Orville and Wilbur Wright in 1904

Who was the engineer?

Although the Wright brothers shared credit for all their work, their remarkable partnership was built on their often complementary talents. Wilbur often took the lead in aerodynamic theory and design, while Orville contributed many of their elegant mechanical solutions. In engine design, Orville clearly the innovator.

The brothers' work on the engines began as a joint project, with significant contributions from their talented machinist, Charley Taylor. As the demands for engine performance increased, Orville took on the task of improving their design. Wilbur acknowledged his brothers' ability, and continued to experiment with Engine No. 3 as Orville pressed ahead, developing the Vertical Four engine in 1906.

Orville's new engine was the primary powerplant for their aircraft for the next ten years. Although he was the engineer, the true success of the engine lay in the fact that he had a clear understanding of its requirements. It was only a part of the overall aircraft design, which relied on Wilbur's contributions in other areas.
