Sikorsky S-67 Blackhawk
The aircraft was designed as a low-cost tactical helicopter demonstrator, based around the rotors, engines, hydraulic/electrical systems, and drive train of the S-61/H-3 series aircraft. It was a "semi-compund" design in that it was equipped with a lifting wing to off-load the rotor in high speed flight, but did not feature any auxiliary propulsion systems.
The main wheels were fully retractable but the tail wheel was fixed.
