Briz-M
The Briz-M ((ロシア語:Бриз-М) meaning ''Breeze-M'') and Briz-KM are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M rocket or Rokot, one of Russia's smaller launchers.
== Characteristics ==
The Briz-M upper stage is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit.〔(【引用サイトリンク】title=Breeze M upper stage )〕 The main engine can be restarted 8 times in flight and allows precision placement of the spacecraft into orbit.〔(Proton Launch System Mission Planner's Guide ) International Launch Services. Retrieved on 2008-03-23〕 Orbital lifetime of the Briz-M is limited by available onboard battery power and is currently 24 hours.〔 The total time of the standard Proton/Briz-M mission profile from lift-off to spacecraft separation is approximately 9.3 hours.〔 A Proton launch vehicle with a Briz-M upper stage can also inject payloads to Earth escape trajectories.〔
One of system's design goals has been to keep overall dimensions as small as possible. Briz-M takes much less space on board the launch vehicle compared to its predecessor, the Block D upper stage, leaving freed volume for the cargo.〔http://www.russianspaceweb.com/proton.html〕 A Proton with a Briz-M can place a 4,385 kg satellite, such as an A2100AX, into a target orbit with an apogee of 35,786 km, a perigee of 7,030 km, and an inclination of 17.3°.〔(【引用サイトリンク】 orbit.jpg )〕〔(【引用サイトリンク】 Breeze-M Powered Flight )〕 Maximum lift capability of the Briz-M stage is 5,645 kg to geosynchronous transfer orbit with a 1,500 m/s residual velocity to GSO.〔(Proton/Breeze-M ) International Launch Services, retrieved on 2009-03-23〕 A tandem launch of multiple spacecraft is also supported, with the ability to inject the spacecraft into different orbits.〔
Briz-M is a twin upper stage consisting of a core module (using Briz-KM as the baseline) and a jettisonable add-on doughnut tank surrounding the core.〔 It is powered by a pump-fed gimballed main engine, the 14D30.〔
