The Piasecki-Venzie PV-2 first flew on April 11, 1943, making Frank Piasecki the second American to fly a helicopter of his own design. The PV-2 had a number of advanced features: the first dynamically balanced rotor blades, a rigid tail rotor with a tension-torsion pitch change system, and a full cyclic and collective rotor pitch control. While Piasecki hoped his aircraft would open a new era in personal transportation, his company went in another direction, building large cargo helicopters for the military.
The PV-2 is now on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center.
