The Catapult Competition Is On!

29 March 2003

The Composite Catapult Competition, organized by the European Pultrusion Technology Association EPTA is set to be a huge success. 12 teams from all over Europe and one from the USA have entered this exciting event.

The competition will be held 9-11 July on the military shooting grounds of the Royal Netherlands Artillery Kazerne in ‘t Harde,just South of Zwolle. Catapult shooting Ground Teams consisting of 4 students and one tutor are to design and build a catapult.

These catapults are to be built of pultruded reinforced standard off-the-shelf composite profiles.The engineering design should be based on known material properties,such as strength and stiffness,based on manufacturers data. These data will be supplied by the various pultrusion Member companies of EPTA. There is a special Rule Book for the teams.

EPTA has received formal approval of the Netherlands Ministry of Defence to conduct the Catapult Shooting on one of the most attractive locations for this shooting,the LFD ‘t Harde, Artillery Basis at Oldebroek.(10 km South of Zwolle and 100 km North- East of Amsterdam).There is a Railway Station about 3 km.away from the main gate. This location has everything what is needed for the shooting.

A successful design will launch a projectile (a hard rubber bowling ball of 6 kg.)which will impact a designated target with a high degree of accuracy. The catapult design should include provisions for adjusting the range of the impact point. Each team should develop their operating rules, including rules of conduct, roles and responsibilities, decision-making, conflict resolution, peer reviews and record keeping.

The first Prize, sponsored by Bekeart of Belgium, is a trip for the winning team (4 students and 1 tutor)to the Mediterranean Island of Malta. Malta is well known for its well preserved Fortifications,where at one time Crusaders had their strongholds. Many times these forts were attacked with the aid of ,in those days considered advanced artillery, the Catapult.
