BR710 engine

Sat Jul 15, 2017 7:16 pm

Hi all,

I'm looking for the BR710 engine fuel mass flow rate and the cost of the engine.

Any of the experts have any idea? Thanks in advance!

Hi!

BR710 on Global 6000 airframe has a takeoff thrust FF between 5500 and 6000 PPH (per engine, of course) and in the range of 1500-2000 PPH per engine in normal cruise.

No idea about the cost of the engine.

Hope it helps!

I always wondered why this series of engine never found its way onto commercial aircraft (save the 717). Seems like a perfect powerplant for RJs and maybe even smaller narrowbodies. Ineffective sales strrategy on RR’s part? Seemed like a fine product.

https://www.myaeroengine.com/OnWingCare ... 2-5746.pdf says:

Inlet mass flow: 432 lb/s

Price was already mentioned in post:
viewtopic.php?t=742957#p10695963

Since the data is about 10 years old, I think the price would be up by some 20-30%, still considering the discounts on large orders, or none, I'd say 2.5mln bucks is as good estimation as you can probably get.

Cheers,
Adam

It's really a high altitude, high Mach engine originally designed for business jets, not airliners.

Why is the BR7xx so good at hot turns, ~17 cycles a day? Is it more than low pressure ratio, lower bypass, compared to CFM56, Trent, V2500, etc.?

An HA pilot I know recently corrected me (the topic was BR 715s on B712 frames), saying HA's 712s have BR 725 engines.

I thought the BR 725's EIS was on the G650 in 2012, after the B717 production ended (last delivery in 2006 to AirTran).

717s definitely don't have the 725, only BR 715s.

Thanks... as I thought. Now I know why the FO had a puzzled look as he overhead our conversation.
