36 Method and Software of Technical Risk Assessment for a Civil Aero-Engine Available to Purchase

The weights of specific technologies are obtained by using analytic hierarchy process and quality function development, which can partition the customer's aggregate demand for the advanced civil aero-engine layer by layer until specific technologies, the risk level of specific technologies are quantified according to their technology readiness levels. The overall technical risk of the aero-engine can be calculated by integrated analysis of weights and risk of specific technologies. This method can assess the aero-engine as well as its component system. Take the fan component of an under-researched turbofan-engine for example, the software incorporate the method yields the quantitative result.
