Lift is a phenomenon whereby a uniform flow in one direction produces a component of force on an obstacle in a perpendicular direction. Aeroplane wings and automobile spoilers are examples of cambered ...

Even in 1800, it was understood—by at least one person, a certain George Cayley—that two forces, weight and drag, were antagonistic to flight and that there must be two corresponding forces to ...

Light has been put to work generating the same force that makes airplanes fly, a study appearing online December 5 in Nature Photonics shows. With the right design, a uniform stream of light has ...

There are many ways to describe the forces around sails — in fact, around any foil. One of the most straightforward ways is to split the forces into lift and drag. The lift force is, by definition, ...

LIFT Aircraft Co. has been awarded a U.S. Air Force contract to continue experimentation and flight test efforts around its HEXA copter. LIFT Aircraft Co. has been awarded a Phase 3 contract through ...

Without the aerodynamic forces of lift and drag, aircraft would be unable to fly, wind turbines would not spin, and countless other machines that we depend on every day would not work. What, exactly, ...

Introduction Not even the strongest human could lift a truck into the air. Our brains, however, are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! You can find them ...
