Like an airplane, a hydrofoil experienced drag that slows it down. Figuring out how to reduce drag is the key to flying forever. We’ve done plenty of product review and have played around with different front wings, rear wings, mast lengths and fuselage lengths and we’ve found a setup that we really like, but we need to go deeper if we want to fly farther. We need to go back into the classroom, open some aerodynamics and physics textbooks to learn about flight, and how we can unlock longer human powered flight on a hydrofoil. Our current pumping record is 2.5 minutes, but we want to go further, and “pump“ the foil for longer. Source of Wingtip vortices from Wikipedia: Source of airfoil analysis:
