  • Leading edge snag for exposed propeller engine installation
    Patent number: 8740139
    Abstract: An airplane powered by exposed propeller engines has a swept wing configuration comprising a leading edge snag coincident with the exposed propeller engine mount. The portion of the leading edge disposed inboard of the exposed propeller engine is offset in an aftwise direction relative to the outboard portion of the leading edge. As a result of this construction, the point of closest approach of the blades of the exposed propeller engines is moved aft, allowing for a more compact engine installation.
