Following analysis of data obtained during two weeks of testing as part of NASA’s National Advanced Air Mobility Campaign, Joby’s aircraft was shown to have achieved the breakthrough low-noise goals that the society had set itself.
The plane recorded the equivalent of 45.2 A-weighted decibels (dBA) from an altitude of 1,640 feet (500 meters) at a speed of 100 knots, a noise level that Joby says will be barely noticeable. in the surrounding environment of cities.
NASA engineers also measured the aircraft’s acoustic profile during the planned takeoff and landing profiles to be less than 65 dBA, a noise level comparable to normal conversation, at a distance of 330 feet (100 meters) of the flight path.
“We are thrilled to show the world how quiet our aircraft is by working with NASA to take these measurements,” said JoeBen Bevirt, Founder and CEO of Joby.
“With such a quiet aircraft, we have the opportunity to completely rethink the way we live and travel today, helping to make flying an everyday reality in and around cities. This is a game-changer.”
All measurements were made using NASA’s Mobile Acoustics Facility, with more than 50 pressure ground plate microphones placed in a grid array at Joby’s Electric Flight Base near Big Sur, California .
To measure the noise footprint of the Joby aircraft during the aerial flight, it flew over the grid array six times at a speed of 100 knots and at low altitude to measure as much noise from the aircraft above the background atmosphere as possible. Data recorded from the field of omnidirectional microphones was then processed by NASA into an “acoustic hemisphere”, representing sound emission in all directions below the aircraft at a radius of 100 feet. Joby then applied standard processing techniques for spherical spreading and atmospheric attenuation, resulting in an average free-field acoustic reading of 45.2 dBA at 1640 feet (500 meters).
Joby also performed more than 20 takeoff and landing tests above the grid array, using a variety of acceleration rates and climb angles to allow NASA to capture representative acoustics of the procedures. probable operations. This data will be used to adjust flight software and take-off and landing procedures for further low-noise optimization.
From day one, the Joby aircraft has been designed with acoustics in mind, with the number of propellers and blades, blade shape and radius, top speeds and disk loading of the aircraft, all selected to minimize its acoustic footprint and enhance sound character. product. Each of the six propellers can also individually adjust its pitch, rotational speed and blade pitch to avoid blade-vortex interactions that contribute to the acoustic footprint of traditional helicopters.
More details regarding the procedures and measurements will be published by Joby and NASA in technical papers to be presented at industry conferences this summer.
Joby’s piloted five-seat eVTOL aircraft can carry four passengers at speeds of up to 200 mph, with a maximum range of 150 miles on a single charge and zero operating emissions. With more than 10 years of development and more than a thousand flight tests carried out, Joby aims to launch its air ridesharing service in 2024.
