Stability and Control characteristics of the Early Mark Spitfires

Right....

Edge of the Buffet is not IN the buffet.




If you have no other guide, the buzz is useful for finding CLmax. Don't fly in the nibble but back off to just before though IF you want maximum turn performance.

Lift varies with angle of attack and airspeed. The highest useful angle of attack is just before the critical angle, about 15 degrees. At this high angle of attack, maximum CL, considerable drag is produced, and if the aeroplane stalls, or the buffet is reached, the drag will increase dramatically. Ideally, sufficient backpressure should be applied to activate the stall warning (if it is operating) on its first note. Alternatively, the very edge of the buffet will need to be used as a guide to maximum CL.

You can fly in the nibble if you want, IvanK. However somebody that is turning in the same airplane at the point of smooth air just before the nibble will out turn you. That is how the physics works.

Its not a case of not "wanting" to be in the situation... Operational pilots often find themselves in situations they dont want to be in. The question put was quite specific, a Spitfire MKI no AOA gauges no accelerometers just you the pilot and your basic airframe.

Right.....Again, I would not want to be in that situation with a neutral or unstable aircraft with a light stick force per G and extremely small amount of available stick control.

That why we see charge sheets with "structural failure" and "wings came off in aerobatic flight".

But you did say that Cambridge and others used the Spitfire wing when you clearly don't know

Making up what????

Start another thread on this off topic sideshow. Cambridge awards degrees, they published the book, and it is used as a reference in many engineering curriculuums.

If you don't like those facts, tell Cambridge not me.
