Three, goal of the invention

Various aircraft (dirigible, lifting airship, fire balloon, aircraft, helicopter etc.) advantage is separately extracted to combine and form aircraft of new generation---Composite airship.Make it have flexible fast lifting and the horizontal flight characteristic of high speed of helicopter, manufactured materials, the structure with dirigible, there is the load carrying ability of aircraft and the characteristic of running at high speed, allow portioned product have more the long timeliness function of all-weather flight, make it to become cheap " omnipotent aircraft ".

Four, solution

(1) take lifting airship technology as basis: 1, applied compression system changes the buoyancy size that volume that air bag arranges air changes dirigible, the object that reaches this aircraft of lifting (is about to the process that dirigible becomes lifting airship, refer to lifting airship application open file, its patent No.: 01111096.1).

2, by promoting passenger plane, put down at a high speed the front end (or rear end or rear and front end) that is contained in the fairing profile air bag of lifting airship to the screw propeller of motion, putting down to flying speed of raising lifting airship, makes it have part propulsion system structure and the function of aircraft.

3, in the air bag of lifting airship, open up one " vacant lot ", for manned loading and dress control system, what save traditional dirigible hangs the things such as indigo plant, lifting rope; Reduce air to the resistance of this dirigible and weather to hang basket in the infringement of people, machine thing, make it have the partial interior filling structure of aircraft and helicopter.

4 or applied solar energy battery membranes (as crystal silicon solar cell) to be covered in the outer air bag of lifting airship outer, collect aerial solar power as this kind of lifting airship, i.e. the energy of composite aircraft work.

(2) increase the method for load carrying ability: 1, borrow fire balloon principle.1. apply transparent membrane and make the air bag of this dirigible, allow light gas in solar energy heat air external capsule, in capsule, use material or the device that absorbs luminous energy, as black paper, cloth etc.2. apply electro-heat equipment (as the thermal chemical reaction of heating wire or combustible or heat release heat absorption etc.), the light gas in heating or cooling air bag.

2, improve and put down to flying speed, monnolithic case, the lifting force of change dirigible.

3, the auxiliary lifting force that produces of application power system.

Five, advantage

1,, aloft under static state or dynamic condition, steadily vertical lift, is equivalent to helicopter.Increased safety factor, airfield runway run-up is not taken off and slides deceleration; And speed of response is fast, easy and simple to handle.

2, streamline contour ectosome, can constant-bearing navigation.The level with passenger plane at a high speed and be subject to air resistance little, speed can reach per hour tens kilometers to hundreds of kilometer, be equivalent to automobile, be applicable to civilian.

3, light gas recycles for a long time, saves the energy and fee of material, and this composite aircraft is simple in structure, with low cost, easy to operate, convenient and practical.The lifting force of Composite airship is provided by light gas, and in the situation that load carrying ability is identical, its volume is large compared with helicopter, while accelerating flight, is subject to air resistance larger, therefore it is put down to flying speed not as good as aircraft and helicopter, speed is moderate, is particularly suitable for civilian, family expenses.

4, combine the advantage of dirigible and fire balloon, use the material of part fire balloon and dirigible, produce material and be easy to get, and easily manufacture, cheap practical.Under equal conditions, this aircraft has dwindled air bag volume, has increased load carrying ability.

5, applied solar energy, as the Composite airship of the work energy, has reduced consumption, has increased the skyborne flight length of the halt of this dirigible, for all-weather flight provides energy safeguard.

6, the same aircraft of Composite airship, helicopter are compared: due to the lift (claim again lifting force, lifting force equals buoyancy loss of weight power) of this dirigible, the buoyancy producing in air by light gas provides, low to the power requirement of power system, conduct oneself with dignity minimum, and energy consumption is also few.The lifting force of aircraft provides by power system, and passenger plane is by flying speed and the runway help-fly of improving the standard, by the rotation generation lifting force of fairing external form (being fluid continuity principle and Bernoulli theorem) and screw propeller; Helicopter is by changing the high speed rotating of engine screw propeller, produce the lifting force differing in size, realizing lifting.So their power system: weight is large, power requirement is high; While producing passenger plane and helicopter, material requirements is harsh.

Six, accompanying drawing explanation

Fig. 1, be Composite airship dimension sketch, wherein: (1) is screw propeller, during for constant-bearing navigation left/right rotation, controlling party to and flying speed.(2) be the outer air bag of composite bed.(3) be tail fin: for supporting dirigible and auxiliary directional navigation.(4) be capsula interna.(5) be load-carrying chamber door, of bag material or woven dacron, make, of slide fastener or hasp folding.(6) for dirigible is stopped the strong point.

Fig. 2, be Composite airship cross-section structure simplified schematic diagram, wherein: (7) are outer air bag composite and air chamber thereof, requiring between double-walled can relative motion, and the object of using composite to add air chamber is to reduce the aerial friction drag of dirigible and pressure drag; If the quantity of interval air chamber between increase bilayer, will reduce the horizontal resistance of air.(8) be fixing lightweight air chamber, the interior light gas (identical with the light gas of external capsule gas and composite air chamber) of this air chamber is not participated in compression cycle; The object of using this air chamber is the rigidity that increases dirigible front end, the resistance of air to dirigible during antagonism flight.(9) for the inner chamber skeleton (again claim fin) of manned loading with dress compression system, dress control part, of the material that wing gliding parachute skeleton is identical, make; Prevent that capsula interna from subsideing to load-carrying chamber.(10) be the strut bar of support helix oar, if when screw propeller is directly fixed on air bag front end, can save this bar.(11) be load-carrying chamber ship type sole, require to fix with skeleton, increase after base areas, just dwindle people and the thing base pressure to air bag; It makes (as plank, plastic flagstone etc.) with light weight board, is fixed on air bag inwall or air bag the latter half is directly made with light weight board with restricting, and the first half is made with air bag material.(12) be the pressure schematic lines of air to motion synthesis dirigible.

The selection of bag material: lightweight, any surface finish, stiffness high (reason is to reduce windage resistance, Reducing distortion and improve inflation performance, the polyester dacron of the anti tear of coated on both sides ultra-violet radiation resisting is made).Air bag monnolithic case is streamline contour (reason is the resistance of air while reducing airship flight, increases air to the lifting force of dirigible and constant-bearing navigation ability, and foundation is fluid continuity principle and Bernoulli theorem), requires sealing air tight.

The whole selection principle of Composite airship: weight is lighter, intensity is more high better.
