Innovative Design Choices
One notable innovation was the composite rotor. Originally crafted for military purposes, Bell saw potential in its civilian use. Advantages of this rotor include diminished vibrations, enhanced passenger comfort, and an extended operational lifespan. Additionally, the tailboom’s composite construction optimizes weight and stiffness.

With an Allison 250-C47 turboshaft engine at its heart, the Bell 407 touts a commendable seven hundred shp, cruise speeds of 152 mph, and a max speed of 160 mph. These features, coupled with the Full Authority Digital Engine Control (FADEC), enable greater payload capacities, superior performance in elevated temperatures, and unrivaled smoothness in flight.
Variations and Expansions
The Bell 407’s versatility is clear in its range of variants. Notable examples include:
- Eagle 407: Commissioned for Canada’s Eagle Copter, it sports a Honeywell engine.
