Description
FUSE SYSTEM THAT CAN HARVEST ENERGY FROM ENVIRONMENTAL CONDITIONS
Technical field of the invention
This invention relates to a system that harvests the energy of the electronic units used in fuse systems by using the separate environmental conditions.
Particularly, the invention relates to a system that can harvest its own energy and makes all required functions of the fuse work by operating its additional sensors without requiring outer sources.
State of the Art
Today, there are fuses using reserve chemical batteries. Reserve chemical battery is activated by a mechanical system driven by using the axial acceleration and spin formed during the flight and produces electrical energy. Reserve batteries and thermal batteries are products with shelf life. They are also affected by the climate conditions of the region where the ammunition will be used. This fact causes very severe problems during operation. In the cases where the day time temperature average of the region’s geography is high, ammunition fuses using chemical reserve batteries overheat and become impossible to be used in operations. Replacing these batteries cannot be made since it is a very challenging procedure.

In the systems of the prior art, using materials sensitive to environmental conditions in fuse systems poses a risky situation.

Description of the invention
This invention relates to a system that harvests the energy of the electronic units used in fuse systems by using the separate environmental conditions. The fuse (100) comprises piezoelectric generator (110), thermoelectric generator (120), switch (130), controller unit (140), spring (150) and super capacitor (160).
The fuse (100) controls the explosive chain exploding the warhead on the rocket or missile and ensures that it is safely stored before the launch and is exploded at the desired time after the launch. The fuse (100) ensures that it harvests its own energy independently and makes all required functions of the fuse work by operating its additional sensors without requiring outer sources. The fuse (100) provides the electric energy required for the electrical units used in electromechanical or electronic fuses. The fuse (100) uses two separate environmental conditions to make the explosive chain ready and aligned by sticking to the standard requirements in the ammunition fuse designs.
The spring (150) provides the compression with the axial acceleration formed during the launching of the ammunition from the barrel or thrust force created by rocket/missile motor.
Piezoelectric generator (1 10) enables the production of the short-time low extent electric energy by means of free vibration formed in a mass-spring (150) mechanism compressed by the axial acceleration formed during the launching of the ammunition from the barrel or thrust force created by rocket/missile motor.
Thermoelectric generator (120) produces electric energy from the temperature difference between the outer surface and inner environment of the fuse (100) created by the heating formed as a result of the aerodynamic friction and/or rocket/missile engine during the flight of the ammunition. Thermoelectric generator (120) provides energy as the main energy source of the electronic circuits within the fuse (100). Thermoelectric generator (120) comprises Peltier (thermoelectric cooling) modules and ensures that the cold faces of the modules remain cooler than the ammunition body all the time by means of thermally adhesive materials with high heat capacity.
The switch (130) is controlled by controller unit (140) and operates the ignition circuit. The switch (130) is activated first by the electric energy produced by the piezoelectric generator (130). This energy keeps the switch (130) circuit active until energy harvesting from the thermoelectric generator (120) begins. Then, when electric energy is produced from the thermoelectric generator (120), the task of the piezoelectric generator (1 10) ends, and the switch (130) is kept active with the energy provided by the thermoelectric generator (120). Unless an input is generated from the piezoelectric generator (1 10), the energy produced from the thermoelectric generator (120) cannot activate the switch (130). By this way, it is ensured that the fuse (100) complies with the two separate environmental conditions of the safety specified in the standards.
The super capacitor (160) enables the energy produced from the thermoelectric generator (120) to be stored. The stored energy provides energy to a controller unit (140), additional sensors and ignition circuit for the fuse (100) to perform its task. Additional sensors measure the values such as the acceleration of the ammunition and angular speed, and transfers these data to the controller unit (140) on which they are controlled. By this way, functions such as target detection, impact detection or electronic arming are operated by the energy produced from the thermoelectric generator (120).
The controller unit (140) activates the switch (130) by determining that it meets the conditions required for the activation of the fuse (100) by sticking to the amount of the electric energy production and the order of the energy production of generators. The controller unit (140) firstly enables the activation of the switch (130) when electric is produced from the piezoelectric generator (110). The controller unit (140) provides the energy required by the ignition circuit for the ignition of the ammunition from harvested energy. The controller unit (140) firstly ensures that potential errors are prevented by determining that it is not a flight in the case that there is no input from the piezoelectric generator (110), if electric energy is produced from thermoelectric generator (120) due to heating.
The system that is the subject of the invention is initiated by launching of the ammunition or the operation of the rocket/missile engine. The piezoelectric generator
(110) produces energy by means of free vibration formed in the spring (150) mechanism compressed by the axial acceleration formed during the launching of the ammunition from the barrel or forming thrust with rocket/missile motor and the thermoelectric generator (120) produces energy from the temperature difference between the outer surface and inner environment of the fuse (100) created by the heating formed as a result of the aerodynamic friction and/or rocket/missile engine during the flight of the ammunition. This produced energy is stored by super capacitor (160). Then, the controller unit (140) begins to operate, and the super capacitor (160) energises the super capacitor (160), the controller unit (140) and the additional sensors. The controller unit (140) enables the activation of the switch (130) that operates the ignition circuit by confirming the installation conditions as first the piezoelectric generator (110) producing energy and then the thermoelectric generator (120) produces energy. After this, the target is detected and explosion is performed.
