The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
Its maximum effective range is 3,000 m (3,300 yd). According to Jane's, the M829 is capable of penetrating 540 mm (21 in) of RHA steel armor at up to a 2,000 m (2,200 yd) range. [3] The original M829 is no longer in production and has been succeeded by the M829A1, M829A2, and M829A3. The corresponding training round is the M865, costing $1,121. [2]
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Mariotte's bottle is a device that delivers a constant rate of flow from closed bottles or tanks. It is named after French physicist Edme Mariotte (1620-1684). A picture of a bottle with a gas inlet is shown in the works of Mariotte, [ 1 ] but this construction was made to show the effect of outside pressure on mercury level inside the bottle.
Cutaway of Space Shuttle external tank. Autogenous pressurization is the use of self-generated gaseous propellant to pressurize liquid propellant in rockets.Traditional liquid-propellant rockets have been most often pressurized with other gases, such as helium, which necessitates carrying the pressurant tanks along with the plumbing and control system to use it.
In May 2014, three months before DARPA started the GXV-T program, the Tank Automotive Research, Development and Engineering Center (TARDEC), which provides the technological backbone for all Army and U.S. Marine Corps ground vehicles, issued a report called "GXV Operational Vignettes" which included two dozen pages of sketches of next-generation ground combat vehicle designs.
Pressure-fed rocket cycle. Propellant tanks are pressurized to directly supply fuel and oxidizer to the engine, eliminating the need for turbopumps. The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To ...
A VRU works by compressing the flash gas that is produced in storage tanks and other units to be put into a pipeline. A basic VRU is made up of a scrubber, compressor, and a switch. Once the pressure in the tank reaches the set-point, the switch kicks on the compressor and sends the vapor to a scrubber where the liquid portion is separated out ...
