  2. an enthusiastic supporter.

Booster

Booster may refer to:

Booster (electric power)

A booster was a motor-generator (MG) set used for voltage regulation in direct current (DC) electrical power circuits. The development of alternating current and solid-state devices has rendered it obsolete. Boosters were made in various configurations to suit different applications.

Booster (HUSS ride)

Booster is an amusement park ride made by HUSS Park Attractions.

Booster is an evolution of the HUSS's Breakdance ride, and a competitor of Mondial's Shake and Fabbri's Crazy Shake rides. The basic movement is the same as these rides, but the car is pivoted so that riders are spun sideways. During the ride, the cars frequently flip riders upside down. Most parks require riders to be at least 52 inches or taller.

Booster (Fabbri ride)

Booster is an amusement ride made by Fabbri.

It is a pendulum ride, similar to the later Speed by KMG (which, due to its similarity to the Fabbri ride, is often referred to as the KMG Booster)..

There is another ride from the Italian company, Zamperla. Zamperla made a booster like ride called Turbo Force made in 2001.

Booster (rocketry)

A booster rocket (or engine) is either the first stage of a multistage launch vehicle, or else a shorter-burning rocket used in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. (Boosters used in this way are frequently designated "zero stages".) Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are certainly necessary for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO). The rest of the launch vehicle continues flight with its core or upper-stage engines. The booster may be recovered and reused, as in the case of the Space Shuttle.

Strap-on boosters are sometimes used to augment the payload or range capability of jet aircraft (usually military).

Usage examples of "booster".

Yoshiko experimented for a few minutes with the hand controller, getting the feel of the thrusters, while Tessa filmed the whole process, showing the people back home the ungainly, angular LM perched atop the spent third stage booster, and Yoshiko peering out the tiny windows as she concentrated on bringing the CSM around until the docking collar at the top of the capsule pointed at the hatch on top of the LM.
