Keywords: helicopter subfloor, crashworthiness, experimental tests, nonlinear finite element analysis

Tests were performed to improve the design of a new helicopter subfloor. Various intersection designs and a portion of the subfloor were initially tested. Then, a full scale drop test was carried out. In parallel, simulations were run and the results compared with the test data.
