The present paper considers utilization of rocket motor propellant grains that consist of two propellants. The idea is to achieve approximately neutral burning using an outer surface inhibited cylindrical shape and complex contact surface between propellants. An existing propellant grain with complex geometry has been analytically modeled in terms of determination of evolution of corresponding burning surface areas. The analytical and experimental results? diagrams of this grain have been found to have a saw-tooth shape because of the segments that separate the two propellants, causing potential problems in the burning process during the relatively short active phase, showing an obvious need for further optimization. This has created an opportunity for development of improved propellant grain geometry and corresponding mathematical model for determination of main interior ballistic parameters. Comparison between calculation results based on both models and experimentally determined chamber pressure data shows very good agreement. Therefore, two-component propellant grains have significant application possibilities using the suggested modeling approaches.

To qualify the design of aerospace structures, which are designed with minimum margin, it is necessary to subject them to static structural tests to reveal the real state of stress on flight structures under critical flight load conditions. This process build up confidence in the design methodology adopted and to validate the mathematical model used for simulations. In any space mission, safety holds utmost priority. Structural qualification tests are necessary to verify structural adequacy and to qualify the design. The primary objective of a structural qualification test is to assess the exact real performance of a structure and to validate its design. Static structural testing is a common method for verifying or ensuring that the realised structure has enough strength to withstand the loads for which it is designed. This study focus on the configuration and design of base platform. The base platform is intended to provide anchoring to the entire test rig assembly or to act as a foundation for distributing the moment and force reactions acting upon it. At present anchoring plates which are embedded in concrete strong floor is provided for mounting the test rigs. This set up requires reinforcement of the floor to certain depth and attracts major civil works. The proposed platform, which is a reinforced platform with gridded construction, is a replacement for the present set-up. Here we adopt the concept of modularity in configuration of the base platform. Hence the base platform is claimed as a modular gridded base platform with all the inherent features of modularity such as scalability, interchangeability and reconfigurability. In addition to the generation of a realisable configuration, this study expanse with the design of structural element and verification by Finite Element Method using Abaqus.
