Embodiment 1

[0022] as attached figure 1 Shown: An aerodynamic layout structure of a combined aircraft oriented to collaborative tasks, including a main engine 1 and two slave aircraft 2, the main engine 1 adopts the layout of a diamond-shaped wing at the front and a forward-swept wing at the rear, and the main engine 1 adopts a canard wing with a large aspect ratio Tailless layout, two sub-machines 2 are symmetrically distributed on both sides of the main machine 1, each sub-machine 2 adopts a flying wing layout, and each sub-machine 2 is embedded between the diamond-shaped wing and the forward-swept wing of the main machine 1, and adopts an embedded The design can block each other between the main unit 1 and the sub unit 2 in multiple directions. According to the analysis of electromagnetic characteristics, the radar reflection area is much smaller than other existing combined layout designs of the same size. The length of each slave 2 is 30% of the length of the host 1 . Both the slave...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that in this embodiment, both the main engine 1 and the two slave aircraft 2 use a vertical tail or a V-shaped tail design, so that the lateral stability can be enhanced.

Abstract

The invention discloses a combined aircraft aerodynamic layout structure for cooperative tasks, and particularly relates to the field of overall design of aircrafts. The combined aircraft aerodynamic layout structure for the cooperative tasks comprises a main machine and two sub-machines, the main machine adopts the layout of a front rhombic wing and a rear sweep-forward wing, the two sub-machines are symmetrically distributed on the two sides of the main machine, each sub-machine is embedded between the rhombic wing and the sweep-forward wing of the main machine, and the main machine and the two sub-machines have a complete flying wing layout in a combined state. By the adoption of the technical scheme, the problem that gravity center change and pneumatic center change are caused by neutron machine separation of an existing combined aircraft is solved, and different flight task requirements can be met.

Description

technical field [0001] The invention relates to the field of aircraft overall design, in particular to an aerodynamic layout structure of a combined aircraft oriented to cooperative tasks. Background technique [0002] Combination aircraft is a new aircraft design concept and a new layout method that breaks through the bottleneck of conventional aircraft layout performance. In the case of aircraft combination layout, the combination of aircraft with different functions has achieved the performance improvement of 1+1>2 and 1+2>3 in different mission stages. The existing combination layout of aircraft is mainly in the form of a main machine carrying multiple small sub-machines, and according to different mission requirements and different mission stages, tasks are performed in a combined form or in a separate form. [0003] There are several problems in the existing combined layout method: the separation of the sub-machines brings about a large change in the center of g...
