  • Interesting fact: From 1836 to 1896, the Red Flag Act in England required that any self-propelled vehicle be preceded by a man carrying a red flag by day and a red lantern by night. In effect, this limited the speed to four miles per hour and retarded the development of all self-propelled vehicles, including the automobile.
    • n propeller One who or that which propels; in marine engineering, broadly, any contrivance or appliance, as a sail, paddle, oar, paddle-wheel, screw, etc., used for moving vessels floating upon the surface of water, or under the surface; in a more restricted and more generally accepted sense, any instrument or appliance, and especially a screw, used for marine propulsion and actuated by machinery (usually a steam-engine called a marine engine) carried by the vessel so propelled. A principle common to all this class of propellers is that a vessel is moved forward by the reaction on the propeller of the water thrown rearward, the propelling machinery being at some part or parts rigidly attached to the ship. The net propelling power is therefore determined by the mass of water thrown rearward multiplied into the square of the velocity with which it is thrown, allowance being made for prejudicial resistances.
    • n propeller A boat or vessel driven by a propeller.
    • n propeller In fishing, a kind of trolling-hook with artificial bait, fitted with wings or flanges to make it spin in the water; a spinning-bait.
    • n propeller See the qualifying words.
    • n propeller In electricity, in the tangential system of traction, the moving part of the system, corresponding to the rotor of an alternator, which is drawn along by the inductive action of the stator-coils between the track and thus affords motive power for the attached cars.

Before a local sense has jelled,
From talking-site to talking-site
Am jet-or-prop-propelled.

For the slow measure timed her peal of bells.

In order to reduce the accretion rate onto the neutron star (three orders of magnitude are needed) an ADAF model has therefore to involve the presence of winds and/or the ejection of the accretion flow by the magnetic field of a rapidly rotating neutron star: the ‘propeller effect’ (Menou et al. 1999c).

Tomov et al., 1994) it is assumed that in the passive state the white dwarf accretes gas under propeller condition, while in the active state (e. g. in periastron the rate of accretion onto the magnetosphere rises and, correspondingly, the magnetosphere size is reduced) the star become the accretor.
