- Bharat Forge to produce fan blades for Rolls-Royce’s Pearl 10X engine, extending its work from the Pearl 700.
- The Pearl 10X, now in testing ahead of Falcon 10X service in 2027, uses the Advance2 core with new blisk, turbine and 3D-printed combustor technology.
- The deal supports Rolls-Royce’s plan to double India sourcing by 2030 and aligns with the India–UK Defence Industrial Roadmap.
Rolls-Royce has signed a new manufacturing agreement with Bharat Forge Ltd. to produce fan blades for the Pearl 10X business-jet engine, expanding Bharat Forge’s existing work on the Pearl 700.
The contract, signed at Rolls-Royce’s Dahlewitz facility near Berlin—its headquarters for Business Aviation engine programmes—supports the company’s aim to double sourcing from India by 2030.
Expanding Capability And Confidence
Bharat Forge joined the Pearl 700 supply chain in 2020 and delivered its first “zero-defect” fan blade in 2024 after three years of process validation and quality trials, a milestone that established its position among Rolls-Royce’s key global suppliers.
The new agreement now extends that scope to the Pearl 10X, Rolls-Royce’s most powerful business-jet engine yet.
The Pearl 10X completed its first run in 2023 and is undergoing an extensive maturation campaign ahead of Dassault Falcon 10X entry into service, planned for 2027. It combines the Advance2 core with a redesigned low-pressure system to deliver over 18,000 lbf of thrust while achieving about 5 per cent lower fuel consumption than the previous generation.
Technically, the engine features a 10-stage high-pressure compressor with blisks, a two-stage high-pressure turbine, and a combustor fitted with 3D-printed tiles for enhanced cooling and durability—technologies that represent the latest stage of Rolls-Royce’s Advance programme. The Pearl 700, which powers Gulfstream’s G700 and G800, shares the same family architecture and entered service earlier this year after certification by EASA and the FAA.
For Bharat Forge, moving from supplying forgings to delivering finished fan blades reflects years of investment in five-axis machining, titanium processing, non-destructive testing (NDT) and digital quality control. Its aerospace business also supplies forged and machined components to programmes of Safran, Boeing, HAL and DRDO, giving the company a wider industrial base beyond a single OEM. The experience of working with multiple certification systems has strengthened its ability to meet the stringent production demands of Rolls-Royce.
Bharat Forge is currently the only Indian manufacturer producing precision-machined fan-blade components for the Pearl engine family, a position that highlights the level of technology and process control it has achieved within Rolls-Royce’s global network.
This capability stems from sustained investment in advanced manufacturing infrastructure and reflects the company’s goal of delivering globally competitive aerospace solutions from India.
Fan Blades: Precision Parts That Drive Performance
Fan blades define an engine’s efficiency, fuel burn and acoustic footprint. Each blade must withstand high rotational stress, maintain aerodynamic consistency across the set, and resist vibration, corrosion and fatigue. Rolls-Royce’s Pearl series uses advanced titanium alloys that provide strength without excessive weight, machined to aerodynamic profiles that determine airflow through the entire engine.

Producing such blades demands precise control of every stage—from raw material to final inspection. Bharat Forge’s aerospace facilities in Pune and Baramati are equipped for titanium forging, CNC and five-axis machining, heat treatment, metallurgical analysis, NDT, and coordinate-measurement verification.
These processes mirror those used by the company in its power-equipment and heavy-engine divisions, where it manufactures high-load rotating parts such as turbine shafts and crank systems. This cross-domain experience has built a strong culture of precision manufacturing that directly supports its work on aero-engine components.
Achieving a “zero-defect” standard, as Bharat Forge did on the Pearl 700, means every fan blade meets dimensional, metallurgical and surface-finish criteria without rework.
The Pearl 10X brings tighter aerodynamic tolerances and smoother surface requirements, which the company now has the equipment and workforce training to achieve.
Each blade undergoes sequential inspection using laser metrology and digital tracking, ensuring total traceability—a necessity for safety-critical hardware.
India Advances In Aero-Engine Work
The partnership fits squarely within Rolls-Royce’s plan to increase its India sourcing in the next five years. The company already partners with Godrej & Boyce, Tata Advanced Systems Ltd. (TASL) and Hindustan Aeronautics Ltd. (HAL) for precision components and engineering services. Across India, more than 1,400 Rolls-Royce engines power aircraft for the armed forces, supported by a workforce of over 4,000 people, including 2,800 engineers who contribute to global development programmes.
For Bharat Forge, the Pearl 10X contract arrives as it builds a new aerospace ring-rolling and forging facility at Baramati, scheduled to begin operations in 2026. The plant will produce large-diameter titanium and nickel-alloy rings used in engine casings, compressor sections and structural components. By manufacturing these critical rings domestically, Bharat Forge aims to reduce import dependency, shorten production cycles and strengthen India’s position in high-value aerospace forging.
Amit Kalyani, Vice Chairman and Joint Managing Director of Bharat Forge, Ltd. said:
“This expanded partnership with Rolls-Royce reflects our shared commitment to engineering excellence and long-term collaboration. We are proud to support the Pearl engine family, which represents the future of high-performance aviation.”
The move also aligns with the India–UK Defence Industrial Roadmap, which promotes joint manufacturing and technology partnerships between the two nations. Rolls-Royce’s expanding Indian network fits that policy direction, combining British engine design expertise with Indian manufacturing scale.
India’s aerospace industry has long focused on airframes and standard components. The move into rotating hardware and hot-section components now marks a step into the most demanding domain of engine manufacturing. Such work brings higher value addition and deeper skill development, from metallurgy and tooling to advanced inspection and data-driven process control.
Deeper Collaboration, Broader Capability
The Rolls-Royce–Bharat Forge partnership illustrates a new phase of cooperation between global engine makers and Indian manufacturers. What began as a parts supply relationship has matured into the manufacture of components that sit at the heart of an engine’s performance.
Speaking about the partnership, Sashi Mukundan, Executive Vice President – Transformation, Rolls-Royce India said:
“Rolls-Royce is delighted to deepen its partnership with Bharat Forge towards advancing the ‘Make in India’ vision. This new contract reflects our commitment to developing world-class manufacturing capabilities in India, with a shared vision of delivering state-of-the-art aerospace components to the global supply chain ecosystem.”
For Rolls-Royce, it strengthens the company’s supply base for the Pearl engine family, which reinforces its position in the long-range business-jet market. For Bharat Forge, it represents tangible progress from heavy-industrial engineering to aerospace-grade production, validating a decade of investment in materials, machinery and workforce training. The company plans to build on this momentum through new long-term partnerships with leading OEMs and Tier-1 suppliers worldwide, expanding its presence in the global aerospace market.
The agreement also signals how India’s “Make in India” initiative is moving beyond assembly to genuine high-precision production.
With advanced forgings, ring-rolling, and machining now underway, Indian manufacturers are positioning themselves not only as cost-effective suppliers but also as contributors to next-generation engine technology.
As the Pearl 10X advances toward certification and production, each fan blade leaving Bharat Forge’s factory will represent more than a component—it will embody the quiet transformation of India’s role in global aviation manufacturing.
