This drop tester is situated within the blast chamber. Consequently multiple loading conditions such as blast and impact loads in sequence is achieved. The drop tester was built to primarily investigate the structural response of thin-walled structures subjected to axial impact load at relatively low impact velocities. This 7m structure can achieve a maximum drop velocity of 10m/s at a drop height of just over 5m. With a maximum drop mass of 500kg, a resulting 25kJ of energy can be achieved.
