Embodiment

[0047] For the convenience of follow-up research, the basic design parameters of the wing are listed below for the reference of designers. The outer section is 3 meters long, the middle section is 3 meters long, and the inner section is 2 meters long; wing load W / s=150kg / m 2 ; Wing area S=34.27m 2 ; Overload factor g = 1.5; Safety factor f = 1.5; The action point of the aerodynamic resultant force is at the chord point of 35%. Using the mechanical method to analyze the shear force of the lugs, the inner diameter of the lugs along the upper edge of the back beam is designed to be 12 mm, and the inner diameter of the lugs along the lower edge of the back beam is designed to be 9 mm. Similarly, the inner diameter of the lugs along the upper front beam is designed to be 15 mm, and the inner diameter of the lugs along the lower front beam is designed to be 10 mm.

[0048] Considering that the components of the four-bar hinge mechanism are simple and reliable, the present inventio...

Abstract

The invention discloses a novel folding wing. The novel folding wing is overall divided into an inner segment, a middle segment and an outer segment. Folding positions comprise a 90-degree position and a 180-degree position. A folding manner is simple, easy to implement and high in efficiency. A hinge four-rod mechanism is selected as a body of a driving mechanism, and meanwhile a hydraulic actuator cylinder is selected as a power source. On the aspect of materials, high-strength alloy hardened and tempered steel is selected as materials of shaft pins, and strength titanium alloy materials are selected as materials of connecting rod structures and lug sheets. Rotating and locking structures are arranged on upper flanges and lower flanges of an upper beam and a rear beam, and it is guaranteed that unlocking and locking are reliably achieved. In the design process of the novel folding wing, the size is determined by meeting certain strength requirements.

Description

technical field [0001] The invention belongs to the field of structural design of folding wings, and in particular relates to a novel folding wing and a driving and locking mechanism. Background technique [0002] With the advent of my country's first-generation carrier-based aircraft J-15, carrier-based aircraft as a special model began to be well known to everyone. The biggest difference between carrier-based aircraft and general land-based aircraft is the particularity of its combat platform. The aircraft carrier is known as a mobile airport, but due to the limitation of the shape and size, the volume of the aircraft carrier hangar is certain. How to carry more aircrafts in a limited space? The aircraft is one of the most concerned issues for aircraft carrier designers. [0003] Aircraft designers have been so thoughtful about saving space that they have designed planes that fold their wings. That is to say, the carrier-based aircraft can retract the outer wings after l...
