The Proton M's improvements included lower stage modifications to reduce structural mass, increase thrust, and fully use propellants. Generally a Briz-M ( Russian : Бриз meaning Breeze ) storable propellant upper stage is used instead of the Blok D or Blok DM stage, removing the need for multiple fuel supplies and oxygen top-off due to ...
The Proton-M, (Протон-М) ... The RD-0211 is a version of the RD-0210 modified with a heat exchanger used to pressurize the propellant tanks. The second stage ...
Rocket propellant is used as reaction mass ejected from a rocket engine to produce ... N 2 O 4 /UDMH is the main fuel for the Proton rocket, older Long March rockets ...
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
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.
St. Marks Powder is a subsidiary of General Dynamics Ordnance and Tactical Systems manufacturing ball propellant [1] in Crawfordville, Florida. St. Marks makes about 6,000 tons per year, [2] making it the world's largest producer of propellant. [3] The company is a member of the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI).

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 ...
This is a list of launches made by the Proton rocket between 1965 and 1969. All launches were conducted from the Baikonur Cosmodrome.The list includes the first five launches, which were conducted under the designations UR-500 and UR-500K, before the selection of the name Proton.
