NASA contracts Whisper Aero to design quieter cabin fans

Whisper Aero believes its ultraquiet propulsion system could enable sustainable regional flights.

The Whisper Aero Flight Test Center will be an 8,000-square-foot hangar located at Crossville Memorial Airport (KCSV), right next door to the company’s headquarters in Crossville, Tennessee.

Whisper Aero has lifted the curtains on a new aircraft concept known as the Whisper Jet, which utilizes a next-generation, ultraquiet propulsion system that the Tennessee-based start-up has been developing in secrecy for the past two years.

Whisper Aero, a Tennessee start-up, spent the last two years developing a propulsion system that it says is quieter and more efficient than any other. Now it has finally revealed part of its secret: electric ducted fans.

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.

The Tennessee-based start-up has raised $7.5 million from venture capitalists and aims to bring the first of its electric thruster propulsion units to market by 2023.
