Abstract
In today's business climate, aerospace companies
are more than ever in need of rational methods and
techniques that provide insights as to the best
strategies which may be pursued for increased
profitability and risk mitigation. However, the use of subjective, anecdotal decision-making remains prevalent due to the absence of analytical methods capable of capturing and forecasting future needs.
Negotiations between airframe and engine
manufacturers could benefit greatly from a
structured environment that facilitates efficient,
rational, decision-making. Creation of such an
environment can be developed through a parametric
physics-based, stochastic formulation that uses
Response Surface Equations as meta-models to
expedite the process. This paper describes the
implementation of such an approach in order to
demonstrate the types of insights that might be
gained as an engine manufacturer tries to forecast
the effects of the associated airframe uncertainties (structural, aerodynamic, etc. design changes) on engine related characteristics for the design of a hypothetical regional business jet.
