The Briz-K, Briz-KM and Briz-M (Russian: Бриз-К, КM and M meaning Breeze-K, KM and M) are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M and Angara A5.

Briz-M: Russia's workhorse space tug. First introduced in 1999, the Briz-M space tug replaced the veteran Block-D series as the fourth stage of Russia's workhorse Proton rocket in the 21st century. In 2016, Briz-M got its first opportunity to fly a deep-space mission aimed at sending the ExoMars-2016 spacecraft on a path to the Red Planet

The Proton-M launches the orbital unit (that is: the payload, the payload adapter and the Briz-M) into a slightly suborbital trajectory. The first and second stages and the payload fairing crash into designated crash sites; the third stage crashes into the ocean.

A 1-to-10 scale models of Briz-KM (left) and Briz-M upper stages. Briz-K/KM The Briz (Breeze) rocket stage apparently originated in the 1980s within a Soviet anti-satellite weapons program designed to carry a "killer" vehicle toward its target in orbit.

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 boiling; the Proton-M also flew with a Blok-DM upper stage. Efforts were also made to reduce dependency on foreign (usually Ukrainian ...

Aug 9, 2016 · Improved Proton orbital launch vehicle. Improvements in lower stages to reduce structural mass, increase thrust, and fully utilize propellants (reducing release of toxic chemicals in stage impact areas). Briz M storable propellant upper stage replaces Block D cryogenic stage. AKA: 8K82M;Proton M;Proton/Briz M. Status: Active. First Launch: 2001 ...

On 6 August, 2012, Russia launched two commercial satellites aboard a Proton rocket, and attempted to place them in geosynchronous orbit using a Briz-M upper stage (2012-044C, SSN 38746). Unfortunately, the upper stage failed early in its burn and was left stranded in an elliptical orbit with a perigee in low Earth orbit (LEO).

Mar 7, 2023 · The Briz-M upper stage is hypergolic and features the S5.98M gas generator engine, capable of producing 19.6 kN of thrust. It uses UDMH as fuel and N 2 O 4 as oxidizer. The basis of the control system is the Mars-3M platform developed by the OKB Mars design bureau (located in Moscow, Russia).

New upper stage for Proton, replacing Energia Corporation's Block DM, making Proton an all-Khrunichev launch vehicle. The Khrunichev-built Briz-M upper stage is a derivative of the flight-proven Briz -K stage (as used on the Rokot booster). AKA: Briz M. Status: Active. Thrust: 19.60 kN (4,406 lbf). Gross mass: 22,170 kg (48,870 lb).
