It is widely recognized that simulation is pivotal to vehicle development, whether manned or unmanned. There are few dedicated choices, however, for those wishing to perform realistic, end-to-end simulations of unmanned ground vehicles (UGVs). The Virtual Autonomous Navigation Environment (VANE), under development by US Army Engineer Research and Development Center (ERDC), provides such capabil...

Abstract This paper presents experimental and numerical CFD studies of the aerodynamics a turbine rear structure (TRS). The TRS test geometry is an engine-realistic state-of-the-art design with polygonal outer case, recessed engine mount bumps, three different vane types: regular vanes, bump vanes in sectors, thick vanes. Using sector types simultaneously was found to be crucial for inlet bound...

The technical task of creating new designs submersible vane pumps is to maintain stable operating parameters and increase the productivity pumping station with periodic regeneration sediment removal. well contains an outer chamber inner chamber, in which a unit installed, pipelines are connected lower upper pools. In structure under study, parts chambers equipped sealed head, part stopper. side...

In order to study the influence of position bulb on hydraulic performance a submersible tubular pump device, based large-scale pumping station, two schemes—involving front-mounted and rear-mounted bulb, respectively—were designed. The scheme uses GL-2008-03 model its conventional guide vane, while optimized design diffuser vane. method combining numerical simulation experimental testing was use...
