Out of curiosity, I decided to take a look at the Defiant footprint, in comparison to the Blackhawk. However, unlike Bell on the Valor, I can’t find a published number for the main rotor diameter on the Defiant.
There are published photos of both the Blackhawk and Defiant next to each other by Sikorsky, however, most are taken from a perspective that makes it difficult to judge the main rotor size. I finally found one plan view photo, and based on the Blackhawk rotor diameter being 53.66 feet in diameter, I am estimating the defiant rotor diameter at 65.23 feet.
Does anyone know what the Defiant main rotor diameter is?
I find it odd that the tail pusher prop diameter of 11 feet is published, but I can find no reference to the main rotor diameter.
The pusher won't affect the size of the footprint but main rotor diameter will, I suspect they are being circumspect on purpose.
