Conceptual Aircraft Design Exploration through Functional Approach [PDF]
Applied Mechanics and Materials, 2013 In today’s market, it is no longer sufficient to have better designs than the competition. In order to maximize the product’s market potential, it has to be rapidly produced and made available to the market. To reduce their time-to-market period, manufacturers need to shorten their design and development process.
