A Sampson radar being lowered to a scaffold covered mast - looks to have a similarity to Duncan's (D37) mast.


Compare the two photographs; I still contend that this is Duncan (D37) - she is the only type 45 with these appendages!!

Sampson being lowered for installation on the foremast.

Sampson installed on the foremast - scaffolding in process of removal


.... and right on que she hove into view to confirm those appendages ;) :)

'HMS Daring' Foremast Delivered

01 May 2006

The HMS Daring foremast is loaded onto a barge at VT Shipbuildings Portsmouth facility. The HMS Daring foremast is loaded onto a barge at VT Shipbuildings Portsmouth facility.

VT Shipbuilding has completed its construction work on the Royal Navy's first of class Type 45 destroyer HMS Daring with delivery of the foremast to BAE Systems Naval Ships in Glasgow.

The 89 ton steel structure was lifted onto a barge at VT's Portsmouth Shipbuilding Facility and towed over 600 nautical miles by tug, completing the transit in just over four days.

The foremast was then transferred directly to HMS Daring, where fitting out will be completed. The major element of the foremast is to house the Sampson multi-function radar suite, which will be linked to the ship's Principal Anti-Air Missile System (PAAMS).

VT has already installed some 12,000m of cable inside the 19m high mast, with 800 different cables and 400 pipes included in the structure.

VT's Type 45 project director John Richardson said, 'Because of the crucial nature of the structure in relation to the ship's operational capability, it has been built to extremely tight tolerances to minimise radar cross section.

Inside the mast there is a highly sophisticated network of cables which has involved a demanding outfit integration task.'

This is the third foremast that VT has built for the Type 45 destroyer programme following previous structures delivered to BAE Systems'Maritime Support Integration Centre (MISC) at Portsdown Hill, near Portsmouth, and the test facility on the Isle of Wight where the Sampson radar is being developed.

VT Shipbuilding is building the bow sections, funnels and main masts of the six Daring Class ships so far ordered.

Blimey Harry are you on piece work rate now ;)

That was a labour of love by the look of it .

On the Isle of Wight; views of the Sampson radar test rigs/facilities

This post includes links from a Flickr photostream and is a departure from my normal practice of providing attachments derived from original images as seen on-line, supported with the source; appropriate accreditation; and/or attribution.

This course of action has been decided upon since I believe; that to include the selection of images that I intend to link would be a considerable departure from even the 'Fair Use' definition of the Copyright covering the work of the photostream owner.

---------------------------------

Ist link - showing the QEC mock-up in the foreground, behind which are two 'masts' for Sampson radar testing, partially obscured by scaffolding.

2nd link - showing a more complete view of the QEC mock-up, behind which are the two 'masts' for Sampson radar testing, again partially obscured by scaffolding.

3rd link showing the facility from another angle and partially obscured by the chain link fence. Note the masts for Sampson radar testing still have scaffolding around them and the left mast has is surmunted by a Sampson Type 1045 radar domed array.

4th link - showing the facility through a diamond shaped aperature of the chain link fence thus presenting a better image of the two masts for Sampson radar testing. As for 3rd link; masts still have scaffolding around them and the left mast has is surmunted by a Sampson/Type 1045 radar domed array.

_________________________________________________________


Attachment; showing the masts for Sampson radar testing - the mast on the right is shown complete with an example of Sampson/Type 1045 radar domed array.
Note:-
- that there is no scaffolding surrounding either mast.
- the metal platform (and access ladder) surrounding the mast on the right
- the radar dome is complete with four lightning conductors
- there is an appendage secured to and curved over the dome

Note:-
- the Type 45 mock-up foremast has a mast cap akin to Daring D32 (none of the other 5 ships in the class have this configuration);
- the Sampson/Type 1045 radar dome and mast cap have all eight lightning conductors (whiskers :) ) installed -
- (four on the dome - four on the mast cap).
- is that another Sampson/Type 1045 radar domed array bottom left in the photograph?

How am I going to test that?

Welcome to a new series of posts on the topic of test and certification. This post is by Graham Andrews, Analysis Commercial Manager at TRaC.

I’ve heard engineers say that the test and certification industry is dull, simply requiring the latest consumer item to be plugged into a standard test rig, but although there can be some repetition in the job, much of what we do is new, interesting and challenging.

A recent project involved testing the impressive Sampson Radar that BAE Systems Integrated System Technologies developed for HMS Dauntless, one of six new Type 45 destroyers which will provide the backbone of the UK’s naval air defences for the next three decades.

The radar is a striking feature on the ship, and weighing six tonnes and measuring seven metres tall, it went way beyond the typical run of the mill testing project!

Working with BAE, we split the testing into stages. Where we could remove subsections, we conducted conventional vibration testing at our Warwick and Wimborne laboratories.

We next suspended an electrodynamic shaker suspended from a crane at BAE Systems Integrated Systems Technologies on the Isle of Wight to drive the natural frequencies of the system. Our engineers had already conducted Finite Element Analysis (FEA) to prove the testing technique. This de-risked the methodology in advance of carrying out the study. The results compared well with the predictions extracted from the Nastran software package.

We then built a bespoke test fixture for the full Radar Array, a 3m by 3m two-dimensional structure. This allowed us to test the radar in its in-service configuration whilst transmitting vibrations from one of our LDS 964 electrodynamic shakers.

My Comment; by no means wholly Naval Radomes exclusive but a very interesting read.
