Pratt & Whitney Announces Growth Option 2.0 for F135 Engine

Hits 168

BROOKLYN, N.Y., June 13, 2018. Pratt & Whitney announced a Growth Option 2.0 upgrade for the F135 engine, which powers the fifth generation F-35 Lighting II aircraft, that can provide increased power and thermal management system (PTMS) capacity. The Growth Option 2.0 upgrade can be configured based on customer requirements to offer a range of PTMS improvements, an area which is emerging as a critical enabling capability for future block upgrades to the F-35 aircraft. The near-term iteration of this upgrade can provide a significant improvement in PTMS capacity. 

“As the F-35 program moves forward with the Continuous Capability Development and Delivery (C2D2) strategy, we strive to stay in front of propulsion advances needed to enable F-35 modernization,” said Matthew Bromberg, president, Pratt & Whitney Military Engines. “We’re continuously assessing customer needs and responding with technology options to keep them ahead of evolving threats.” 

Growth Option 2.0 incorporates the same suite of compressor and turbine technologies offered in the previously announcedGrowth Option 1.0, and also brings scaled advances in PTMS capacity while maintaining the same fuel burn (5-6 percent) and thrust improvements (6-10 percent) across the F-35 flight envelope. By selecting from the engine’s full suite of available technologies, F-35 customers can chose the magnitude of PTMS improvements that the mission requires. 

Increases in PTMS  can enable the F-35 to utilize an enhanced spectrum of offensive and defensive weapon system technologies. Growth Option 2.0 can provide a  significant improvement in PTMS capacity in the near-term by utilizing several low-risk technologies ready for Engineering and Manufacturing Development (EMD) today. Pratt & Whitney is also maturing additional technologies that are projected to provide even greater PTMS capability. 

Growth Option 2.0 represents the next iteration of Pratt & Whitney’s Future Adaptive Spiral Technology approach, which enables the timely insertion of next-generation propulsion technologies into current and future platforms. The foundation of this approach is a suite of adaptive engine technologies Pratt & Whitney is developing to meet the demands of range, persistence, survivability, maintainability and advanced weapon systems for the missions of tomorrow. These advanced technologies can be spiraled in as they become available and provide a full range of options for customers, enabling them to maintain the operational edge now and into the future. 

“Our spiral approach allows Pratt & Whitney to offer rapid, iterative upgrades such as Growth Option 1.0 and Growth Option 2.0 that put next generation propulsion technologies into the hands of the warfighter as fast as possible,” added Bromberg. “These upgrades are aligned with the F-35 C2D2 strategy and provide a range of options to meet future weapons system requirements for the F135 engine.”
