Which engine, Garrett or PT6A?

Post by Not1011 » Sat Nov 17, 2018 1:19 am

I'm confused. Which engine is better, the PT6A or the TPE-331? Noise aside (the Garrett's made me a little bit deaf).

I already know the technical aspects, I just want to know which is better overall?
I did not sell very well, so Lockheed killed me. I'm the reason it doesn't make airliners anymore.

Random stuff:
1. They ain't "sharklets", like Turbofan said.
2. The Tu-114 should really go back into service in a redesigned form.
3. The L-1011 should also return, too.
4. My posts are repeatedly deleted on the AM3 forum.
5. Concorde must return!
6. Fegelein can never die, even when Hitler himself tries to kill him. (Downfall parodies)
7. Embraer should restart production of the EMB-110 and EMB-120, as those are my two favourite prop planes.

Considering the sales I think you have an answer.

I have first hand experience with the highs and lows of the PT6C and I can confirm in a medium helo it's the best option of its era. The newest stuff coming online like the new Safran engines may change this
YSRepo Supreme Overlord
YSFHQ Elected Overlord
Overlord of VMFA-125 (CVW-171)
Previously Supreme Overlord of 323rd CAW

I see that you have experience with the PT6C, a turboshaft variant. It's mostly identical to the PT6A, except that the PT6C obviously drives a helo rotor.

The TPE-331 doesn't have a turboshaft variant, which is strange, given that most turboprop engines also have a turboshaft variant, or vice versa. The Astazou, the Allison 250, the CT7, etc. Garrett did plan a turboshaft TPE-331 but just cancelled it.

Imagine the noise that thing would make stuck into a helicopter.
