Whisper Aero, a Tennessee-based tech start-up developing what it claims will be the quietest electric propulsion system on the market, is getting ready to finally offer the public a taste of its secret sauce. 

Having quietly worked on its propulsion technology since February 2021, the company has yet to reveal any details about its product, such as the expected power output and noise levels. Now the company is almost ready to reveal some of its secrets. Ian Villa, Whisper Aero’s COO and chief product officer, told FutureFlight that the company will be revealing new details about its propulsors “toward the end of March or early April.”
