Kinematic Design and Analysis of a Morphing Wing
… optimize the flight characteristics of aircraft, wings must be designed for the specific mission an aircraft will see. An airplane rarely has one specific mission, and therefore is usually designed as a compromise to meet many flight objectives with a single wing surface. Large-scale shape change …

Structural Design and Analysis of a Kinematic Mechanism for a Morphing Hyper-Elliptic Cambered Span (HECS) Wing
The HECS wing was developed by NASA Langley Research Center and has a nonplanar, hyper-elliptically swept leading and trailing edge as well as spanwise camber. For this wing, the leading and trailing edges are swept back according to a hyper-elliptical equation. The span of the wing is also defined …
