Abstract

The invention discloses a cruise aircraft, the cruise aircraft is variable in type, can be a four-propeller aircraft capable of vertical take-off and landing, vertical hover and flexible flight, also can be deformed as a fixed wing cruise aircraft capable of long-distance raid, and can transform between the four-propeller aircraft and the fixed wing cruise aircraft according to the needs; during take-off and landing or in narrow space condition, wing tips folds downward, and can play the role of a landing gear or achieve the purpose of reducing the dimension of the cruise aircraft; while in cruise flight, 2 engines can turn 90 degrees, the other two engines shutdown, at the same time, the wing tips can be expanded, the cruise aircraft transforms as a delta wing layout fixed wing cruise aircraft with a high flight speed and a larger flight radius; when the cruise aircraft is in a fixed wing form flight, only 2 blade propellers are used for driving, energy is saved, and the flight radius is larger.

Description

A kind of cruise vehicle

Technical field

The present invention relates to a kind of cruise vehicle.

Background technology

Modern war is had higher requirement to cruise vehicle: should high maneuverability, possess again larger flying radius.Existing cruise vehicle scheme is difficult to meet above-mentioned requirements.Helicopter and four leaf oar aircraft all can vertical takeoff and landing, but Helicopter Flight Control System exploitation is complicated, easy care not, and four leaf oar aircraft energy consumptions are large, flying speed is low, flying radius is very little; Fixed wing aircraft flight energy consumption is little, flying radius is large, but vertical takeoff and landing realizes complexity with hovering, and is not suitable for the investigation in narrow and small location.

At present, vertical takeoff and landing cruise vehicle can be divided into two large classes: thrust orientation formula and deflected-thrust.Thrust orientation formula vertical takeoff and landing cruise vehicle comprises conventional depopulated helicopter and coaxial unmanned helicopter two classes; Deflected-thrust comprises 6 classes such as rolling leaf oar formula, the fuselage formula of verting and tilting duct formula, tail sitting posture and leaf oar, wing change type.There is mechanism's complexity in thrust orientation formula cruise vehicle, not easy care, flight control system complexity, the shortcoming such as energy consumption is larger in the time of long-distance raid; Deflected-thrust cruise vehicle or complex structure, is realized difficulty, or maneuverability performance deficiency.The present invention is directed to the deficiency of current vertical takeoff and landing cruise vehicle, combine the advantage of tilting duct formula vertical takeoff and landing cruise vehicle and fixed wing aircraft, a kind of more advanced deformable vertical takeoff and landing cruise vehicle is provided.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of taking 4 vertically arranged driving engines as power, and hovering, vertical takeoff and landing and the high maneuverability that can realize helicopter vertical direction utilize the lift of wing to carry out the cruise vehicle of the long-distance raid of relative low energy consumption with fixed wing aircraft.

The technical solution used in the present invention is: a kind of deformable vertical takeoff and landing cruise vehicle, comprising: middle leaf oar, fuselage, head leaf oar, alighting gear, front horizontal tail, tiliting axis, tail leaf oar, rear horizontal tail, folding wing tip; Described middle leaf oar has two, is fixed on tiliting axis, can do 90 ° of upsets with tiliting axis; Described folded wing is arranged on rear horizontal tail, can fold as required or launch, and can do auxiliary landing gear and use when folding; Described tiliting axis rotates and adopts Worm Wheel System, ensures the stability of motion; Described wing tip is folding and launch employing two condition four-bar mechanism, in rotation process, is slide block rocker mechanism; In the time that rocking bar moves to end position, utilize the friction between push rod end and dwang top, play the function of position and lock; Utilize gyroscope to assist and control the rotating speed of each motor, ensure that each motor coordinates better; Aircraft is right on the course turned to control guide-ring is mainly installed below duct, realizes turning by adjusting leaf grating angle.

The technique effect that the present invention will realize is: cruise vehicle type is variable, both having can be can vertical takeoff and landing, vertical hovering, four leaf oar aircraft of flight flexibly, can be deformed into again can long-distance raid fixed-wing cruise vehicle, can between these two, change as required; In the time of landing or in narrow space situation, wing tip is folding downwards, can play the effect of alighting gear or reach the object that reduces cruise vehicle size; And in the time of cruising flight, wherein 2 driving engines can overturn 90 °, another two engine cutoffs, meanwhile, wing tip can launch, and the fixed wing aircraft that cruise vehicle is deformed into delta wing configuration has higher flying speed and larger flying radius; While flight with fixed-wing form, only use 2 leaf oars to drive, save the energy, and there is larger flying radius.

Deformable vertical takeoff and landing cruise vehicle has the advantage of helicopter and fixed wing aircraft concurrently, has solved the problem of flight when cruise vehicle takes off and lands and grow boat under the conditions such as shortage runway, has higher practical significance.At military aspect, this cruise vehicle can be used for military surveillance, is not easy to situation of observation area etc. as the area of large area spaciousness carried out investigations, assisted soldier understand room, Jie Xiang corner etc.This cruise vehicle can be out of shape, thereby reduces own vol, for narrow space, region with a varied topography, as: the streets in forest, city etc., have very strong comformability.In addition, due to can vertical takeoff and landing, vertically hovering can long-distance raid, be particularly suitable for landing on warship, complete the tasks such as investigation to marine site, inland city.Meanwhile, also can play one's part to the full at the aspect such as anti-terrorism, security.Aspect civilian, due to this cruise vehicle can landing under complex environment, topographic condition, flight, both can observe on a large scale, can realize and staring for certain objects again, therefore, can obtain widely application, as disaster assistance and assessment, geological exploration, take photo by plane, device for electric power line patrol etc.Add and can carry out customized design and improvement for application-specific background, this cruise vehicle can, obtaining application in field more widely, have good market outlook.

Detailed description of the invention

The invention provides a kind of hovering, vertical takeoff and landing and the high maneuverability that both can realize vertical direction as helicopter, can as fixed-wing, utilize again the lift of wing to carry out the cruise vehicle of the long-distance raid of relative low energy consumption simultaneously.

Under different aerial missions, cruise vehicle can be out of shape, and switches, thereby meet the demand of varying environment between four leaf oar aircraft and Fixed Wing AirVehicle.Cruise vehicle vertical takeoff and landing or need to reduce cruise vehicle size time, its wing tip is folding, is four leaf oar aircraft; In the time of cruising flight, wing tip launches, be Fixed Wing AirVehicle when 90 ° of duct upsets.

When vertical takeoff and landing, wing tip is folding, and 4 leaf oars, as power, form four leaf oar aircraft, can easily realize vertical takeoff and landing function, and folding wing can be used as alighting gear use simultaneously; In the time of cruising flight, two leaf oars overturn 90 °, promote cruise vehicle flight, and other two leaf oars cut out, and can save energy consumption; Meanwhile, wing tip launches, and forms delta wing aerodynamic arrangement, is convenient to cruising flight, has higher flying speed and larger flying radius.In addition, if necessary, as flight space hour, wing tip is folding, can effectively reduce cruise vehicle size.
