Description

A kind of light-duty unmanned dirigible

Affiliated field

The utility model relates to a kind of dirigible, particularly a kind of light-duty unmanned dirigible.

Background technology

Though old-fashioned dirigible was invented 50 years than aircraft is early, and is also once much-vaunted in air transport and Two World Wars, withdrawed from the arena of history because of backward in technique in nineteen thirty-seven.Since 1970, modern dirigible begins to be subjected to the great attention of World Airways circle, is bringing into play important effect in a lot of applications at present.

Dirigible is because of the difference of flight control (or control) mode, can be divided into three types in remote control airship, driverless operation dirigible and manned dirigible.In the last thirty years, produced the remote control airship and the manned dirigible of multiple model both at home and abroad, but light-duty unmanned dirigible yet there are no precedent.The airworthiness of remote control airship is lower both at home and abroad at present, it is main because remote control distance is very near, have only about one kilometer,, generally in several kilometer range, fly so the flight voyage is very short, flying height is low, generally in flight below 500 meters, useful weight is little, is generally about 10 kilograms, field of application is little, generally the carrier that flies as small-sized advertisement.Though manned dirigible airworthiness is better, because of bulky, be generally 6000～10000 cubic meters, so flight resistance is very big, requiring has high-performance driving engine, and promptly energy consumption is bigger, and flight inertia is very big, and manoevreability and road-holding property are relatively poor.More not enough is, manned dirigible needs bigger place when taking-off and landing, navigation, communication and flight control equipment or the like flight facilities also need be set guarantee flight safety, so the manufacturing cost of manned dirigible and operation flight price are all very high, current also being difficult to plays a greater role aspect civilian.

Goal of the invention

The purpose of this utility model promptly is to overcome the shortcoming of prior art, provide a kind of and need not carry out manned light-duty unmanned dirigible, it carries autopilot by ship and flight control unit carries out Autonomous Control and flight according to mission program that sets in advance and predetermined vector, flying distance is far away, flying height is higher, cruise duration and capacity weight are all bigger, applied range.

The purpose of this utility model is achieved through the following technical solutions: a kind of light-duty unmanned dirigible, and it comprises hull, engine installation, thrust deflexion device, beeper, flight control unit, data link and surface control station;

Hull is made up of air bag, nose cone, empennage and gondola, hull is a fairing, and air bag is divided into external capsule and capsula interna, and the air bag afterbody is provided with " X " T tail, belly is provided with the streamline contour gondola, head is provided with the detouchable nose cone, and the main body of hull is an air bag, and empennage contains the control rudder face, gondola is positioned at the air bag bottom, gondola contains alighting gear, and driving engine and letter road, mounted engine and screw propeller in the letter road are installed in the rotating shaft of gondola both sides; Thrust deflexion device, beeper and flight control unit all are positioned at gondola, and the fuel tank in the gondola is by the driving engine in the pipeline butt joint letter road.

Engine installation is made up of piston aviation engine, electrical generator, feed apparatus, ignition device, ducted propeller and actuator, and ducted propeller is four leaf fixed pitch propellers;

The thrust deflexion device comprises that hybrid aviation stepping motor connects worm type of reduction gearing, links to each other with single chip machine controlling circuit and is controlled by single chip machine controlling circuit;

Beeper comprises receiver and steering wheel on ground transmitter, the ship, and distance increasing unit is installed on the ground transmitter;

Flight control unit by GPS receiver, navigation and mission payload control computer, flight stability control computer, fly to control sensor, remote control receiver (part controllable function, servo steering wheel interface;

Data link is made of radio transmitter on the ship and ground receiver;

Surface control station is the remote-control romote-sensing display terminal.

By top narration as can be seen, the utlity model has following advantage: very approaching with manned dirigible aspect main airworthiness such as flying height, flying distance, flying speed and cruise duration, and be higher than remote control airship far away, manufacturing cost is again far below manned dirigible (about 30%), thereby can satisfy the technical requirements of multiple application, the utility model can effectively solve at present a lot of existing a pair of conspicuous contradictions of dirigible, be advanced technology and low-cost problem, have very big practical value aspect military equipment modernization and the General Aviation.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described: a kind of light-duty unmanned dirigible, it comprises hull, engine installation, thrust deflexion device, wireless remote controller, flight control unit, data link and surface control station;

Shown in Fig. 1 a, b, c, hull is made up of air bag, nose cone 2, empennage 3 and gondola 4, and hull is a fairing, air bag is divided into external capsule 1 and capsula interna, and the air bag afterbody is provided with " X " T tail 3, and belly is provided with the streamline contour gondola, head is provided with detouchable nose cone 2, the main body of hull is an air bag, and empennage 3 contains the control rudder face, and gondola 4 is positioned at the air bag bottom, gondola 4 contains alighting gear, shown in Fig. 2 a, b, c, driving engine and letter road 5 are installed, mounted engine and screw propeller in the letter road 5 in the rotating shaft of gondola both sides; Thrust deflexion device, beeper all are positioned at gondola 4, and the fuel tank in the gondola 4 is by the driving engine in the pipeline butt joint letter road 5.Charge into low density gas to streamline contour main gasbag 1, for example can obtain the quiet buoyancy of balance flying weight behind helium or the hydrogen; Balloonet is used to regulate air bag internal pressure and pitching flight attitude after charging into air; Empennage 3 can play the effect that stabilized flight attitude and rudder face are controlled airship flight; Gondola 4 is used to load ships such as engine installation, measure and control device and capacity weight and carries equipment; Nose cone 2 can bear the front Pneumatic pressure and keep the hull profile.The air bag profile adopts the Natural Laminar Flow technology to design, and can improve 1ift-drag ratio 7～11%, and " X " T tail 3 can improve flight control and flight maneuver.The section shape of gondola 4 is pushed down triangular design, can improve flight stability, reduces flight resistance.
