Bungee Powered Amusement Ride Trebuchet
This interesting modern variation of a traction trebuchet
uses multiple elastic bungee cords in tension for motive force. From the
United States Patent Abstract:
Human Free Flight Catapult
An amusement ride for catapulting a human rider, enclosed within
a capsule, into the air in much the same fashion as ancient armies would
hurl large boulders over the walls of castles. The catapult provides many
of the sensations and thrills encountered by fighter pilots launching from
the decks of aircraft carriers without the requirement for flight training
or the associated dangers.
The ride essentially consists of a siege catapult and launch pod connected
by a sling . When in the launch position, a release mechanism is triggered
by the operator and the rider is hurled into the air at a physiologically
safe rate of acceleration along a predictable free-flight arc.
When an acceptable elevation is reached, the rider is separated from the
capsule and gently brought back to earth using an automatically deploying
parachute or similar device.
