Piasecki and the Hydrogen-Powered Helicopter

Hydrogen Helicopter 

The PA-890 eVTOL Compound Helicopter

Several high-profile start-ups have focused on battery-powered eVTOL aircraft, but the low energy density of batteries limits their application to small, short-range vehicles suitable for the urban air mobility market, with mission legs as short as 25 nm. Piasecki, meanwhile, has focused on developing a practical eVTOL aircraft to disrupt the turbine helicopter market: the PA-890 eVTOL hydrogen fuel cell–powered compound helicopter (pictured at the top of this article).

The PA-890 features:

  • A design mission capability exceeding 200 nm plus IFR reserve
  • A 50% reduction in operating cost per flight hour
  • A significantly reduced acoustic signature
  • Zero direct emissions.
