The World’s Fastest Brick-Laying Construction Robot

“A robotic truck equipped with a 105-ft (32-m) telescopic boom arm has just journeyed from Australia to Florida. Now the construction robot will get busy churning out up to 10 houses in a bid to become the employee of choice for building entire communities.

The truck and its accompanying brick-laying arm is known as the Hadrian X and has been developed by robotics company FBR, which first announced its prototype in 2015. That machine could complete a full-sized house in two days. Last year, FBR (which used to stand for Fastbrick Robotics), showed off the new Hadrian X which, at top speed, could stack 500 USA-format masonry blocks per hour.”

Balloon Company Sceye Heralds a New Layer of Human Exploration

“Stratospheric balloon company Sceye recently completed a feat that heralds the increased use of a new layer of the atmosphere for human exploration, the company told Axios exclusively.

Why it matters: The company’s helium-filled balloons can serve as an observation platform that occupies a niche between drones flying at lower altitudes and satellites orbiting above the planet.

This makes them attractive for Earth-observing applications, including climate-related monitoring and research.”

How the XB-1 Aircraft Went Supersonic Without a Sonic Boom

“When the experimental XB-1 aircraft broke the sound barrier three times during its first supersonic flight on 28 January, it did not produce a sonic boom audible from the ground…

the XB-1 took advantage of a physics phenomenon called the Mach cutoff. Because sound moves more slowly at higher altitudes, an aircraft breaching the sound barrier at those heights will produce a boom that cannot reach the ground – if the boom moves downward, the increasing speed of sound will deflect it, pushing its shock waves upward instead.”

Passenger Jet Prototype Breaks Speed of Sound

“A prototype of a passenger jet designed to succeed the supersonic Concorde broke the sound barrier for the first time on Tuesday above the Mojave Desert in California.

Why it matters: Exceeding Mach 1 speed — 770 miles per hour — is an important milestone in the quest by Boom Supersonic, a Denver-based startup, to resurrect high-speed air travel 22 years after the Concorde retired.”

XB-1 Passenger Plane 1 Step Away from Breaking the Sound Barrier

“The unofficial successor to Concorde is one step closer to reality after Boom Supersonic marked the 11th successful test flight of its XB-1 supersonic demonstrator aircraft.

On Jan. 10, the XB-1 completed a sustained flight at 728 mph (1,172 km/h) — equivalent to Mach 0.95, which is just shy of the speed of sound.

The test was conducted at a height of 29,481 feet (8,986 meters); while the aircraft flew at this speed in its 10th test, that test was at a much higher altitude and therefore a lower air pressure.

By flying so fast, so low in the latest test, the XB-1 achieved a record 383 knots equivalent airspeed — indicative of incredibly high dynamic air pressure. The aircraft will never experience such intense conditions again even when it finally breaks the sound barrier, as its in-service flights will take place at much higher altitudes where the air is thinner, company representatives said in a statement.

Putting the aircraft under this strain at transonic speed, just below the speed of sound, demonstrates the robust quality of its airframe and proves it will remain controllable at higher speeds.”
