Pagination or Media Count:
This RTO Task Group reviewed the requirements which regular flight and maneuvering will put as design loads on the structure of future NATO aircraft, addressing also safety aspects, structural weight, elastic effects and influence of the control system. Treated are load critical flight maneuvers as well as external loads such as induced by turbulence. Existing specifications are reviewed and procedures for establishing design loads are presented. Metal and composite structures are treated, and the analysis pertains to main structures as well as critical subassemblies. Under operational aspects the monitoring of loads and of structural fatigue are treated and some actual failure cases are analysed. The request for NATO agreements on relevant design criteria is mentioned.
