Bell has completed nacelle structures for the MV-75 Cheyenne aircraft and initiated gearbox testing across its Texas facilities. This milestone follows the successful integration of flight control systems within the company’s specialized testing labs.
Why it matters
Rigorous testing in simulated environments is essential for reducing technical risks and ensuring the safety of upcoming flight test programs. These procedures allow engineers to validate complex electrical and flight control systems before the aircraft takes to the air.
The gearbox components were manufactured at the Fort Worth facility and instrumented at the Grand Prairie Drive System Test Lab, which opened in 2023. These assemblies were built using digital engineering processes for tooling and part manufacturing.
The players
Bell
Bell is a prominent aerospace manufacturer specializing in vertical lift aircraft and integrated systems for military and commercial use.
The details
The company fitted the MV-75 Cheyenne wings and nacelles together at the Amarillo Assembly Center while concurrently testing flight control computers and large area displays in Arlington. The Weapon System Integration Lab utilizes integrated test benches to confirm electrical and flight systems function correctly under simulated conditions.
Timeline
Bell broke ground on the Drive System Test Lab in 2023.
The Weapon System Integration Lab opened in Arlington in 2024.
Bell announced the completion of structures and initiation of testing on October 14, 2026.
