Do you have a reliable source for the center of lift behind CoG shift? I've not seen that claim before.
- Tostino 7y agoNot op and on mobile, but I have seen the CoG shift mentioned in threads and articles before on this topic. Would love a source to confirm my memory though.
- Tempest1981 7y agoThis doesn't mention CoG, but it mentions "dynamic instability": https://spectrum.ieee.org/aerospace/aviation/how-the-boeing-737-max-disaster-looks-to-a-software-developer https://spectrum.ieee.org/aerospace/aviation/how-the-boeing-... In the 737 Max, the engine nacelles themselves can, at high angles of attack, work as a wing and produce lift. And the lift they produce is well ahead of the wing’s center of lift, meaning the nacelles will cause the 737 Max at a high angle of attack to go to a higher angle of attack. This is aerodynamic malpractice of the worst kind.
- foldr 7y agoYes, that doesn't claim that the center of lift shifts ahead of the CoG. Nor is it a reliable source.
