as , and it also includes features such as a laser range-finder and a semi-automatic loading system. The gun looks exactly like 155mm/39-cal M185 gun from M109A1 and is fitted with a double baffle muzzle brake, fume extractor, screw breech mechanism, hydro-pneumatic recuperator and a hydraulic recoil brake. DIO says that the barrel life is around 5,000 rounds. The vehicle uses a chassis based on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Howitzer
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/ missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns (tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured wh ...

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.
