Building Better eVTOL Batteries for UAM

Two Salts are Better Than One

through 500 cycles, theGen-2 system displayed signs of polarization and capacity loss, particularly during high-rate hover and descent phases of operations. By comparison, the dual-salt electrolyte system was stable retaining capacity and exhibiting low polarization potentials through the flight cycle.

6 Things the State of Illinois Needs to Do to Advance AAM

The ‘Land of Lincoln’ charts a course toward Advanced Air Mobility

Home to nearly 9,000,000 people, metropolitan Chicago is, theoretically, an urban air mobility (UAM) air taxi operator’s dream. Or at least it would be, were it not for Chicago’s brutally cold winters. Winter temperatures average at, or just above, freezing during the day and -5°C (about 20-25°F) at night. And, then there’s the wind. In…

Eyes wide shut -- bad eVTOL pilot. Bad pilot.

Urban Air Mobility Will Stretch Pilot Fatigue Management in New Ways

Short-haul, multiple takeoffs and landings per day, and revolutionary, new eVTOL technologies will test pilot’s resilience in radically new ways.

Imagine yourself a taxi driver in New York City, London, Berlin, or Tokyo; dozens, maybe hundreds of trips in an 8-, 10-, maybe even 12-hour day. You’re doing what you can, as the movie Cabaret song said, to “earn a mark, a yen, a buck, or a pound.” Now, flash-forward to 2027 or 2030 and…

How Much Noise Will a Single Rotor Make When a Single Rotor Makes Noise?

Use the NASA RVLT Conceptual Design Toolchain to Predict Best Practices

In their paper, “Best Practices for Predicting Acoustics of a Single Rotor Using the NASA RVLT Conceptual Design Toolchain” presented at the Vertical Flight Society’s 6th Decennial Aeromechanics Specialists’ Conference held in Santa Clara, California in February 2024, NASA aerospace engineers Lauren Weist, Natasha Schatzman, and Dorsa Shirazi detailed the results of their study intended…
