In a significant advancement for military aviation, Safran has introduced an enhanced version of the M88 engine, specifically designed for upcoming iterations of the Rafale fighter jet. Dubbed the M88 T-REX, this new engine variant is engineered to produce an impressive thrust of 9 metric tons, or 88.2 kilonewtons, equivalent to approximately 19,841.6 pounds when afterburners are engaged. This marks a substantial 20 percent increase over the existing M88 model, which currently powers the Rafale aircraft.
The Rafale, which weighs in at 25 tons, utilizes two M88 engines, each delivering 75 kilonewtons (around 16,900 pounds) of thrust. The upgraded M88 T-REX is poised to address the power requirements of future Rafale models, particularly the anticipated Rafale 5, allowing for the integration of advanced sensors, communication systems, and digital processing capabilities. Notably, this enhancement will occur while maintaining the established size and shape of the existing engine, ensuring compatibility with the Rafale’s original airframe design.
Safran reassures stakeholders that the costs and fundamental characteristics of the new engine will largely remain consistent with the current variant. According to Christophe Bruneau, the executive vice president of the Military Engines Division at Safran Aircraft Engines, the launch of the M88 T-REX project is a proud moment for the company. “This engine will push the boundaries of the M88’s performance to meet the evolving needs of our armed forces customers in an increasingly unstable geopolitical context,” he stated. Bruneau emphasized that the development of the M88 T-REX will also enhance Safran’s technology portfolio, which in turn will benefit the entire range of their products and reinforce national sovereignty.
The upgrades for enhanced thrust in the M88 T-REX will include a re-engineered low-pressure compressor to increase airflow intake, alongside the application of new materials and advanced cooling circuits. These improvements will enable the engine’s high-pressure turbine to function at elevated temperatures, while the nozzle will be aerodynamically optimized. Safran has asserted that these enhancements will not compromise the M88’s existing advantages in terms of size, modularity, fuel efficiency, and cost of ownership. Furthermore, the commonality between the modules of the two engine variants will streamline maintenance and fleet management processes.
The qualification of the M88 T-REX aligns strategically with the planned induction of the Rafale F5 in the early 2030s. In preparation for the engine’s development, Safran is actively engaging in risk reduction studies, ensuring that the transition to this advanced engine variant is smooth and efficient. As the geopolitical landscape continues to evolve, the M88 T-REX engine represents a forward-looking commitment to enhancing aerial combat capabilities and sustaining technological leadership in the defense sector.
