Inversions are elements of a roller coaster that turn the train upside-down. They are most commonly found on steel roller coasters, however, Outlaw Run and Hades 360, wooden coasters, feature inversions.
Types of Inversions Edit
Barrel Roll EditA Barrel Roll (also known as a "Heartline Roll") is an element in which the track twists 360° around the train, leaving the train twisting in a straight line around the line of riders' center of balence (at about heart level, hence the name).
A Batwing is a double inversion which flips over a 90° half-corkscrew and a half-loop followed by the same maneuver in reverse. Arrow Dynamics calls this element a boomerang.
A Bowtie is a double inversion similar to the Batwing, but the 2nd half-corkscrew is flipped, making the vehicle exit the inversion the same way it entered. It has only appeared (so far) on Dragon Mountain at Marineland.
Cobra Roll EditA Cobra Roll is a double inversion consisting of a half-loop, followed by two mirrored half-corkscrews, and finishing with another half-loop. Arrow Dynamics calls this element a batwing.
Corkscrew EditA Corkscrew is an inversion that resembles a vertical loop that has been stretched so that the entrance and exit points are a distance away from each other. It is basically a combination of a loop and a barrel roll. The riders are inverted at a point angled 90° horizontally from the incoming track. Often Corkscrews are found in pairs. You also occasionally see triple corkscrews.
Cutback EditA Cutback is an inversion similar to a Corkscrew, except, the second half is mirrored, so that the train exits the inversion in the opposite direction from which it entered. The now defunct Drachen Fire featured a cutback.
Dive Loop EditA Dive Loop is an inversion that starts like a normal hill, then when it reaches its maximum steepness, does a corkscrew-like twist (which horizontally can range from straight to a curve over 135º) into a downwards half loop. When traveled in reverse it is usually called an "Immelman".
Inclined Loop EditAn Inclined Loop (or a Tilted Vertical Loop) is a Vertical Loop that has been "tilted" at an angle. It is not entered vertically, like a standard loop, or horizontally like a helix. Instead, it is usually entered at an angle between 45° and 80°.
Interlocking Corkscrews EditInterlocking Corkscrews are parallel (or near parallel) Corkscrews that cross over each other in opposite directions.
Interlocking Loops EditInterlocking Loops are perpendicular (or near perpendicular) Vertical Loops that cross over each other, making a similar shape to that of a chain.
Norwegian Loop EditA Norwegian Loop is a Dive Loop and an Immelmann traveled in succession.
Sea Serpent Edit
A Sea Serpent (known as a Roll Over on Vekoma coasters) is an inversion pair that is very similar to a Cobra Roll, only the Corkscrew halves have a constant twist and curve in in the same direction (rather than mirroring the second half).
Sidewinder EditA Sidewinder is half of a Vertical Loop combined with half of a Corkscrew.
Vertical Loop EditThe most generic roller coaster inversion is a vertical loop. The loop is a continuously upward-sloping section of track that eventually results in a complete 360° circle. At the top-most piece of the loop, riders are completely upside-down. The continuously upward slope often increases relatively as the altitude increases to average the G-Forces (this is often called a "Teardrop Loop").
Zero-G Roll EditA Zero-G Roll (sometimes called a "Spiraling Camelback) is an inversion that is similar to a barrel roll but starts and ends vertically inclined like a standard hill. The inversion resembles a hill with a barrel roll on top.
Zero-G Stall Edit
Similar to a Zero-G Roll, a Zero-G Stall levels out upside down at its highest point, twisting at the ends before leveling off at or near ground level.
Top Gun Stall Edit
Similar to the Zero-G Stall, but the second half of is mirrored.
