The integration of uninhabited aerial vehicles (UAVs) into controlled airspace has generated a new era of autonomous technologies and challenges. Autonomous aerial refueling would enable UAVs to travel further distances and loiter for extended periods over time-critical targets. The NASA Dryden Flight Research Center recently has completed a flight research project directed at developing a dynamic hose and drogue system model to support the development of an automated aerial refueling system. A systematic dynamic model of the hose and drogue system would include the effects of various influences on the system, such as flight condition, hose and drogue type, tanker type and weight, receiver type, and tanker and receiver maneuvering. Using two NASA F/A-18 aircraft and a conventional hose and drogue aerial refueling store from the Navy, NASA has obtained flight research data that document the response of the hose and drogue system to these effects. Preliminary results, salient trends, and important lessons are presented.

El presente proyecto de investigación surgió como expresión de una inquietud promovida por la carencia de estudios sistemáticos que aborden la sociedad argentina alrededor de los años '20. Si bien desde la década del '60 se han producido avances en lo relativo al período 1916-1930—tanto en el campo de la Historia como desde la perspectiva de otras ciencias sociales— resulta evidente que resta mucho por hacer.
