Material testing procedures that regularly check for fissures in rail tracks or aircraft support structures also rely on ultrasound.
For example, an unpiloted air vehicle might change shape from one designed for a cruise mission to one designed for a dive.
this is accomplished by synchronizing the projector so that as the laser scans a particular plane, the camera accepts light only from that plane.

Now Airbus'Marco Prampolini and Yohann Coraboeuf have been granted a US patent for an"ultra-rapid air vehicle"designed to fly at 20 km (12.4 mi) higher than conventional aircraft and over four times the speed of sound twice the speed of Concorde.
According to Airbus, the craft is essentially a flying tanker with most of the fuselage made up of liquid oxygen and ecofriendly liquid hydrogen.
Forward of this is a passenger cabin for 24 people, with the cockpit in the bow.
It's also a very odd looking airplane with a gothic delta wing that gives it a strangely truncated look
and oxygen are burned to keep the aircraft properly trimmed. But what really sets the Airbus dsign apart is its suite of propulsion systems used to keep it aloft.
it would take off like a conventional plane using ordinary turbojet engines, but once in the air, an open door in the stern of the plane reveals a rocket motor.
When this fires, it sends the aircraft into a near vertical trajectory, accelerating it to supersonic speeds.
As the airplane approaches Mach one, the turbojets shut down and retract into the fuselage. On completion of the acceleration phase the plane is now flying at anywhere from Mach 4 to Mach 4. 5 at an altitude of 30,000 to 35,000 m (100,000 to 150
000 ft). The rocket motor shuts down and is concealed again as the aft door slides shut to reduce drag.
A ramjet now kicks in and the aircraft cruises along its flight path and can cover a range of 9, 000 km (5, 600 mi) in three hours the equivalent of Tokyo to Los angeles or Paris to San francisco. Meanwhile,
the wing fuselage design dissipates the sonic shock wave over 110 to 175 km (68 to 109 mi)
and angles it at 11 to 15 degrees so it doesn't reach the ground.
At the end of the journey split flaps reduce speed and the turbojets take over for approach and landing.
Metal-oxide nanosheets were arranged on a single plane using a magnetic field. The nanosheets were fixed then in place using a process called light-triggered in-situ vinyl polymerization
So when a researcher airplane made a wrong turn during a thunderstorm and flew straight into a mile-wide cloud,
NASA wanted to use them in supersonic aircraft. The U s. military hoped they could be used in a new fighter jet.
Already, today engines employ elaborate cooling mechanisms that divert air for cooling that otherwise would be used to power the plane.

#Taking aircraft manufacturing out of the oven Aerospace engineers at MIT have developed now a carbon nanotube (CNT) film that can heat
The group tested the film on a common carbon-fiber material used in aircraft components,
"Typically, if you're going to cook a fuselage for an Airbus a350 or Boeing 787, you've got about a four-story oven that's tens of millions of dollars in infrastructure that you don't need,
mainly for deicing airplane wings. The team recognized that in addition to their negligible weight, carbon nanotubes heat efficiently
In experiments, Wardle and his team integrated the film into airplane wings via conventional, oven-based curing methods,
In initial experiments, the researchers investigated the film's potential to fuse two types of aerospace-grade composite typically used in aircraft wings and fuselages.
"The team is working with industrial partners to find ways to scale up the technology to manufacture composites large enough to make airplane fuselages and wings."
"Gregory Odegard, a professor of computational mechanics at Michigan Technological University, says the group's carbon nanotube film may go toward improving the quality and efficiency of fabrication processes for large composites, such as wings on commercial aircraft.

an international team of astronomers has discovered jets of material ejected by still-forming young brown dwarfs,
and found that four of them have the type of jets emitted by more-massive stars during their formation.
The jets were detected by radio observations with the VLA. The scientists also observed the brown dwarfs with the Spitzer
and Herschel space telescopes to confirm their status as very young objects. his is the first time that such jets have been found coming from brown dwarfs at such an early stage of their formation,
In the early stages of star formation, jets of material are propelled outward from the poles of the disk.
No such jets mark planet formation, however. Previous evidence strongly suggested that brown dwarfs shared the same formation mechanism as their larger siblings
but detecting the telltale jets is an important confirmation. Based on this discovery, e conclude that the formation of brown dwarfs is scaled a-down version of the process that forms larger stars,

and researchers at MIT are developing shape-shifting materials that could make aircraft simpler and lighter potentially saving fuel.
They can be integrated into aircraft easily replacing the need for more complex hydraulic actuators motors and hinges.
You can find them in cars airplanes robots and medical implants. But their use has been limited in aircraft
because many can t handle the conditions planes are exposed to such as extreme temperature changes says Christophe Cros a technology program leader at Airbus. The MIT approach has a number of advantages Cros says.
First most shape-shifting materials don t use carbon composites which are common in aircraft because of their light weight and high strength.
And though others have worked on carbon composites that can respond to a specific stimulus such as heat Cros says in the new approach the carbon composites can be paired with a variety of shape-shifting materials that respond to different environmental triggers.
If researchers can figure out how to make the stuff in large quantities it could be used as a structural material for making planes and trucks as well as in battery electrodes.
but it could also work for larger applications like airplanes, decreasing the need for time-consuming and expensive deicing treatments.
