Akaflieg München Mü28
Use of a symmetrical aerofoil section and an innovative automatic flap system (Wölbklappenautomatik) contributed to the Mü28's success. By combining a symmetrical aerofoil section with an automatic flap system the Mü28 has identical performance and handling in normal and inverted flight wikipedia.org

SZD-7 Osa
Development The SZD-7 or IS-7 Osa (Wasp) was based on the IS-2 Mucha, with a laminar flow aerofoil section developed by Tadeusz Kostia. Little information on laminar flow aerofoils was available but Kostia was able to design the aerofoil for the SZD-7 Osa to achieve laminar flow to at least wikipedia.org

(PDF) Optimal Design Method for Wind Turbine Blades Considering ...
Most traditional methods for optimizing the blade design have no consideration on the aerofoils of cross-section, which makes the blade design difficult to achieve the optimal solution.

Zero-lift axis
A cambered aerofoil generates no lift when it is moving parallel to an axis called the zero-lift axis (or the zero-lift line.) When symmetric aerofoils are moving parallel to the chord line of the aerofoil, zero lift is generated. wikipedia.org
