The striking differences between the experimental data in incipient and deep stall conditions make the level of uncertainty of this kind of experimental measures clearly understandable.

As is known from literature [35], the 3D coefficients are much higher than the 2D values even in deep stall conditions.

The report said the plane went into a "prolonged stall condition that was beyond the capability of the crew to recover".

Higher twist resulted in near stall condition and drastic fall in the power coefficients.

The results reveal that entropy generation seems to give an advantageous effect of reducing the separation at the tip section of the VTB in the deep stall condition.

In this paper, principles that guarantee the similitude of the flow field at near stall condition and the effectiveness of the casing treatment are discussed.
