New location for the ex-Flambards Gannet???;)

The mentions of degradation due to UV light (this can apply indoors as well as outdoors) reminds me of the suggestion I was told many years ago that “blacking” the tyres with appropriate paint helped shield the rubber from light and thus delayed degradation.

Roger Smith.

Might have been better stated as UV and other factors; wide temperature variations; freezing of the rubber; degradation due to oil or solvent contact etc.

Black paint may help I don’t profess to fully understand the chemical reactions involved – I just know that the preparation of all types of rubber compounds is a very precise and complex process, involving important chemical reactions that smell awful!

Yes it can be costly, but tyre-filling can also be more cost-effective than designing the axles stands needed to support something like a Vulcan!

Don’t intend to get into major debate on the topic but having made a call to someone at Newark this morning I would add the following:

Newark’s original decision re-high pressure tyres was coloured by former Restoration Co-ordinators experience on Vulcans where he saw tyres “go-off” – hence it was assessed to be a potential Health & safety issue and action was taken.

Flat spots can be an issue – understand Newark had an issue with Sea Vixen; partial cure issues with one batch of material.

The system is also beneficial through tubing and filling, where the carcass has degraded beyond normal repair and replacements are not available. Supply and technical support of old-UK based rubber products including tyres, brake-bags etc is becoming an issue.

The company Newark has used is Vacu-Lug and one of their sectors is the mining industry; filling vehicle tyres that are used underground and have to comply with Mine Safety Regulations.

As far as tyre carcasses and degradation goes – I have some experience in the supply of equipment to the rubber compounding industries [nationally and internationally]; as such I understand some of the chemistry involved. My instinct for tyres that are on aircraft outside and subject to high-levels of UV would be to fill them – better safe than sorry!

Thanks Roger!;)

I have posted before on this potentially controversial topic – but I understand that all of Newark’s high pressure tyres [Vulcan, Lightning, Sea Vixen etc] are filled; done by a company in Grantham I believe.

As far as BAPC goes check ….

Seems a shame to see that AOP9 sat out in the rain!!!!

Lots of Austers out there to go into museum’s one day!;)

The Perciavl aircraft at Lasham is ‘Sea Prince C.1 WF137’ not a Pembroke.

Spot on David – a typo on my part I will amend the previous post!:o

Sadly it is not listed in edition 2 of the National Aviation Heritage Register [NAHR]; whereas the Sea Prince C.1 WF137 at Lasham is listed as Noteworthy, the same status as the recently re-located G-AMLZ.

Will it be in edition 3 of the NAHR when published?

I doubt it!

Part of this imbalance may be rectified later this year as I understand that in early June the Shackleton Association will be unveiling a new memorial for Coastal Command aircrews at the National Arboretum in Staffordshire.

No further details I’m afraid despite a quick Google search.

As for the Manchester area don’t forget that some Shackleton build was undertaken at the Chadderton factory – but not sure of the city / county border.
