10 secs to impact!!!

Are you talking about the weight of the various transport sections (see diagram)?

I’ve had a quick look in ‘The Lancaster Manual’ but I couldn’t find these weights listed anywhere.

Creaking Door, thank you. That’s a section of AP 2062 that I have not seen before. To have the weights of most of the items shown would certainly solve my problem.

I need to calculate the moments of inertia of at least the major components about the CG. An explanation is given in the attached file ‘Explanation for critic.doc’. I have also attached four jpg images to show my work.

When complete, in another six months at least, the Lancaster will be offered gratis with a strong suggestion that a donation to one of the RAF, RCAF, RAAF, RNZAF charities is appropriate.

I would welcome any suggestions or criticisms.
Many thanks
Mike

To have the weights of most of the items shown would certainly solve my problem.

I’m surprised that the weights of these sections aren’t in ‘The Lancaster Manual’ (unless I’ve missed them).

I’m sure this information must be recorded somewhere…..does anybody know where? :confused:

Great work by the way!

Somewhere here I have the weight distribution manual for FM 219, have to find er, DB

bolyman, that would be great (much, much more than great!). But remember it is structural component weights that I need: wing sections, tailplanes, fins, fuselage sections, wheels etc.

PA474 will have a loading sheet in the 700….there will also be a preparation for weigh statement in the AP too (drain to unuseable fluids (ohh err!)). Modification lists give mass and balance data too.

I will have a think about possible other sources too…..Fluffy will no doubt have more knowledge on this, especially since they need to hoist items at the BBMF etc. With the impending show season etc he may be too busy though

I’m of an era long after Lancaster went out of service but if the AP system worked in the same way as that post-war, then I would be looking for the answer in the Vol 6. If I recall from many years ago, the Vol 1 was leading particulars (and generalisations – my words), Vol 2 was Mods, Vol 3 was the Spares Schedule (list of bits – my words), Vol 4 – not sure, think it was something to do with test schedules or was it Routine Maintenance schedules (?), Vol 5 was handling notes, safety warnings and so on. Vol 6 (I’m fairly sure) was the Repair Manual.
As I say, it’s been a long time that I have seen the Vol 1 to 6 system and the memories are a little clouded these days.
Perhaps someone with the real breakdown of APs would be kind enough to come on and confirm or clarify my uncertainties. Has anyone got sight of a full suite of Shackleton APs to use as an example?

Thanks very much indeed, Mark

I am pretty sure the component weights for the similar sections of the Lincoln exist, I am sure I accessed them when planning the move of RF342, I will have a look in some manuals tomorrow if I can and report back.

While the Lincoln’s components are not exactly the same (longer centre fuselage, differing nose etc) the relative % should allow you to divvy up a Lancasters weight proportionally with some level of accuracy?

I suspect the B-24 component weights and dimensions should be readily available, they are for Consolidated’s older product the PBY in its manuals, I have no idea in regard to the Halifax, but I would have thought the RAF would have all of these weights/dimensions recorded in some wartime store manifest or Engineering Order for CRU’s etc?

(Interestingly, I have RAF Pocket Handbook 1937 -AP1081, which has a loose leaf appendix V, with the cased and uncased dimensions and weights for all the 1930’s pre war aircraft from the Audax through to the Whitley, as well as vehicles, firetenders and crash boats etc unfortunately the Lanc was but a twinkle in the eye in 1937 smiles)

Plan B

I’ve got to accept that it is now unlikely that the data I need still exists.

I believe it would be reasonably easy to calculate the volumes of the various structure components. Then if only I had a value of the individual structure density of these, I would have a reasonable approximation – I think?

Now if I assume that the individual structure component density across the major constructors of that time was more or less the same. I can apply those to the Lancaster to obtain an approximation to the individual weights – valid assumption?

So how do I get this information for aircraft like the B24 and the HP Halifax? Or has this gone with the wind as well?

Comments, criticism, help and brickbats – all gratefully received.
Mike

I got in touch with Fluffy – many thanks, Paul. But no joy.

I’ve just received a note from Harry Holmes, chairman of the Avro Heritage Group. He says:
“I am sure that the answer lies in A.P.2062 Vol II. which covers the repair schemes including the break-down of sections with weights, etc. I afraid the I do not have one and despite all the stuff I do have there is nothing that meets your requirements and this includes the material in the Avro Heritage Centre at Woodford. Now, if you had asked the same question about a Vulcan then we could have given you the answer!
Sorry about that, but if you do eventually find the answer please let us know.”

Does anyone have or access to a copy of AP 2062 Vol II that Harry mentions?
Even if some one could just confirm that the Lanc component weights are there in that volume, that would be a big advance.

Best wishes
Mike
