BS.100 turbofan alternate history ?

[Archibald]

I'm really fascinated by the P.1154 mighty engine. What if it had survived the doomed VSTOL fighter - and found plenty of alternate applications ?

Bristol Siddeley BS.100 - Wikipedia

en.wikipedia.org

Imagine if the Americans got a big crush on it, and adopted it for all kind of aircraft ? (Nota bene: BS.53 Pegasus was rebranded F402, so BS.100 might be F403...)

That engine had so much potential... for example, how about a STOL C-141 Starlifter ? swapping its TF33s for BS.100s ?

Endless possibilities... 4*15.5 tons of thrust is 62 tons of VSTOL power, which is nothing to sneeze at.

Would PCB be troublesome ? Can't help thinking that, compared to the unfortunate P.1154, hanging them on underwing pylons (C-141 high-wing style, not 707) may alleviate OTL issues like ground erosion and hot gas reingestion...

Long story short: how about 2*BS.100s or 4*BS.100s VSTOL cargo aircraft ?

Brings back memories of the AW.(HS)681!!

Which one of the High Supersonic to Hypersonic aircraft concepts was it that was proposed with a BS100 for low speed and up to about mach 2, then ramjets for faster?

Think it was one of Convair ISINGLASS concepts.

Sounds right...

Ah, here it is! https://www.secretprojects.co.uk/threads/project-isinglass-project-rheinberry.382/post-474758

Convair early availability design R-3. Rocket powered to Mach 9 and 130kft via a 190klb thrust rocket. Subsonic propulsion prior to rocket ignition by a BS.100/8 for travel to rocket ignition spot and after the zoom pass to landing point. No landing a huge glider with an enormous sink rate!
