- Abstract
The bench test is a tool that provides important information about a given device. Each test is designed for some specific information and it should be able to hold certain physical and electronic features. Part of the process of developing rocketry in this project, requires specific information for simulation and design of solid rocket motors with the capacity to reach 20 km altitude. Test bench is designed to provide data necessary to determine the dynamic of the rocket candy solid fuel engine and the static characteristics. So that sufficient data are available for a better approach to model actual launch of a rocket. Given the physical requirements of the engine, test bench must be able to measure the force generated by the rocket from the time of ignition until the time it is turned off, so you can generate a graph of force generated by the engine against time. These data are important for calculating the distance lifting the rocket vertically and the force generated. In addition, the test bench for rocket engines must be able to generate a dynamic model with data engine speed from initial velocity equals cero up to a short distance (1m), this to determine data for takeoff, design shuttle and flight data engine variables. Additional testing engine solid rocket fuel, has a design for the inclusion of a turbine air BEE II Jet Central, which can replace the rocket engine during the test, so that it generates data from a controllable engine generating a database useful as a comparison between different environments, starting position, launch angle, fuel, control data, among others. To meet the requirements established, the test bench for rocket engines must be able to withstand the forces necessary to engines designed to reach heights of up to 20km, should also be able to make both static and dynamic analysis. It must provide the necessary security for personnel engine testing, and must contain the sensors and the electronics needed to obtain data required for this test. As the base design, a steel structure is planned, with a slider and a positioning mechanism able to fix position in a given angle for different starting conditions. It must contain an attachment to ground to prevent movement of the bench, and designed electronics should be able to withstand the temperature, the strength and the ability to capture the speed and the forces generated by the testing tool.
