Abstract
The utility model relates to a kind of fuselage side RECTIFYING ANTENNA cover, wing antenna cover is long 1.89m, width 1.65m, thickness 0.44m, and by taking certain type machine as an example, antenna house is arranged in aft body.To reduce the prominent fuselage appearance thickness of antenna house, embedded combination pressure-tight box is designed as antenna mounting platform, guarantees that two interferometric antenna arrays half are embedded in fuselage installation, greatly reduces the thickness of antenna house.Further, it is contemplated that antenna house maintainability and the light requirement of disassembly, it answer material structure using " A " interlayer, and edge is solid core layer glass fibre reinforced plastic structure, is riveted after being glued with fixed edge strip, takes and passes through bolt again after airtight and watertight measure and connect with fuselage.
Description
Technical field:
The utility model belongs to aircraft totality Design of Aerodynamic Configuration field, is related to aircraft middle fuselage antenna house.
Background technique:
It is used according to the full machine antenna arrangement of aircraft, task and full machine EMC Design requires, aircraft is in machine
The antenna house that large-scale interferometric antenna arrays use is disposed at left and right sides of the rear portion of body middle section.Nothing is used during the radome design
Associated antenna it is conformal rectification, antenna part invaginate to multinomial totality such as fuselage, xyz three-dimensional optimal control contour lines pneumatically integrate it is excellent
Change design measure, reduces antenna house height to the maximum extent.Antenna shapes are carrying out parameter adjustment to control wheel profile and are adopting
It is calculated with CFD and prioritization scheme has been determined with after wind tunnel test verifying, preferred antenna cover is to aircraft drag incrementss less than 2%
(0.58%), local flow field characteristic is good.The antenna house shows to meet internal antenna task use demand through installation Flight.
Aerodynamic characteristic is excellent.
Summary of the invention:
1) the technical issues of solving
The purpose of the present invention is: optimization fuselage antenna house shape reduces influence of the antenna house to aircraft platform aerodynamic characteristic,
It is proposed a kind of fuselage side RECTIFYING ANTENNA cover.
The technical solution of the utility model is that antenna house uses integrated design, and the knot of fuselage is embedded in using two
Structure pressure-tight box is arranged in an antenna house as antenna mounting platform, by the interferometric antenna arrays of two onrelevants, guarantees antenna array
In the case where meeting layout, EMC Design requiring, close to fuselage appearance design, (shape is most in interferometric antenna arrays and cover as far as possible
Small―gap suture is only 30mm), while meeting the requirement at two antenna array difference wave transparent angles.Two are used in the configuration design of antenna house
Secondary curve passes through CFD as longitudinally, laterally generating the antenna house smooth-shaped transition of fairing streamline with lateral control line
Control line parameter is designed with wind tunnel test means.
2) technical solution
A kind of fuselage side RECTIFYING ANTENNA cover is arranged at left and right sides of middle fuselage rear portion, the long 1.89m of antenna house cover,
Wide 1.65m, thickness 0.44m, 3.29 ㎡ of wetted area, 0.42 ㎡ of front face area, antenna house coordinate system are to sit with antenna house First Point
Origin O to be marked, is positive after X axis, is positive in Y-axis, Z axis is positive to the left, it is chosen by following coordinate points, measurement unit mm:
All coordinate points are connected into spline curve and generate curved surface, form the aerodynamic configuration of antenna house.
3) beneficial effect
The utility model has the advantage that and beneficial effect, and the antenna house shape of the utility model passes through optimization design day
Irdome shape reduces the prominent fuselage appearance thickness of antenna house to the greatest extent, reduces aircraft aerodynamic drag increment, and to antenna house tail portion into
Row rectification, reducing antenna house wake flow influences aircraft, reduces the unfavorable interference to aircraft aerodynamic characteristic.

Specific embodiment
A kind of fuselage side RECTIFYING ANTENNA cover, wing antenna cover are long 1.89m, width 1.65m, thickness 0.44m, are with certain type machine
Example, antenna house are arranged in aft body.To reduce the prominent fuselage appearance thickness of antenna house, embedded combination pressure-tight box conduct is designed
Antenna mounting platform guarantees that two interferometric antenna arrays half are embedded in fuselage installation, greatly reduces the thickness of antenna house.In addition, examining
To consider antenna house maintainability and dismantles light requirement, it answers material structure using " A " interlayer, and edge is solid core layer glass fibre reinforced plastic structure,
It rivets after being glued with fixed edge strip, is connect again by bolt with fuselage after taking airtight and watertight measure.
The long 1.89m of cover, a kind of fuselage side RECTIFYING ANTENNA cover wide 1.65m, thickness 0.44m, 3.29 ㎡ of wetted area, is met
0.42 ㎡ of wind area, antenna house coordinate system are positive after X axis, are positive in Y-axis using antenna house First Point as coordinate origin O, Z
An axial left side is positive, and chooses by following coordinate points, measurement unit mm:
All coordinate points are connected into spline curve and generate curved surface, form the aerodynamic configuration of interference antenna house.
