Abstract
mancal aerostático para uso como selo a fim de se executar uma vedação, um material poroso, que compreende um lado de duas superfícies opostas, é usado para restringir e distribuir de modo uniforme gás, líquido, vapor, etc. pressurizados externamente, entre duas superfícies, imprimindo uma força que é oposta às forças das diferenças de pressão ou molas que estão tentando unir as duas faces e pode assim criar um selo sem contato que é mais estável e confiável do que os selos hidrodinâmicos correntemente em uso.
