摘要

Aerobatics I'D Heard Of. But "hydrobatics"? I cinched my five-point safety harness tighter. Looking out from inside a Plexi-glas bubble, I could see the choppy waters of California's Monterey Bay. Waves smacked against our sub's stubby wings. Seated just ahead of me, his head inside a second bubble, sat Graham Hawkes, the craft's creator and pilot. "Ready to dive?" he asked. The tempo of the twin electric thrusters increased. We submerged. The craft's nose dropped 30 degrees, and I tipped forward in my seat, happy for the safety harness' restraint. Below us lay a vault as vast and welcoming as the sky's. We gained speed, soaring, banking―flying. Hawkes means "flying" literally, not as metaphor. Mechanical linkages connect the joysticks and rudder pedals to external surfaces that control pitch, roll and heading. The same physics apply to vehicles immersed in air and water, allowing for different values of mass and viscosity. Deep Flight Aviator's wings, viewed in cross section, look exactly like an airplane's, upside-down: They're curved on the bottom, flat on top. As the craft moves forward, the flow of water over the curved side pulls the wing downward Cut the engines and Deep Flight Aviator floats back to the surface. Just as in a plane, you can stall if you assume too steep an angle of attack. Hawkes, to his chagrin, has stalled several times. No one yet has done a loop-the-loop, but Hawkes thinks such maneuvers will come soon, as hydrobatic pilots gain experience and confidence.
