During the course of his research, Mr. Hamilton realized the potential of future composite materials in aircraft design. Hamilton now set upon a course of development, different from other designers. Hamilton AeroSpace began designing aircraft anticipating future advances in composite materials and engine design. The technique of designing for the come, probably resulted from his bird hunting experience. He knew if he wanted to hit the target, he had to lead it, and know that the desired interception, would take place.
Over the next several years, Hamilton Aerospace engaged in the development of composite design technology. Thousand of man hours were spent building parts and completing airframe assemblies. These parts and assemblies were subjected to all degrees of testing, including complete destructive failure testing. A significant data base was compiled on different laminates, resins, and core materials. This data base would be continually updated based on new material developments.
Having thoroughly researched composite materials, Hamilton AeroSpace was now ready to study the concepts of production that would benefit not only the military but, again, general aviation. The first focus was mass production. Could an aircraft be mass produced, so that costs could be spread over a greater number of units? Why did parts, for conventionally produced aircraft, have to be custom tailored at assembly time,? The second focus was design simplicity. How could the complexity of an aircraft be reduced for both military and general aviation designs? Could the same, or a similar airframe structure, with less costly materials, be used for less demanding general aviation designs?
With these goals in mind, Hamilton AeroSpace finalized the design, and began to develop tooling for, what is known as the A-II, Avenger tactical attack fighter. The design of this advanced aircraft introduces new concepts of production that greatly reduces the number of parts, thus lowering manufacturing costs. (The fuselage, for example, is cast in two sections, an upper and a lower) The exacting specifications of the tooling and the advanced composite materials, allows all parts to be interchangeable. This allows a wing section to be used on any fuselage section, without custom fitting. Wing sections, as well as other major subsections, are detachable for replacement, even under battlefield conditions. Keeping the aircraft in the air, is basic to the economics of the battlefield. Availability, the combination of reliability and maintainability, is inherent in the A-II.
The general aviation, Hamilton AeroSpace HX-322, is an outgrowth of the A-II design.
