An Impulse roller coaster is a form of a launched inverted roller coaster manufactured by Intamin. The first Impulse roller coaster appeared in Japan, and the ride type has since evolved to include four specific layouts, three of these varieties being built in the United States. It uses LIMs to launch a train out of the station and (in most installations) up a vertical spiral. The train then falls backward, is powered again through the station, and heads up a back tower. The train then falls forward, and continues in this fashion for a total of 2½ cycles per ride (three forward launches, two backward). On the final forward launch, with a slightly reduced speed, the train is sent up the front tower, and brakes then deploy on the launch track. The train then slows down and heads back into the station.




The original


The original Inverted Impulse roller coaster, Linear Gale, was built in 1998 at LaQua Amusement Park at Tokyo Dome City in Tokyo, Japan. Like the more modern Impulse roller coasters, it began with a LIM launch. However, instead of going through a vertical twist, it simply headed up a straight tower. It headed backward through the launch section and station and into another vertical tower of track, this time facing the ground. After a few more cycles, the train slowed and came to a stop in the station. It closed on October 31, 2010.

The first installation in the United States was Superman: Ultimate Escape at Six Flags Ohio in Aurora, Ohio. Built in 2000, it was the first Intamin Impulse roller coaster to feature a vertical twist and a holding brake on the rear tower. However, Wicked Twister built in 2002 at Cedar Point in Sandusky, Ohio, did away with the straight section containing the holding brake and instead had a second twisting tower, however this coaster permanently closed in 2021. The Flash: Vertical Velocity at Six Flags Discovery Kingdom in Vallejo, California originally had the twisted front and vertical rear towers when it was built in 2001 (also then known as V2: Vertical Velocity). However, upon discovery of exceeding the 150 ft. height restriction in the Vallejo area, the ride was altered to have a front section slanting at 45 degrees into an inline roll which ended with a straightaway, and the rear tower was lowered to the 150 ft height limit. The holding brake was also turned off, and has not been used since. The ride reopened in 2002, and is unique among Inverted Impulse roller coasters for being the only one with an inversion as the vertical spikes on other Impulses are not inversions. In 2004, Superman: Ultimate Escape was renamed to Steel Venom after Six Flags sold Six Flags Worlds of Adventure (which Six Flags Ohio had been renamed to after merging with adjacent SeaWorld Ohio in 2001) to Cedar Fair and the park reverted to its original name Geauga Lake. It operated under that name until the end of Geauga Lake's 2006 season and then was moved to Dorney Park & Wildwater Kingdom in Allentown, Pennsylvania. In 2008 the ride opened under the name Voodoo but was changed to Possessed the following year. The ride continues to operate at Dorney Park. Steel Venom at Valleyfair was the last brand-new Impulse Coaster to be installed for 18 years. However, in 2021, Chongqing Sunac Land in China opened Legendary Twin Dragon, stealing Wicked Twister’s record as the tallest Impulse Coaster in the world at 230 ft. This installation uses the more modern LSM launch system to launch trains instead of the LIM one used on the previous installations, while also featuring Intamin’s newer high-stress track design.

Although technically not an Inverted Impulse coaster, Volcano: The Blast Coaster utilized technology that would eventually be included in Impulse designs. It was manufactured by Intamin, the same company that manufacturers modern Impulse coasters; thus it utilized LIM motors, trains, and track structure similar to modern Impulse coasters. However, it was unlike Impulse coasters because of its full circuit, multiple train, dual-launch design. It had 2 launches, first to 68 mph and second to 70 mph. In February 2019, Kings Dominion announced that Volcano would be demolished before the 2019 season, citing maintenance issues.

Impulse is a steel roller coaster located at Knoebels Amusement Resort in Elysburg, Pennsylvania. It is manufactured by Zierer and is the first major steel coaster to open at Knoebels since Whirlwind closed in 2004. Impulse was the park's most expensive addition when it was completed in 2015.




History



The park had been looking for a new roller coaster after Whirlwind was closed and shipped to Parque de Diversiones in Costa Rica in 2004. The park hired German manufacturer Zierer Rides to design the new ride. The actual design process did not start until 2009. Construction began in July 2013, and the coaster was assembled at the park in late February 2015. The project was complete by April 2015.
Impulse replaced the Bumper Boats ride, which was purchased from Rocky Glen Park in Moosic, Pennsylvania in the 1980s.




Ride experience


Riders are restrained by a lap bar which goes across the legs and the waist. The ride features three cars, each of which seats eight riders.
The ride begins with the car making a right turn out of the station, before climbing up a vertical 98 ft (30m) lift hill. Upon cresting the lift, the car immediately plummets down a 90 degree vertical drop (during which the on-ride photo is taken) into a cobra roll. After completing the cobra roll, the car passes through a short section of straight track before completing a vertical loop. The vertical loop is followed by an elevated right turn passing over the entrance to the nearby Scenic Skyway, after which the car dives down into an upward counterclockwise helix which wraps around the lift hill. Upon completing the helix, the car passes through a heartline roll that threads through the vertical loop. This is followed by a clockwise 540 degree helix, after which the car hits the brake run and returns to the station. One cycle of the ride lasts one minute and 20 seconds.
