“…This is the case of CLA, where strong winds are observed during the dry season, from July to December. The ABL and atmospheric from observations, numerical simulations, and wind tunnel measurements (Pires et al, 2008;Avelar et al, 2010;Fisch et al, 2010;Marciotto et al, 2012) The present work is an extended version of a paper recently presented at the fourth AIAA Atmospheric and Space Environments Conference, in New Orleans, from 25 to 28 June 2012, Avelar et al (2012), and it is also a continuation of a previous study (Avelar et al, 2010), in which the procedures for a boundary layer simulation in a short-test section wind tunnel (TA-2) were described and some preliminary results CLA region, were presented.…”

Centro de Lançamento de Alcântara is the main Brazilian launching center. In spite of presenting several desirable aspects, due to its proximity to the Equator, it has a peculiar topography because of the existence of a coastal cliff, hich modi es the characteristics of the atmospheric boundary layer. his may affect roc et launching operations, especially hen associated ith safety procedures. his or is a continuation of previous experimental studies about the air o pattern at this launching center. An improved ay of simulating the atmospheric boundary layer in a short test section ind tunnel using passive methods is presented here. It is also presented a preliminary analysis of the air o pattern in Centro de Lançamento de Alcântara, at speci c positions as the edge of cliff and around the mobile integration to er, from ind tunnel measurements using particle image velocimetry. hree values of eynolds number, based on the coastal cliff height, l, ranging from 6.8×105 to 2.0×106, were considered.

The atmosphere is the layer of gases that surrounds the planet. The atmosphere is retained by the gravity of the planet. Hence, it is also called planetary atmosphere. The performance of the aircraft and rockets depends on the physical properties of the atmosphere in which they fly. It is therefore advisable to study the variation of pressure, temperature, and density with the altitude. The real atmosphere is composed of dust, water vapor, and moisture, and it never remains constant. Hence, a hypothetical model called a standard atmosphere was employed. This chapter elaborates the international standard atmosphere, atmospheric boundary layer, and the stability of the atmosphere.
