Abstract : In the scope of the development of the Trojka drone a test structure has been subjected to 2 series of 3 underwater shock loads of increasing shock levels. During these tests TNO carried out measurements with 24 strain gauges, 28 accelerometers, 4 relative displacement transducers and 2 pressure transducers. This report presents the measured pressure signals, strain signals, relative displacements, accelerations, the calculated maximax shock response spectra (at 1% damping) and, by integration of the accelerations, velocities and displacements, of the second series of 3 measurements.
