Catapult Index


Machines sorted by type and size:

Catapult Style Description Small Medium Large
Traditional Trebuchet Traditional trebuchets are historocal catapults powered by a counterweight, usually with a heavy weight on one side of the arm, and a sling and projectile hanging off the other.
Traction Trebuchet Traction trebuchets are historocal catapults powered by humans pulling on ropes, effectively acting as the counterweight as with traditional trebuchets. Traction trebuchets are the easiest to create and operate, as you don't have lots of weight to bring with you. You do, however, need to train the counterweight crew.
Ballista Ballsitas are torsion engines origianly designed around 400BC. They are powered by two bundles of twisted rope, and arranged in the form of a big crossbow.
Hatra Ballista Hatra Ballista is a torsion engine with two bundles. Unlike the greek ballista, a Hatra ballista is configured so the bowstring and arms rotate toward the center, providing a much better configuration for throwing heavy objects.
Onager Onagers are torsion engines, designed with a single bundle, and an arm and sling.
Air Cannons Air Cannons use a resevior of compressed air behind a valve. When the valve is opened, it will push the projectile down the barrel. Pnuematic cannons are similar to other kinds of cannons, but without the use of explosives.

Notes Micro Trebuchet Cam Trebuchet Cardan Trebuchet Scissor Trebuchet
Modern Trebuchet Models Modern Trebuchet Models use couterweights, but use different mechanics to take better advantage of the available power.
Notes Pumpkin Putter Universal Torsion Machine Kid-A-Pult
Other Machines Other machines we built, some went to competitions, and some just for fun.
