A m/s vertical drop simulate of a full composite fuselage section was conducted with energy-absorbing floor to evaluate the crashworthiness features of the fuselage section and to predict its dynamic response to dummies in future. The m diameter fuselage section consists of a high strength upper fuselage frame, one stiff structural floor and an energy-absorbing subfloor constructed of Author: Hai Bo Luo, Ying Yan, Xiang Ji Meng, Tao Tao Zhang, Zu Dian Liang.

During the first year of the research program, a er, 1/5-scale model composite fuselage was de-signed, fabricated, and tested to verify structural andflight-load requirements [3].

During the second year ofthe research program, energy-absorbing subfloor configu-rations were evaluated using quasi-static testing and finite.

The development of the fuselage concept is described including the fabrication of a in. diameter full-scale fuselage section that is manufactured using a composite sandwich construction.

From a scaling perspective, the weight of the 1/5-scale fuselage section should equal the weight of the full-scale fuselage section (1, lbs.) divided by 53, orwhich is lbs.

Thus, the 1/5-scale model fuselage section is lbs. heavier than by: 5.This methodology is implemented in a computer code IPACS (integrated probabilistic assessment of composite structures). A fuselage-type composite structure is analyzed to demonstrate the code's capability.

The probability distribution functions of the buckling loads, natural frequency, displacement, strain and stress are by: fuselage and a composite fuselage is also presented showing the less weight advantage of the composite fuselage.
