Navy Eyes Unmanned Vehicles for Dangerous Missions
Textron Land and Marine System has successfully demonstrated its Custom Unmanned Surface Vessel, which it aims to sell to the US Navy to perform risky missions like minesweeping and approaching enemy sea vessels. (Source: Textron)
Not only the technology of being un-manned-(remarkable enough); but another technology (not described in much detail): An anti-sinking feature that enables the boat to automatically shut off, right itself, and resume its course if it capsizes. That is amazing!How about commercializing that feature into mainstream yachting-?Bet the captain of the Costa Concordia (the sunken Italian cruise ship) would have liked that feature?!
Beth, that is a good question. Considering mine sweeping, approach to hostile ships, etc. this seems like a natural for this type of technology. It also seems like it would be easier, since you are constrained in one dimension. There may be other issues, or it may just be that the need has not been percieved.
Seems like a natural move to beef up technology to support unmanned sea vehicles for risky missions just like the Air Force uses UAVs. I'm curious why there hasn't been much real work in this area up until now. Are there more limitations?
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
