  2. RS-82 (rocket family) - Wikipedia

    en.wikipedia.org/wiki/RS-82_(rocket_family)

    RS-82. RS-82 officially entered service in 1937 and RS-132 in 1938. [5] The RS-82 missiles were carried by Polikarpov I-15, I-16 and I-153 fighter planes, the Polikarpov R-5 reconnaissance plane and the Ilyushin Il-2 close air support plane, while the heavier RS-132 missiles could be carried by bombers.

  3. Autogenous pressurization - Wikipedia

    en.wikipedia.org/wiki/Autogenous_pressurization

    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.

  4. Propellant tank - Wikipedia

    en.wikipedia.org/wiki/Propellant_tank

    Rocket propellant tanks are of many shapes but the optimum shape of a tank is spherical, because for given volume it results in a tank with least weight. Normally, propellant in the tank is stored at a pressure of about 1-4 bar, if the system uses turbopump to deliver high pressure to the combustion chamber.

  5. Pressure-fed engine - Wikipedia

    en.wikipedia.org/wiki/Pressure-fed_engine

    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 ...

  6. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V

  7. Steam accumulator - Wikipedia

    en.wikipedia.org/wiki/Steam_accumulator

    Steam can be drawn off as required, either for driving a steam turbine or for process purposes (e.g. in chemical engineering), by opening a steam valve on top of the drum. . The pressure in the drum will fall but the reduced pressure causes more water to boil and the accumulator can go on supplying steam (while gradually reducing pressure and temperature) for some time before it has to be re-char

  8. WZ-132 light tank - Wikipedia

    en.wikipedia.org/wiki/WZ-132_Light_Tank

    WZ-132 light tank (simplified Chinese: WZ-132轻型坦克; traditional Chinese: WZ-132輕型坦克) was a Chinese light tank which was developed between the 1960s and 1970s. Its development lasted for more than ten years before it was set aside, ultimately proving too technical to be brought into production.

  9. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
