- W2104986819 abstract "Abstract : Production models, Acceptance tests, Research management, Costs, Jet engine fuels, Refining, Technology, Regression analysis*Product improvement, *Technological change, *Cost reduction, *product development, MQT(Model Qualification Test), Model qualification test, Aircraft modificationAn area of R and D activity often as important as new product R and D is R and D directed at improving an existing object, often called product improvement. Multiple regression techniques were used to estimate a multi-dimensional technology tradeoff surface for U.S. aircraft turbine engines. Product-improvement engines embody a higher level of technology than their original versions, but the rate of technological advance is significantly less than the long-run average for new designs. Further, thrust-growth product improvement is subject to diminishing returns with respect to dollar resources. (Modified author abstract)" @default.
