Preliminary ConceptsPreliminary Concepts Flying wingFlying wing
– Fuselage is built into wing, cuts down on air Fuselage is built into wing, cuts down on air resistanceresistance
– Reduces material required for fuselageReduces material required for fuselage– May be difficult to support/brace payload bay properlyMay be difficult to support/brace payload bay properly
BiplaneBiplane– Larger wing surface areaLarger wing surface area– Increase in liftIncrease in lift– Not enough engine power suppliedNot enough engine power supplied
