Delson Aeronautics wins USD25,000 competition prize for low-noise drone rotors

By Chris Stonor

Delson Aeronautics, a Canadian firm at the forefront of creating “almost silent drone rotors” has just won a start-up competition boasting a prize of USD25,000, reports social media.

The Holy Grail within the Industry is to create silent moving rotors for drones when the “noise factor” is a major criticism from the public and may slow down the industry’s expansion, especially around urban areas.

That irritating “whiny bee buzzing sound” is enough to put anyone’s nerves on edge, but Delson is close to making a breakthrough for a silent drone sky. Its website states, “We  envision a future where aircraft soar so silently above they seem as if designed by nature, not human. This is because we believe the closer our technology represents the characteristics of nature, the better our future will be.”

The company, founded by Michael Deloyer, has developed “a novel series of ultra-quiet, high-thrust propulsion systems, to enable new capabilities in clean aircraft design.” The website continues, “We find it inconceivable to think our current means of propulsion are the best we will ever create. If we are to truly realise the aerial future we envision, a fundamental change is required.”

The recognition of Delson’s work via the accolade of this prize is another step towards the company realising its dream, thanks to the Mitsubishi Chemical Advanced Materials (MCAM) who advertised its KyronMAX Challenge at the beginning of the year. The clarion call was for engineers and designers “to share designs to solve a manufacturing or engineering challenge.”

After many submissions, just 14 finalists were selected and Delson gained the top spot, particularly when the company’s  tender included recycling the UAV blades.

Deloyer told dronedj, “I’m surprised and grateful. It’s just great recognition, to be honest, of the three-plus years of designing these blades silently in the background. The prize money will assist the company through its next important step.”

He continued, “Even when it’s not loud, the noise of drone propellers is always annoying as it sounds like mosquitoes and nobody likes that. These blades just don’t produce that sound, ever.”

The patent-pending blade design method results in an average 10 dB sound reduction or 50 percent quieter relative to equivalently sized conventional UAV propeller blades.

With the manufacturing support from MCAM, Delson can research further these manufacturing methods and materials capabilities. The aim is to produce blades in select sizes for trialling on various UAV airframes, amounting to an extremely lightweight, low cost, scalable, and sustainable solution to manufacturing the Delson ultra-quiet propellers.
