Antecedentes de la invención Background of the invention
El disparo del mortero que va montado sobre un vehículo produce fuerzas de reacción muy elevadas y en un corto periodo de tiempo, que se aplican sobre el propio vehículo. El impacto de dichas fuerzas provocaría graves daños en el vehículo, especialmente en su sistema de suspensión. Para mitigar parcialmente el efecto de estas fuerzas de reacción, este tipo de sistemas llevan un recoil absorber (amortiguador de retroceso). The firing of the mortar that is mounted on a vehicle produces very high reaction forces and in a short period of time, which are applied to the vehicle itself. The impact of these forces would cause serious damage to the vehicle, especially its suspension system. To partially mitigate the effect of these reaction forces, these types of systems have a recoil absorber (recoil damper).
En las operaciones militares el objetivo es disparar a un blanco enemigo y luego alejarse lo más rápidamente posible del punto de disparo inicial, para lo cual es crucial contar con un sistema portamorteros embarcado en un vehículo que pueda desplegarse y replegarse fácil y rápidamente. In military operations the objective is to shoot at an enemy target and then move away from the initial firing point as quickly as possible, for which it is crucial to have a mortar carrier system mounted on a vehicle that can be deployed and retracted easily and quickly.
Comparado con los sistemas que disparan desde el vehículo el disparo desde el suelo trae ventajas significativas: Compared to systems that fire from the vehicle, firing from the ground brings significant advantages:
- Menor coste inicial del vehículo, pudiendo el sistema que dispara desde el suelo ser integrado en vehículos ligeros comerciales, que no necesita ser un vehículo militar de gran envergadura y reforzado para aguantar las fuerzas del disparo. - Lower initial cost of the vehicle, since the system that fires from the ground can be integrated into light commercial vehicles, which do not need to be a large military vehicle and reinforced to withstand the forces of the shot.
- Menor coste en mantenimiento, al ser un vehículo comercial más simple y con piezas de reposición disponibles en el mercado, que permanece aislado de las fuerzas de reacción del disparo. - Lower maintenance costs, as it is a simpler commercial vehicle with replacement parts available on the market, which remains isolated from the reaction forces of the shot.
Alcance máximo del mortero/munición. Al disparar con cargas máximas, la fuerza de reacción del disparo es parcialmente absorbida por el amortiguador de tiro, con el remanente de estas fuerzas afectando directamente al vehículo El documento EP 0906553 A1 se refiere a un arma de fuego de ángulo elevado, en particular un lanzagranadas, y describe un cañón de tiro curvo que comprende, al menos, un tubo de arma regulable pivotante, un mecanismo de ajuste para la regulación del tubo y un dispositivo de orientación para el mecanismo de ajuste a fin de dirigir los tubos de arma con el objetivo de garantizar un campo de orientación amplio con un manejo sencillo. El dispositivo de orientación presenta un aparato de orientación independiente, dispuesto preferentemente separado del mecanismo de ajuste, por medio del cual es posible activar el mecanismo de ajuste para la orientación lateral y de altura de los tubos de arma en el sentido de un movimiento giratorio de cada eje de tubo a lo largo de una superficie cónica alrededor de un eje vertical y/o de un movimiento giratorio a lo largo de un plano axial mediante este eje vertical. Maximum range of the mortar/ammunition. When firing at maximum loads, the reaction force of the shot is partially absorbed by the damper, with the remainder of these forces directly affecting the vehicle Document EP 0906553 A1 refers to a high-angle firearm, in particular a grenade launcher, and describes a curved shooting barrel comprising at least one pivoting adjustable gun tube, an adjustment mechanism for regulating the tube and an orientation device for the adjustment mechanism to direct the gun tubes in order to ensure a wide orientation field with easy handling. The orientation device has an independent orientation apparatus, preferably arranged separately from the adjustment mechanism, by means of which it is possible to activate the adjustment mechanism for the lateral and height orientation of the gun tubes in the direction of a rotary movement of each tube axis along a conical surface about a vertical axis and/or a rotary movement along an axial plane through this vertical axis.

En el carro está montado el primer extremo de un brazo pivotante que puede girar en torno a un eje de giro, cuyo segundo extremo está conectado con una rótula que guía el cañón. La rótula está provista de una carcasa, abierta en sus extremos, en la que está montada esféricamente una parte interior, que contiene una guía cilindrica del cañón, para alojar de forma móvil el cañón.

El criterio principal del diseño del sistema portamorteros embarcado propuesto se basa en mantener las prestaciones operativas de arma simple y eficiente del mortero manual. El sistema puede ser instalado en cualquier tipo de vehículo 4 de carga ligera desplegando el arma (el mortero) al suelo 8 para su operación. De esta forma, la reacción del disparo es transmitida directamente al terreno (como un mortero convencional), sin necesidad de amortiguadores, y por lo tanto sin pérdida de capacidades como el alcance máximo o la cadencia de tiro, ambas afectadas por este tipo de dispositivos. The main design criterion of the proposed embarked mortar carrier system is based on maintaining the operational performance of a simple and efficient weapon of the manual mortar. The system can be installed in any type of light-load vehicle 4 by deploying the weapon (the mortar) to the ground 8 for operation. In this way, the reaction of the shot is transmitted directly to the ground (like a conventional mortar), without the need for shock absorbers, and therefore without loss of capabilities such as maximum range or rate of fire, both affected by this type of device. .
