1 The valve is driven directly by a large strake multilayer piezoelectric stack, its displacement actuates the power cascade spool after amplification by a lever mechanism.

2 Pressure and velocity fields of spatial cross section on an aircraft model with strake wing and double vertical tails were measured using a seven hole probe.

3 The F-15's connection is outboard of the left engine inlet in the upper body of the wing root strake.

4 An experimental study of the effects of the twin vertical fins position and twist strake wing on a fighter aerodynamic characteristics was performed in the wind tunnel.

5 The required control forces and moments can be obtained using strake control techniques.

6 Some measures improving the longitudinal and lateral stabilities of aircraft with strake wing configuration are discussed.

7 Experiments show that the adaptability of the self-organized fuzzy controller works very well in different work condition,[] and can realize variable cushioning strake.

8 At last, all technologies in this paper are proved practical and doable by an example of train wheel strake.

9 A safe and feasible construction scheme is put forward for ship strengthened by doubler strake and its later repair.

10 Some measures improving the longitudinal and lateral stabilities of combat aircraft with strake wing configuration are discussed.

11 Some unusual control surfaces such as spoiler, clam-shell aileron, body-nose strake, movable wing-tip are investigated on two typical configurations.

12 The maximum lift coefficient could be raised by 30%. It has been shown that moving surface is an excellent technique to control separated flow over the strake wing.
