Looking for a Turbofan engine
« on: March 25, 2021, 12:27:48 PM »
I'm thinking about doing a conversion, a single engined version of a twin engined jet.

I need a relatively powerful turbofan engine in the late 1960s-early 1970s, approximately 12,000 lbs thrust.  Does anybody know of any contenders?

Thanks.  That answers the question!

CF34-8 or CF34-10, you'll find these on CRJ-700/900

A JT8D variant is the first one that comes to mind, though I suspect there are other engines out there that would fit your criteria.  I do't believe the CF34 existed in the time frame specified.

Options based upon being available in 1970 and with thrust range in 12K-16K lb range:

  • P&W TF30
  • Allison TF41
  • RR Spey
  • P&W JT8D or Volvo RM8 derivative
  • RR RB.203 Trent
  • RR/SNECMA M45G

I've left off large fans such as GE TF39/CF6, P&W JT9D or RR RB211.

Nah.  CF34 didn't run until 1982
