A. antenna
The aircraft of such as aircraft etc is compared due to being to fly in the air, therefore with general means of transport with machinery
It is very different in structure.Each part of aircraft is required while disclosure satisfy that structural strength and rigidity as far as possible
Gently.By taking wing as an example, wing is the critical piece for producing lift, it is therefore desirable to bears very big load, this needs wing to have
Good structural strength will also play the role of very big rigidity and ensure wing in substantial load to bear this huge load
Under will not too deform.The basic primary structure member of fuselage includes skeleton and housing etc..
Housing is the dimension shape component being enclosed in outside fuselage framework, is fixed on bonding agent or rivet on skeleton, forms aircraft
Aerodynamic shape, with good aerodynamic characteristics.Housing except formed and maintained fuselage aerodynamic shape it
Outside, it is also necessary to bear aerodynamic effect and active force is delivered to connected fuselage wing skeleton.In addition housing directly with outside
Contact, it requires that case material has that intensity is high, plasticity is good, the characteristic such as anticorrosive.The housing of early stage dopey is cloth
Matter, then aircraft housing uses alloy shell more, and aircraft has started to use carbon fiber composite materials at present.
It is used to manufacture housing the invention provides a kind of new modified cyanate ester resin, and antenna is combined with body shell
Get up.Preferably, the invention provides a kind of logarithm period oscillator array antenna, and the logarithm period oscillator array antenna is formed
Surface of shell or inside are combined together with housing.Housing is antenna, and antenna is housing, can bear the one of load, referred to as body
Part can be used for distant early warning as antenna again.The antenna of the present invention three-dimension curved surface complicated with body combines together, from
And realize conformal with body.Using the conformal antenna of the present invention, the shortcomings that linear array peace planar array scanning angle can be overcome small,
It can realize that full spatial domain electricity is swept to perceive with omnidirectional, thoroughly avoiding conventional airplane needs very large radome and be individually for antenna peace
Dress arrangement thrust, eliminates the adverse effect brought to aircraft aerodynamic performance.
Fig. 2 is the schematic diagram for the structure for showing logarithm period oscillator array antenna according to an aspect of the present invention.Such as figure
Described, logarithm period oscillator array antenna 200 includes multiple oscillators, and the distance between these oscillator sizes and oscillator have determination
Proportionate relationship.If representing the proportionality coefficient and referred to as scale factor with τ, meet：

Distance all at equal pace coefficient τ changes between width, eccentric distance and oscillator：
（Formula 3）
The distance between adjacent vibration generators are represented with interval factor δ in practice, interval factor δ is defined as between adjacent vibration generators
Distance dnWith the total length 2L of 2 times of longer oscillatorsnThe ratio between, i.e.,
（Formula 4）
α in Fig. 2 is referred to as the drift angle of logarithm period oscillator array antenna, and it has following relation between τ and δ：
（Formula 5）
（Formula 6）
The distributing point of the logarithm period oscillator array antenna is selected at most short oscillator.The greatest irradiation direction of antenna will be by most growing
The oscillator end most short oscillator direction of direction.Geometrical structure parameter τ, δ and α have emphatically to the electrical property of logarithm period oscillator array antenna
The influence wanted.The electrical characteristics such as the impedance operator of antenna, directional characteristic are all the functions of the electric size of antenna.If two width antennas
Geometry is similar, and the proportionality coefficient of size is τ, and as the proportionality coefficient also τ of working frequency, then this two width antenna has identical
Electrical characteristics.Based on the principle, the electrical characteristics such as the input impedance of logarithm period oscillator array antenna and directionality press the logarithm of frequency
It is repeated cyclically.In practice, the radiation area of antenna can move forward and backward on antenna and keep similar electrical characteristics, thus right
One number time, oscillator array antenna had very wide frequency band.

To mould and assembled mould.Formpiston article inner surface size accurate smooth, program is convenient, is easy to divulge information.Former article inner surface chi
Very little accurate smooth, but inconvenience is operated, ventilation condition is poor.Mould is made up of matched molds two parts, product surfaces externally and internally is smooth,
The degree of accuracy is high, but uncomfortable synthesis type discloses few and large-scale product.Assembled mould is that mould is divided into several pieces to carry out assembly, so as to
It is convenient in demoulding, is adapted to complex-shaped product.In practice, selected according to factors such as the shape for the housing to be formed, sizes
Suitable mould.
This multilayer prepreg being laid on mould is cured shaping by moulding process.In this way, in temperature, time
The predetermined shape of multilayer prepreg is fixed up with the influence of the factor such as pressure, forms the composite wood with predetermined shape
Material shell body.In one embodiment, this multilayer prepreg is heated, makes its shaping.More preferably, add to this multilayer prepreg
While hot, also this multilayer prepreg is pressurizeed.For example, it can connect laying into prepreg uncured after predetermined shape

Functional resin matrix.It is its relatively low dielectric constant (2.6-3.4) and dielectric loss angle tangent value (0.003-0.009), heat-resisting/wet
Hot property (- 260 DEG C), good comprehensive mechanical property and moulded manufacturability are allowed to as dielectric function composite resin base
Body gets most of the attention in the application of Aeronautics and Astronautics and electronics industry.However, after being polymerize due to cyanate ester resin (CE) monomer
The big of crosslink density adds triazine ring structure high degree of symmetry in molecule, causes cyanate ester resin (CE) solidfied material more crisp, and fracture is strong
The problems such as degree, poor toughness, as structure (especially main stress structural material) in use, its toughness can not usually meet to require,
Limit promoting the use of for cyanate ester resin (CE resins).For the application of developing cyanate ester resin (CE resins), people adopt
Take various methods to be modified it, improve intensity and toughness.The method of common modification includes thermosetting and thermoplastic resin modified
