Abstract: An ultra high bypass ratio turbofan engine includes a variable pitch fan, a low pressure turbine, a reduction gearbox, and a plurality of outlet guide vanes. The ultra high bypass ratio turbofan engine has a bypass ratio between about 18 and about 40. The variable pitch fan and the low pressure turbine are coupled together by the reduction gearbox. The reduction gearbox reduces the speed of the variable pitch fan relative to the low pressure turbine. The plurality of outlet guide vanes are spaced aft of the variable pitch fan and are axially swept. The variable pitch fan and the low pressure turbine are configured to generate a fan pressure ratio between about 1.15 and about 1.24.

Abstract: A supersonic aircraft engine axial fan that includes a rotating blade row having blades that receive a supersonic entry flow in the absolute frame and decelerate the flow to a lower supersonic or subsonic velocity exit flow while adding work to the flow to increase stagnation pressure. It is preferred that the lower velocity be subsonic. When the fan is combined with a suitably designed inlet, the propulsion system is compact and lighter in weight than conventional engines for supersonic aircraft.

Abstract: The invention relates to a turbofan aircraft engine comprising a central mechanism mounted in a gondola and a fan which feeds a mixer with cold air passing through a secondary flow channel. A low-pressure turbine cone is located in the mixer where the hot air flow which emerges from the low-pressure turbine cone of the central mechanism is mixed with the cold air flow. Part of the cold air flow for the low-pressure turbine casing reaches an annular slot located between the casing and a lining encompassing said casing. Another part of the cold air flow is guided through the hollow outlet guide vanes of a following guide wheel towards the rear annular slot between the rotor and the stator of the low-pressure turbine, whilst the majority of the cold air flow reaches the ejector. The inventive turbofan aircraft engine is characterised in that the majority of the cold air flow passes through the hollow guide vanes before reaching the interior space of the low-pressure turbine cone, said cone having a downstream free end section with a nozzle type outlet opening, so that this downstream free end section acts as an ejector which adds the cold air flow to the air flow emerging from the mixer.

Abstract: An airfoil for a turbine engine includes pressure and suction sides that extend in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip. The airfoil has a relationship between a total chord length and a span position and corresponds to a curve that has an increasing total chord length from the 0% span position to a first peak. The first peak occurs in the range of 45-65% span position, and the curve either remains generally constant or has a decreasing total chord length from the first peak to the 100% span position. The total chord length is at the 0% span position in the range of 8.2-10.5 inches (20.8-26.7 cm).
