・ The generation and propagation of shockwaves

Satellite and rocket debris, referred to as space junk, circles the earth at high speeds in satellite orbits. Space junk causes problems when it collides with spacecraft in flight, causing damage.
In addition, in recent years, the conversion of aircraft parts to carbon fiber reinforced plastics (CFRP) has advanced. However, aircraft experience lightning strikes and collisions with birds and hail midflight, so the impact resistance of materials and the damage caused by these occurrences must be investigated beforehand.
In the development of aerospace materials, high-speed cameras are used to investigate the failure behavior of materials caused by high-speed flying objects, and the deformation and failure behavior of materials caused by high-speed impacts. In addition, high-speed cameras are utilized for the development of thrust generators, aerodynamic design via wind tunnel tests, the observation of damage in lightning strike tests, and basic research into shockwaves, detonation waves, and other high-speed wave motion phenomena.

High-Speed Collision of a Transparent Laminate with a Resin Sphere

Experimental Setup of High-speed Collision

These images show the failure process caused by the high-speed collision of a resin sphere (nylon sphere) with a block of a transparent laminate (polycarbonate). The images illustrate the production and growth of cracks inside the block due to the stress wave caused by the collision.
Experimental Setup of High-speed Collision

A resin sphere is injected at 3.5 km per second from the gas gun. The high-speed collision of a transparent laminate with the resin sphere is captured in the backlight system to face the camera and strobe light.

CFRP Lightning Strike Test

Lightning strike tests are used to investigate damage from lightning strikes to carbon fiber reinforced plastics (CFRP), which are increasingly used as structural materials for aircraft. The image illustrates the instant gasification of the resin by the lightning current flowing along the direction of the CFRP fibers.

Recording speed: 1 million frames/second

Supersonic Wind Tunnel Test

Sonic booms, the shockwaves generated by ultrasonic passenger planes, cause a thunderous noise on the ground, so aerodynamic designs are studied as a means to reduce this problem. The image shows a Mach 2 ultrasonic wind tunnel test. Subtle variations in airflow are captured by the high-speed camera.

Recording Speed: 200,000 frames/second
Width of field of view: Approx. 80 mm
