Rolls-Royce commences ground testing of AE 1107F turboshaft powering Bell’s MV-75 tiltrotor under US Army’s Future Long-Range Assault Aircraft program, targeting 50% greater speed, range over UH-60M Black Hawk.
The upgraded engine—derived from V-22 Osprey AE 1107C—delivers enhanced power density for 6,000+ shp class enabling Mach 0.8 cruise, 800km combat radius with defensive weapons integration.
Tests validate full-authority digital engine control, health monitoring, and ice protection ahead of MV-75 first flight 2027, positioning Rolls-Royce against GE/Pratt in FVL competition.
AE 1107F Evolution Drives Tiltrotor Supremacy
Incremental upgrades focus on hot-section durability, 20% fuel efficiency, and reduced lifecycle costs supporting Army’s 2,300-aircraft modernization. Modular architecture facilitates rapid upgrades matching evolving threats.
Rolls-Royce Tiltrotor Engine Lineage:
| Engine | Power (shp) | Application | Status |
|---|---|---|---|
| AE 1107C | 6,150 | V-22 Osprey | In Service |
| AE 1107F | 6,500+ | MV-75 | Testing 2025 |
| T901 (GE) | 3,000 | Black Hawk | Flight Tests |
FVL Program Accelerates Amid Transformation
Army prioritizes FLRAA over legacy platforms despite ITEP uncertainties. AE 1107F’s proven heritage—millions of Osprey hours—de-risks rapid fielding by decade’s end.
