Bjorn’s Corner: Aircraft drag reduction, Part 21
March 16, 2018, ©. Leeham News: In the last Corner, we looked at the drag of an airliner during cruise. We could see the thrust required to counter the drag in the thin air of 37,000 feet was low,… Read More
Bjorn’s Corner: Aircraft drag reduction, Part 20
March 9, 2018, ©. Leeham Co: In the last Corner, we started to go through a typical mission for an airliner and study which drag types are important when and why. We went through the take-off and climb phases,… Read More
Bjorn’s Corner: Aircraft drag reduction, Part 19
February 23, 2018, ©. Leeham Co: In the last Corner we wrapped up the discussion on different drag types by discussing some less dominant drags. To finish the series we will go through a typical mission for an airliner… Read More
Bjorn’s Corner: Aircraft drag reduction, Part 6
November 24, 2017, ©. Leeham Co: In the last Corner, we described how the Wright Brothers obtained the aerodynamic data they needed to design gliders and aircraft. But there was additional knowledge they needed: how to control an aircraft… Read More
Bjorn’s Corner: Aircraft drag reduction, Part 2
October 27, 2017, ©. Leeham Co: After a detour over Airbus’ A330neo first flight last Friday, we now continue with aircraft drag. We divided drag in two classes last time: drag from size and drag from weight. These drag… Read More
Bjorn’s Corner: Aircraft drag reduction
October 06, 2017, ©. Leeham Co: In the last several Corners, we wrote about research around laminar flow for aircraft. It’s research to lower the aircraft’s drag. Why is this important? How large are the different drag types and… Read More
