Adolf Busemann, a student of Ludwig Prandtl, introduced the concept of wing sweep to delay shock formation, enabling aircraft to reach much higher speeds. His research on wing sweep would be conducted during World War 2 at the LFA-Braunschweig wind tunnels whose facility and any research records have since been either been lost, confiscated by the Allies, or destroyed. Fragments of Busemann’s work endure by other notable individuals such as R.T. Jones, Dietrich Küchemann, Harry Murray as well as Alexander Lippisch and Walter Beuschausen. The following serves as a recreation of one of Busemann’s Wind Tunnel Tests using ANSYS Fluent, exploring the importance of drag divergence, wing criticality and its implications on modern wing design. This discussion is followed by a novel concept of leading edge tubercles, which has gained the attention of many to serve as a high-lift flow-control mechanism. Originally inspired by humpback whales, computational and wind tunnel studies indicate significant influences in post-stall regime, however little is discussed in terms of shock formation and wing criticality. The discussion of Busemann’s work will serve as bridge to connect what has been learned to shed light in a seemingly uncharted territory.
