Using modular components as a basis for design, construction and continuous improvements of aircraft

In previous years, aircraft technology developed so rapidly that, like today's computers, aircraft became obsolete and were replaced at or before the end of their service life. However, the high cost of design, construction and testing of new platforms, combined with a lack of significant structural design advancements has created an era of "upgrades" as alternatives to replacement. Yet, the aircraft in service now were not designed for planned improvements. Thus, these improvements, which can be quite extensive, are generally costly.

Unless a most unlikely, but dramatic, change occurs, aircraft will continue to have thirty to fifty year service lives. Nevertheless, technology and government regulations will continue to change, requiring upgrades to existing platforms before the end of their service lives. Based on research of government and corporate concepts, this study proposes a plan for aircraft design, construction, integration and testing (verification) that promotes planned, cost effective upgrades over the aircraft's service life. This plan incorporates the concept of modular design. Finally, the superior benefits of lower cost, easier maintenance, and continuous improvements of aircraft, designed and constructed in modules, are discussed.
