Hi Airman,

Did you mean that you were looking for details on the evolved AW 34, Armstrong Whitworth submission for F9/35? Or are you just looking for info on Armstrong Siddeley's Terrier engine?

All I know about the Terrier is that it was a two-row air-cooled radial design. (I'm guessing that the Terrier was related to the AS Tiger but don't know for sure).

FWIW, the AW 34 was a 39-to-47 foot span (depending upon source) twin-engined taildragger with a two-machinegun turret. Another twin Terrier design (to G.24/35, Botha and Beaufort) was the Avro Type 672 (sort of an enlarged recce bomber Anson).

AW 34 2-view modified from Air International Vol41, No1 (July 1991)

Note library and bookshop are very different things in English. You borrow books from a library and buy them from a bookshop. This appears to be a bookshop like Amazon.

I'm wondering if the Terrier was related to the A-S non-staggered air-cooled radials, the 15-cylinder Hyena, the 21-cylinder Deerhound and the proposed 24-cylinder Wolfhound?

These are the only other A-S engines with non-feline monikers, with the obvious exception of the Mongoose which is neither.

I wondered about that too, the timing of the AW 34 is about right for the Deerhound.

As an alternative, might the Terrier have been intended as a smaller diameter companion to the Tiger using Cheetah cylinders? That is: a twin-row, 5.25" bore x 5.5" stroke engine (compared with the Tiger's 5.5" x 6.0").

It was the use of the Terrier in the Anson-related Avro Type 672 that got me wondering about a possible Cheetah relationship.

than Armstrong Whitworth Terrier could be an unluckely development of Cheetah engines !
