SpaceX wins Air Force manufacturing research contract for hypersonic vehicle thermal shields

Posted by in categories: military, space travel

The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate manufacturing techniques for heat shields that protect hypersonic vehicles in flight.


WASHINGTON — The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate advanced materials and manufacturing techniques for heat shields that protect hypersonic vehicles in flight.

Heat protection is a critical technology to shield hypersonic vehicles from the intense heat experienced when flying at more than five times the speed of sound.

Away From Silicon Valley, the Military Is the Ideal Customer

Posted by in categories: drones, military

The Defense Department is hungry for small drones that will track objects and fly into buildings, combat zones and other dangerous areas with little help from remote pilots. Self-piloting drones will become a key part of fighting and other military activities in the years to come, said Mike Brown, director of the Defense Innovation Unit, a Pentagon organization that aims to facilitate cooperation between the military and the tech industry.


While much has been made of tech’s unwillingness to work with the Pentagon, start-ups are still plumbing the industry’s decades-long ties to the military.

CNN exclusive: A solar panel in space is collecting energy that could one day be beamed to anywhere on Earth

Posted by in categories: military, solar power, space, sustainability

The unit has yet to actually send power directly back to Earth, but that technology has already been proven. If the project develops into huge kilometers-wide space solar antennae, it could beam microwaves that would then be converted into fuel-free electricity to any part of the planet at a moment’s notice.


Scientists working for the Pentagon have successfully tested a solar panel the size of a pizza box in space, designed as a prototype for a future system to send electricity from space back to any point on Earth.

The U.S. and China Are Annoying Each Other With a Ton of Warplanes

Posted by in categories: military, surveillance

Things are getting pretty heated in the South China Sea.


The United States and China are engaged in the first military back-and-forth of the new year, sending many ships and aircraft into the South China Sea over the past few days.

This latest round kicked off with the return of an American carrier battle group to the region, followed by an unprecedented flight of eight Chinese bombers into nearby Taiwan’s air defense identification zone (ADIZ). Both sides piled on more fighters, surveillance aircraft, and bombers, making this dance-off a considerable escalation over previous years.

Modified Laser Cutter Fabricates a Ready to Fly Drone

Posted by in categories: computing, drones, military

This bolt-on system creates a drone that can fly straight out of your fabricator.


It’s been very cool to watch 3D printers and laser cutters evolve into fairly common tools over the last decade-ish, finding useful niches across research, industry, and even with hobbyists at home. Capable as these fabricators are, they tend to be good at just one specific thing: making shapes out of polymer. Which is great! But we have all kinds of other techniques for making things that are even more useful, like by adding computers and actuators and stuff like that. You just can’t do that with your 3D printer or laser cutter, because it just does its one thing—which is too bad.

Grumman’s LongShot drone can search & destroy

Posted by in categories: drones, military, robotics/AI

Instead of firing missiles, planes may carry and launch unmanned drones that will be able to shoot their own missiles to search and destroy targets.


Aerospace giant Northrop Grumman is wasting no time in this competition.

Just two days after DARPA named it as one of three competitors for the LongShot contract, the company released an image of its concept for an air-launched unmanned aircraft system (UAS), Aviation Week reported.

US Navy Research Lab engineers 3D print functional lightweight cylindrical antenna arrays

Posted by in categories: 3D printing, military

Engineers at the US Navy Research Laboratory (NRL) have deployed a 3D printer to fabricate optimized antenna components that could be key to advancing the US Navy’s radar monitoring capabilities.

Utilizing 3D printing, the engineers were able to create cylindrical arrays at a lower cost and with reduced lead times compared to those incurred using conventional specialized equipment. The resulting parts also proved to be significantly lighter than previous iterations, potentially lending them new end-use navigational or defense applications.

“3D printing is a way to produce rapid prototypes and get through multiple design iterations very quickly, with minimal cost,” said NRL electrical engineer Anna Stumme. “The light weight of the printed parts also allows us to take technology to new applications, where the heavy weight of solid metal parts used to restrict us.”

Linus Tech Tips reviews SpaceX’s Starlink Internet Service [VIDEO]

Posted by in categories: energy, internet, military, satellites

😃


Canadian YouTuber Linus Sebastián reviewed SpaceX’s Starlink Internet on his Linus Tech Tips channel (video below). SpaceX currently operates approximately 1085 internet-beaming Starlink satellites in low Earth orbit that will be part of a constellation of over 4400 satellites designed to connect the planet to the world wide web. To connect to space-based internet Starlink customers use a dish antenna and Wi-Fi router device. The company says the dish antenna is more advanced than what is currently in-use aboard fighter jets. The dish features a phased-array antenna, capable of transmitting and receiving signal from all directions as the satellites move across the sky. This week SpaceX started to accept preorders of the service via Starlink.com.

Linus Tech Tips created a great review video in which he tests Starlink’s speed and also talks about important aspects of the Starlink constellation, including a brief discussion on how the network works. In the video, Linus unboxes the Starlink Kit that costs $499USD, it includes a dish antenna, mounting equipment, power supply, and Wi-Fi router/modem device. The Starlink broadband internet service has no data cap, priced at $99USD per month. Linus and his team install the dish outdoors on top of the roof and connect to the network. First, he used the service to play multiple 4K YouTube videos at once, with good results. He just noticed a small lag when trying to load YouTube thumbnails and comments as four high-definition videos played simultaneously. Then Linus ran an online speed test, Starlink provided him with internet download speed of around 138 megabits per second (Mbps) and latency of 27 milliseconds (ms).
