One concept to reduce an aircraft's fuel consumption is to increase wing aspect ratio, i.e. the ratio of wing span to wing chord. Although slender (i. e. high aspect ratio) wings have low induced drag ...

In that equation b2 denotes the square of the wing span and F is the wing area. Consequently, increasing the aspect ratio requires a slender wing. Gliders, for example, have very high glide ratios (up ...

The use of ranked wingtips would have increased the A380's wings and would have forced engineers to decrease the overall size ...

The current U-2S runs on a General Electric F118 turbofan. Lockheed Martin describes the Dragon Lady as “ an agile and ...
