Dragonwing is a variable geometry aircraft designed to provide the versatility and access of a helicopter, with the range and and endurance of a fixed wing aircraft. I cannot, at this time, recommend this configuration for a realistic aircraft. Putting the rotor under the vehicle causes more problems than it solves. The purpose at the time was to demonstrate an ability to solve unique technical challenges with a solution that at least looks functionally integrated and aesthetically coordinated. The outcome of that exercise was very rewarding. For example, creating the geometry of the wing root was particularly challenging, but it has come in handy on other projects.

In estimating the performance of an aircraft with unique features, it is useful to show it on a chart with other aircraft with similar mission sets, if not similar technology. This is useful not just explaining the vehicle in context, but it improves the integrity of the performance estimates, and provides a good starting point for conversing with others who understand the topic very well. The other advantage to compiling and showing those comparisons, is it can be used for understanding and designing other aircraft that perform similar missions.
