Description
Technical Field
The utility model belongs to the technical field of aircraft structural design, concretely relates to control surface of light aircraft based on VARI forming technology.
Background
The control surface refers to an aerodynamic airfoil surface which generates an aircraft balance force and a control force by utilizing deflection in airflow to control the aircraft to fly, and the aerodynamic airfoil surface is also called as a control surface. The control surface is the control surface of the airplane and generally has three directions, and the traditional light airplane control surface is simply divided into three parts, namely a foam interlayer upper skin and a foam interlayer lower skin which form the appearance; ribs for transferring aerodynamic loads to the joint. The aircraft control surface bears the pressure of air pressure during the operation of the aircraft, so the stability of the aircraft control surface directly influences the operation safety of the light aircraft.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, the present invention provides a control surface of a light aircraft based on the VARI forming technology, the control surface includes an upper skin 1 and a lower skin 2, the upper skin 1 is inclined upwards; the left side edge of the upper skin 1 is glued with the left side edge of the lower skin 2, the right side of the upper skin 1 is provided with a downward bent part structure 3 with a radian, the right side of the corresponding lower skin 2 is provided with an upward bent part structure 3 with a radian, and the two bent part structures 3 are mutually matched and connected; a cavity is formed between the upper skin and the lower skin, a plurality of supporting rib groups are arranged in the cavity, and a wave-shaped supporting piece 4 is arranged between every two adjacent supporting rib groups.
Further, the upper skin 1 and the lower skin 2 form an acute angle inclination, and the inclination angle is 15-30 degrees.
Further, the wave crests of the wave supports 4 between adjacent support rib groups abut against the upper skin 1 and the wave troughs abut against the lower skin 2, the wave supports decreasing in wave trough from the right.
Further, each support rib group consists of two approximately C-shaped support pieces 5 which are arranged in a back-to-back fit mode, and a gap is formed between the two approximately C-shaped support pieces 5.
Further, a foam interlayer 6 is arranged between the two C-shaped supporting pieces 5.
The utility model has the advantages that: simple structure through being equipped with wave form support piece between adjacent support rib group, can be fine play to the supporting role of upper and lower covering, increase the safe life of aircraft, and this support wave form shaping is simple, and the integrated design, the effectual flight quality that alleviates the aircraft has improved the steadiness of light aircraft control surface simultaneously.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, the utility model provides a control surface of a light aircraft based on VARI forming technology, which comprises an upper skin 1 and a lower skin 2, wherein the upper skin 1 inclines upwards; the left side edge of the upper skin 1 is glued with the left side edge of the lower skin 2, the right side of the upper skin 1 is provided with a downward bent part structure 3 with a radian, the right side of the corresponding lower skin 2 is provided with an upward bent part structure 3 with a radian, and the two bent part structures 3 are mutually matched and connected; a cavity is formed between the upper skin and the lower skin, a plurality of supporting rib groups are arranged in the cavity, and a wave-shaped supporting piece 4 is arranged between every two adjacent supporting rib groups. The upper skin 1 and the lower skin 2 form an acute angle inclination, which is 15-30 degrees. The wave crest of the wave-shaped supporting piece 4 between the adjacent supporting rib groups is abutted against the upper skin 1, the wave trough is abutted against the lower skin 2, and the wave-shaped supporting piece is sequentially reduced from the right side by the wave trough. Every support rib group comprises two approximate C shape support piece 5 that the laminating set up dorsad, has the space between two C shape support piece 5, is equipped with foam interlayer 6 between two C shape support piece 5, increases foam interlayer for two C shape support piece 5 and lower covering better realize the integrated into one piece based on the mould for convenience.
The working principle is as follows: based on VARI, vacuum resin is introduced, the lower skin and the support rib groups are integrally formed, and the upper skin and the wave-shaped support are integrally formed through vacuum resin introduction. Subsequently, the upper and lower skins are brought together, i.e. the left and right sides are fixed by bonding, respectively, to achieve the fixation, and the upper and lower skins form a closed cavity, wherein the corrugated support member is located between the two support rib groups. Adopt the utility model discloses a control surface structure, wherein adopt the fashioned wave form support piece of integration liquid can be fine play the firm effect of support to upper and lower covering between the upper and lower covering, the integration shaping can be fine the improvement light aircraft random steadiness, prevent to set up a plurality of support piece and support, the wholeness can be poor.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
