Penetrating High Wing Structure of Civil Aircraft with Blended-Wing-Body

Abstract

The disclosure provides a penetrating high wing structure of civil aircraft with blended-wing-body, wherein the structure comprises a left wing, a right wing and a high wing penetrating central wing. The left wing and the right wing are symmetrically arranged and connected to two sides of the high wing penetrating central wing through fasteners respectively, and the high wing penetrating central wing is arranged on the top of the main body. The left wing and the right wing both comprise wing ribs and wing spars that are arranged in a crisscross way. The disclosure proposes a penetrating high wing structure, wherein the wing and the body are designed as a whole so that the wings will not damage the continuity of the internal space of the body, which improves the load transfer efficiency of the structure and reduces the fasteners used for connection, thus reducing the weight of the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The disclosure will now be described in detail with reference to the drawings and embodiments to more clearly clarify the purpose, technical solution and advantages of the disclosure. It should be understood that the preferred embodiments described herein are only to explain the disclosure and are not intended to limit the disclosure.

Embodiment

[0027] A penetrating high wing structure of civil aircraft with blended-wing-body, as shown in FIG. 1-2, wherein the structure comprises a left wing 11, a right wing 4 and a high wing penetrating central wing 13;

[0028] the left wing 11 and the right wing 4 are symmetrically arranged and connected to two sides of the high wing penetrating central wing 13 through fasteners 12 respectively, and the high wing penetrating central wing 13 is arranged on the top of the main body;

[0029] the left wing 11 and the right wing 4 both comprise wing ribs 10 and wing spars 9 that are arranged in a crisscross way; the wing ribs 10 and wing spars 9 near the outer side of the left wing 11 are sparsely arranged, and the wing ribs 10 and wing spars 9 near the inner side of the left wing 11 are densely arranged.

[0030] The high wing penetrating central wing 13 comprises a plurality of longitudinally arranged central wing frames 3 and a plurality of central wing spars 2 fixedly mounted in the central wing frames 3.

[0031] The left wing 11, the right wing 4 and the high wing penetrating central wing 13 are designed as a whole so that the wings will not damage the continuity of the internal space of the body, which shortens the force transmission path, improves the load transfer efficiency of the structure, and reduces the fasteners used for connection, thus reducing the weight of the body; moreover, the connection mode of the left wing-central wing-right wing is adopted, which simplifies the connection mode of the wings on both sides and improves the carrying efficiency compared with the connection mode of the left wing-body-central wing box-body-right wing;

[0032] the main body comprises a pressurized cabin 17 and a cargo hold 16; the pressurized cabin 17 is fixedly mounted at the bottom of the high wing penetrating central wing 13, and the cargo hold 16 is fixedly mounted at the bottom of the pressurized cabin 17; two sides of the pressurized cabin 17 are provided with a plurality of cabin doors 18 and emergency cabin doors; a plurality of partitions 15 are arranged in the pressurized cabin 17.

[0033] Specifically, the front end of the main body is connected to a nose 1 through a first transition section 14; the rear end of the main body is connected to a rear body 8 through a second transition section 5; an engine 7 is provided in the upper center of the rear body 8, which can reduce the noise in the cabin and improve the comfort of the civil airliner after the noise is shielded by the wings; the tail fins 6 are provided on both sides of the rear body 8.

[0034] The penetrating high wing structure provided by the disclosure is an integral structure with a high space utilization rate, which facilitates the arrangement and installation of the distributed propulsion system, the realization of distributed electric propulsion of the aircraft, and the arrangement of the integral fuel tank and battery pack; facilitates the shape and structure design of the transition section between the wings and the body to realize the efficient and smooth transition between the wings and the body and good aerodynamic characteristics, thus achieving the purposes of reducing fuel consumption and developing green aviation; facilitates the balance of bending moment, axial force, shear force and torque transmitted by the wings on both sides, and the load balance with the body structure; facilitates carrying and transmitting the pressurized load generated by the body and the bidirectional bending moment, torque and axial force of the body.

[0035] Moreover, the height of the wings above the ground is high, which shortens the height of the cabin/cargo hold above the ground and facilitates quick boarding and deplaning/loading and unloading, so the structure is suitable for large and medium-sized aircraft with blended-wing-body.

[0036] Although the disclosure has been illustrated and described herein with reference to preferred embodiments, it should not be construed as limiting the scope of the disclosure. Any modifications, equivalent substitutions and improvements that are within the spirit and principle of the disclosure are intended to be covered by the protection scope of the disclosure.
