Summary The need to definitively determine dynamic stall onset events motivates us to primarily identify precursors to the phenomenon. Surface pressure measurements using advanced solid state sensor technology offers the best solution here. It is hypothesized that if the rapidly evolving leading edge adverse pressure gradient can be reliably quantified at dynamic stall onset, then the research results may enable successful development of active control sensor technology that can be integrated into flight systems to avoid dynamic stall totally or to develop a new control method.
