A combined analytical and experimental program was undertaken to study the dynamic structural response of aluminum model aircraft fuselage structures (nominally 36 inches diameter by 91 inches long). A drop-test gantry was used to provide a simulation of the wheels-up landing condition for both level and oblique angle impacts on a concrete pad for a range of wing loads and vertical descent velocities. Dynamic measurements of strain and g loads at discrete locations were obtained together with high speed photographs of the failure modes for comparison with a lumped mass-stiffness model of the structure using a finite element approximation.
