Problems solved by technology

[0006] Most of the current body systems are integrated shells, and their wings and tails are fixed structures. When the operating environment (such as underwater environment, air environment, etc.) changes, it cannot adjust its own body structure according to environmental changes, which hinders unmanned The application of computer in unstructured and changing environmental conditions

Abstract

The invention discloses an erection girder body suitable for a sea and air across amphibious unmanned aerial vehicle. The body comprises a first supporting rod, a second supporting rod, a third supporting rod, a fourth supporting rod, a first fixing plate, a second fixing plate, a third fixing plate, an erection girder shell, a supporting rod connecting disc and an erection girder outer sleeve, wherein the first supporting rod, the second supporting rod, the third supporting rod and the fourth supporting rod are supported through the first fixing plate and the second fixing plate which are arranged in parallel; the third fixing plate is arranged between the first fixing plate and the second fixing plate; the erection girder shell and the supporting rod connecting disc are connected through matching between the screw and the nut assembled in a lug; and one end of the erection girder outer sleeve is connected to the front end of the erection girder shell. The body has the rod piece structure, so that a sealing outer sleeve is not independently designed on the outer side, and when the unmanned aerial vehicle enters a water environment, gaps among various rod pieces can be rapidly filled with water, so that the average density of the unmanned aerial vehicle body is close to the density of water in a short time, and transition of the unmanned aerial vehicle from an air environment to a water environment is realized.

Description

technical field [0001] The invention relates to a fuselage of an unmanned aerial vehicle, more particularly, a fuselage with a girder structure suitable for an unmanned aerial vehicle with amphibious survivability in the sea and air. Background technique [0002] UAV is the abbreviation of unmanned aerial vehicle, and the English abbreviation is UAV (Unmanned Aerial Vehicle). [0003] The most important requirement for the design of the UAV is to be as light as possible while the fuselage system is strong enough. However, UAVs under various mission load requirements leave very limited space and quality quotas for motion transmission mechanisms. It is necessary to flexibly and efficiently convert basic engineering driving motions, such as high-speed rotation, into favorable controlled motions. The basic aviation transmission methods include direct drive, proportional amplification drive, electric servo drive and hydraulic servo drive. [0004] UAV is an unmanned aircraft op...
