Definitions
- the invention relates to a device for accelerating a projectile Use of a plasma generator and with distribution of a plasma arc in one Fuel mass.
- DE 44 40 829 A1 discloses an annular plasma injection device a fuel mass that has a supply connection for supplying a sufficient Possesses energy to generate a plasma and thereby a projectile accelerate in a gun barrel.
- This device has means for Directing the energy to a first and a second connection terminal and is set up to distribute a plasma arc in the fuel mass.
- the In this device energy is supplied via a so-called power supply rod, which is introduced centrally into the only fuel mass.
- the front one Part of the rod as an anode and the rear one arranged on the power supply Part of the rod is designed as a cathode.
- To the power supply rod there is a membrane-like element in a ring.
- this membrane-like element evaporates and sufficient Gas conductivity then enables the formation of a plasma between the front anode and the rear cathode in a ring around the Energy supply rod.
- the annular plasma arc develops accordingly along the energy supply rod.
- the resulting plasma is essentially stable and delivers a higher performance profile than that of a typical fixed ignition wire.
- the blowing agent components different geometries and different chemical compositions, to achieve the desired indoor ballistic behavior.
- Propellant components can be both conventional and also trade in LOVA blowing agents.
- the ignition of the fuel masses in the cargo space for example one Gun barrel, done via a plasma generator with very high effectiveness.
- An essential factor for the targeted ignition of the fuel mass or the propellant charge and thus for the control of indoor ballistic behavior forms the arrangement and design of the entire ignition unit.
- the plasma generator placed centrally in the first charge mass has decisive ones Advantages compared to conventional powder ignition.
- the Plasma generator releases radiation in a relatively large area, which means that the fuel mass is lit and overall a smooth burn-up curve can be seen.
- the plasma generator in the first or rear fuel mass there is a very even combustion of the Masses of fuel and therefore better and more even floor acceleration.
- the plasma generator 1 extends from the bottom 7 of the cartridge chamber 5 as a rod-shaped element centrally in the rear fuel mass 2.
- the plasma generator is in the usual way with a power supply connection 8 provided.
- the rear fuel mass 2 is in the form of a pot and filled as a bulk charge in the interior of the cartridge chamber 5.
- the pot-shaped fuel mass 2 has a relatively thick base area 9 and a relatively thin-walled cylinder region 10.
- the front fuel mass 3 or the propellant component 3 is rod-like trained and arranged radially around the projectile 4. This front mass of fuel 3 is compressed to a greater extent than the rear fuel mass 2.
- the fuel masses 2 and 3 are initiated via the plasma generator 1 with very high effectiveness. Due to the special arrangement of the plasma generator in the central rear area of the chamber 5, the two Fuel masses 2 and 3 ignited in a targeted manner, as a result of which the predetermined combustion behavior and thereby the internal ballistic behavior of fuel mass and projectile is reached. This means that an essential factor for targeted Ignition of propellant components 2 and 3 and thus for the control the arrangement and interpretation of the internal ballistic behavior Entire ignition unit from plasma generator 1 and fuel masses 2 and 3 forms. Burns when the rear fuel mass 2 is ignited by the plasma generator first the fuel mass 2 in parts. This increases the inner cargo space in which the fuel masses 2 and 3 are located. If this cargo space 2 increases due to the beginning of the burning of the rear Fuel mass 2, then the front fuel mass 3 is ignited, whose released energy is the energy of the fuel mass 2 for acceleration of the projectile effectively supported.
