We present a conceptual active optics architecture for a 16-meter aperture, deployed-optics Advanced Technology Large Aperture Space Telescope, to be launched by the Ares V Heavy Lift Vehicle, expected in the 2020 time frame. The ATLAS-T16 will utilize lightweight, deformable primary mirror segments. Wavefront Sensing and Control will be used to establish excellent optical quality following lau...

nowadays, the use of small vehicles is spreading among urban areas and one sort of these vehicles are three-wheeled vehicles (twvs) which can be competitive with four-wheeled urban vehicles (fwvs) in aspects such as smallness, simple manufacturing, and low tire rolling resistance, fuel consumption and so on. the most critical instability associated with twvs is the roll over. in this paper a ti...

Future reusable launch vehicles must be designed to fly a wide spectrum of missions and survive numerous types of failures. The X-33 Reusable Launch Vehicle Technology Demonstrator is used as a simulation platform for testing a neural network-...

Predicting and mitigating acoustic levels become critical because of the harsh environment during space vehicle lift-off. This paper aimed to study aero-acoustic a rocket The sound propagation within launch event was studied using dedicated computational fluid dynamics (CFD). resolution all phenomena that occur is unfeasible. We discuss turbulence simplification propose feasible simulation thro...
