The one with the internal detail is amazing. Can we persuade Rita to do a build thread on one of her models?

I certainly think she would make a valuable member here.

In all fairness to Rita,Richard,I think that she has a lot of involvement with the dolls house groups and would not be able to find the time,I took the photographs at her request as she needed to submit them to an American group that she will be giving a workshop to in the future.
But I could always take a few build pictures with her permission and ask her how she starts the models.
They really are quite unique and charming miniatures not looking out of place on a model railway layout.

Rolls Royce have come back with the followng,re how a jet engine works-
Yes, the RPM will change (fluctuate) within the engine as there are effectively 3 different rotating assemblies in a Trent Engine spinning at different speeds. You have the Bypass fan at the front which is connected via a long shaft to the rear set of turbine blades. This assembly rotates with the lowest rpm, then you have a Low Pressure Compressor which is connected via another shaft (each shaft runs inside the other) to the Low Pressure Turbine and this rotates at the mid rpm and lastly you have the High pressure Compressor which is connected by the shortest shaft to the high pressure turbine and this all rotates the fastest.
The idea is that you extract the energy out of the gas flow in the most efficient way in the Compression and turbine sections by using progressively smaller and faster turning blades which then maximises the engines thrust and fuel efficiency.
Simple really ;-)

So in answer to your question, the blades aren't all attached to one shaft as there are actually three seperate shafts (Fan , LP and HP) inside a Trent engine and they all rotate at
different RPM's!
Hope that helps.

Now that makes more sense. I never realised there were three seperately rotating turbines.

Thanks for the clarification Barry, who says you can't teach an old dog something!!

We all learn something everyday via each other,that is the fun and practicality of this forum,John once said to me that web sites are great but a forum even better because they are a living thing.
And once more I have always found that even professionals are ready to share information with us all.

Today my plastic and I were "taken" xmas shopping (with token kicking and screaming) ,Tk max are selling a very strange mix in the toy bit, car kits ,slot cars ,scaletrix and assorted others cheap if it's of interest to anyone.

Todays guest modeller is non other that Rita's husband Roy,he just happens to be a small scale model builder of some experience,whilst shooting the miniature dolls house's I also photographed Roy's models as well,another of his interests is full sized ballooning and he once owned the former 'Bizzie Bodies' balloon G-BUSY,and also the HP.60 powered model airship G-ERMS,Rita also is heavily involved with ballooning record flights being an official adjudicator and travels worlwide to such events.
Anyway here are a few of his current models mostly esoteric subjects of great interest.

Hey Barry, ask Roy about the tailplane on the Ludd. I didnt find it on the free plan. Did he just gessimate it or was it published later ? Anymore info on the airship G-ERMS ? Is that an out of sequence special registration ? Must have been big to need a .60.

wonwinglo

Duncan,the Ludd presented a lot of problems for Roy,parts missing,parts that did not fit,the usual things that happen with free plans that are drawn after the model has been built instead of the other way round,I will ask him how he got around the missing parts problem for you.
Regardng G-ERMS this is a unique one off Thunder AS-33 Hot Air Airship built for reasons unknown in 1978,named 'Microbe' she has been on loan since 1993 to the British Ballon Museum,sadly the gondola has got lost and Roy is in the process of researching the dimensions to build another,it had forward propulsion via the HB61.
I saw the envelope last week all packed in a large bag,it was last inflated I believe at Wellesbourne airfield on the occasion of a fly-in there,there were a few controlled airships built around that time one being built by Portslade school,Roy is keen to preserve this example,if anyone can elaborate on its history and real purpose then he would be delighted to hear from them,you can relay any messages via the forum.
Model balloons need to be registered with the Civil Aviation Authorities,and must not carry fire under any circumstances,in recent years examples have been inflated at the balloon festival held at Bath.
