Description
Technical field
This utility model relates to a kind of new forms of energy aircraft external fuel cell structure, is specifically related to a kind of new forms of energy aircraft external fuel cell.
Background technology
Oil is as national strategy reserved resources, in national defence, the people's livelihood is occupied critical role, but petroleum resources is the most exhausted increasing with exploitation difficulty, the each side such as national security will be adversely affected, simultaneously, the demand of China's Civil Aviation Industry also increases every year rapidly, more and more higher to cleaning green energy resource also cry, and novel energy such as natural gas, hydrogen etc. are the most progressively applied, it is easily exploited, after burning, noxious emission is few, the hugest in the proved reserves of China, it is that following China will the novel energy of important development application, in order to reach efficiently to utilize the purpose of this kind of novel energy such as gas fuel, it is generally required to its temperature is maintained about-100 ~-300 degrees Celsius, form liquefaction to facilitate storage, transport, use.Compared to original aviation fuel, the appearance of this kind of novel energy is irresistible, and liquefaction density is less, designs to the military aircraft to weight extreme sensitivity and bring enormous benefits.Army specifications can be towards the aircraft external fuel cell structure of New-type fuel storing and using particular job environmental demand of civilian seaworthiness is met accordingly, it would be desirable to a kind of.
External fuel cell is common in modern military aircraft such as fighter plane, military transportation airplane class, and it primarily serves increase voyage, Large Copacity and effect and the feature such as is easily changed, and it is that inertial load is big, needs to seal internal pressurising and the high parts of rigidity requirement.External fuel cell typically uses the metal materials such as steel become to seal container to be welded as dominant shape and be connected with hanger by complicated machinery connection, and its eyelid covering is big due to absolute area, is total main by weight source in addition to fuel oil.Meanwhile, in order to reach the requirements such as sealing, the general steel alloy using corrosion-resistant weldable to connect is as eyelid covering and carriage, beam composition external fuel cell, and eyelid covering is also serving as aerodynamic configuration face to reduce resistance as its tubbiness cross section while sealing container.
At present, this military external fuel cell structure can only cannot meet the specific demand of New-type fuel towards normal aircraft fuel, also the needs of civil aircraft seaworthiness can not be met, it is for preventing eyelid covering unstability simultaneously, also need to improve support stiffness with bigger skin thickness or increase rib, thus cause weight to increase.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, and number of parts is few, and rigidity is high, and lightweight, low cost, aerodynamic drag are little, towards seaworthiness, it is possible to bear the new forms of energy aircraft external fuel cell structure of novel energy low-temperature working environmental demand.
For solving above-mentioned technical problem, this utility model provides a kind of new forms of energy aircraft external fuel cell.
A kind of new forms of energy aircraft external fuel cell, it is characterized in that including: external fuel cell, inside panel, absolutely temperature layer, exterior skin, carriage, longitudinal beam and transition adapter coupling, the outside of described external fuel cell is provided with inside panel, being provided with one layer of exhausted temperature layer on described inside panel, described exterior skin is arranged on the outside of inside panel by carriage.
The outer surface of described external fuel cell is additionally provided with carriage, longitudinal beam and adapter coupling.
Described inside panel glueds joint with temperature layer absolutely.
Described exterior skin includes that before and after's two parts, the front portion of described exterior skin are mechanically coupled with carriage, and the rear portion of described exterior skin uses the composite material integral formed of normal temperature cure.
Described normal temperature cure material is HexPly M56/AS7.
The beneficial effects of the utility model:
This utility model defines the army specifications that meets of complete set and requires and towards the external fuel cell thinking of the new forms of energy aircraft having particular job environmental requirement of civilian seaworthiness and flow process, secondly this utility model goes out to meet army specifications and the external fuel cell structure towards civilian seaworthiness and design objective according to this thinking and flow scheme design, it achieves by the method for the simple low temperature resistant easy welding alloy inside panel splicing exhausted adiabator of cladding and is provided the support stiffness enough to inside panel by the exhausted adiabator being coated with while meeting the working environment demand of new type low temperature fuel, solve the stability problem of inside panel, significantly reduce construction weight.It is divided into the composite exterior skin of three sections bird is hit, to be struck by lightning, while the protection such as electromotor non-packet capacitive rotor destruction providing, by to its profile different-diameter and length ratio preferred under cruising condition angle-of-attack range, it is designed to water droplet streamlined, greatly reduce aerodynamic drag, weight is greatly reduced relative to metal skin simultaneously.Being arranged by the carriage optimized, beam and form simple efficient Path of Force Transfer, the selection of its hat section not only reduces the connection difficulty of the parts such as carriage, beam, eyelid covering, and is prone to check and change.Before machining, latter two main transition adapter coupling is by stretching out U-shaped rib, its web with beam, while carriage hat section median ventral plate is mechanically connected, the edge strip of U-shaped rib is simultaneously and beam, edge strip laminating in carriage hat section, play the deformation of control structure stand under load, reduce the effect of connected nail posting, simultaneously, before, latter two main transition adapter coupling each stretches out three auricles simultaneously and is connected with hanger, form couple in different directions to transmit by external fuel cell pneumatic, formed under inertial load is curved, cut, turn round load, it is readily disassembled simultaneously, conveniently whole external fuel cell is carried out quick replacement.The external fuel cell structure that the sandwich structure mainly formed by light alloy material, the warmest layer, composite and a small amount of carriage, beam form, its outer form drag is little, general construction is lightweight, compared to general external fuel cell loss of weight more than 30%, resistance reduces by more than 10%, while meeting novel energy particular job condition, require to be designed and towards civilian seaworthiness according further to army specifications so that it is fighter plane, transporter, unmanned plane, business airplane, civil aircraft can be applied to.
