Hi folks, I've been around a bit in the forum, but not in this section. It may be a very good place to get some criticism. These pics are from my 3D CAD drawings at full scale derived from a clutch of badly corrupted photocopies of the original Avro drawings. I've tried to preserve the...

Drgondog, I'm delaying somewhat my analysis and reply to your excellent assistance. The support team of the simulator have published a collection of examples to illustrate the functioning of the simulator in regard to component joints and harmonic vibration. By trying to match the theory to the...

There is some repetition here. I apologise. But perhaps it is clearer and I need to set the scene for my problem which is told at the bottom. I believe that AFPD/Aerofly is a serious simulator with predictive ability. That is, it has enough physics and engineering theory built into the...

Ernst, you seem to be doing some very good stuff. I understand a little of the calculations shown in the page you reference. But I need to study a great deal more. My interest is the Avro Lancaster. I would like to see data for the Lanc similar to that of the P-51 you have presented. My...

For AFPD and the new Aerofly 5, each component has at least 124 data values; some of these being combined as vectors. My A10-TL2 model has 21 components. The two main issues determined by some of these data values are: the performance of joints between components and the inertial properties of...

Sorry for the delay in replying, Red Admiral. I’ve had the builders in with the consequent total paralysis. First, the simulator is a relatively sophisticated one; but it is aimed at the hobby market. It’s primary function is to teach radio control flying from scratch and to allow the planning...

Just a quick one. I'll reply at length in a couple of days or so. But in relation to tensor analysis, drgondog, do you recognise any of these parameters? From the new Aerofly 5 <[tmvector3d][InertiaLength][0.270850 0.956110 0.025000]> <[tmmatrix3d][Inertia][0.030492 0.000000 0.000000 0.000000...

Thank you very much indeed, drgondog, for an extensive and considered reply. I would dearly love to take a full course in aeronautical engineering; but at my age there just isn't time. I think my problem is somewhat more tractable. I'm not modelling reality at the level of sophistication and...

Apologies, the only way I know to talk about this is with maths. The objective is to create a reasonably accurate simulation model of my Avro Lancaster. Perhaps for obvious reasons, there is no documentation given with the simulator of these issues. Hence there is the need to create a good...

I'm building the best simulator model I can of the Lanc. I'm 8 months into what now looks to be a two year project. I'm retired now and can afford the time. My target simulators at present are two of the Aerofly technical simulators from Germany, particularly the new Aerofly 5. The model will be...

Thanks, Red Baron. I've just sent an email to them. But it's looking bad. I've tried many places without any luck. I suspect the data I need is lost now forever. Here is a reply from Harry Holmes, chairman of the Avro Heritage Group: "David Fildes of Avro Heritage passed on your email...

I've been advised to try this manual to find the structural component weight distribution for Lancasters' I/III/X. For simulation, I need to be able to calculate the inertias of individual major structure components such as fin&rudder, tailplane, fuselage sections, outer wing sections, engine...

Ee by gum,lad. I learn something new each day. Thank you. Mike

Seesul, I'm surprised nobody has mentioned the Lancaster. The Taboo system is a very good example of a mechanical device which guarantees the mid-upper gunner doesn't shoot off the tail of the aircraft. The system has two rollers, one for each gun, which travel round the track as the turret...

I need to have a weight distribution of the basic structure of the Lancaster. Can anyone help? Informed estimates would be a help. I need weights for: one wing including nacelles; but excluding Merlin engines de havilland or other propeller Main undercarriage excluding wheel Main wheel...
