Disambiguation

NOT to be confused with turbofan engine boosters (internal compressor stages); refers to auxiliary rocket engines or JATO systems providing additional thrust for launch or takeoff.

Concept

A rocket or rocket engine providing auxiliary thrust during launch, typically in the first stage of a multistage vehicle or in parallel configuration, and separated after fuel expulsion.

Um motor de foguete ou foguete que fornece empuxo auxiliar durante o lançamento, tipicamente no primeiro estágio de um veículo multietápios ou em configuração paralela, sendo separado após o esgotamento do combustível.

• Booster (rocketry)
  Wikipedia▎ high· 2026-05-14
  • Booster engines are rockets used in first stage or parallel configuration to augment takeoff thrust
  • BECO (booster engine cut-off) is the point when fuel expires and booster separates
  • Three main types: drop-away, strap-on, and recoverable boosters
  • Modern reusable designs exemplified by SpaceX Falcon 9
• SLS (Space Launch System) Solid Rocket Booster
  NASA▎ high· 2026-05-14
  • SLS booster: 177 feet tall, 12 feet diameter, 1.6 million lbs each
  • Each generates 3.6 million lbs thrust; consumes ~6 tons propellant/second
  • Twin boosters provide 75% of total SLS thrust at launch
  • Five-segment design provides 25% more impulse than Space Shuttle four-segment variant
• Space Shuttle Solid Rocket Booster
  Wikipedia▎ high· 2026-05-14
  • First solid-propellant rockets used for primary propulsion in human spaceflight
  • Each provided ~14.7 meganewtons thrust, ~85% of vehicle's total thrust at liftoff
  • Propellant composition: ammonium perchlorate (69.6%), aluminum powder (16%)
  • SRBs separate at ~146,000 feet altitude via explosive bolts; recovered via parachute
