Deltic engine origins surprised me

What is the story behind the banana on the bridge?

Its HMS Brinton it turns out: http://tca2000.co.uk/?page_id=1035 Beyond that no idea!

I served in Brinton in the late 80's early 90's...All the Ton class sweepers had a bridge screen ornament of some description...Kellington had a large Kellogs "K"....I think the Nurton has a large Duracell battery...one of the boats had a Gollywog etc etc....back in the days when the MOD still had a sense of humour.

So was there a particular reason/background to the choice of a banana?

It had an association with Fyffes bananas when it was stationed in the West Indies.

Deltics as well as other diesel engines were tested for the Navy at the former National Gas Turbine Establishment at Pyestock, between Farnborogh and Fleet in Hampshire. I did part of my apprenticeship there, and was shown the Deltic and had its workings explained to me, although I don't recall actually working on it. The focus of my attention for three months was the Paxman Valenta (2250hp, V12, 79 litres), and struggling to get the massive pistons and conrods out after extended running to determine wear and carbon build up.

The Valenta. As used to be fitted in HST power cars. They were LOUD!

The Deltic was also used in RN Minewarfare Counter Measures
Vessels. Dont think it was very reliable.

A friend in the States fought in Vietnam on Nasty class fast patrol boats. They had two blown Deltics. He never mentions poor reliability in particular. He manned one of the .50 cal guns.

Seems like they were all destroyed after the war. Some interesting engine stuff and links here

Well, a few years ago there was a team restoring one, so perhaps one escaped?

Just seen this- Fairbanks Morse opposed piston engines

https://oldmachinepress.com/2019/08/20/fairbanks-m...

similar idea to a Deltic, with shared ancestry (Junkers). This time in a Diamond formation, intended for use in ships and submarines

The USN's two rigid airships had a condensing system to recover water from the exhaust gas, so water ballast could be taken on board at the rate of roughly 3/4-lb water for every lb of fuel (petrol) burnt.

I like that! Hadnt thought about the issue of fuel-ballast on airships till now.

If there was one picture to epitomise BR in the 70's, this is it.

Cracking that isnt it!

Opposed piston engines are still being developed. ...


and BWM a RIB (Rigid Inflatable Boat) manufacturer, have one for their boats:

Sums up the first few years of my railway career, looking across the cab through a haze of smoke from a Woodbine(his not mine) .. Teamug blanced on the desk and a discussion about where we could get a pint! Sadly closest I came to a Deltic was at my first depots open days(Coalville for those interested). Back to Deltics, a well know millionaire from Huddesfield owned one of the preserved Deltics and a rumour I heard hinted that a spare engine came from the New York fire department , nice if true. I pity the poor secondman when working in steam heat as the boiler is situated in the centre , no ear defenders then.

Same as us with the 'Westerns" stuck between two screaming Maybach's wresting with the boiler, and they wonder why so many of us are hard of hearing with tinnitus these days?

Would have been a fire department super pump, stumbled across a video of one today. https://youtu.be/0mA3cP2UhiU

This turned up at work a few weeks back, amazing bit of reversing by the hgv driver, got it along about 200m of road then round the corner into the loading bay in one go

They are such huge powerful machines they scare me doing nothing!

Absolutely beasts aren't they. Beautifully solid.

The Bristol Hercules radial engine looked like a mixed box of 20 sets of SpyroGraph !

Love this shot of the guy working on the gear drive assembly of a Deltic......pukka engineering

That looks like a “phase” case.

Imagine having to torque down all those studs

I used to; now imagine working on the when built... bloody awkward things
