Which aviation pioneer developed wings with a front and rear spar and connecting ribs?

The aviation pioneer known for developing wings with a front and rear spar and connecting ribs is John Stringfellow. His contributions were significant during the early stages of aviation, particularly in the use of structures to support wing loads and improve aerodynamic performance. Stringfellow's designs incorporated the concept of using a framework that allowed for greater strength and rigidity in the wing structure. The front and rear spars provided support along the length of the wing, while the ribs formed the shape and structure, creating an airfoil that could generate lift.

This method was an important advancement in wing design, influencing future aircraft construction. The concepts behind using spars and ribs are fundamental principles in aerodynamics and aircraft engineering, still visible in modern aircraft designs. Understanding the contributions of pioneers like John Stringfellow can help appreciate the evolution of aeronautical engineering and the intricate designs that enable flight.
