Need a lift?

  If you ever want to convince someone that flying is magical, just remind them that scientists still can’t explain exactly how a wing produces lift. Theories abound. For a long time it was all thanks to Daniel Bernoulli and the idea that an airfoil accelerates the airflow, which means it must lose pressure perpendicular to the wings, thereby sucking you, your airplane and your credit cards … Continue reading Need a lift?

A.W.52

  All this talk of future commercial airplanes rings with echoes of the past. Of course the 1940s’ Horten and Northrop flying wings are well known. But Britain was pushing on the technological ceiling at the same time – with their Armstrong Whitworth A.W.52. A grand vision While not a true flying wing (it had vertical surfaces at each wing tip for yaw control) the A.W.52 was … Continue reading A.W.52

Airline futures

  An avweb flash entitled Smaller Aircraft Tails Possible caught my eye back on December 5th. It linked to a story from CalTech, called Sweeping Surfaces for Greener Planes – relating how researchers at that eminent institution hope to reduce tail sizes (and weight, and drag, and fuel consumption) by using active flow control air to supplement the authority of a smaller rudder at low airspeeds. Changing the … Continue reading Airline futures
