Fuel Consumption Due to Shaft Power Off-takes from The Engine
2013 (English)In: Proceedings of the 4th International Workshop on Aircraft System Technologies / [ed] Frank Thielecke, Aachen: Shaker Verlag, 2013, 169-179 p.Conference paper (Other academic)
This paper looks at fuel consumption due to shaft power off-takes from the engine and the related increase in the aircraft’s fuel consumption. It presents a review and comparison of published and unpublished data on this kind of consumption. The paper presents results from the TURBOMATCH engine simulation model, calibrated to real world engine data. A generic equation is derived for the calculation of fuel consumption due to shaft power extraction. Main result is the shaft power factor kP found to be in the order of 0.002 N/W for a typical cruise flight. This yields an amazingly high efficiency for power generation by shaft power extraction from a turbo fan engine of more than 70 %.
