Bypass jet engine for aircraft is constructed such that at least a part of bypass or cold flow is located between inside diameter of base engine and surface or limits of central shaft housing

摘要

The bypass jet engine comprises a base engine constructed as a cylindrical component installed inside a casing with a gap between the inside and outside diameters in such a way that at least a part of the bypass or cold flow is located between the inside diameter of the base engine and surface or limits (18) of the central shaft housing, while the blade carriers of the compressor (2a,2b) or turbine blade ring of the core engine are connected to the associated centrally mounted shaft (15a,15b) by radially extending connecting elements which are especially constructed in spoke form and aerodynamically optimized and may be as secondary fan blades (7-7c).
