Having a robust charging infrastructure, an energy matrix that supports demand levels and reducing supply times are three of the great challenges that electric mobility still has to face in order to become widespread on a global scale.

Against this backdrop, companies, the public sector and scientific institutions are making significant investments and efforts to present innovations that will overcome these difficulties.

From Purdue University, in Indiana, USA, researchers were inspired by a NASA flux boiling module to reduce the amount of heat that travels through the cables to push 1400 amperes, compared to the 520 amperes that are delivered in the most advanced current chargers.

This NASA manufactured system was initially built for the International Space Station for the issue of orbiting spacecraft. This technology piqued the interest of Issam Mudawar, a professor of mechanical engineering at Purdue, who built a prototype in 2021 capable of powering electric vehicles quickly.

Record-time Charging

The team, sponsored by NASA’s Physical and Biological Sciences Division and led by Mudawar, developed the Flow Boiling and Condensation Experiment (FBCE) to enable two-phase fluid flow and heat transfer experiments to be conducted in the long-duration microgravity environment on the International Space Station.

In a statement issued by NASA, the application of this new technology has resulted in an unprecedented reduction in the time required to charge a vehicle and has eliminated one of the key barriers to the worldwide adoption of electric vehicles.

Thus, if this innovation is adapted to electric cars, the problem of battery autonomy would disappear. The company claims that the process is capable of charging a car in five minutes through an alternative cooling method, designing a charging cable that can supply 4.6 times more current than the fastest electric vehicle chargers currently on the market.

In addition, this module resembles an actual charging station, where the relevant pump, a tube with the same diameter as a real charging cable, the same instrumentation controls, along with the same flow rates and temperatures are included.

The National Aeronautics and Space Administration (NASA) has always been at the forefront of innovations to surprise the world with new technologies and discoveries that mark human history.

The testing and production of electric vehicles, currently booming, has also encompassed the recent research of scientists belonging to the organization. In 2021, they announced tests of an electric flying cab, an all-electric vertical take-off and landing (eVTOL) aircraft.

On this occasion, NASA revealed that it is working together with Electra.aero, a company specialized in electric aeronautical technologies, to manufacture electrified ultra-short take-off and landing (eSTOL) aircraft, with the aim of boosting aerial mobility with strict sustainability standards.

Specifically, Electra is working on a sophisticated electric take-off and landing structure that will enable the vehicle to hover or touch down in a distance of just 45 meters. This involves enormous technical efforts, which will be targets to be overcome by current aerodynamic technology.

Technology Details and the Role of NASA

The system Electra is working on is called “blown lift” aerodynamic technologies. Effective blown-lift aircraft concepts require all possible tools for their technical refinement; elements such as computational fluid dynamics (CFD), wind tunnel models and real test aircraft will be used extensively for this purpose.

For the company, this is a challenge never before seen in aeronautical engineering, since not even the best CFD-based distributed electric propulsion and blow lift models can obtain data on these types of technical configurations.

Electra eSTOL Aircraft

While it is true that Electra handles state-of-the-art technologies, there is a need for much faster, more powerful and reliable computers with which to perform the engineering design tasks themselves. To this end, NASA has launched this economic investment, the exact figures of which are unknown, but they have admitted that it solves all the problems and lack of funding that they suffered until now.

It is estimated that the tests of these innovative flying vehicles will begin this year. An aircraft will be used to demonstrate the hybrid eSTOL technology on a large scale.

This prototype will be able to carry a maximum of two people on its journey. It will presumably take off and land at distances of less than 45 meters. This model will use a 150 kW hybrid-electric turbogenerator to drive a total of 8 electric motors and regenerate electricity from the battery, the capacity of which is not yet known.

However, the first completed and commercially available model will be launched on the market in 2026.

Worldwide, we are seeing initiatives of flying cars or vehicles powered by electric energy and hydrogen, designed to take the skies. NASA, a world leader on innovations that have astonished mankind, is testing an electric cab with Joby Aviation.

The U.S. space agency is trying to close the project with three years of development. The vehicle is an all-electric vertical take-off and landing (eVTOL) aircraft. It is powered by six rotors and claims to be quiet enough to not cause a nuisance over urban areas.

It has the capacity to carry four passengers at speeds of up to 350 kilometers per hour.

Features

The vehicle has a flight range of more than 150 miles, a little more than 200 kilometers, a distance covered in one hour and 17 minutes. 

It is expected that in the future, eVTOL airplanes may be used as air cabs for people in cities and surrounding areas, in order to have another mode of transportation to move people and goods, said the National Aeronautics and Space Agency on a press release.

Joe Ben Bevirt, founder and CEO of Joby Aviation noted that NASA’s National AAM (Advanced Air Mobility) Campaign is essential to furthering scientific understanding and public acceptance of eVTOL aircraft.

During testing, engineers used a mobile acoustics facility comprised of more than 50 microphones to accurately measure noise emissions across different phases of flight.

“From day one, we have prioritized building an aircraft that not only has an extremely low noise profile, but one that blends seamlessly with the natural environment,” added Bevirt. “We have always believed that a minimal acoustic footprint is key for making aviation a convenient part of everyday movement while not compromising life quality,” he said.

For his part, Davis Hackenberg, NASA’s AAM mission integration manager explained that the National Campaign Development Test is an important, strategic step in the agency’s goals to accelerate the AAM industry’s timeline.

“These test scenarios will help inform the gaps in the current standards to benefit the industry’s progress on integrating AAM vehicles into aerospace,” he added.

Joby expects the U.S. Federal Aviation Administration to give them flight certification by 2023, and is confident that it will be able to begin service the following year.

Humanity has just experienced another exciting chapter of technology and, specifically, in the missions that NASA carries out in space. This time it is “Ingenuity”, a drone that flew over Tuesday and sent shocking images of the red planet.

The device is composed of a total mass of 1.8 kg and 273 g in batteries according to data provided by the space mission. It also has a height of 0.8 m and is capable of working between 1900 and 2800 revolutions per minute.

NASA details that one of the main characteristics of the Ingenuity is the aforementioned dimensions, since the main challenge for the engineers was to make it as light as possible.

The scientists assured that the objective of the new flying object is only limited to experimental work, far from Perseverance, which is intended to search for signs of life beyond the earth.

 The Ingenuity made a series of flights with an average duration of 40 seconds and rose 3 meters in the air, “floated, turned and landed safely,” explained NASA, noting that this was the first controlled and powered flight on another planet.

Impressions at NASA

“It sounds simple, but there are many unknowns regarding how to fly a helicopter on Mars,” Ingenuity’s chief pilot, Havard Grip, Ingenuity’s chief pilot at NASA’s Jet Propulsion Laboratory.

“Every image we get of the helicopter on Mars is special to me: After all, this has never been done before,” wrote MiMi Aung, project manager for the Mars Ingenuity helicopter, of the helicopter upgrade. 

“While it’s up to others to decide the image’s historical significance of this moment, when I first saw it, I immediately thought of the picture Buzz Aldrin took of his boot print on the lunar surface. That iconic image from Apollo 11 said ‘we walked on the Moon’” he wrote.  “Ours says ‘we fly in another world.'”

 “So far, the engineering telemetry that we have received and analyzed tells us that the flight met expectations and that our previous computer model was accurate,” said Bob Balaram, chief engineer for the Ingenuity Mars Helicopter at the Propulsion Laboratory. NASA jet in Southern California, in a statement.

The space missions agency indicated that the medium-term goal is to enable other advanced robotic flying vehicles that could be part of future robotic and human missions to Mars.

Innovation in means of transport of all kinds continues to be talked about and, in this case, it is NASA that comes up with an extremely ecological technology by developing bicycle tires that do not need to be inflated.

Startup “the SMART Tire Company” will launch METL tires on the market next year, originally developed and tested by NASA for future rover missions on Mars.

Nickel and titanium are important components of these “rubbers” because the material from which is made is a superelastic called NiTinol + and that represents the alloy of both.

In this sense, they explain that it is a kind of metal that reorganizes its molecular structure when bent, nevertheless returns to its original shape without problems, so they also clarify that, despite not using air, they never flatten. They are as elastic as rubber, but as strong as titanium, and are the first eco-friendly alternative to achieve a light and smooth ride.

“This SMART Tire was born out of the extreme challenges NASA faces on Mars, where there are no roads, temperatures can reach -200C and tire performance is mission-critical,” experts said.

MELTs can be used for road, sand, mountain and other types of surfaces, because they are covered in a poly-rubber material formulated for the tread, that allows a more durable grip and it adapts to any type of weather.

Likewise, by having a bicycle with these tires, a means of transport will be available to adapt to quite complicated surfaces, such as the Moon or Mars for NASA.
