Description

Inflatable rigid structure rigid airship

Technical field

The utility model relates to a kind of rigid airship of inflatable rigid structure, belongs to aerostatics branch in the aircraft field.

Background technology

Dirigible can be divided into soft, semihard formula and rigid three classes by its constructional feature.Rigid airship is made of rigid backbone outer cover plain cotton fabric or metal thin skin usually, thereby makes things convenient for the static lift and the aerodynamic force load of distribution dirigible, has increased load capacity greatly, simultaneously, and because of the inner and outside equipressure of its hull makes covering need not guarantee air-tightness.

In history, rigid airship is the carrying person of heavy load, and this class dirigible build is huge, and manoevreability is relatively poor relatively.The weight of rigid airship mainly comes from rigid backbone, and lightening material quality to greatest extent when guaranteeing mechanical strength is one of major subjects of rigid airship research.

Dirigible is the long hang time that it is potential than significant advantage of other aircraft, and present stage blimp all be faced with the Lou problem of helium, this makes this advantage effectively not bring into play.Therefore, how to solve Lou helium problem, also become the emphasis that various countries' dirigible is made area research.

Summary of the invention

The purpose of this utility model is to provide the rigid airship that a kind of material is light, load-carrying is big relatively, the hang time long, leakage helium rate is low, have excellent aerodynamic configuration.

Technical solution of the present utility model is: the dirigible system partly is made up of structure division (comprising buoyance lift gas air bag, load cabin, empennages etc. such as rigid backbone, plain cotton fabric, hydrogen helium), energy source and power propulsion system (comprising driving engine, screw propeller, fuel oil system and electric power system etc.), navigation control system and communication system etc.Wherein, rigid backbone is formed by hinged the connecing of High pressure air pole of some high strength airtight materials manufacturing, adopts standpipe and valve according to the control pressurer system that necessarily is linked in sequence between each gas column; Buoyance lift gas air bags such as inner several hydrogen helium of dirigible dependence hull produce static lift and come the deadweight of the balance hull overwhelming majority, the hull afterbody is installed by driving engine and screw propeller is formed power propulsion system, lifting, attitude and the heading of direction of passage rudder and elevating rudder control dirigible.

Hull is a back taper formula class spindle external form, has lower drag coefficient.Hull is supported by rigid backbone, meets the requirements to guarantee external form.Skeleton outer cover plain cotton fabric is in order to keep the streamlined contour of dirigible.Plain cotton fabric is selected light material, guarantee certain mechanical strength and uvioresistant aging resistance, does not need to guarantee air-tightness.

Rigid backbone is designed to this later-model notable feature.For guaranteeing enough mechanical strengths, traditional rigid airship skeleton is made by metallic material or advanced composite material, and light as far as possible principle is followed in selection.This novel selection casts off the framework idea of traditional dirigible once and for all, with high pressure gas pour into the tubulose sealing member that utmost point lightweight flexible envelop materials makes and the rigidity gas column that forms as the basic comprising unit of dirigible skeleton, greatly reduce the weight of rigid airship.Each rigidity gas column forms an integral body by modes such as hinged, bonding, hot melts, and the part gas column serves as the hull external form that the hull bus constitutes whole dirigible.By the pre-stage test checking, the inside and outside differential pressure that the rigidity gas column of at present common envelop materials manufacturing can bear surpasses 50KPa, and under this pressure reduction, the rigidity gas column can laterally bear hundreds of kilograms weight and not crooked, and we can be similar to and think that gas column is a rigid body.After using specific material and technology, the gas column inside and outside differential pressure has reached 0.1～1atm (1atm=1.01 * 10 ⁵Pa is a barometric pressure), its mechanical specialities will be near traditional rigid airship material.

The high pressure air post has its simple and unique pressure regulating system, so that the pressure in the gas column is maintained within a certain range, guarantees the rigid body characteristic of gas column.

Helium capsule stored helium is dirigible lift unit.Buoyance lift gas air bags such as inner one or more hydrogen helium of rectangular distribution of hull.Utricule is selected ultra-thin ultralow leakage material for use, need not guarantee tear strength.Buoyance lift gas air bags such as hydrogen helium adopt the zero-pressure pattern, and promptly gaseous tension and external atmosphere pressure are equal in this air bag.At present, the leakage rate of this type of envelop materials has reached 1mlD ^-1Atm ^-1M ^-2(be under the normal temperature, this material of 1 sq m 1 day, under the 1 barometric pressure pressure reduction, spillage is no more than 1ml).

Empennage is used to guarantee the stability and the road-holding property of dirigible, and it is fixed on the rear end in the hull outside, and empennage adopts " ten " type, " X " type or " Y " type layout of falling, and each rudder face can independent deflection ± 30 °.

Driving engine and screw propeller are installed in the hull afterbody, and the dirigible power that flies before providing is provided.

Navigation control system, communication system, energy resource system and control pressurer system etc. are installed in built-in utricule middle part, load cabin in the cabin.

Compare traditional dirigible, the utility model has following advantage:

(1) owing to adopted this new design philosophy of rigidity gas column, alleviates the dirigible deadweight greatly, increased load capacity.The proposition of the thought that this is new makes the rigid airship miniaturization become possibility, and this new structure is adopted on large-scale transportation dirigible top, and this advantage undoubtedly also can be fairly obvious.

(2) because buoyance lift gas air bags such as hydrogen helium have adopted the zero-pressure mode of operation, make leakage rate reduce by 2～3 orders of magnitude compared to traditional dirigible, this target that makes " the long-time sky that stagnates " this aerostatics circle competitively chase can perfectly realize;

(3) owing to adopted the hull bus of built-in design in load cabin and optimization, the drag coefficient of novel airship design plan is littler than the traditional design; Hard structure also makes dirigible need not consider problem on deformation when high-speed flight, thereby makes dirigible have higher manoevreability.
