Preparations for Next Moonwalk Simulations Underway (and Underwater)

A woman sits in a seat with straps atop a metal platform that is tilted to the right side with three base pieces. Her feet rest on a metal platform. Yellow metal bars surround the platform. The woman is wearing black pants and a black and white vest, as well as black virtual reality goggles and a headset.

Research continues to better understand how humans may interact with these new types of aircraft.

NASA’s Advanced Air Mobility vision involves the skies above the U.S. filled with new types of aircraft, including air taxis. But making that vision a reality involves ensuring that people will actually want to ride these aircraft – which is why NASA has been working to evaluate comfort, to see what passengers will and won’t tolerate.

NASA is conducting a series of studies to understand how air taxi motion, vibration, and other factors affect ride comfort. The agency will provide the data it gathers to industry and others to guide the design and operational practices for future air taxis.

“The results of this study can guide air taxi companies to design aircraft that take off, land, and respond to winds and gusts in a way that is comfortable for the passengers,” said Curt Hanson, senior flight controls researcher for this project based at NASA’s Armstrong Flight Research Center in Edwards, California. “Passengers who enjoy their experience in an air taxi are more likely to become repeat riders, which will help the industry grow.”

The air taxi comfort research team uses NASA Armstrong’s Ride Quality Laboratory as well as the Human Vibration Lab and Vertical Motion Simulator at NASA’s Ames Research Center in California’s Silicon Valley to study passenger response to ride quality, as well as how easily and precisely a pilot can control and maneuver aircraft.

After pilots checked out the simulator setup, the research team conducted a study in October where NASA employees volunteered to participate as passengers to experience the virtual air taxi flights and then describe their comfort level to the researchers.

The man holds a piece of paper in one hand and his other hand is stretched out to the side. Behind them sits a metal platform with steps, which houses a black seat.

Behind them is the air taxi passenger ride quality simulator in NASA Armstrong’s Ride Quality Laboratory. Studies continue to better understand passenger comfort for future air taxi rides.

Using this testing, the team produced an initial study that found a relationship between levels of sudden vertical motion and passenger discomfort. More data collection is needed to understand the combined effect of motion, vibration, and other factors on passenger comfort.

“In the Vertical Motion Simulator, we can investigate how technology and aircraft design choices affect the handling qualities of the aircraft, generate data as pilots maneuver the air taxi models under realistic conditions, and then use this to further investigate passenger comfort in the Ride Quality and Human Vibration Labs,” said Carlos Malpica, senior rotorcraft flight dynamics researcher for this effort based at NASA Ames.

This work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.
