Embodiment Construction

[0039] The purpose of the present invention is to provide a set of mechanisms for changing the length of the wings by stretching and retracting, and changing the curvature of the airfoil by retracting and retracting the flaps, so that the aircraft equipped with the wings can have good high-speed and low-speed performance. The detailed description is combined with the abstract drawings and Figure 1~6 illustrate.

[0040] The wing is a three-stage retractable wing mechanism, and each section of the wing includes a main wing and a flap. It specifically includes the inner main wing 1A; the outer main wing 3A; the middle main wing 2A nested between the inner main wing 1A and the outer main wing 3A; the inner flap 1B hinged with the inner main wing 1A; and the outer main wing 3A hinged The outer flap 3B of the outer section; the middle section flap 2B nested between the inner section flap 1B and the outer section flap 3B and hinged with the middle section main wing 2A; respectivel...

Abstract

The invention discloses a telescopic wing mechanism with slotted flaps and continuously variable wingspans. The telescopic wing mechanism comprises an inner-section main wing, an outer-section main wing, a middle-section main wing embedded between the inner-section main wing and the outer-section main wing; inner, middle and outer flaps which are respectively connected with the inner-section mainwing, the middle-section main wing and outer-section main wing, a first linear motor and a second linear motor which are respectively used for driving the inner-section main wing, the middle-section main wing and the outer-section main wing to move in the spanwise direction, and steering engines respectively controlling the inner-section main wing, the middle-section main wing and the outer-section main wing. The ends of the front beam and the rear beam of the inner-section main wing are connected with a body, the front and rear beams of the wings are arranged in parallel in the unfolding direction, and the three sections of wing main wings stretch out and draw back in the front-rear beam direction and drive the three sections of flaps to stretch out and draw back. Telescopic positioning is achieved through a locking mechanism in the linear motor. Three steering engines are used for controlling folding and unfolding of the wings. The aerodynamic load of the wing is transmitted from theskin to the beam through wing ribs.

Description

technical field [0001] The invention belongs to the field of aircraft design and technology, and in particular relates to a telescopic wing structure with slotted flaps and continuously variable wingspan applied to a fixed-wing aircraft. Background technique [0002] Traditional aircraft mostly use a single wing aerodynamic layout to meet the aerodynamic requirements of their main mission conditions. However, some aircraft need to meet multi-mission conditions (such as taking into account high-speed cruise control and low-speed task cruise). At this moment, the wing of single aerodynamic layout can no longer adapt to the requirements of this type of aircraft design. This requires a wing design that can change its aerodynamic shape according to the requirements of the flight mission and take into account different speed requirements. For low Mach number (speed less than 300 km / h) flight conditions, changing the span of the wing and changing the camber of the airfoil by lowe...
