The Kappel propeller design concept promotes the inclusion of a "forward facing" blade tip winglet with the objective that propeller efficiency may be improved. Design development has enabled a series of finite element investigations in order to establish how the inclusion of an unconventional blade tip geometry might influence blade structural response. The paper reports on these investigation in which a thick shell finite element approach is utilised. The submitted results serve to demonstrate an unexpected blade response characteristic.
