Description
Summary:The paper presents certification programme of an airframe primary structure composite part (pressurized bulkhead). Within the test the mechanical (static and fatigue) and environmental loading was simulated. The environmental loading is represented by 70 °C temperature and 90% humidity. The proposal and realization of the whole certification programme in the Aeronautical Research and Test Institute (VZLU) is presented. The designed programme fulfilled the conditions of the FAR-23 (or CS-23) regulations requirements. The composite bulkhead was designed and manufactured during the development of a new small Czech air carrier with pressurized fuselage. The bulkhead is honeycomb structure with carbon/epoxy skin. The technical and operational testing conditions, test facility possibilities and follow-up details related to the structure certification are stated. Results from residual strength test and results from advanced non-destructive testing are presented (Shearography method).
