The most produced American military aircraft of World War II was not a small fighter, a trainer, or a simple utility airplane — it was a complex four-engine heavy bomber called the B-24 Liberator. Over the course of five years, American industry produced a staggering 18,482 of these bombers, and they served in every theater of the war.The B-24 was a workhorse with strategic impact, but it would not have had its utility — or possibly even existed — were it not for its wing.<br>Of course, all airplanes need a wing to fly. But the B-24 Liberator’s wing was special: an innovative oddity that enabled the B-24 to outperform the B-17 in speed, range, and useful load. It’s also a distinctly American story of defense innovation, in which a self-taught engineer saw something the credentialed experts missed, relentlessly pushed his innovation until it overcame skeptics, and found a company with a hard problem and enough ambition to risk capital on a technological advantage.<br>This is that story.

The Davis Wing<br>In the 1930s, Consolidated Aircraft was a flying-boat company producing PBY Catalinas and PB2Y Coronados with an inherent engineering challenge: Flying boats needed to unstick from the water efficiently while also maximizing flight performance, which required a wing that generated considerable lift at low angles of attack.<br>In 1937, Texas freelancer David R. Davis approached Consolidated with a revolutionary wing design that promised greater efficiency than any other wing in existence, with attributes that would solve the flying boat problem.<br>Unlike all wings of the time, the so-called Davis wing was based on intuition, keen observation, and empirical evidence. Davis got his idea from watching falling water droplets. As the drops fell, he observed that they assumed the natural aerodynamic form of a teardrop. Starting with a perfect teardrop-shaped airfoil, Davis continually tweaked it until it produced lift, characterized it with a formula, and then refined it to maximize lift. In 1934, he was granted a patent for this “fluid foil,” claiming that this thick, low-drag airfoil could support a long, high-aspect-ratio wing that was highly efficient. Potentially. To prove it, the wing had to be built, and that was a problem.<br>As a freelancer, Davis had no resources to build a full-scale wing, let alone an airplane, so he needed an aircraft builder. But the idea faced heavy skepticism from every institution he approached for several reasons. Davis was a self-taught self-titled “practical engineer,” not a credentialed aerodynamist. He also guarded the formula and coefficients behind his patented wing, fearing they would be stolen before he could profit from them. That made his claim hard to evaluate: He was asking an airplane manufacturer to trust a shape whose performance he would not fully disclose.<br>Furthermore, educated engineers could not discern a scientific basis for why the unusual airfoil would perform as empirically claimed. A federal research institution, the National Advisory Committee on Aeronautics, had already charted the orderly path to advance the aviation industry. They had recently wind-tunnel-tested, characterized, and cataloged 78 proven airfoils for engineers to use to help them build better-performing aircraft. Davis had brought an empirical invention to Consolidated, and it looked nothing like any of the open-source industry standards that had already been rigorously evaluated by the premier aeronautical engineering body in the country.<br>After some deliberation, in September 1937, Consolidated Aircraft decided to fund a subscale wind-tunnel test to assess the Davis wing, and the results were so good that the test was thought to be a fluke or a calibration error. Consolidated was interested but still not committed. When a new high-fidelity wind tunnel opened in August 1938, the tests were repeated side by side using a comparable-sized traditional airfoil. The Davis wing showed 20 percent better performance, and Consolidated committed to funding a full-scale flying demonstrator.<br>The wing was incorporated into the XP4Y-1 Corregidor prototype, a proposed flying boat successor to the company’s PBY Catalina. The improved...
