Abstract

The invention relates to an expandable single-duct aircraft, and belongs to the field of aircraft design. The expandable single-duct aircraft comprises an annular duct, propellers and an equipment cabin, the annular duct comprises a main duct wall, an expandable duct wall A and an expandable duct wall B, and the main duct wall, the expandable duct wall A and the expandable duct wall B are connected through rotary actuators and hinges; the propellers and the equipment cabinare both installed on a center shaft of the duct, the propellers provides advancing tension, and cross-shaped empennages are fixed between the equipment cabin and the main duct wall and between the expandable duct wall A and the expandable duct wall B; and in the fixed wing mode, the expandable duct wall A and the expandable duct wall B are expanded and are respectively and mechanically limited and locked with the main duct wall, and in the duct mode, the cross-shaped empennages are mechanically locked with the expandable duct wall A and the expandable duct wall B. The expandable single-duct aircraft has the following advantages: 1, the expandable single-duct aircraft has two modes of ducted flight and fixed wingflight; 2, a plurality of separable consumable unmanned aerial vehicles can be carried on the outer wall of the duct; and 3, the problems of a single ducted aircraft are solved.

Description

technical field [0001] The invention relates to an expandable single-duct aircraft, which belongs to the field of aircraft design. Background technique [0002] Single-duct aircraft has the characteristics of vertical take-off and landing, hovering and fast flight, and has been widely developed and researched in various countries. However, due to the small space inside the single-duct aircraft and the thrust of the engine to maintain the balance of gravity, this type of aircraft is only suitable for mounting small reconnaissance equipment; and the fuel consumption is high, the voyage time is short, and it cannot cruise for a long time; the flight resistance is large. low speed. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and to provide a deployable single-duct aircraft that takes into account both the fixed-wing mode and the duct mode. [0004] In order to achieve the above object, the presen...
