Abstract

The invention discloses a V-shaped empennage device suitable for a sea and air across amphibious unmanned aerial vehicle. The V-shaped empennage device comprises a left balance wing, a right balance ring, a left control rudder, a right control rudder, a left rudder pedal, a right rudder pedal, a first empennage steering engine, a second empennage steering engine, a left empennage connecting rod, a right empennage connecting rod, a front empennage bracket, a rear empennage bracket, a front empennage connecting rack and a rear empennage connecting rack, wherein the front empennage bracket, the rear empennage bracket, the front empennage connecting rack and the rear empennage connecting rack are in parallel and opposite to one another and are arranged on the left empennage connecting rod and the right empennage connecting rod; the left rudder pedal is arranged on the left control rudder; the right rudder pedal is arranged on the right control rudder; the first empennage steering engine is arranged on the left balance wing; and the second empennage steering engine is arranged on the right balance wing. Each steering engine of the empennage control rudder is provided with a sealing shell, so that the steering engine also can normally work under underwater navigation; forward power is provided by an underwater propeller, and the rudder angle of the V-shaped empennage control rudder is regulated to realize flotation, submergence and turning motion of the unmanned aerial vehicle; and moreover, during air flight, the rudder angle of the control rudder is regulated to realize climbing, diving and turning motion of the unmanned aerial vehicle.

Description

technical field

[0001] The invention relates to a tail fin for an unmanned aerial vehicle, more particularly, a V-shaped tail fin device suitable for an amphibious unmanned aerial vehicle across 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 operated by radio remote...
