Aircraft design is developing layout and configuration that meets customer specifications and airworthiness requirement.
Aircraft design process refers to configuration development, detail design, and product support phases involved in aircraft design.
Cost is the main driver of the 21st century aircraft design process.
The three stages of aircraft design consists the conceptual, preliminary and detailed design stages.
The radius of spiral suggests range of feasible choices, also, disciplinary balance is an essential asset to aircraft design specialists.
Simplicity gives affordability, elegance, reproducibility and speed to aircraft design projects.
Requirements capture entails identifying the features in the design that will give the highest customer satisfaction.
Customer attributes refers to the primary, secondary and tertiary requirements that describes customer characteristics.
The steps in making a House of Quality Chart are:
(i) List down customer needs.
(ii) Assign priorities to the needs.
(iii) Decide the design features to be provided to meet the requirement.
(iv) Fill-in the design features matrix.
(v) Calculate design priorities.
(vi) Rank the design features.
(vii) Repeat the whole process.
The clausing 4-level house of quality model consists: (i) House of Quality (ii) Parts deployment (iii) Process planning and (iv) Production planning.
The first level of the House of Quality Chart involves conversion of customer needs into performance parameters.
The Rough Order of Magnitude (ROM) Analysis: involves keeping all other HOWs constant and calculating the impact of each HOW on each WHAT.
