Description
Technical field
The present invention relates to a kind of airborne increasing rain flame items.
Background technique
Increasing rain flame item, which burns to generate in aqueous cloud layer, increases rain catalyst, for realizing artificial rain operation.Existing increasing rain flame item
It is mainly made of shell, powder charge inner tube, electric igniter and forward and backward blanking cover, wherein shell is used to support protection installation internal each
Components；Powder charge inner tube is mainly made of outer layer protective sleeve and increasing rain catalyst；Electric igniter is led by electric firing part and two root longs
Line on rear blanking cover ring electrode and core pole collectively constitute；Front and back blanking cover is fixed inside the shell by powder charge inner tube, as shown in Figure 1.
By airborne flame item after the aircraft hanger, on aircraft hanger there are two contact pilotage respectively with the ring electrode of blanking cover after flame item and core pole structure
At discharge loop, when airborne flame console applies firing current to flame item, firing current flows through electric point by electrode and conducting wire
Fiery part, electric firing part generate thermal-flame after being under fire and light the increasing rain catalyst in powder charge inner tube, generate after catalyst combustion
Increase rain catalyst particle to spread with aircraft in aqueous cloud layer, completes artificial rain operation activity.
Existing flame item when leaving the factory, conductive metal foil is pasted generally between ring electrode and core pole and realizes short circuit, short-circuit
Purpose is to prevent unexpected electric current from flowing through electric firing part, makes electric ignition part accidental ignition, is a kind of common safeguard measure.True feelings
Condition is: before flame item is mounted on aircraft hanger, the conductive metal foil that will be pasted between the two poles of the earth being needed to remove, electric firing part is by short at this time
Line state is changed into open-circuit condition, and flame item is in the precarious position under various unexpected electric energy stimulations.Flame item is on airport simultaneously
And used in carrier aircraft, there are various electromagnetic radiation in environment, and extremely strong and complicated, for the flame item of open-circuit condition,
Longer two conducting wires of its length play the role of dipole antenna, and the antenna body of two conducting wire compositions absorbs RF energy, will
A large amount of charge can be had accumulated on conducting wire, be more easy to happen electrostatic breakdown effect in the bigger place of voltage field strength, lead to flame
Accidental ignition.Equally in the case where the short circuit of the two poles of the earth, two conducting wires form the structure of coil antenna, in electromagnetic field of high frequency
In, induced current is easily formed inside coil antenna, in the higher electromagnetic field of frequency, induced current is bigger.In recent years
There is a phenomenon where flame item occur accidental ignition aboard, analyze its reason, with electromagnetic environment it is more and more severe, add flame
Item itself does not have the ability of anti-electromagnetic-radiation.
The igniting sequence of existing flame item is that electric ignition part is under fire under electrocaloric effect, generates flame or high temperature refires igniting
Pack (item, box) discharges thermal-flame in combustion, scorching hot particle is transmitted to by sustained combustion after igniter pad ignition
Pipe surface in powder charge, the heat transfer the effects of under light catalyst powder charge in powder charge inner tube.In practical applications, electric ignition part
It is plane contact with powder charge inner tube, while in aircraft operation, flame item is in the hypobaric environment of altitude low temperature, once before breaking
Diaphragm seal on blanking cover, thermal-flame, the scorching hot particle that igniter pad burning generates will quickly be sucked out flame item, if at this time
Catalyst powder charge is under fire not yet, and due to the disappearance of ignition energy, catalyst powder charge will not burn, and will lead to loss of ignition.
Diaphragm seal break opportunity to be related to factor more, for igniting, using the biggish ignition charge of gas production as igniter pad
When main charge, the thermal-flame that ignition charge burning generates is conducive to light catalyst powder charge, but is more advantageous to and breaks diaphragm seal,
When igniter pressure can be allowed bigger diaphragm seal thickening, it is possible to cause catalyst powder charge that hypervelocity reaction occurs under high pressure, sternly
Explosive reaction can occur when weight, jeopardize carrier aircraft safety.If the high-temp solid residue that ignition charge generates is less, in electric firing part and
In the case that catalyst powder charge is not close contact, the heat generated after ignition charge burning cannot be transmitted to catalyst table well
Face can not preferably complete igniting task.I.e. upper described, flame item is defective in the fiery sequence design of biography at present, reliability of lighting a fire
Index is only 90%, is matched with actual flame misfire rate.
Ring electrode and core pole material after existing flame item on blanking cover by the preferable copper metal material processing of electric conductivity and
At copper metal surface in the case where unprotected easily generates one layer of non-conductive oxidation film, will seriously affect ring electrode
With the electric conductivity of core pole and aircraft hanger.
Summary of the invention

Open hole in preceding blanking cover center；A capacitor of releasing is connected between the positive and negative electrode of the electric igniter, and connects the conducting wire at the two poles of the earth
On magnet ring is installed；The powder charge is provided with groove close to the end face of electric igniter, and the ignition charge of the electric igniter is seated in
In groove, and it is open with combustible material closed pockets；The ignition charge includes the metal that mass percent is 55~80% can
Agent and mass percent are fired for 20~45% oxidant, and the sum of metal fuel agent and the mass percent of oxidant are 100%.
The metal fuel agent is zirconium powder or zircaloy；The oxidant selects Pb2O3。
The electric igniter utilizes screen printing technique assist side using wiring board substitution copper ring electrode and core pole
Copper is covered in the position of upper corresponding aircraft hanger contact pilotage, and carries out tin plating protection to copper is covered.
The beneficial effects of the present invention are:
1, by increasing capacitor of releasing (typical capacitance is 50V mica capacitor, 0.015 μ F of capacity C), the two poles of the earth can be taken precautions against and existed
Impact of static electricity on human body's (25000V, connect 500 Ω) to ignition part under open-circuit condition.
2, release capacitor and magnet ring inhibit jointly and energy consumption effect under, can be to 30kHz~100MHz, field strength 50V/m
