The P-V Engineering Forum PV-2, or Piasecki PV-2, was the brain child of Frank Piasecki. The PV-2 is best know for being the second successful helicopter flown in the United States. The PV-2 first flew on April 11, 1943.^[1] Developed as a technology demonstrator, the PV-2 brought several new features such as 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. ^[2]

The PV-2 is now on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center
