Design, Fabrication, Test and Analysis of a Crashworthy Troop Seat.

摘要

In the Netherlands, more troop carrying helicopters are flying more 'passenger-miles' in peace time operations than before. These helicopters were designed before crashworthiness was a severe design issue. NLR is evaluating if the crashworthiness of existing helicopters can be upgraded significantly by retrofitting crashworthy troop seats. Within this framework a generic research investigation was undertaken to design and fabricate (NLR), test and analyze (TNO) a generic troop seat, to obtain a baseline configuration and characteristic to be used for the assessment mentioned above. The test results indicated that the seat design was satisfactory, but the energy absorbing crash tube needs to be optimized, including the break initiation mechanism. The MADYMO crash simulation package predicted the test results well and has potential for optimization studies.
