Refinements of Powerplant
• More accurate engine data
– Mass data:
– Size data:
– Performance data: Variation of thrust and fuel consumption as
function of flight speed, altitude and engine setting
• How to get the data
– From the engine manufactures
– Using the more precise model of the engine based the engine
design method
• Powerplant Location
– The development of the design concept now enables the question
of powerplant location to be considered more precisely.
