Coquin de Philou !  je ne trouve pas cette photo là dans ta référence !  quand est-ce qu'on aura droit à une photo équivalente avec notre Gazelle ( ça c'est possible Hillico ) 

et un HIL ( c'est c'est moins hélico ) !

Original comme solution (expérimentale) pour opérer avec des hélicoptères dans (sur ?) la jungle !

The newest V-280 tiltrotor has over twice the speed and range as the current vertical lift fleet. Currently, the new Bell’s generation of combat aircraft offers strategic projection with tactical execution for unconventional performance.

Sikorsky-Boeing reveals refined SB>1 helicopter  It is called “Defiant X”, a proposed refined version of the current Sikorsky and Boeing SB>1 coaxial compound helicopter. The design is the team’s ultimate pitch to replace the US Army’s UH-60 Black Hawk helicopters with a speedy Future Long Range Assault Aircraft (FLRAA).

Sikorsky-Boeing s'approche du retour aux essais FLRAA en soufflerie

Sikorsky-Boeing is returning to the US Air Force’s (USAF’s) National Full-Scale Aerodynamics Complex (NFAC), located at Moffett Field in Mountain View, California, in March for additional wind tunnel testing of its US Army Future Long Range Assault Aircraft (FLRAA) effort.

Hirschberg noted that it is expensive for companies to perform wind tunnel testing. Not only does a company have to rent a wind tunnel facility, but it must invest substantial amounts of money to create a sophisticated subscale model that accurately replicates, for example, the mechanical gearing inside a helicopter.
