In order to increase a service life of a microwave generator, a resonator configuration for a microwave generator has a hollow cylindrical electrical conductor positioned inside a housing, a first electrode, and a second electrode. Two electrodes are spaced apart from one another and form a spark gap in the region of the conductor. A contact element is provided for making electrical contact between the conductor and the first electrode. The position of the first electrode can be adjusted to modify a length of the spark gap. Furthermore, the contact element is electrically connected to the first electrode or its holder so as to resist movement so that the opposing contact surfaces remain in contact even when the position of the first electrode is adjusted with respect to the second electrode. The contact element is configured to be deformable, preferably elastically deformable, for this purpose.

Resonator configuration for microwave generator

A microwave generator, which includes a housing having two mutually opposite electrodes which are separated via an electrode intermediate space which is filled with a dielectric, and with the electrodes having a spark gap between them, which breaks down in order to emit microwaves when a high voltage is applied. The electrode intermediate space () can be at least partially filled with a second dielectric (), which has a different dielectric constant compared with that of the first dielectric () which is located between the electrodes () in order to vary the microwave frequency, whereby the second dielectric () is held in a reservoir () which communicates with the electrode intermediate space ().

Microwave generator

A microwave generator having a central electrode () which at the front end has a radiating element () and an external electrode () which coaxially surrounds the central electrode () along an axially extending resonator portion (), wherein the two electrodes (and) are of a rotationally symmetrical configuration and define a spark gap () which sparks across when a high voltage is applied and radiates microwaves by way of the resonator portion () and the radiating element () of the central electrode (). The spark gap () is in the form of an annular spark gap, which is determined by a connection element () which projects at the rear end axially centrally away from the central electrode () and an annular edge () of the external electrode (), the edge being provided coaxially with respect to the connection element (). The central electrode () and the external electrode () are arranged in a housing sleeve () of an electrically insulating material. The housing sleeve () preferably has an extension () defining a space () in which there is arranged a high voltage source (), which is electrically conductively connected to the electrodes (and) of the microwave generator ()

A microwave generator () has a parallel connection of series connections of uncontrolled discharge spark gaps () and charge storage means () which are charged up by way of charging resistors () and an inductor () common to all parallel connections, from a high voltage generator (), until the respective spark gaps () short-circuit by way of arcs and the storage means () are discharged again by way of the inductor (). The oscillating short-circuit currents which thus occur in stochastic steep-edged manner and which are superimposed on each other in the inductor () are emitted by way of an antenna () connected in single-pole manner thereto in the form of a high-energy microwave spectrum which is wide-band in accordance with the arc switching speed, with a spectral key point which is determined by the inductor (). Such an operative system which can be used as a non-lethal interference or jamming device in relation to communication connections and in relation to the function of electronic circuits can be embodied in the size of a manually portable case or also in the form of a payload for a submunition projectile, a rocket or a drone and can thus be used over a wide operative range.

The superimposition of the microwave fields of an array () of microwave generators (), with self-firing spark gaps () for the discharge of storage devices (), which are charged up to a high voltage, results in an increase in field strength and a capacity for influencing the frequency spectrum of the emitted high-energy high-frequency field and the emission direction thereof.

Intensive microwave radiation in particular of great band width and energy over a relatively long period of time in the form of long pulse packets with a high pulse repetition frequency and a very high frequency spectrum can be achieved if microwave irradiation is effected during the discharge of a capacitive high-voltage generator () by way of the antenna () into a series of successive capacitors () to be connected in parallel. They are preferably constructed in the form of a concentric stack, connected to the antenna (), of which the outer electrodes () which are at a reference potential are in the form of a continuous tube within which annular electrodes () are disposed on a carrier () in axially spaced relationship with each other in such a way that at the same time they act as the electrodes of arc switches () for successively switching on subsequent capacitors (). The switch response characteristics and the charging time constants of the capacitor () which is respectively switched on therewith and the number thereof determine the length of the packet of high-frequency individual pulses () and thus the radiated microwave energy which can be still further increased by an increase in the capacitance of the capacitors ().

Microwave generator and method of radiating microwave energy

A very compact interference frequency generator () which emits with an extremely wide band width and extremely powerfully is afforded by the combination of a mechanical pulse generator () with two piezoelectric pillars () which are disposed axially in succession and which can be axially acted upon by the pulse generator () and which are electrically connected in series in opposite relationship and which are electrically conductively connected with their mutually remote ends () to electrodes () which extend parallel to the piezoelectric pillars () to an electrically conductive coupling portion () between the piezoelectric pillars () where they end as electrodes () of an axial spark gap and at the same time spark gaps () which are oriented inclinedly radially towards the coupling portion ().

High voltage generator, especially for using as a noise frequency generator

For a compact microwave generator ( ) with powerfully wide-band microwave radiation in which there is a marked resonance increase whose frequency center of gravity is variable in order to be able to adapt the power center in respect of the radiated wavelengths to the geometrical structure of a circuit configuration to be disturbed, a conductor ( ) which coaxially surrounds the spark gap ( ) between the electrodes ( ) is electrically connected to one of the two electrodes ( ) mechanically adjustably in its effective length as a variable resonator.

Described is a rudder blade mounting arrangement ( ) for a missile comprising a rudder blade ( ) and a mounting element ( ) for the rudder blade. The rudder blade ( ) is displaceable about a rudder blade axis member ( ) of the mounting element ( ) between a retracted inactive position and a deployed active position. The rudder blade foot ( ) of the rudder blade ( ) is connected in positively locking relationship to the rudder blade axis member ( ) in such a way that, in the deployed active position of the rudder blade ( ), the rudder blade foot ( ) is forced against a front face ( ) of a side portion ( ) of the mounting element ( ). In the retracted inactive position the rudder blade foot ( ) is spaced from said front face ( ) by the positively locking connection and the rudder blade foot ( ) is thus axially limitedly movable with the rudder blade axis member ( ) in relation to the mounting element ( ) so that the rudder blade ( ) is freely displaceable from the retracted inactive position into the deployed active position.
