Abstract
The utility model relates to an airborne radome equipped with a self-balance air pressure function. The airborne radome comprises a radome made of cellular core sandwich materials. The radome is in a helmet shape. More than two waterproof gas vents are arranged on the two sides of the radome vertically to a flight direction. Through the waterproof gas vents arranged on the radome, rain is prevented from invading a radar cover and also internal environment and external environment of the cover body is communicated, hence air pressure difference in the radome and out of the radome is balanced. Waterproof exhaust pre-embedded blocks are arranged on the two sides of the operation direction of the radome. The waterproof gas vents are arranged on the pre-embedded blocks, hence on one hand, air-flow is prevented from directly acting on a steam vent surface when an airplane flies in a high speed, and on the other hand, interference of the metal pre-embedded block on a radar antenna is prevented.
Description
Technical field
The utility model belongs to airborne radar technical field, is specifically related to the radome of the airborne radar antenna that is applicable to the type such as helicopter, unmanned plane.
Background technology
Because airborne radar is mounted on airframe, and be the outside in cabin, so airborne radar antenna must have the protection of radome.But be in different height above sea levels owing to taking off state and state of flight, aircraft is in the time of high speed flight at high altitude, and cover body is outward hypobaric, the interior still ground pressure of cover body, inside and outside cover body, will produce larger pressure difference like this, may produce adverse influence to radome.And the high-speed flight of aircraft also can be to producing larger pressure differential inside and outside radome.This not only can cause larger impact to radar antenna system, and the performance of radar is damaged, and even also can have influence on the flight safety of aircraft.
Summary of the invention
For the protection to airborne radar antenna better, by the improvement to radome, the utility model provides a kind of airborne radome with self-balancing air pressure function.
The airborne radome with self-balancing air pressure function comprises a radome of being made up of cellular sandwich material, and described radome is steel helmet shape, offers respectively two above Water-proof exhausting holes perpendicular to two side lower parts of the radome of heading; Two side lower parts perpendicular to the radome of heading are respectively equipped with tabular pre-embedded block, offer two above Water-proof exhausting holes that connect radome on described pre-embedded block.
Described Water-proof exhausting hole is low inside and high outside inclined hole, and angle between horizontal plane is 30～45 degree.
The thickness of described pre-embedded block is identical with the material thickness of radome, is coated between the interior exterior skin of radome, forms complete, a smooth entirety with radome.
The diameter in described Water-proof exhausting hole is 5～8 ㎜.
Useful technique effect of the present utility model embodies in the following areas:
1. by design Water-proof exhausting hole on radome, both prevented from, in rainwater intrusion radome, can be communicated with again the internal and external environment of cover body, thereby balancing antenna cover inner and outer air pressure being poor;
2. Water-proof exhausting pre-embedded block is embedded in to two sides in radome operation course, the thickness of pre-embedded block is identical with honeycomb interlayer, be coated between the interior exterior skin of radome, form complete, a smooth entirety with radome, and Water-proof exhausting hole is opened in to pre-embedded block, while avoiding aircraft high-speed flight on the one hand, air-flow acts directly on steam vent face; On the other hand, avoided the interference of metal pre-embedded block to radar antenna.
