Whisper Aero Secures NASA Contract to Develop Quietest Fan for Space Environments
In the vast expanse of space, silence is a rare commodity. The hum of life support systems, electronic fans, radios, and crew activity can create a noisy environment within crewed spacecraft. NASA has long been concerned about the impact of this noise on its astronauts, leading to efforts to make the International Space Station quieter over the years.
However, the quest for a truly quiet space environment continues, with Whisper Aero, a Tennessee-based startup renowned for its ultra-quiet electric propulsors, stepping up to the challenge. The company has secured a new NASA contract to design a fan that is not only quiet but also suitable for crewed space environments. By the end of the six-month project, Whisper aims to present prototype parts to NASA for evaluation, with plans to move forward to testing a design prototype next year.
In Phase 2 of the project, NASA and Whisper will compare the acoustic and aerodynamic estimates from the Phase 1 contract with measurements from a baseline NASA Spacecraft Cabin Ventilation Fan. Whisper's COO, Ian Villa, emphasized the importance of utilizing innovative technology to address noise and efficiency challenges in space, similar to those faced on Earth.
According to recent research, noise levels in the crewed sections of the International Space Station averaged around 73 decibels (dB). NASA has developed a space fan that achieves 66 dB at 2 feet, while Whisper aims to surpass this by reaching 61 dB at 2 feet with a 75% increase in efficiency. This means a lighter, smaller fan without the need for bulky silencers. Whisper's technology, adapted from its terrestrial applications, includes a shrouded fan capable of minimizing tones and operating continuously for years in the harsh space environment.
As private space station developers prepare to replace the ISS in the coming years, Whisper's technology could play a crucial role in creating a more comfortable and efficient space environment. The company's mission of delivering cleaner, quieter air delivery aligns with the growing demand for luxury space tourism experiences, where noise quality and level can impact customer satisfaction.
NASA is also exploring quieter fan options for spacesuits, highlighting the importance of addressing noise challenges early in the design process. Villa acknowledged the significance of NASA's proactive approach to noise reduction in spacecraft, emphasizing the need for industry-wide collaboration to create a more pleasant and efficient space environment.
In conclusion, Whisper Aero's initiative to develop the quietest fan for space environments not only benefits astronauts but also paves the way for a more enjoyable and efficient space travel experience. By prioritizing noise reduction and efficiency, companies can enhance the overall quality of their space missions and attract a wider range of customers, from professional astronauts to luxury space tourists. As technology continues to advance, the future of space travel looks brighter and quieter than ever before.
