How Pratt & Whitney is using digital tools to speed development of its adaptive engine



How digital helps meet demand
Digital design addresses communication problems that have historically hindered engine development. On a typical program, as many as 1,500 engineers would work with hundreds of vendors across dozens of software platforms and even paper documents. They had no way to combine their information into a single place where everyone could see it.
Pratt & Whitney fixed that problem through a digital collaborative environment. Engineers now have a dashboard-like interface where teams can share information and work together in real time. Their goal was to develop XA103 in a way that would reduce errors, identify problems earlier, shorten turnaround times and improve communication between internal teams, vendors and the Air Force.
The digital collaborative environment takes decades of computer-aided design work that’s been happening across the company and brings them together for greater results.
“What is happening in the digital transformation that we are going through now,” Johnson said, “is that we’re having a more concerted effort to connect some of those digital tools to have them optimize with each other.”
The team completed the program’s detailed design review in early 2025 and is now preparing to build a prototype that will continue to be tested and refined until the engine’s ground test, which is expected in the late 2020s.

The digital collaborative workspace is just one way the team is working differently. They’ve also realized time savings by bringing testing and validation earlier in the design process instead of adding test instrumentation after the engine has been designed. 
Another key component of the program is its use of model-based systems, or 3D digital models that contain all the relevant program details and data. This will simplify reporting because years of test data will be neatly stored and easily accessible in the model and make it easier for onboarding teammates mid-project.
“Our current engine is over 2,000 pieces of instrumentation sensors – all with their own little story that goes along with them and why they’re needed. In the past, you’d have somebody at the center of all of that who has lived it,” Seipt said. “Now, even if a new person comes onto the program that hasn’t lived the last four or five years of history with that particular test asset, they can jump right in and have those impact analyses available immediately.”
Model-based systems will help streamline the supply chain as well. Chris Scott, from Pratt & Whitney’s supply chain team, is training roughly 200 suppliers for model-based definition for manufacturing and inspection – a method that includes manufacturing data in a 3D model rather than traditional, hard-copy blueprints. Because the models are machine readable, the supplier doesn’t have to recreate the paper blueprint with their software, which means fewer errors in translation, and they can begin working as soon as they receive the technical data package from Pratt & Whitney.

Industry studies show the time between order receipt and delivery could be cut in half when using model-based technologies.
“There’s a lot of manual handoff of information. Model-based definition for manufacturing and inspection really focuses on automating a lot of those processes,” Scott said. “We want to get away from doing data-mining activities and really focus on making decisions with relevant information in front of us in real time. There’s a lot of opportunity to speed up that process and get to market faster.”
Pratt & Whitney plans to use a digital shop floor that will automate manufacturing – as it’s already doing across several sites including Asheville, North Carolina, for airfoil production and in Oklahoma City for maintenance, repair and overhaul.
Recreating the F119 experience
The move to digital processes has made it easier for the Air Force to collaborate with Pratt & Whitney – something both parties enjoyed in the 1990s, during the development of the F119 engine for the F-22 Raptor.
“They wanted that experience again not only from the performance of the engine but from the interaction with our team,” Johnson said. “We took that to heart as we started this program, and the digital tools have given us a way to step that up.”
The digital collaborative environment allows the Air Force to access program files and provide feedback at any time through a classified system. That transparency, coupled with Pratt & Whitney’s history in military engines, has strengthened trust and shown the team’s commitment to providing new capabilities quickly.
“We’re creating perhaps the most complicated machines on the face of the planet, and yet they are some of the most reliable machines on the planet,” Johnson said. “That’s important because our team is committed to making sure the warfighter has what they need to complete their mission and come home safely. You want to make sure that it’s going to work, and you want to make sure that it’s going to get done on time – Pratt & Whitney is the place that you can get that dependable engine.”

There is a video that I can not post but I do expect this engine to be for the F-47
