Abstract
This presentation explores the concept, fundamentals, and mechanics of dynamically aerocompliant wings including a system on how to implement this on real aircraft and the benefits gained. Dynamically aerocompliant wings greatly enhance the safety and comfort of passengers and crew in an aircraft by mitigating the effects of air disturbances. Air disturbances, including but not limited to turbulence and wake vortices, can cause minor vibrations of the aircraft up to extreme upsets that can take down an aircraft. Minimizing the effects of these disturbances can be done by changing the camber across the wings similar to what bird feathers do. Feathers flex individually across a bird's wingspan to adapt to uneven gusts to maintain a constant lift. Technology exists that can mimic this on aircraft, and it has been studied for over 15 years, this system is called Pressure Adaptive Honeycomb (PAH). Analysis of this system from implementing it on a sailplane design showed that the aircraft could handle much stronger air disturbances and greatly improve ride quality. Additional benefits from the implementation of PAH include weight savings and cost effectiveness.
