The present Marter’s thesis aims at analyzing the contributions of an informal task-group that existed at the Pontifica universidade Católica do Rio de Janeiro (PUC_RJ), from 1971 to 1974, with elements belonging to the departament of mechanical Engineering and to the institutos tecnologogicos (ITUC) of that University, synthetlinzing the conceptual developments and the satrategies of organization and action whitch were used by the group. This group, adopting a socio-technical methodology of conceptualization and action, proposed to give a systematic and short-range contribution to the growth of the techonological potencial for experimental activities in The thermosciencies at PUC-RJ, aiming at putting a hypotheses it defend into pratice. This hypothesis was that the growth of the capability for experimental research would constitue a key strategy and graduate programs, in terms of predominantely indigenous guidelines and resources, and it derived from the fact that the group belived that an axperimental program: (1) would necessarily be based on an irrplaceable and non-transferable infrastruture, which would be transmissible infrastructure, which would force indigenous development; (2) would lead to permanent results, wich would be transmissible from generation to geration of new research professors, favoring, therefore a step-by-step and irreversible growth of the reserch and graduate programs; (3) despite requiring a more complex and long-range organizational challenge than that associated with the development of theoretical researches (since theorical development builds on experimental data and validation); (4) would favor the establisment of healthy links between the academic and indstrial sectors, by supplying industry with enegineers and scientists having expertise in university-based experimental research. This, itself, due to the performace of such professionals in the natinal produtive sector would allow the materialization of the growth of research programs with an academic basis, by means of a progressively more adequate University industry context. One can extract from this Thesis a set of reflections, projects and experiences which are uniquely appopriate to the continuation of the growth of the Experimental Program in the Thermosciences at PUC-RJ, as well as, in our confident opinion, subsidies for a national strategy for revitalizing graduate reserch programs in engineerring.
