摘要:
The invention comprises varying the ratio between the control surface local chord (I) and the vertical stabilizer local chord (L) along the height of the vertical tail (2) in order to adapt the local value of the coefficient of the side lift applied to the vertical tail (2) to a maximum acceptable value of the side lift coefficient.

An adjustable, or all-moving, horizontal stabiliser for an aircraft, the stabiliser having a leading edge, a trailing edge, a root and a tip, and a strake fixed with respect to the stabiliser and attached to, or integrally formed with, the stabiliser leading edge adjacent the root.
摘要:
A method for improving the aerodynamic efficiency of the vertical tail of an aircraft includes varying the thickness of the trailing edge of the rudder as a function of the span of the vertical tail. This variation is intended to adapt the local value of the coefficient of lateral lift applied to the vertical tail closer to a maximum allowable value. The maximum allowable value is specifically the value at which a separation of the aerodynamic flow is observed on the surface of the vertical tail.

An endoscopic instrument has an external tube and a hollow cylinder coaxially extending along a longitudinal axis and actuatable to move axially in opposite directions to rotate a distal end of the instrument provided with an engaging element between angular positions. The distal end actuated by the outer tube is rotatable about a pin having an axis of rotation which is spaced radially from the longitudinal axis as another pin formed on and extending radially from the cylinder is guided along an arcuate groove provided on the distal end of the instrument.

摘要:
A method for enhancing aerodynamic efficiency of a vertical tail includes varying the ratio between the control surface local chord and the vertical stabilizer local chord along the height of the vertical tail. This variation is configured to adapt the local value of the coefficient of the side lift applied to the vertical tail to a maximum acceptable value of the side lift coefficient. As a result, the aerodynamic efficiency is maximized by applying a coefficient approaching the maximum acceptable side lift coefficient.

摘要:
According to the invention, the thickness (EP1) of the trailing edge (4) of the rudder (9) is varied as a function of the span (E) of the vertical tail (2) to adapt the local value of the coefficient of lateral lift applied to the vertical tail (2) to a maximum allowable value.
