Description
Technical field:
The utility model belongs to overall Design of Aerodynamic Configuration field, is related to outside aircraft vertical tail wing tip antenna house
Shape.
Background technique:
A kind of ESM antenna is installed on vertical tail top by task system by certain type machine, is protected by design RECTIFYING ANTENNA cover
Demonstrate,prove the installation and use of antenna.Since the envelope size of certain type machine vertical tail wing tip antenna house is small, other model task systems
Antenna installation can not continue to use its form.According to the installation of certain new model task system receiving antenna, field of view of receiver angle index, carrier aircraft
Plan as a whole arrangement etc. with task system antenna electromagnetic compatibility to require, needs to be located at 15 rib top of aircraft vertical empennage top and task is installed
System antenna.It installs the antenna house additional to have an impact the resistance of carrier aircraft and lift coefficient etc. aerodynamic characteristic, in order to guarantee to fly
Machine has good aerodynamic characteristic, preferably flying quality and flight quality, is meeting task system mission and operational exertion is wanted
Under the premise of asking, antenna house shape need to be rationally designed, the antenna house for minimizing installation influences carrier aircraft aerodynamic characteristic.
Summary of the invention:
1) the technical issues of solving
The purpose of (utility model) of the invention is: cooperating full machine electromagnetic compatibility planning to consider task system antenna arrangement, mentions
A kind of reasonable antenna house configuration meets task system antenna for antenna and installs and uses out, reduces the vertical fin wing tip antenna house of installation
Aircraft aerodynamic characteristic is influenced.
The technical solution of (utility model) of the invention is:
The aircraft vertical empennage wing tip antenna house that (utility model) of the invention is related to is located at airframe vertical tail top
15 rib tops carry out total cover rectification and protection, maximum limit to integration servers system large-scale antenna battle array with the streamlined contour of fairing
Degree ground reduces size, the weight of antenna array, reduces the ruler of the prominent fuselage appearance of fuselage ultra-large type RECTIFYING ANTENNA cover to the maximum extent
Very little, antenna house middle section is about the straight sections such as the cylinder circular arc of long 1530mm；Front and back is to symmetrical half ball component for radius 335mm.
To meet the requirement of task system field angle, antenna is arranged in vertical tail top it is possible to prevente effectively from being arranged in machine
Other region bring antenna upward angle of visibilities of body and downwards angle of visibility are unable to satisfy the influence of military success index request.Before and after antenna house to for pair
Claim hemisphere design, the signal that the smooth transition of shape curvature is conducive to task system antenna detects receipts, while being its internal antenna
Configuration design, enhancing signal gain provide the foundation.
Transition streamline is merged with vertical tail using antenna house shape in the layout designs of vertical tail wing tip antenna house
Design method separates when air-flow being avoided to flow through antenna house, improves air velocity distribution.Before meeting task system requirement
It puts, minimizes the outer dimension of antenna house.
2) technical solution
A kind of vertical tail wing tip antenna house shape, in 15 rib top of airframe vertical tail top, antenna house
The straight sections such as the cylinder circular arc of Duan Yuewei long 1530mm；Front and back is to symmetrical half ball component for radius 335mm.With antenna house along course
The intersection point of symmetrical plane and antenna house symmetry axis is coordinate origin O, is positive after X axis, is positive in Y-axis, and Z axis is positive to the left,
See Fig. 1, Fig. 2, chooses coordinate points design molding, measurement unit mm.Vertical tail antenna house coordinate points are shown in Table 1.
1 vertical tail antenna house coordinate points of table
The data punctuate of antenna house installation transitional region and antenna house coupling part presses selection, is shown in Table 2.
2 vertical tail antenna house join domain coordinate points of table
All coordinate points are connected into spline curve and generate curved surface, form the pneumatic outer of vertical tail wing tip antenna house
Shape.
The vertical tail wing tip antenna house is detachable.
3) beneficial effect
The utility model has the advantage that and beneficial effect, and opposite carrier aircraft platform, aircraft Lateral static stability mentions
Height is mainly due to installing vertical tail wing tip antenna house bring additional.Vertical tail wing tip antenna house makes the horizontal course static-stability of full machine
Property change greatly, directional static stability increase about 17.3%, Lateral static stability increase about 6.11%, minimum drag coefficient increase
About 1.57%.Vertical tail wing tip antenna house changes the pressure distribution of vertical fin wing tip, increases effective aspect ratio of vertical fin, together
Shi Zishen produces certain cross force and the relative CG arm of force is larger, and full machine C is made under comprehensive functionlβIt dramatically increases.Comprehensive function
Under dramatically increase full machine Lateral-directional static stability.
Vertical tail antenna house configuration can effectively reduce antenna array enormous size and caused by design, assembly difficulty, reduce
Influence of the task system antenna house to whole machine weight, aerodynamic characteristic and flight quality.
Detailed description of the invention:
The definition of vertical tail wing tip antenna house coordinate system: antenna house is along course symmetrical plane and the intersection point of antenna house symmetry axis
For coordinate origin O, it is positive, is positive in Y-axis, Z axis is positive to the left after X axis.
Fig. 1 is that vertical tail wing tip antenna house overlooks coordinate system definition figure
Fig. 2 is vertical tail wing tip antenna house side view coordinate system definition figure
Fig. 3 is vertical tail antenna house main view
Fig. 4 is vertical tail antenna house along course side view
