Sammanfattning
The following report covers the methodology behind creating an off-design model for
an existing notional propfan engine model in NPSS. Particular attention has been
given to; the creation and implementation of a custom propeller element together
with the relevant performance maps, ensuring operability throughout the flight en velope, proposition of thrust ratings and their accompanying scheduling strategies as
well as performing whole mission envelope simulations in NPSS in order to quickly
evaluate a notional engine throughout its range of operations. From this a recom mendation for how a future propfan engine could be controlled has been given along
with some observations and conclusions on SFC, bleed work and operability.
