The development of better helicopters and all other types of rotorcraft, needs us to master the subject of aeromechanics to a much higher level than we are at now, and we must strive to acquire a true predictive capability for the physics that are free of modeling contradictions. It is argued that we have reached a transition phase, with a 'dip' in the progress of furthering the capabilities of all rotorcraft concepts. In this context, a dip is considered mostly to be the zone between having some understanding of a physical problem but still an essentially postdictive capability, and mastering the problem by having a real understanding and gaining a true predictive capability with high confidence levels. Getting through the dip requires an invigorated investment in advanced rotorcraft research and the development of new technical skills. This means that we cannot continue to do the same types of research that we have been doing during the last few decades, and so continuing to root ourselves in a comfort zone of only tentative or 'calibrated' understanding. To efficiently get over the dip, we must also eliminate everything that is not aligned with the authentic purpose of improving the understanding of all types of rotorcraft and their component systems. Our overarching objective is to make good design decisions based on validated models of aeromechanics that have quantified predictive capabilities. To this end, we must master the necessary understanding by using any and all of the tools available to us, including theory, numerical models, and the best types of experiments we can possibly devise, including laboratory experiments, wind tunnel testing, and flight tests. Focusing today on establishing the best principles on how to cross this dip will help us foster the most efficacious new research activities that will have the quickest and highest technical payoffs for the future.
