Tennessee Patent of the Month – May 2025
A new U.S. patent from Whisper Aero Inc. could reshape how we think about quiet propulsion. U.S. Patent No. 12291977, titled ‘Propulsor fan array’, introduces a breakthrough in reducing noise from electric ducted fans—key components in next-generation aircraft and spacecraft. The innovation lies in a subtle yet powerful design tweak: tensioning the fan blade tips to maintain their pitch during operation. This stability minimizes the noise typically caused by blade angle shifts under load, offering a quieter thrust solution.
Quieter Skies and Space Missions
Whisper Aero’s fan array design addresses a longstanding issue in aerospace: excessive noise from propulsion systems. Traditional fans often produce disruptive sounds due to blade deformation during operation. By keeping the blade pitch consistent, this new design significantly reduces such noise, enhancing comfort for passengers and astronauts alike. This advancement is particularly relevant for space missions, where noise reduction is crucial for communication and crew well-being.
Real-World Impact
The implications of this patent extend beyond theoretical design. Whisper Aero has already secured a NASA contract to develop ultra-quiet, efficient fans for spacecraft cabin ventilation, aiming for a sound pressure level of 61 decibels at two feet away. This aligns with the company’s broader mission to deliver cleaner, quieter, and more efficient propulsion systems across various applications, from regional air mobility to defense. The patented fan array is a testament to Whisper Aero’s commitment to innovation and its potential to set new standards in propulsion technology.
Looking Ahead
As the aerospace industry seeks sustainable and quiet propulsion solutions, Whisper Aero’s propulsor fan array stands out as a promising development. By addressing noise at the design level, this technology not only improves passenger and crew experience but also opens doors to broader applications in electric aviation and space exploration. With this patent, Whisper Aero reinforces its position at the forefront of propulsion innovation.
