Embodiment 1

[0031] Embodiment 1, a design scheme of the fuselage structure of an integrated unmanned aerial vehicle (UAV) with three releases:

[0032] Select the fuselage structure of the upper monoplane layout, the back cabin 2 of the main force transmission structure connects the wing 4 and the empennage 14, and the belly cabin 9 is connected below the back cabin 2, and the middle fuselage cabin 10 is not needed. The structural design scheme of the dorsal compartment 2 can ensure that the belly compartment 9 is partly or not force-transmitted, so that the structural space of the belly compartment 9 is suitable for diverse loading flexibility. Due to the upper monoplane layout, two engines 3 are installed under the wing 4, and one is installed on the rear fuselage. For the convenience of supplying and delivering fuel for the engine 3, the fuel tanks can all be connected and installed in the cabin 2 of the machine. Fuel can also be loaded inside the wing 4 . The airborne system is conn...

Embodiment 2

[0039] Embodiment 2, a structural design scheme for the cargo compartment of a cargo drone with three layouts:

[0040] Option 1: Multiple releases on a single wing

[0041] Choose the fuselage structure of the upper monoplane layout, arrange the main force transmission structure on the back cabin 2, the main structure of the wing 4 and the empennage 14 are connected with the back cabin 2, and some equipment of the fuel tank and the airborne system can be arranged In the dorsal compartment 2. The back cabin 2 is connected with the belly cabin 9 through the middle fuselage cabin 10, and the load-bearing structures of the three are connected correspondingly. In the case where the middle fuselage compartment 10 is used as a cargo compartment, the space volume of the belly compartment 9 can be reduced, and the force transmission structure is mainly arranged in the connection structure with the back compartment 2 and the main landing gear 11.

[0042] Choose three layouts, instal...

Abstract

The invention discloses a design method and system for an aircraft with a multi-engine layout modular structure, the multi-engine layout comprises 2-3 engines, and an aircraft body structure of the modular structure comprises three component structures including an aircraft back cabin, a middle aircraft body cabin and an aircraft belly cabin of an aircraft body and various cabin door structures on the aircraft body; wherein the connecting and mounting positions of wings on the aircraft body can be adaptively adjusted. The layout of three engines is optimized, and the modular structure design is combined, so that continuous and safe flight of three engines or double engines is realized, the engines are convenient to use and maintain, and the attendance rate is increased. And a weight center-of-gravity monitoring scheme of the aircraft is designed for a user. And the module structure design is convenient for shortening the refitting development period, reducing the cost and improving the value.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to an aircraft with a multi-release layout module structure. Background technique [0002] Most of the current transport class and general class aircraft adopt single-engine or double-engine layout. Aircraft with double engines can provide a certain guarantee for safe landing in single-engine working state. Passengers' confidence in flight safety affects the development of general aviation. The dual-release layout for general aircraft is usually used on larger aspect ratio aircraft. In use, after the single engine of the double release station stops, it can be restarted in the air and choose the nearest landing. Continuous flight under special circumstances still has great safety risks. First, bad weather conditions, second, flawed driving skills, and third, restrictions on maneuvering aircraft or maneuvering flight. Installing the multi-engine layout of three e...
