La eficacia de los sistemas de lanzadores m\u00faltiples (MLRS) en los campos de batalla actuales depende en gran medida de la confiabilidad de la operaci\u00f3n y, por lo tanto, del funcionamiento adecuado de todos los componentes, especialmente los cohetes y los propulsantes. Por lo tanto, las propiedades de los propulsantes s\u00f3lidos para cohetes utilizados en los motores de cohetes deben determinarse con una herramienta eficiente y confiable que proporcione resultados repetibles. El art\u00edculo presenta los resultados de un an\u00e1lisis termomec\u00e1nico de un propulsante s\u00f3lido doble base utilizado en MLRS. Uno de los m\u00e9todos recomendados para probar propulsantes s\u00f3lidos de cohetes es el an\u00e1lisis mec\u00e1nico din\u00e1mico. Propiedades mec\u00e1nicas como el m\u00f3dulo de almacenamiento din\u00e1mico (E’), el m\u00f3dulo de p\u00e9rdida din\u00e1mica (E”) y la tangente tan(\u03b4) del \u00e1ngulo de cambio de fase (E”\/E’) se midieron con el uso de un dispositivo para an\u00e1lisis mec\u00e1nico din\u00e1mico\u00a0 TA Instruments DMA Q 800, en un rango de temperatura de -100 a +100\u00a0 \u00b0C con el uso de diferentes frecuencias de fuerza aplicada y velocidades de calentamiento. Se prest\u00f3 especial atenci\u00f3n a la determinaci\u00f3n de la temperatura de transici\u00f3n v\u00edtrea seg\u00fan el acuerdo de estandarizaci\u00f3n STANAG 4540, as\u00ed como a la influencia de los par\u00e1metros de prueba en los resultados experimentales obtenidos. El an\u00e1lisis mec\u00e1nico din\u00e1mico ha demostrado ser un m\u00e9todo eficaz para la evaluaci\u00f3n de propiedades clave que influyen en el comportamiento de los motores de cohetes.<\/p>\n

The effectiveness of multi-barrel rocket systems on today\u2019s battlefields is strongly dependent on the reliability of operation and, hence, proper action of all components, especially rockets and propellants. Therefore, the properties of the solid rocket propellants used in the rocket motors must be determined with an efficient and reliable tool providing repeatable results. The article presents the results of a thermomechanical analysis of solid double-base rocket propellant used in multi-barrel rocket systems. One of the recommended methods for testing solid rocket propellants is dynamic mechanical analysis. Mechanical properties such as the dynamic storage modulus, the dynamic loss modulus,<\/span><\/span><\/span>\u00a0and the tangent tan of the phase shift angle were measured with the use of the TA Instruments DMA Q 800 device, in a temperature range of \u2212 100 to +<\/span><\/span><\/span>100\u00a0\u2218<\/span><\/span><\/span>\u00a0C with the use of different frequencies of applied force and heating rates. Special attention was devoted to determining the glass transition temperature following the STANAG 4540 standardization agreement, as well as the influence of testing parameters on the obtained experimental results. Dynamic mechanical analysis has proven to be an effective method for the evaluation of key properties influencing rocket motor behavior.<\/p>\n
