Abstract
The utility model in outmost surface by after radome fairing mold upper berth discharges several layers of glass fibre prepreg cloths, laying one layer of metal mesh, protection enamelled coating is sprayed in metal mesh outer surface again.When aircraft is in thunderstorm weather flight, if spinner is struck by lightning by high pressure, this layer of metal mesh can form a forceful electric power circulation road with propeller hub and aircraft, and thunder-strike current is transferred to aircraft, forms equipotentiality body, ensures flight safety.The utility model radome fairing weight reduces, so that aircraft own wt reduces, is provided simultaneously with anti-lightning strike function.
Description
Technical field
The invention belongs to Design of Mechanical Structure, are related to a kind of spinner.
Background technology
The function of radome fairing is to reduce propeller incoming disorder, meanwhile, it is capable to play certain protective role to internal propeller hub.
The shortcomings that radome fairing installation site is shown in that Fig. 1, former radome fairing are made of metal material, metal fairings is that weight is big, corrosion resistance
It can be poor；Start to manufacture radome fairing using composite material now, but the design requirement of aircraft anti-lightning is spinner tool
There are the electric shock for bearing multipass 50kA, and the ability that can be shocked by electricity by a 200kA.And composite material is unlike metal material
There is good electric conductivity like that, so, composite material radome fairing must have special anti-lightning strike measure.
Invention content
The object of the invention：The present invention manufactures radome fairing using composite material, and the radome fairing has anti-lightning strike function.
Technical solution of the present invention：A kind of spinner, which is characterized in that including composite material radome fairing, radome fairing
It is by inner surface exterior surface：Composite plys 4, metal mesh 3, composite plys 4 cover one layer of metal mesh 3 above,
120 DEG C ± 5 DEG C, curing molding after 1.5h~2h is kept under the conditions of -0.09MPa.
Composite plys 4 are by one layer of 0 ° of glass cloth, one layer of 45 ° of glass cloth, one layer of 90 ° of glass cloth, one layer of 45 ° of glass
Cloth, one layer of 0 ° of glass cloth are constituted.
The metal mesh trade mark is CYB6T12-300FA, and thickness is 0.051mm ± 0.01mm, long pitch-row 2.54mm, short-bore
Away from 1.23mm.
The metal mesh outer surface spray protection enamelled coating.
Advantageous effect of the present invention：The present invention by after radome fairing mold upper berth discharges several layers of glass fibre prepreg cloths,
Outmost surface lays one layer of metal mesh 3, and protection enamelled coating is sprayed in metal mesh outer surface again.When aircraft is in thunderstorm weather flight, if
Spinner is struck by lightning by high pressure, this layer of metal mesh can form a forceful electric power circulation road with propeller hub and aircraft, will be struck by lightning
Electric current is transferred to aircraft, forms equipotentiality body, ensures flight safety.Radome fairing weight of the present invention reduces, so that aircraft itself
Weight reduces, and is provided simultaneously with anti-lightning strike function.

Specific implementation mode
The following further describes the present invention with reference to the drawings：
The present invention manufactures radome fairing using composite material, and the radome fairing has anti-lightning strike function.
The design requirement of aircraft anti-lightning, which is spinner, has the electric shock for bearing multipass 50kA, and can lead to
Cross the ability of 200kA electric shocks.And composite material has good electric conductivity unlike metal material, so, composite wood
Material radome fairing must have special anti-lightning strike measure.Ply angles figure is shown in Fig. 2 inside radome fairing, is by inner surface exterior surface：
Composite plys 4, metal mesh 3, composite plys 4 cover one layer of metal mesh 3 above, in 120 DEG C ± 5 DEG C, -0.09MPa
Under the conditions of keep 1.5h~2h after curing molding.Metal mesh structure is shown in Fig. 3, which is mounted on radome fairing outermost layer, when whole
When stream cover is by being struck by lightning, for transmitting thunder-strike current, radome fairing is prevented to be damaged.3 trade mark of metal mesh is CYB6T12-
300FA, thickness are 0.051mm ± 0.01mm, and long pitch-row 2.54mm, short-bore is away from 1.23mm.Metal mesh 3 is designed to reticular structure,
Therefore its metal conducting layer cross-sectional area is big, while ensure that small resistance value, reduces the weightening that lightning proof is brought.
It is an advantage of the invention that：Radome fairing weight reduces, so that aircraft own wt reduces, is provided simultaneously with anti-lightning strike
Function.
