2022-06-01 03:18:21 How do planes take off and land on aircraft carriers?

In the new Top Gun we will see Tom Cruise, or rather Captain Pete “Maverick” Mitchell, take off from an American super carrier, aboard a Boeing F / A-18 Super Hornet. But how does a nearly 3000 kg plane take off in few tens of meters of an aircraft carrier? The secret is contained in a mechanism called “catapult” for take-off and with a system of cables for fitting...

2022-05-19 20:52:49 New kind of solar cells generate electricity even at night - UNSW scientists have announced a breakthrough in the field of renewable energy. They have developed a new kind of solar cells that can produce electricity even at night.’

Known as ‘Night-time’ solar power, the technology generates electricity from heat radiated as infrared light, in the same way as the Earth cools by radiating into space at night. However, it generates a very small amount of energy, but scientists hope to improve the results in the future.

A semiconductor device called a thermoradiative diode, composed of materials found in night-vision goggles was used to generate power from infrared light emission. This is an unambiguous demonstration of electrical power from a thermoradiative diode... read more: https://www.aerospacengineering.net/new-kind-of-solar-cells-generate-electricity-even-at-night/ Open / Comment

2022-05-14 20:44:56 High-power microwave technology to use against drone threats
The Pentagon’s Joint Counter-Small Unmanned Aircraft Systems Office has finished tests of a high-power microwave technology called The Epirus system that has the capacity of disabling several drones at once, according to a report by Defense News published on Wednesday.This isn't the Pentagon's first demonstration of the technology. It conducted two more last year in the spring and fall. This most recent test took place during a whole week from April 4 to 22 at Yuma Proving Ground, Arizona...Read more: https://www.aerospacengineering.net/high-power-microwave-technology-to-use-against-drone-threats/ Open / Comment

2022-05-12 20:57:21 The First-Ever Image of The Black Hole at The Center of The Milky Way - Four and a half billion years ago, our pale blue dot was born in the rubble left over from the birth of a star. Since then, we’ve been locked in a cosmic dance; Earth whirls around the Sun; and the Sun whirls around the galactic center – the dark, mysterious heart of the Milky Way.

Contained in that dark heart, around which the entire galaxy revolves, is a supermassive black hole named Sagittarius A*, clocking in at roughly 4.3 million times the mass of the Sun. We’ve been able to infer its presence, and measure it, based on the movements of objects around it, but never had we seen the object itself.

That image at the top of the screen – looking like a glorious blurry orange donut – is the dust around and shadow of Sgr A* itself, seen by humanity for the very first time, thanks to the hard work of the Event Horizon Telescope collaboration...Read more: https://www.aerospacengineering.net/the-first-ever-image-of-the-black-hole-at-the-cent Open / Comment

2022-05-08 17:13:06 SpaceX, Humanity on the Mars before the end of the 2020s - In December 2021, Elon Musk predicted that humans will be on Mars within a decade. Now, SpaceX President and Chief Operating Officer Gwynne Shotwell told CNBC‘s Shepard Smith on Saturday that humanity will touch the ground on the Red Planet before the end of the 2020s. “I think it will be in this decade, yes. People on the moon, sooner,” Shotwell said... Read more: https://www.aerospacengineering.net/spacex-humanity-on-the-mars-before-the-end-of-the-2020s/ Open / Comment

2022-05-07 15:44:37 ‘Air Shield’ tech aims for virus protection on airplanes - Air travelers are returning to the skies and U.S. planes are now typically flying full and with many passengers not wearing masks — a worry for those most vulnerable to COVID-19 infection.

Pexco Aerospace, based in Union Gap in Central Washington, plans to offer a solution for airlines that could be ready to fly next year... Read more: https://www.aerospacengineering.net/air-shield-tech-aims-for-virus-protection-on-airplanes/ Open / Comment

2022-05-07 15:25:30 Lockheed Martin tests new hypersonic weapon concept - A Lockheed Martin hypersonic missile prototype flew at five times the speed of sound “for an extended period” during a recent successful technology test for the U.S. military.

The hypersonic weapons test, which was announced April 5 by the Defense Advanced Research Projects Agency (DARPA), marked the second flight for the Hypersonic Air-breathing Weapon Concept (HAWC) program following a September 2021 test by Raytheon Technologies, DARPA officials said in a statement...
