A slew of patent awards for Bell over recent months – including a biplane tiltrotor, a pusher propeller drivetrain and an anti-torque tail rotor that can be turned through 90° – highlight the range of innovations potentially being considered by the helicopter manufacturer.
Heading up the weight range means these medium-class helicopters are more capable but more complex – and come with a bigger price ticket. Despite this, there are big sellers in this category, alongside new entrants.
Arguably the most competitive part of the helicopter market, the light-single segment is, however, not necessarily blessed with the most modern designs. Nonetheless, new models are in development which will bring innovation to the sector.
