Vehicle

See also: Enhanced motion vehicle

Guests board an Enhanced Motion Vehicle (EMV) intended to appear as a battered military troop transport. EMVs ride on neoprene filled tires (for operational precision) driven by brushless DC motors in the wheel hub atop the surface of a slotted roadbed. The track has only three switches: a left/right split switch just before loading/unloading, a left/right combine switch just after safety check station/dispatch and a compound switch to swap vehicles in/out of the maintenance bay, behind the mirrors. Beneath the slot a tubular guideway guides the front wheelset and a damper for the rear wheelset, and three electrical buss bars provide the EMV 480 volts AC. The power is divided among the two motion systems, control, safety and audio systems. Each transport can accommodate twelve guests with three rows of seats, four across, with the front left seat behind a non-operational steering wheel. Each troop transport is a motion simulator which travels at a maximum speed of just over 14 miles per hour (23 km/h) atop a slotted roadbed / guiderail track. The transport carbody is attached by three hydraulic rams to the frame of the chassis, and allow the shell to articulate independently. A guest's physically intense experience is programed to achieve the illusion of greater speed and catastrophic mechanical failure using the enhanced-motion vehicle's ability to add several feet of lift then rapidly descend, shudder and tremble, and intensify cornering with counterbank and twist.

This ride system was invented for the Indiana Jones Adventure, and has only been implemented in two other attractions – DINOSAUR, located at Disney's Animal Kingdom (opened as CTX: Countdown to Extinction) in Orlando, Florida, and its Tokyo DisneySea counterpart, Indiana Jones Adventure: Temple of the Crystal Skull. However, the Japanese version uses linear-inductive actuators instead of three hydraulic rams. The 35 gallons of hydraulic fluid used on the Disneyland version takes two hours to clean up the track when a hose splits. Because of Japan's environmental codes regarding oil spills, the design team elected to substitute electromagnetic actuators on the ride vehicle. Three of these actuators are used to create a 3-D (pitch, roll, and elevation) motion platform chassis on which the carbody sits.

Famous quotes containing the word vehicle:

    “The woman may serve as a vehicle for the rapist expressing his rage against a world that gives him pain—because he is poor, or oppressed, or mad, or simply human. Then what of her? We have waded in the swamp of compassion for him long enough.”
    —Robin Morgan (b. 1941)

    “You utilitarians, you too love everything useful only as a vehicle of your inclinations—you too really find the noise of its wheels intolerable?”
    —Friedrich Nietzsche (1844–1900)

    “Its idea of “production value” is spending a million dollars dressing up a story that any good writer would throw away. Its vision of the rewarding movie is a vehicle for some glamour-puss with two expressions and eighteen changes of costume, or for some male idol of the muddled millions with a permanent hangover, six worn-out acting tricks, the build of a lifeguard, and the mentality of a chicken-strangler.”
    —Raymond Chandler (1888–1959)
