Abstract
The utility model belongs to Design of Aerodynamic Configuration field, it is related to a kind of Combined design forward antenna cover, transition flow line design method is merged with plane nose by using big, small two kinds of antenna house Combined designs and antenna house shape, under the premise of meeting task system requirement, it effectively controls antenna house outer dimension and air-flow flows through the separation occurred when antenna house, reducing attaching antenna cover influences the aerodynamic characteristic of carrier aircraft.
Description
Technical field:
The utility model is related to the shape of aircraft forward antenna cover, belongs to aircraft totality Design of Aerodynamic Configuration field.
Background technique:
" a kind of " Combined design forward antenna cover " Disclosure of invention " discloses a kind of the outer of Combined design forward antenna cover
Shape.Needs are installed according to task system, aircraft need to install large-sized forward antenna cover additional in head, install the antenna house pair additional
Resistance, longitudinal moment and the course torque of carrier aircraft etc. aerodynamic characteristic have an impact, in order to guarantee that aircraft has good gas
Dynamic characteristic, preferably flying quality and flight quality need as far as possible under the premise of meeting task system mission and operational exertion requirement
Reducing the nose shell installed additional influences carrier aircraft aerodynamic characteristic.
Summary of the invention:
(1) goal of the invention
It is pneumatic to full machine to minimize the machine for casing-in or applying cover to book previous day irdome under the premise of meeting antenna requirement for the utility model
The influence of characteristic proposes a kind of design of forward antenna cover.
The technical solution of the utility model is that aerodynamic configuration, antenna have been fully considered in antenna house configuration design
Electrical property, structure space, cockpit visual field, the antenna rotation enveloping space, gap of antenna and antenna house etc. require, using one
Greatly, small two kinds of antenna house Combined designs and antenna house shape merge transition flow line design method with plane nose, are meeting
Under the premise of task system requirement, effectively controls antenna house outer dimension and air-flow flows through point occurred when antenna house
From reducing attaching antenna cover influences the aerodynamic characteristic of carrier aircraft.
(2) technical solution
It using antenna house forward terminal as coordinate origin O, is positive after X axis, is positive in Y-axis, Z axis meets left hand rule, closes
It is symmetrical in XOY plane, 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 forward antenna cover.
(3) beneficial effect
The beneficial effects of the utility model are: the antenna house shape of the utility model, uses in antenna house configuration design
One big, small two kinds of antenna house Combined designs and antenna house shape merge transition flow line design method with plane nose, full
Under the premise of sufficient task system requirement, effectively controls antenna house outer dimension and air-flow flows through point occurred when antenna house
From reducing attaching antenna cover influences the aerodynamic characteristic of carrier aircraft.Verification result shows: relative to carrier aircraft, the antenna house is to resistance
Power influence amount is within 0.4%.To course torque influence amount within 1.4%.
Detailed description of the invention
The attached drawing of the utility model has 2, and Detailed description of the invention is as follows:
Fig. 1 is that a kind of Combined design forward antenna cover is bowed perspective view；
Fig. 2 is a kind of Combined design forward antenna cover lateral projection schematic diagram.
Specific embodiment
A kind of Combined design forward antenna cover, by using big, small two kinds of antenna house Combined designs and antenna house
Shape merges transition flow line design method with plane nose, under the premise of meeting task system requirement, effectively controls
Antenna house outer dimension and air-flow flow through the separation occurred when antenna house, reduce attaching antenna cover to the aerodynamic characteristic shadow of carrier aircraft
It rings.Using antenna house forward terminal as coordinate origin O, it is positive after X axis, is positive in Y-axis, Z axis meets left hand rule, about XOY
Plane is symmetrical, 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 forward antenna cover.
Claims (1)
1. a kind of Combined design forward antenna cover, it is characterised in that: using antenna house forward terminal as coordinate origin O, be after X axis
Just, it is positive in Y-axis, Z axis meets left hand rule, and symmetrical about XOY plane, according to the form below coordinate points are chosen, measurement unit mm:
All coordinate points are connected into spline curve and generate curved surface, form the aerodynamic configuration of forward antenna cover.
