A propeller blade (10) includes an inner spar structure (16) surrounding an inner spar foam core (14). Also included is a leading edge foam structure (20) disposed proximate a leading edge of the inner spar structure (16). Further included is a trailing edge foam structure (22) disposed proximate a trailing edge of the inner spar structure (16). Yet further included is an outer spar structure (28) surrounding the inner spar structure (16), the leading edge foam structure (20) and the trailing edge foam structure (22). Also included is a blade shell (30), a leading edge foam core (32) located between the outer spar structure (28) and the blade shell (30), and a trailing edge foam core (34) located between the outer spar structure (28) and the blade shell (30). |
