The influence of the Natural Environment is a factor that affects all phases of launch vehicle/aircraft design, development and operation. Factors such as wind, turbulence, temperature extremes, atmospheric density, ionizing radiation, meteors, space debris, plasma and events related to solar activity, among other environmental phenomena, represent constraints and specific requirements that must be taken into account from the beginning of the project development program for a launch vehicle, so that it presents maximum efficiency in fulfilling its mission. The application of environmental design criteria aims to minimize risks, reduce costs and obtain the best possible vehicle performance. … Read More →

Study characterizes the precipitation events that can occur during the dry quarter in the region of the Alcantara Launch Center. Data collected over 37 years was used to confirm their average features and obtain the large-scale organization of the convective activity during higher precipitation events. The results presented could be helpful for short-term weather forecasting during launching missions. … Read More →

The present article details an experiment using a scale model of the Launching Pad Area in a subsonic wind tunnel, using the particle image velocimetry (PIV) technique to collect results in different wind flow incidence configurations. The results identify the peculiarities of the region’s typical wind action, and its effects on launch structures and operations on one of the world’s most strategically located space launching bases. … Read More →
