Description
Technical field
The utility model is related to aerospace field, it particularly relates to which a kind of have high wave-penetrating composite material antenna thunder
Up to cover.
Background technology
As important wave transparent component, antenna radar cover is normally at Vehicle nose, mostly taper or hemispherical, it was both
It is the structural member of aircraft, and is the important component of radio homing guidance system.
During aircraft flight, antenna radar cover should bear the adverse circumstances such as aerodynamic loading, Aerodynamic Heating, make again
To emit and receiving the channel of electromagnetic wave, ensure the normal transmission of signal, so as to which aircraft be made to smoothly complete the tasks such as guidance.This
Outside, in order to reduce Vehicle nose's aerodynamic drag, antenna radar cover can protect guidance, communication, telemetering, ignition of aircraft etc.
System works normally in harsh environments, and a kind of to integrate carrying, water conservancy diversion, wave transparent, solar heat protection, anti-corrosion etc. multi-functional
Structure/functional component.With the continuous improvement of aircraft Mach number, in missile aerodynamic power and Aerodynamic Heating maximum extreme higher position
The temperature and thermal shock that antenna radar cover is subjected to are higher and higher.
For the reentry velocity of tactical flying device of new generation up to more than ten Mach, this causes the work of aircraft antenna radar cover
Environment is increasingly severe, its heat resistance of previous antenna radar cover is poor, and intensity is low, and quality is big, and deformation easy to aging is not suitable for making
Make the wave transparent component of High Mach number aircraft.
For example, Chinese Patent Application No. 201620037749.8 discloses a kind of protective cover for radar antenna, it is wrapped
Include rectangular base and the hollow glass steel panel on rectangular base central axes, the middle control glass protecting plate and rectangular base
It intersects vertically and is connected together.The beneficial effects of the utility model are to be placed in radar antenna in hollow glass steel panel and the external world
Isolation, since fiberglass will not have shielding action to the signal of radar antenna, in the normal use for not influencing radar antenna
Under the premise of to radar antenna provide physical protection, radar antenna is avoided to be exposed to wind and rain by the external world, so as to extend radar day
The service life of line.But the structure of the utility model cannot be used for high Mach aircraft radars antenna protection cover, and quality
It is bigger.
