Bjorn’s Corner: Aircraft lift, Part 3
April 06, 2018, ©. Leeham News: In the last Corner, we discussed the pressure distribution of an aircraft’s wing when producing lift. This was with a conventional airfoil (though of the more laminar flow type). Now we continue by… Read More
Bjorn’s Corner: Aircraft lift
March 23, 2018, ©. Leeham News: In the last Corner, we finished our series about aircraft drag, by studying an airliner flying a mission and noting how the drag changed. Before we leave the subject of airliner aerodynamics, we… Read More
