ASTRID - aircraft on board systems sizing and trade-off analysis in initial design

Unlike the past, when the system view of the airplane was not at all evident and the results of the conceptual design were almost exclusively turned into the preliminary definition of the airplane main characteristics, today the systems engineering approach is widely accepted and appreciated and the results of the conceptual design include also initial basic choices for onboard systems. We can say that, as the proposed new approach guarantees more accurate and detailed definition of an aircraft concept and makes more effective the development process, ASTRID represents a real improvement of the tools available for Aircraft Conceptual Design
