RAAF English Electric Canberra 'SLEP Program'
elmayerle:
Just a thought; for the time frame you are considering, suitably sized turbofan engines do not yet exist and I doubt the RAAF would want to go the route of the RB-57F; so consider re-engining with J52's and get the same thrust in a smaller package. If there was a second re-engining in the late Seventies or early Eighties, I could see dry F404s or RB199s being used.

Speys were available from approximate 1964 onwards. Conways were available before that in the late 1950s. Both were turbofan engines.
Basically you'd have at this point in time from the UK, the following engines. All could fit into the wings of the Canberra (with a little bit of a shoehorn):
Engine: Rolls-Royce Avon R.A.7 Mk.109 Rolls Royce Conway Rco.12 Spey Mk 250 Rolls Royce Olympus 101Length: 126 in (3,200 mm) 132.4 in (3,360 mm) 111 in (2,819.4 mm) 127.1 in (10.59 ft; 3.23 m) Diameter: 35.7 in (907 mm) 42 in (1,100 mm) 43.0 in (1092.2 mm) 40 in (3.3 ft; 1.0 m) Dry weight: 2,890 lb (1,310 kg) 4,544 lb (2,061 kg) 4,093 lb (1856 kg) 3,615 lb (1,640 kg) Maximum thrust: 7,400 lbf (36 kN) 17,500 lb (77.8 kN) @ 9980 rpm (100%) 12,140 lbf (54 kN) 11,000 lbf (49 kN)

Can you post a link to this please.

Well they could support AS.30s which isn't that far removed in size:
