Obviously brought about by the thawing of relations with Iran……

A lot of complaints are aimed at the RAFM for the ‘son et lumiere’ part of the Battle of Britain hall. I agree it can be a bit annoying or you could take a seat and watch it! There can’t be anyone on this forum that doesn’t know it takes place so why not, when you arrive, take note/find out what the running times are and visit that part of the Museum accordingly?

It does seem strange that the ‘carrier deck’ show at the FAAMuseum doesn’t attract similar critiscm.

Don’t get me wrong there are things about the RAFM and it’s actions I don’t like but, I think, almost anything is an improvement over when it first opened to the public. Visiting not long after it opened, whilst it was wonderful to see all these aeroplanes on public display at last, my first impression of the place was a cross between a cathedral and a hospital!

Sound idea, and good to have you back Kev.

Buuuut “in theory” can’t the Design Authority be transferred eg at the other end of the spectrum DHSupport?

Trying to remember back nearly 50 years to my apprenticeship at Dunlop in Coventry……

I think there were three types of rubber ‘boots’.

Those that were rigid and were supplied hot air (from the exhausts?) the heated rubber preventing ice forming (anti-icing)
Those that liquid de-icer fluid was sent under hydraulic pressure through the boot to exude out of small holes and prevent ice forming (anti-icing)
Those that were flexible pneumatic boots where pressurized air was sent in to stretch the rubber and expand it so after the ice formed the expanding rubber would cause the ice break off (de-icing)

However in my days there the latest weren’t exactly boots but rubber strips that had electrical elements running through them which would heat up (anti-icing). These rubber strips would be bonded to the skin of the aircraft and this meant the parts of the aircraft so equipped would be shipped to the Coventry factory and the bonding was carried out in large ovens. There was a lot of Fokker F.27 bits around then, as well as flying surface leading edge units the rubber strips would be all around the engine intakes.

Towards the end of my time there were new l-a-r-g-e ovens being installed for what appeared to be a growing market for anti-icing units for helicopter blades – I think the whole blade went into the oven.

So, ‘rule of thumb’ anti-icing prevents the ice from forming in the first place, de-icing gets rid of the ice once it has formed.

What I’d like to know is if the calculations using horsepower takes into account the thrust from the horse when it lifts it’s tail and f*rts?
