Abstract
The invention discloses a measurement and control cable for an aircraft engine. The measurement and control cable comprises multistrand pure nickel conductors which are packaged in a same pure nickel wire woven main shielding layer. The pure nickel wire woven main shielding layer is wrapped with a FEP sheath. Outside the pure nickel conductors are coated with synthetic mica, a silicon oxide fiber braiding layer, a high-temperature resistant coating, and a pure nickel wire woven branch shielding layer in turn. The measurement and control cable solves a problem that a cable in the prior art can not realize high performance, light weight, high reliability, high-temperature resistance, etc. at the same time. Through selecting materials and designing cable structure, interactive contradictions among cable high-temperature resistant requirement, cable external diameter setting, working voltage requirement, and transmission requirement are solved and the high reliable measurement and control cable used for aircraft engine measurement and control is provided.

Aforesaid aircraft engine observing and controlling cable is characterized in that: it is 0.08mm～0.12mm that said pure nickel wire braiding sub-shield, pure nickel wire weave the stranded diameter of sewing the pure nickel wire that line adopts of total screen and pure nickel monofilament.
Aforesaid aircraft engine observing and controlling cable is characterized in that: the count that said pure nickel wire braiding sub-shield and pure nickel wire weave total screen is all greater than 80%.
The invention has the beneficial effects as follows: through adopting ultra-thin synthetic mica, fine pure nickel monofilament, high temperature oxidation resisting silica fibre silk and high-temperature resistant coating; Anti-loose, fine stranded ad hoc structure and the technologies such as line, FEP sheath sewed of permanent tension force make cable of the present invention have following advantage:
1, long-term nominal operation temperature range is :-60～500 ℃;
2, short-term Nai Tegaowen flame characteristics: anti-1100 ± 100 ℃ of flames winding-up 30 minutes;
3, satisfy the various different specific (special) requirements of high-temperature region and low-temperature space simultaneously, greatly improved the reliability of institute's connection line cable;
4, good electric durability can;
5, good core-screen capacitance characteristic;
6, the earth resistance of cable shielding is adjustable;
7, need not to carry out special protection against the tide, anti-wet process during long term storage.

Among the figure: 1, pure nickel conductor, 2, synthetic mica, 3, the silicon oxide fibre braid, 4, high-temperaure coating, 5, pure nickel wire braiding sub-shield, 6, pure nickel wire weaves total screen, 7, the FEP sheath, 8, the stranded line of sewing of pure nickel monofilament.
Embodiment
To combine Figure of description below, the present invention will be further described.
A kind of aircraft engine observing and controlling cable; Comprise multiply pure nickel conductor 1; Said multiply pure nickel conductor 1 all is wrapped in same pure nickel wire and weaves in total screen 6, and said pure nickel wire weaves total screen 6 outer FEP sheaths 7 that also are enclosed with, said each pure nickel conductor 1 outer synthetic mica 2 and silicon oxide fibre braid 3 of all being enclosed with successively; Said silicon oxide fibre braid 3 is wrapped with high-temperaure coating 4, the said high-temperaure coating 4 outer pure nickel wire braiding sub-shields 5 that also include.
Said pure nickel conductor 1 adopts and parts the stranded technology of power a little, makes it to become the multiple twisted wire core of multiply pure nickel, guarantees that stranded conductor has corresponding pliability and rounding property; Said synthetic mica 2 is the wrapped ultra-thin synthetic mica of permanent tension force, and thickness is 0.08mm～0.10mm, and synthetic mica 2 is wrapped in outside the pure nickel conductor 1, and said silicon oxide fibre braid 3 employing Tex are 30～60 high temperature oxidation resisting silica fibre silk, and the low-tension braiding forms; Ultra-thin synthetic mica 2, silicon oxide fibre braid 3 and high-temperaure coating 4 have been guaranteed the Stability Analysis of Structures of this cable; Satisfied the requirement separately of setting, electric strength and the transmission electric capacity of external diameter simultaneously; Solved that mutual restriction is difficult for balanced contradiction between the three; Make cable have the characteristic (1100 ± 100 ℃ of flames winding-up 30 minutes, cable still can operate as normal) of short-term Nai Tegaowen flame; Pure nickel wire weaves total screen 6 simultaneously, and the employing diameter is that the pure nickel wire high-tension braiding of 0.08mm～0.12mm forms, and count is greater than 80%.Guaranteed that the cable general structure stablizes rounding, and the earth resistance that shields during the high low temperature of cable meets the requirement of setting, greatly alleviated the weight of whole cable simultaneously; The application of FEP sheath 7; Realized that the high-temperature region cable is connected (when reality is used with the connectorless of low-temperature space cable; The FEP sheath of high-temperature region cable part is removed); Both make former high low-temperature space device work into unit cable by the connection of two cables through coupling and directly connect high low-temperature space device work; Fail safe and the reliability that has improved this observing and controlling cable connection line low-temperature space cable in addition also has good protection against the tide, moisture-proof characteristic, also alleviated the weight of whole CA cable assembly simultaneously.Thereby need not the protection against the tide of special protection, a damp proof difficult problem when also having solved this high reliability cable long term storage.
The said high-temperaure coating 4 outer pure nickel wire braiding sub-shields 5 that also include; The pure nickel wire high-tension braiding that said pure nickel wire braiding sub-shield 5 employing diameters are 0.08mm～0.12mm forms; Count is greater than 80%; Cable structure is stable when having guaranteed the high low temperature of cable, and each item characteristic all meets the requirement of setting, also plays the effect that alleviates cable weight simultaneously.
Said pure nickel wire weaves the gap location that forms between gap location that total screen 6 and each pure nickel wire braiding sub-shield 5 forms and each pure nickel wire braiding sub-shield 5 and is equipped with the stranded line 8 of sewing of pure nickel monofilament; The stranded line 8 of sewing of said pure nickel monofilament is the stranded stranding of pure nickel wire low stress of 0.08mm～0.12mm; Guarantee the stable rounding of the construction of cable, also realized cable ground connection adjustability and accordance.
In sum; A kind of aircraft engine observing and controlling cable provided by the invention; Through material selection, cable structure and suitable technological design solve that the high temperature resistant requirement of cable, cable external diameter are set, operating voltage requires and the requirement of transmission property between the contradiction of mutual restriction, provide a kind of aircraft engine observing and controlling with high reliability observing and controlling cable.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range by appending claims and equivalent circle thereof.
