Historic Whittle Engine Runs Again After 63 Years.

Excellent stuff! 😎 😎 😎

Aha! I saw you chaps on Look North while I was on holiday – you looked well-chuffed, and I don’t blame you either!

What a wondrous thing – thanks for sharing it with us!

Interestin…. i did a quick google for ‘262 in martham’ and found this…

Quite an intriguing list of aircraft…

Great vid on the BBC… excellent stuff…!
Robin’s face is a picture when he realises its lit up!:D

Now way I was gunna miss THIS!:eek: 😮 😮

A TOP thread:dev2:

I reckon Mr Whit, (RIP) would be very proud of such an amazing feat!!!:cool:

Now how’s that rich Yanky dude going with his want to run almost original Jumo’s I wonder:confused: :confused:

Now his 262 is an original 262 being Re-built I think:eek:

Oh to have that sort of MONEY!!:rolleyes:

The lucky lucky lucky B@stard 😀 😀 😀

Thanks for the comments mate!
Do you mean Paul Allens `262 being rebuilt at Martham?

Here is a link to the Welland running on BBC:

I should emphasis that getting this engine running order is very much a team effort involving Peter Grieves and Robin Byers here in Carlisle and Eric Barnes in Dorset.

I am sure it was a team effort and well done all.:)

An important contribution was made by household goods retailer Dunelm who sold me a stainless steel measuring bowl which was used as the basis for the fabrication of a missing combustion chamber dome.

Would that be the on the chamber at 6 o’clock?

Great stuff! Hope you stood well back when you started it…

Would it be an idea to post the next running on Utube? Then we could all hear it too.

A Jumo wouldn’t be worth running, as they had such a short running life. Check Eric Brown’s memoirs of flying captured German jets.

I couldnt help noticing in picture 4 what appears to be a starting handle on the floor of the rear of the trailer, and a starting dog to put it in…. 😮

Please tell me its got electric start….

i wouldnt fancy winding it up each time to start:o

There is indeed a starting handle I use it to get the engine turning before engaging the starter, on 12 volts, in order to take some of the stress off the pawls associated with the stating mechanism in the gear case. Once the electric starter has got the engine up to about 750 rpm on 12 volts I switch over to 24 volts. the engine then run up to about 1500 rpm when the accumalator in the fuel line trips allowing an energetic squirt of fuel into the combustion chambers when ignition occurs and we are off.

On health and safety, we do carry insurance and we do carry out risk assessments based on procedures made available by the Health and Safety Executive. It is quite possible that the biggest risk people take in attending air shows in driving there in their cars.

If it was up to the Health and safety people, we wouldn’t have airshows either! With the crash this week of a Blue Angel F-18, the media is beating their drum about “how safe is it!” and Should these things be allowed to continue!”

I guess next we will have to ban driving to work!! That is indeed dangerous!

Don’t want to a dark cloud on this, but what do the insurance companies and the health and safety people say about running engines such as the Welland?

WF

The thought had crossed my mind but like you I didn’t want to poor cold water on the party. I would imagine that the HSE would have much to say about public displays of engines such as this. When I think of what happened to some Avon engined Hunters (turbines coming adrift and sawing their way out) precautions are sure to be required.

Lovely work guy’s! A must see 🙂

I think most Rolls-Royce Welland’s did average about 160 hours or more between overhaul. When is it going on ebay?! (joke) 😀

WOW!!! Congrats on saving and getting her running!

How many hours could those old beasts run between overhauls? I know the Me 262 engine was very bad with only 10-25 hours on the clock before rebuild.

I would imagine finding parts is not the easiest thing to do. Wouldn’t want to run her too much or too long but to hear one run….WHAT A TREAT!

The max rpm for this engine is 17,000!
Pete

Centrifugal compressor turbojets normally have a higher max rpm than axial types with the outer part of the impeller reaching sonic speed – this being the cause of the high pitched scream of early jets.

I recall an adventure with a Nene. During 1965 Yeovilton air-station was developing a snow-blower by placing a redundant Nene engine laterally across the rear axle of a Bedford 3-ton truck. Old 50-gal drums had been arranged in a group of eight in two tiers of four behind the cab as fuel tanks. It was intended to place a 2-ton slab of steel across the rear axle under the engine to prevent tipping over.

I found myself on Crash-and-Smash (aka crash and salvage) for a period and between call outs (frequent – many other ‘interesting’ experiences being had) we worked on this snow-blow rig. Having waited for Belfast to cough up the steel slab for a month or so with nothing forthcoming and the year advancing it was decided to carry out tentative trials just to test the basics. The rig was arranged along Number 6 Hangar doors with the engine intake facing and close to the doors.

Things were working fine until the ‘tiff in the cab decided to find out what max rpm could be reached. As rpm was increased the intake side suspension noticeably compressed as the opposite side expanded at about 11-12000 rpm without warning there was a sudden lurch and the whole rig tipped into the door. Fortunately the chap in the cab was quick enough on the throttle to prevent a serious incident but his face had turned a whiter shade of pale.

ISTR the dent in the hangar door being there for years afterwards, if it is still there and puzzles some then here is the answer.

As for max rpm. I recall that the Plessey Solent gas-turbine starter for a UK Phantom rotated at a max of about 72000 rpm and produced over 90shp IIRC.

It is good to see this happening, well done Terry and all. 🙂

Great work – I greatly look forward to seeing (or more correctly hearing) somewhere this year.

How about in Coventry on June 1st to celebrate Whittle’s 100th birthday??

I take it this is the only runnable engine of this type?

Cranfield University restored and ran an even earlier Power Jets unit (a W2/700 I think) at Cranfield about 8 years ago.

New cook…

The newest attraction to Cockpitfest and Legends Airshow this year.The insta BBq.Will roast your snag in a flash….:diablo:
Congratulations and wow.Would this be the oldest running jet engine around?Would anyone be game enough to get a Jumo going as well???:D

Hi Pete, what took so long 😀

Well done gentlemen, a good job well done..
