Whirlwind Figher Project Questions…

PS. I don’t suppose you have access to the drawings, do you?

Thank you so much, Anne! That really does help.

Just to be clear, then, blade DP54409 is specific to the 4/4 (uniquely Peregrine), and is not the ‘fatter outboard’ Mercury type?

I’ll be checking the DH archive for drawings. It won’t be a matter of finding (nonexistant) bits as far as the blades are concerned – we’re going to have to make new ones, methinks.

The knowledge was forced upon me!

Good luck with trying to find bits but I have the feeling you’re looking for a flock of chickens with nashers.

Thank you Anne, you certainly know about prop’s… May I ask how/why are you in possession of such detailed knowledge of propellers?

I’ve passed the wealth of information over to Matt who no doubt will be very pleased with it all… 😉

I on the other hand am frightened…

Thanks again

Stuart…

DH Type 4/4 is a bracket type prop which shares a number of parts with the props used on the Blenheim (4/1, 4/3 & 4/7), Lysander III (4/5), Master II and Martinet (4/8). The problem you may have noticed is that they are all Mercury powered so unlike the Peregrine they’re left handed.

Blade DP54409
Spider P4310-4 (all Type 4 props use variations of the P4310)
Barrel P4300-2 & P4301 (common to all Type 4s)
Piston P4340-3/A/1 (all Type 4 props use variations of the P4340)
Counterweight P4320-2 (all Type 4 props use variations of the P4320)
Counterweight Cap P4321 (common to all Type 4s)
Counterweight Bracket P4322-2 (all Type 4 props use variations of the P4322)
Cylinder P4330-4 (all Type 4 props use variations of the P4330)
CSU AX9
Spinner P30200A/C

Hope that helps (not sure it does).

Anne

Thanks chaps for the heads up on Farnborough – I have spoken with them and I am looking to visit in July on behalf of the group.

Thanks Tony, that’s brilliant.

should do…more pix requested by Matt

******!

It’s never easy is it, got to fight tooth & nail to glean just a tiny bit… :mad::p

Hmmm… Would the present Dunlop have any info on their war wheels?

Thanks for the info Jeepman, though I would be lying if I said it made my day finding that out… ;):D

Stu…

From the original project brief I sent to Mike

Wheels and Tyres
AH 10110 10.5 -10 (fitted only to Whirlwind as mainwheels)
AHO 5007 5.50 -6.00-4 (also fitted to Lysander and Blenheim V)

Can’t remember where I got the info now

Hi Tony…

Any idea what other aircraft used the AH. 10110 as well as the Whirly?

sadly not Stu

Tony your a Star, thank you so much, don’t suppose you’ve got a AH. 10110 tucked away in that Aladins cave of your’s?

Then the tyre issues can be put to bed, done and dusted… :rolleyes:

Stu…

your wish is my command!
This is probably my best marked UK tailwheel.

TonyT always happy to give a home to tail wheels!!!! lol

Hi Matt – Thanks for your offer of help with my registration on the ‘Whirly’ site.

I’m still having problems – the end process where two words are supposed to be visible for me to type in are just not there! as a result the registration fails each time. I’ve just sent you a ‘pm’ with my e-mail address and password preference so you can register me. Would be interested to hear from anyone else suffering problems with registration.
Again – thanks for your time.

Cheers

OK, that’s done – the site should have sent you a confirmation….

More on those props.

These variable-pitch ‘DH’ props were, of course, Hamilton Standard designs under licence. So if anyone can source any of the following prop blades we’d be very happy!

Ideally 6101A -0 to 6101A -3 – please see http://dbdesignbureau.buckmasterfamily.id.au/cac_wirraway.htm

If not, any of the following Hamilton Standard types:

6129
6131

6247
6379
6179
6447

As for existing types, quite amazingly a trawl of the FAA shows only 2 aircraft even certified with 10ft props – the OV10-A (wrong shape blades, sadly) and the Grob Egrett with a four-blader.

Historically, the closest matches I can find are the HS 10′ prop on the Buffalo and (debatably) on the CAC Wirraway. Again, if anyone knows any other types that had 10 foot Hamilton or DH 3-bladers, please let us know!

Essentially, something that looks like this and which gives a 10 foot diameter when mounted on a 3E40 / 3D40 hub or similar:

Edit: Even better would be 3155-6 blades on a 3d40 hub – see second image:

Tony you beautiful man… 😀

Wonderful, just a couple things we need a tad clearer though Tony… 😮

I know call me an awkward ###### but we need to get it spot on, I’ve marked the bits we need to get a lot sharper to make out the detail…

Thank you for your time mate… 😉

Hi No I have not received anything from you at all I thought you had forgotten us.
Dont know why you are having log in trouble try your cookie settings as the site tend to be a bit funny if you dont accept cookies.

Hi Mike
No I certainly haven’t “forgotten” you or the exciting ‘project’ – as I said, I sent (or at least the ‘darn’ (I’m trying to stay polite on here!!:mad:) computer assured me it had sent) you a ‘pm’ back in late February to give you my personal e-mail contact address so you could correspond with me off the ‘Flypast’ website. It would appear this did not get through to you – I’m sorry to hear, so I’ll again try to send you a ‘pm’ with that address – maybe if that succeeds we can continue our chat in a more ‘private’ way (my ‘Shedman’ contact does not wish to use this Forum to communicate – still very ‘sensitive’ issue I’m afraid – sure you’ll understand).

Cheers

I have a couple of none airworthy spit tailwheels lying about somewhere 🙂
