Disclosed are propulsion systems 30 providing reduced fuel burn, weight and cost. A single gas generator core 38 drives multiple bladed propulsion elements 36 with a power train 48. The core 38 has a forward compressor 56 and a rearward turbine 40 and rotates about a longitudinal core axis 62. The bladed propulsion elements 36 rotate about bladed propulsion element axes 78 that are not coaxial with the core axis 62. The bladed propulsion elements 36 discharge an ambient air stream 50 rearward as a bypass stream 52 portion and a core stream 54 portion. Th...
What is claimed is: 1. A propulsion system comprising: a gas generator core including a forward compressor and a rearward turbine joined by a primary shaft rotational about a longitudinal core axis, the shaft projecting forward of the compressor; a power train having a primary gearbox and multiple secondary gearboxes, where the primary gearbox is driven by the primary shaft and driving multiple drive shafts and each secondary gearbox is driven by a drive shaft and driving a fan, where the power train is driven by said primary shaft and driving multiple ...
