These depend on many factors such as customer and manufacturer demand, safety protocols, physical and economic constraints etc. But in order for the industry to function as intended, companies must design new aircraft, typically using the three-stage process described here. A very typical approach to any product development is as shown in the diagram below: The design process for an aircraft can be seen as very similar to other engineering products. At the detail design stage, every single component will be designed from and tested. Hence a solution to this is to modify existing aircraft by upgrading some parts. © 2020 All rights Reserved. Engineers will also look for structural defects and flaws, correcting them before proceeding to the third and final stage of the design process. This is done by both explaining the process itself (Chapters 1 and 2) and by providing a variety of examples of actual student design projects (Chapters 3 to 10). These basic functions are brought together to create the initial configuration design which is used to discuss different possibilities with the consumer during a conceptual design review.
