Discussion
Match each term in List I with its definition in List II.
List I
A. Sideslip angle
B. Fin volume ratio
C. Sidewash
D. Rudder lock
List II
1. Angle between the relative wind and the plane of symmetry
2. Fin area times arm over wing area and span
3. Lateral flow deflection altering the fin's local sideslip
4. The surface floating hard over after a fin stall
Select the correct match.
Answer: A
Correct answer: A-1, B-2, C-3, D-4
Sideslip angle is the angle between the relative wind and the plane of symmetry. Fin volume ratio is \( S_f l_f / (S b) \) - fin area times arm, over wing area times span - the non-dimensional measure of how much fin an aeroplane has.
Sidewash is the lateral flow deflection that alters the fin's local sideslip, reducing its contribution below what geometry alone would give. Rudder lock is the surface floating hard over after a fin stall reverses its hinge moment. The first three are quantities; the fourth is a failure condition, which is enough to place it.
