The research hypothesis is that innovative design in the aerospace field is often done by a process similar to the method called Parameter Analysis. Case study research methodology is used to investigate five cases demonstrating the presence of Parameter Analysis characteristics in unique aerospace innovations. As the case study approach is not often used in engineering and in design research, much thought was given to building the research framework. Guidelines established for the research included criteria for case selection, data collection and analysis. Pattern matching was used to verify the hypothesis and conclude that Parameter Analysis is a design method suitable for practicing and teaching innovative aerospace conceptual design.
The case studies were an unusual looking asymmetric plane, a human powered air vehicle weighing 70 lb, the first vehicle to win the X-prize by going to space, a unique bomb developed during WWII and a contemporary unique solution for store release from an aircraft.
The research identified eight characteristics of Parameter Analysis as valid criteria for interpreting and analyzing the case studies: 3- step process, iterative nature, alternating spaces, parameter identification, constant evaluation, minimalistic configurations, use of basic physics and steepest development. In each case study, at least five characteristics were identified. Three characteristics were found to be dominant: parameter identification and 3-step process (demonstrated in all case studies), and basic physics (demonstrated in 4 of the 5 cases). Steepest development appeared in 3 out of the 5 cases.
