Placing eight Olympus i-SPEED 3 high-speed video cameras around the largest rocket to have been fired in the UK in 25 years was always going to be a challenge. Add difficulties such as the fact that the test was to be run in a sealed bomb-proof hangar, communications and control was to be run 350 metres to a second command hangar and that the test by it’s very nature was a one-off all combined to make this one of the most challenging tests conducted by Olympus.
Cameras were set to record at 500 frames per second with a 400 microsecond shutter speed and an exposure of F16.
The cameras were set, record mode activated 2 hours prior to the test and nerves frayed while waiting for the “go” signal. Once set there was no going back as the hangar was in lock-down. On firing, the rocket produced a plume some 15 feet long and a corresponding noise to match! Despite melting the lenses on some of the i-SPEED cameras due to their close proximity to the plume all eight recorded stunning slow-motion video footage which will prove invaluable to the rocket team for the analysis of their rocket burn.
