Thruster

A thruster is a propulsive device used by spacecraft and watercraft for station keeping, attitude control, in the reaction control system, or long-duration, low-thrust acceleration.

Spacecraft thrusters

  • Rocket engine, using exothermic chemical reactions of the propellant(s)
  • Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere)
  • Electrostatic ion thruster, using high-voltage electrodes
  • Ion thruster, using beams of ions accelerated electrically
  • Hall effect thruster, a type of ion thruster
  • Pulsed inductive thruster, a pulsed form of ion thruster
  • Magnetoplasmadynamic thruster, electric propulsion using the Lorentz force
  • Electrodeless plasma thruster, electric propulsion using ponderomotive force
  • Pulsed plasma thruster, using current arced across a solid propellant
  • Marine thrusters

  • Azimuth thruster, pod underneath a ship, instead of a propeller and rudder
  • Bow thruster, or stern thruster, at the bow or the stern of a ship or boat
  • Rim-driven thruster, electric motor and propeller combined in single unit
  • Simon Anderson

    Simon Anderson (born 7 July 1954) is an Australian competitive surfer, surfboard shaper, and writer. He is credited with the 1980 invention of a three-fin surfboard design, called the "thruster", which remains the industry standard.

    Early life

    Anderson grew up in the Northern Beaches area of Sydney with three brothers. His family lived in a house that overlooked Collaroy Beach. In 1977, he won the junior division at the Bells Beach Classic Easter competition and began shaping surfboards in the Sydney suburb of Brookvale.

    Career

    In 1975, Anderson started his own surfboard factory, Energy Surfboards, in Brookvale. In 1977 he won the Bells Beach Classic competition and the Coke Surfabout in Sydney.

    In October 1980, after seeing a twin fin surfboard with a "trigger point" fin Anderson had the idea for a new version of the existing three fin design which was later dubbed the "thruster". Anderson created a prototype for the "thruster" design and took it on tour with him to Hawaii and California. When he returned to Sydney, he made two more surfboards with similar designs. Using one of those surfboards, he again won the competition at the Bells Beach Classic in 1981 and "surfing history took its biggest turn since polyurethane foam" as the "thruster" design became the most popular fin design for surfboards over the next 30 years.

    Brian Bonsall

    Brian Eric Bonsall (born December 3, 1981) is an American former child actor. He played Andrew "Andy" Keaton, the youngest child on the NBC sitcom Family Ties from 1986 until 1989, and Alexander Rozhenko, the son of Worf and K'ehleyr, on Star Trek: The Next Generation from 1992 to 1994.

    Early life and acting career

    Bonsall was born in Torrance, California. At the age of five, he won the role of Andy Keaton on the sitcom Family Ties. Bonsall won three Young Artist Awards for his performance on the series. He was also nominated for a Young Artist Award for his starring role in the made-for-TV movie Do You Know the Muffin Man? in 1990.

    He made his feature film debut in 1991 in the horror film Mikey, playing the title role, a demonic young boy who murders his parents and terrorizes his adoptive parents. This caused controversy in the UK owing to its depiction of a child killer at a time when the murder of James Bulger had raised sensitivity about violent behavior by children. The film was initially passed uncut by the British Board of Film Classification, but its certificate was withdrawn by James Ferman in the wake of the Bulger killing.

    The Rooster

    by: Atmosphere

    Blue collar Eddie and his better half Delores used to be mantel pieces down at the Black Forest.
    And I don't know if that bar still exists, but when it did, so did they, a couple bleeding heart kids.
    Everything volatile, every night rocker style. Hop a stool, be discrete and just watch a while.
    But do your best to keep the level observational, drama is attractive so push it when it takes a pull.
    And each night's a random when you pay a ransom for the right to sing along with them drinking anthems.
    And these fools paid so many dues that everybody stops to salute.
    But one night after another fight a couple from an opposite table offered an invite.
    Dolores didn't want to join 'em, wasn't feeling social.
    But Eddie was so aggravated that he had to poke holes.
    He walked over, sat in the dialogue and called at Dolores like some kind of dog (hey girl come here)
    She can't believe it, she's done, she's had it, but she doesn't want to make another scene in this establishment.
    She got up and mosied over, and put her arm up around Eddie's shoulder.
    Nobody's sober the song is the same; sometimes you stick out your chin to catch the rain.
    You can be a winner, you can be a loser, gotta wake up when you hear the rooster.
    Sometimes it's just too simple to live your life wrong, gotta do what right for you when the time comes.
    You can be a winner, you can be a loser, gotta wake up when you hear the rooster.
    Sometimes it's just too simple to live your life wrong, gotta do what right for you when the time comes.
    The clock keeps drinking, they keep ticking. There's two more people who get to play positions.
    Samantha and Chuck; not a couple, just roommates; out having too many shots on a Tuesday.
    Who knew they'd be tools for the duo, put a little bit of fire on the fuel.
    It's a kinda blue, intentions ain't cruel, but everybody's so ready to bend up the rules.
    Now there's Chuck, staring at Delores.
    Eddie is distracted by Samantha so he doesn't notice.
    And everybody's too fucked up to even asses the mess, much less care enough.
    More whiskey, a pitcher of Premium, Eddie's getting tipsy, he didn't see it comin.
    On his way back from a visit with that urinal, tryna straighten out his thoughts and the vertigo.
    Weaves through, stops when he's seen em.
    Picture perfect, it looked just like freedom.
    Dolores on Chuck's lap kissing him hard. Eddie dipped into the winter left them all at the bar.
    Sometimes ya gotta follow what's felt inside; between the power struggle and the selfish pride.
    No one's allowed to cry unfair because now they both get to drink alone somewhere.
    You can be a winner, you can be a loser, gotta wake up when you hear the rooster
    Sometimes it's just too simple to live your life wrong, gotta do what right for you when the time comes
    You can be a winner, you can be a loser, gotta wake up when you hear the rooster
    Sometimes it's just too simple to live your life wrong, gotta do what right for you when the time comes
    You can be a winner, you can be a loser, gotta wake up when you hear the rooster
