On the launch of 20 October 2012, Roland Lemmers asked if photographs could be taken of a test with a 2-stage model. The booster (bottom/1st stage) was taped to the launch platform, so the whole of ignition of 1st and 2nd stage could take part in front of our nose. Aim a high-speed camera on it and we´re ready. Below the result. Between consecutive frames we have 0,067sec. You can click on the pictures to enlarge. It opens in a new window. |
1: Booster motor fires. Point in time: +0,20sec./Frame3-25. |
