Shipbucket

Something completely different, a low-cost Littoral corvette designed by one of our researchers (Nick Bradbeer) as a familiarisation exercise with the design software and method.

Single shaft to reduce costs, an upperdeck mission bay capable of supporting up to two CB-90s, or more practically, a range of UXVs and containerised systems. Guns of 76mm and 155mm were possible (but with a reduced magazine capacity for the latter).

CB90 / 76mm version shown here.

very interesting. I have to say, I am kind of interested what kind of work exactly you do, as I am an shipbuilding student myself and want to specialise in naval shipbuilding.......

Interesting design. Somehow it feels top heavy to me......

Interesting. CODAD or CODAG?

Also, what's the sensor fit?

I'd use the latest version of RAM, and I might use a different screw but those are minor things.

whats the thingamgigger on top?Also the French and Isereali navies have proven you don't need big guns for adequate NSFS

This is an extremely ambitious design for such small tonnage, but it makes sense if it's strictly an exercise.

The exhaust outlets look cool

Hi All,

Minor changes to the image in the OP - trying to come up with a new propeller. Not entirely happy with it...

Anyways, propulsion is CODLAD. "L3" means "Low Speed, Low Cost, Littoral". The electric propulsion is to give greater flexibility at slow speed, although with relatively small steps between the power of the installed engines, a direct-drive option would probably be possible. The diesels low down and use of composite masts (note the panels on the foremast for the radars inside) helped achieve stability.

Macks were used to save space. Although they are unpopular with the electronics designers, the low power of the installed diesels should make them practical here.

The interest in the 155mm was due to the guided ammunition natures (copperhead). As a design group we have a liking for our deployed (un)manned vehicles to be able to call upon precision fire support (ask yourself this; what is the most heavily armed helicopter deployed by the British Army?). This design dates from 2008, so we'd probably use the Italian 127mm with Vulcano nowadays (and the same designer did just that on another project, to be seen later).

Deep displacement was 2500 tonnes. Personnaly, I think it would end up around 3000te once the design was developed. It only seems ambitious here because of the CB-90, which was the extreme option. With the more practical outfit of, say, 3 Spartan USV and supporting containers it would be much more reasonable.

Sensor fit included: 3D search radar in the "bulb" on the foremast, RTN-10X FCR over the bridge, ESM, Single SCOTT and the usual communications systems. The sonar is a small minehunting set as on the LCS. There was also provision for RECM Type 675 and CESM COBLU.

As to what I do;

I'm the senior researcher in the Design Research Centre in the Department of Mechanical Engineering at UCL.

http://www.mecheng.ucl.ac.uk/research/m ... -research/

We work closely with the NAME researchers:

http://www.meng.ucl.ac.uk/~nag_web/

I'm sustained by research funding, typically 3-year projects from the EC or UK bodies such as EPSRC and most recently ONR-Global. These are on subjects ranging from fire safety of passenger ships to low carbon shipping. My personal research interest is in the development of computer aided ship design methods - my PhD was in this area - particularly those employing new interface methods. Within this, I also carry out unsolicited design projects to support more general research aims (e.g. an electrically armed Type-45 replacement, a UXV carrying submarine etc) and consultancy work (e.g. OPVs for NDP, JSS for one of the bid teams, LCS for ONR Global, Motherships with BMT for MoD).

This is pretty typical of a post-doctoral researcher, with ones time split between several projects. At doctoral level (in the UK anyway) one would expect to be focussed on a single subject. All the DRC PhD students (3 working, 1 completing, 2 to start this year) are on industry-cofunded research within specfic interests (e.g. survivability, upperdeck EMC etc). My PhD was a little different in that I had no single funding source, so essentially was told to do some designs, then write a PhD about it!.
