Almost, but not quite AFAICS. Yechout describes on pg41 in fig 1.46 a period where lift decreases, but that is not then related to the CM effect which is exhibited as tuck. Yechout describes an oblique shock formation, which occurs when the section has a free stream velocity of M1.0, whereas the section shows a lower surface normal shock, below M1.0 free stream, but well after the upper surface normal shock commences at the sections Mcrit. The lower shock doesn't commence at the trailing edge as Yechout describes.
Thanks for the response however.
Centaurus, thanks for the Vamp info. That was a major pain on the Vampire in it's early days, was covered in some detail by Eric Brown, (along with landing the Vampire without wheels on carriers). The Vamp is running around Reno showing all of us its exhaust which is a bit embarrassing. They are on the edge of marginal longitudinal stability there.
