Come along Mate.

Why cannot I find any 7-cyl engines? Am I supposed to know all their names?


I just use the search facility in Aerofiles itself and is I bring up each page I used the "find'' to search the criteria I am looking for. I've never searched Aerofiles using Google.
Sounds awkwardly slow. You are usually quicker.

Lightning Mate 8th Aug 2011 14:19

A Salmson radial then?

If I named the engine I would expect the aircraft to go within a couple of minutes.

You guys both got something ready to post if I do?


You are usually quicker.
That's how I've always searched if its something I don't recognise or at least have an idea about. May not be the quickest but it works for me!


A Salmson radial then?
Not a Salmson.

Lightning Mate 8th Aug 2011 14:28

You did say it was a 9 cylinder did you not.

RegDep 8th Aug 2011 14:28

My question was technical and about Aerofiles. It seems that searching for a 7-cyl engine aircraft returns zilch. I wonder what is the reason.

I said 9, Ken said 7.

No, RD thought it was 9 cyl...it's actually 7 cyl.

Perhaps using Aerofiles for the search as I do works after all! If I do a search for a 7 cylinder radial I get loads of different engines :)

Ridge Runner 8th Aug 2011 14:35

oh yes, like a Jacobs, por ejemplo!

skytrain10 8th Aug 2011 14:35

Just ran my own test. If I name the engine, you should get it in under 60 seconds!

Not a Jacobs RR.....

Ready, steady.......

skytrain10 8th Aug 2011 14:37

GO.........

Continental A-70

Lightning Mate 8th Aug 2011 14:40

Cabinaire A-70 ?

skytrain10 8th Aug 2011 14:42


Cabinaire A-70
Good enough LM....it's the Paramount Cabinaire A-70, from 1930.
As it was the 3rd line of data on the Aerofiles seach I figured it should not take long. I got Sue to do the search...she found it in 50s!

All yours mate

Lightning Mate 8th Aug 2011 14:52

Nice one Ken. :ok:

Found it without the engine, but only by luck.

A good day so far......

skytrain10 8th Aug 2011 14:53

In that case it was good hunting mate!

Another American offering?

RegDep 8th Aug 2011 14:54

Sobering experience :*

RegDep 8th Aug 2011 14:56

9-cyl radial, cantilever?

Lightning Mate 8th Aug 2011 14:56

Not American this time - bye bye Aerofiles.

7 cylinder radial

almost cantilever

Lightning Mate 8th Aug 2011 15:02


I got Sue to do the search
Better send her down here for a while then!

skytrain10 8th Aug 2011 15:08

French LM?

RegDep 8th Aug 2011 15:11

French? A bit like S.P.C.A. 80?

Lightning Mate 8th Aug 2011 15:11

Not French, but don't go far away.

I feel a map game coming on again - Reg loves it!

Lightning Mate 8th Aug 2011 15:20

Anything else I can do? ;)

RegDep 8th Aug 2011 15:22

Give me the bearing from Aachen. Cannot be far.

Lightning Mate 8th Aug 2011 15:26

173 degrees true.

RegDep 8th Aug 2011 15:30

A Comte?

A-12

Lightning Mate 8th Aug 2011 15:32


A Comte?

Yes.......:ok:

Gimme another number....

RegDep 8th Aug 2011 15:34

AC-12 ……….

Lightning Mate 8th Aug 2011 15:35

No - but you are incredibly close.

C'mon.......1943 retired 1945....

Lightning Mate 8th Aug 2011 15:41

I'm going home.

I'll give it yer.

It's the AC 11V.

The thread is all yours. :ok:

skytrain10 8th Aug 2011 15:42

I was about to say Comte AC-11....but that's from 1931. Comte didn't produce anything during the WWII??

Incidentally this is the AC-11V....the tail is definitely different!

Ridge Runner 8th Aug 2011 15:53

AC-11? poss the AC-11V?

Ridge Runner 8th Aug 2011 15:54

ah... too late... again!!!:(

RegDep 8th Aug 2011 15:59

Skytrain, RR, why don't you post something: I was completely out between Comte CA-2 and CA-12, and am having some problems of multitasking right now.

skytrain10 8th Aug 2011 16:00

You got something Martin...I've got nothing lined up at present so will take me half hour or so.

Ridge Runner 8th Aug 2011 16:16

try this?

A comparitively modern photo....aircraft old as it looks, or something more modern?

RegDep 8th Aug 2011 16:35

In JB, OFSO explains how GPS works and I think it deserves to be repeated here:


How does GPS calculate position ?

The Gnomic Phase Shift uses very small flatulant gnomes located inside the device. Two are required (and actually only one need be flatulant, although usually both are). The second gnome holds a stopwatch. When the first gnome breaks wind, the second gnome starts the watch and listens acutely. When the echo of the wee flatule is received, the second gnome stops the watch. They then argue for a few miliseconds over who will hold the stopwatch the next time, causing the loser's usual grin to turn into a frown, and this "face shift" as it's known, divided by the transit time is shown as your location on your device.

I think that's right ?

I have to say that I thought it was modern, but no! :E

RR

skytrain10 8th Aug 2011 17:41

American RR?

Lightning Mate 8th Aug 2011 17:42


How does GPS calculate position ?

Binary Phase Shift Keying modulation for both navigation data, ephemeris information, and almanac data.

Best accuracy is obtained via LI and L2 precision codes, which enables accurate propagation (ionospheric and atmospheric) error prediction, because the refractive indices of both frequencies may be very accurately predicted and modelled.

This takes me four hours of lecturing!!!

Do you all not admire a person of such superior knowledge......

However comma the JB post is very amusing.

:E:E:E:E


Incidentally this is the AC-11V....the tail is definitely different!

Not with a bit of rudder applied!
