FastFin to Gain FAA Approval

FastFin to Gain FAA Approval 19 Oct, 16, Source:

BLR Aerospace are looking to gain approval from the US Federal Aviation Administration (FAA) next month for the FastFin modification on Airbus Helicopter’s H125.

The FastFin modification combines vortex generators and an aerodynamic cowling on the left side of the tail boom, opposite a strake. This creates a “lateral lift” reports Flight Global. The one side allows a smooth air flow and the other disrupts the air flow. This later lift will reduces the engine power needed, allowing for an additional 64kg to the H125’s maximum 2230kg take-off weight. The modification will be accessible as a factory default option, but can be sold as a retrofit costing $80 000.
