Evaluation of numerical modelling application for the crash test planning of the catastrophic Flight Data Recorder

Catastrophic Flight Data Recorders (FDRs), the so-called black boxes, belong to the on-board equipment, the task of which is not only to operate properly while recording selected parameters under all flight conditions but also to protect the recorded data against the loss in the aircraft crash conditions. The requirements related to catastrophic resistance of FDRs are defined in the European standard EuroCAE ED-112 and the Polish standard NO-16-A200:2015. One of the requirements includes the catastrophic recorder’s resistance to the acceleration overload of 3400 g. The compliance with the standard is checked during crash tests. In this paper, a procedure of planning and carrying out the mentioned tests for S2-3a-K protected unit of S2-3a catastrophic FDR manufactured by the Air Force Institute of Technology was described. It is an iterative procedure involving consecutive experimental tests and both analytical and numerical calculations. The experimental tests were performed using a DPZ-250 pneumatic gun. The testing probe was shot at the target of sand deposits of modified geometry and mass characteristics. Effectiveness of the developed procedure was shown by comparing the experimental results, namely recordings of the probe deceleration captured with a fast camera, with results of numerical simulation of the probe terminal ballistic.
