Hyundai’s new Supernal to lead charge into AAM future

South Korean transportation giant Hyundai has announced the creation of an advanced air mobility (AAM) company, Supernal LLC. The company will pursue the development of next-generation passenger electric vertical takeoff and landing (eVTOL) vehicles, and aims to conduct its first commercial flight in 2028.

“We’re developing a commercially viable Advanced Air Mobility product from the start, designing and manufacturing our vehicle to the highest safety, noise, efficiency, and affordability standards,” said Ben Diachun, Supernal’s chief technology officer. “Our growing team, which includes veterans of aerospace, automotive, and other deep-tech industries, is engineering sustainable vehicles that have the potential to evolve how we live, work, and play.”

Rolls-Royce secures £450m for mini nuclear reactors venture

Rolls-Royce will move ahead with a multibillion pound plan to roll out a new breed of mini nuclear reactors after securing more than £450m from the government and investors.

The engineering firm will set up a venture focused on developing small modular nuclear reactors, or SMRs, in partnership with investors BNF Resources and the US generator Exelon Generation with a joint investment of £195m to fund the plans over the next three years.

Astronomers Want to Build an $11BN Telescope That Would Outclass Hubble

The proposed telescope would be powerful enough to detect distant planets 10 billion times fainter than their hosting star.

Astronomers have proposed a telescope that would far exceed the capabilities of Hubble.

The National Academies of Sciences, Engineering, and Medicine just released its Decadal Survey on Astronomy and Astrophysics, also known as Astro 2020. The report outlines plans for the next decade of investment in astronomical equipment and projects in the U.S.

One of the real standout recommendations in the survey, DigitalTrends reports, is for a “Great Observatory” designed to replace the ailing Hubble Space Telescope, which encountered several technical problems this year due to its decades-old hardware.

NASA solar probe bombarded

The Parker Solar Probe is an engineering marvel, designed by NASA to “touch the sun” and reveal some of the star’s most closely guarded secrets. The scorch-proof craft, launched by NASA in August 2,018 has been slowly sidling up to our solar system’s blazing inferno for the past three years, studying its magnetic fields and particle physics along the way. It’s been a successful journey, and the probe has been racking up speed records. In 2,020 it became the fastest human-made object ever built.

But Parker is learning a lesson about the consequences of its great speed: constant bombardment by space dust.

Non-toxic technology extracts more gold from ore

Gold is one of the world’s most popular metals. Malleable, conductive and non-corrosive, it’s used in jewelry, electronics, and even space exploration. But traditional gold production typically involves a famous toxin, cyanide, which has been banned for industrial use in several countries.

The wait for a scalable non-toxic alternative may now be over as a research team from Aalto University in Finland has successfully replaced cyanide in a key part of gold extraction from ore. The results are published in Chemical Engineering.

Study shows new chloride-based process recovers 84% of gold compared to the 64% recovered with traditional methods.

NASA Lucy Spacecraft Update: Instruments Powering On and Working Normally

The Lucy spacecraft continues to operate in cruise mode – the standard mode for outbound orbit. The team has begun turning on instruments. L’TES and L’Ralph have been powered on and are working normally. Turning on L’LORRI is scheduled for November 8 2021. Other than the solar array, all subsystems continue to work normally.

The joint Anomaly Response Team has been studying the array using an engineering model. Initial tests indicate that the lanyard that pulls out the solar array may not have completed the process successfully; however, it is still uncertain what caused this condition. The team is conducting more tests to determine if this is indeed the case, and what the root cause might be.

An attempt to characterize the array deployment by attempting to move it would occur no earlier than November 16.

Ventilation matters: Engineering airflow to avoid spreading COVID-19

As we approach two full years of the COVID-19 pandemic, we now know it spreads primarily through airborne transmission. The virus rides inside tiny microscopic droplets or aerosol ejected from our mouths when we speak, shout, sing, cough, or sneeze. It then floats within the air, where it can be inhaled by and transmitted.

This inspired researchers in India to explore how we can better understand and engineer airflow to mitigate the transmission of COVID-19. To do this, they used their knowledge of airflow around aircraft and engines to tailor the airflow within indoor spaces.

In Physics of Fluids, they report computer simulations of airflow within a public washroom showing infectious aerosols in can linger up to 10 times longer than the rest of the room. These dead zones of trapped air are frequently found in corners of a room or around furniture.

A Colorado Firm Claims It Can Triple the Power of Electric Engines

The founding team at H3X have a compelling origin story. The three friends — Jason Sylvestre, Max Liben, and Eric Maciolek — formed a bond as they participarted in an engineering course regarding electric vehicles.

After their careers led them in separate directions, with each finding work in the tech and auto industries, a Department of Energy grant brought them back together to ponder how they could improve electric motors.

Their first-principles mindset and efforts have borne fruit in the form of a new electric motor that can potentially power large commercial flights.
