Two pneumatic cannons that are used for impact tests. The pneumatic cannon is used to test the strength of structural elements in crash tests with objects moving in relation to them at high speeds. The cannons allow to shot objects, most often bird analogue gel projectiles, using the energy of compressed air stored in pressure tanks (“Bird Strike”).
200MM PNEUMATIC CANNON FOR IMPACT TESTS
The cannon is used to test objects in Crash tests, (high-speed impact tests) – e.g. material specimens and aircraft structures or their components, e.g. floor panels, engine inlets.
Specification of the stand:
Velocity up to 200 m/s (for 0.3 kg projectile mass).
Test object diameter up to 200 mm.
Projectile mass up to 5 kg.
Remote firing.
Compact design for working outside the laboratory.
Data acquisition and measurement system.
Phantom VEO 410L high-speed camera with tracking using TEMA Motion software.
DPZ-250 PNEUMATIC CANNON
