Pratt Chat: PW1200G Program Celebrates Certification

Friday, June 23, 2017

Jamie Muro, Pratt & Whitney Communications: Hello everyone, and welcome to another edition of Pratt Chat. I'm Jamie Muro with Pratt & Whitney Communications. We are joined today by Bryan Rivard, program manager for the PW1200G, and Bob Grelotti, who is chief engineer of the 1200G. Lot of news about this very exciting program, guys, first, thanks for joining us. What is the big news about the 1200G?

Bryan Rivard, program manager, PW1200G: Well on May 15 we achieved FAA certification of our engine. A long time coming, a lot of work involved and a ton of folks participated.

Bob Grelotti, chief engineer, PW1200G: For us, it's an important milestone. It's sort of the 'end of the beginning' for us. We certainly have a lot of work to do as we go through and develop with the aircraft, but this is the first big step where we can go to the world and say, 'Hey, we have an aircraft that's ready for revenue service.'

Jamie Muro: Bob, learning from other engine programs that have achieved FAA certification, what challenges did you face with this particular program and how pleased are you with how things moved along?

Bob Grelotti: Every program is unique, and certainly the 1200G had its own unique design challenges simply because of the size relative to the other engines but we benefited a lot from the commonality of the 1500 and the 1100G. If we take a look at some of the things that had been learned on those two programs, most of them we've been able to roll into our initial certification program so we are going out the door with a very mature product. We certainly have some work to do, just like every program does as it enters into service, but for us we are starting with a very solid footing.

Bryan Rivard: Common architecture across the GTF platform which folks here are pretty familiar. We absolutely captured some learning from others. I also want to say there are a few items we have fed back, too. We've had a long engine certification development program here. To some extent there is some cross-talk back and forth. I don't want to diminish what this team has done either, in terms of the solutions that they've solved and the challenges we faced. As Bob mentioned, it's the smallest of the packages we've got for GTF engines, and that brings its own challenges. We've got a good integrated flight test program going on right now with Mitsubishi, and we've uncovered some things there that we are going to be able to cross-pollinate back. I think that's all good news. The family plan strategy, whatever you want to call it, is working in that respect.

Jamie Muro: But how historic? You are taking this program from the ground up. We're so close really, to see this finally come to fruition with all the testing and certification that's required, this has got to be really neat to be able to participate in something like this.

Bryan Rivard: As my 6-year-old daughter would say, this is really cool. They thought it was really neat that ... you rarely see big milestones in the news for a long-cycle business like engine development. When I was able to post on Facebook the news press announcement that we certified the engine, I explained it to my daughters and they said, 'Wow! This is what you've been working on.' So it's meaningful in that respect. It takes significant effort. Hundreds of people, thousands of man-hours … to get to Bob's point, we're not done, we have a lot of work left to go, but it feels good.

Bob Grelotti: What I'm looking forward to is taking my family on an MRJ on vacation someday. And that's really what we're focused on. We're trying to get to that point where we are flying people from one place to another. Because that's the important milestone.

Jamie Muro: Well Bob, Bryan, thank you so much for joining us. And thank you everyone for joining us for this edition of Pratt Chat. Take care everybody.
