Environment design criteria: boosting efficiency and minimizing risks and costs in launch vehicle development

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 →
