A slipstream is a region behind a moving object in which a wake of fluid (typically air or water) is moving at velocities comparable to that of the moving object, relative to the ambient fluid through which the object is moving. The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it. \"Slipstreaming\" or \"drafting\" works because of the relative motion of the fluid in the slipstream.
A slipstream created by turbulent flow has a slightly lower pressure than the ambient fluid around the object. When the flow is laminar, the pressure behind the object is higher than the surrounding fluid. The shape of an object determines how strong the effect is. In general, the more aerodynamic an object is, the smaller and weaker its slipstream will be. For example, a box-like front (relative to the object's motion) will collide with the medium's particles at a high rate, transferring more momentum from the object to the fluid than a more aerodynamic object. A bullet-like profile will cause less turbulence and create a more laminar flow.
A tapered rear will permit the particles of the medium to rejoin more easily and quickly than a truncated rear. This reduces lower-pressure effect in the slipstream, but also increases skin friction (in engineering designs, these effects must be balanced).
The term \"slipstreaming\" describes an object travelling inside the slipstream of another object (most often objects moving through the air though not necessarily flying). If an object is following another object, moving at the same speed, the rear object will require less power to maintain its speed than if it were moving independently. This technique, also called drafting can be used by bicyclists.
Spiral slipstream, also known as propwash, prop wash, or spiraling slipstream, is a spiral-shaped slipstream formed behind a rotating propeller on an aircraft. The most noticeable effect resulting from the formation of a spiral slipstream is the tendency to yaw nose-left at low speed and full throttle (in centerline tractor aircraft with a clockwise-rotating propeller.) This effect is caused by the slipstream acting upon the tail fin of the aircraft: The slipstream causes the air to rotate around the forward-aft axis of the aircraft, and this air flow exerts a force on the tail fin, pushing it to the right. To counteract this, some aircraft have the front of the fin (vertical stabilizer) slightly offset from the centreline so as to provide an opposing force that cancels out the one produced by the slipstream, albeit only at one particular (usually cruising) speed, an example being the Hawker Hurricane fighter from World War II.
Slipstream is a racing game inspired by the visuals, music, games and cars from the late 80s and early 90s. It's built on a custom game engine, with an authentic retro feel and unique graphics that allows the player to -literally- go back in time. The soundtrack, drawing from synth pop and jazz fusion influences, sets the tone for a race across a variety of exotic locations from all around the world, including cities, deserts, forests, mountains and beaches. Drifting, rewind and slipstreaming mechanics add depth to the driving gameplay, and the result is a challenging and exciting experience.
Slipstream, also known as Streaming, Riding the rails, and FTL, is the only known way of traveling faster than light in the Known Universe. It is currently the sole means of faster than light transit and every race in the known worlds depends upon it for their economies and way of life in every social and political aspect. As such, it can be argued that slipstream is the most important discovery ever made. It was originally discovered approximately 10,000 years before the current era by Vedran scientist Rochinda. The technology that made it possible to utilize the slipstream was invented during the same period, and the first Vedran Empress was crowned a mere 112 years later, as the Vedrans began to spread throughout the Known Worlds.
A Gravity Field Generator drastically reduces the mass of the ship and then a slipstream drive opens a slippoint which the ship enters. The ship then catches onto the strings by means of slipstream runners. Once hooked onto the strings the pilot then navigates the series of slipstream \"strings\" until they reach the desired slippoint where they exit the slipstream.
Since its discovery nearly 10,000 years ago by the Vedrans, the slipstream has connected the galaxies together. Slipstream is an extension of our reality, an additional dimension that's integrally intertwined with our own. The slipstream is a place where quantum connections are visible as cords, especially the large and strong connections like those between huge concentrations of matter such as planets or suns. A spaceship that enters the slipstream can harness the energy of these cords and ride them from one star system to another.
One interesting thing about moving through the slipstream is that travel time between points has very little to do with the distance actually traveled. If a pilot is lucky, and the stream unfolds just right, the ship could transit between galaxies in minutes. But put an unlucky pilot at the helm and the same trip could take weeks or even months.
At an intersection of pathways in slipstream space, both paths manifest the potentiality of being correct and incorrect. It's only when the pilot chooses a specific direction that this potentiality collapses and one path becomes right, and the other wrong. For reasons still not completely understood, organic beings tend to choose the correct paths, or more precisely, the very act of choosing makes the path they have chosen the correct one.
It was thought that computers, even those with Artificial Intelligence, were incapable of this reality-altering guesswork. Even the most sophisticated starship in the Systems Commonwealth has an organic sentient to pilot through the starlanes, a prospect some sentients regard as deeply disturbing but others find comforting. However, machines with organic neural components (i.e.- cyborgs, in this case) have the intuition required to do so. For example, VX of the Consensus of Parts was able to navigate the slipstream because he had these components and thus the intuition required. Thus, an organic brain is required, though the organism itself need not be wholly organic. However, it appears even a full Artificial Intelligence is capable of navigating the slipstream to some extent, albeit in a very haphazard and dangerous way. When the entire original organic crew of the Andromeda Ascendant was killed by the Magog from the Magog Worldship, the Andromeda's Artificial Intelligence made the journey from the galaxy M82 to Triangulum by wandering the slipstream pilotless for 13 months. There was a way for both the pilot and Artificial Intelligence to navigate the slipstream accurately by using slipstream maps recorded in slipscouts such as Deep Midnights Voice.
Due to the complex nature of slipstream probability and difficulty in mapping slipstream, only biological entities are capable of successfully navigating it. Exiting slipstream near the edge of a galaxy or in certain regions of space could be dangerous because it is difficult to find a slippoint in these areas. If a slippoint cannot be found, or a slipstream drive is damaged, the ship is stranded and limited to slower than light speed.
It is unknown whether Slipstream Runners give ships an advantage at riding the superstrings while in slipstream, because while almost every larger Systems Commonwealth ship has slipstream runners that allow them to ride the strings, other ships used by species such as the Magog and Nietzscheans do not have runners but appear to operate in slipstream just as well. The same goes for smaller ships such as the Eureka Maru, which does not have runners.
Slipstream also has \"decision points\", which are basically intersections or natural branchings of the quantum strings that are ridden. Speed in slipstream, although relative, can be used to judge how fast one is going compared to the median times. The Andromeda Ascendant was once piloted by Beka Valentine about 12 times the normal decision point speed.
It was once stated by Andromeda that an Artificial Intelligence attempting slipstream travel has a 50% chance of selecting the correct route at each intersection encountered, owing to organic 'intuition' a living pilot has a greater than 99% chance of guessing the correct route to take.
Discussion on the various matters concerning the internals and development of Slipstream can be carried out on the slipstream-devel mailing lists. Please use these instead of my personal e-mail address for matters that might potentially be of interest to other users as well. Also remember to use the support tracker if you're having trouble getting Slipstream to compile and run properly.
In early 2020, I tackled the definitions and interpretations of speculative fiction. Like speculative fiction, there is another term that lingers somewhere between literary fiction, mainstream, and genre. That is where slipstream comes into play.
Isabel Yap, author of the collection of stories Never Have I Ever, had her first encounter with slipstream while submitting to (and later reading slush for) the now defunct journal Interfictions Online, which specialized in interstitial works.
So if you are looking to experience slipstream, search for the stories that readers find hard to define. Books just left of center. Different. Resistant to labelling. Perhaps genre but not genre enough for some readers. Stories that hold tight to the world we know, but with just enough off kilter to make us feel unbalanced, weird, and feeling, quite frankly, very strange indeed.
