"Science fiction operates a little bit like science itself, in principle. You've got thousands of people exploring ideas, putting forth their own hypotheses. Most of them are dead wrong; a few stand the test of time; everything looks kind of quaint in hind"
- Peter Watts

Reaction-Motors  
  A spacecraft engine that works by firing matter out at high speed.  

This idea makes use of conventional physics.

For three days Captain Grant had kept his great space-liner… ahead of the questing disintegrator rays of the Black Hawk only by burning his full battery of reaction-motors at their maximum power.
Technovelgy from Twelve Hours To Live, by Jack Williamson.
Published by Wonder Stories in 1931

Here's what the drive looked like in operation:

…Grant saw a vague pink glow come into being in the jet, star-sprinkled sky behind…

The glow, he knew, was a fluorescent, electronic discharge in the radioactive gases jetting from the rockets of the racing ship...

The idea behind a reaction-motor is Newton's Third Law of Motion, which decrees that for every action, there is an equal and opposite reaction. For a spacecraft to move forward, you must throw matter out the other end.

Compare to the reactionless drive idea, which encompasses the various hyperdrives that allow a ship to move from one point to another in space, without traversing the space in between. See the inertialess drive from 'Doc' Smith's 1934 novel Triplanetary.
