Bypass engine with means for limiting gas leakage

Year	Description
1997	Invention patented by Xavier Jean-Mich Andre Guyonnet and Pascal Claude Wurniesky on April 9th, 1997. Abstract: A bypass engine including a fan which has its blades disposed in both the imary gas flow path and the secondary gas flow path of the engine is provided with an annular intermediate gas flow path in the space between the primary and secondary flow paths, and gas take-off means is connected to a compressor of the engine and arranged to direct a flow of gas longitudinally along the intermediate flow path to prevent leakage of hot gas to the secondary flow path via the gaps existing between the platforms of the fan blades and the adjacent annular members of the primary and secondary flow paths.
