That information is combined with multi-spectral images of fields taken by advanced camera systems from satellites and airplanes.
and solar cells to be developed for highly integrated electronic and optical circuits within a single atomic plane."
For the drone it works fine and the design lets the wing fly fast like a plane.
#NASA's drone is part chopper, part airplane Answer: NASA'S latest drone prototype, GL-10.
"During the flight tests we successfully transitioned from hover to wing-borne flight like a conventional airplane then back to hover again.
Planes and helicopters can be terribly expensive for collecting this overhead video and measurement data, though.
one of the world first supersonic civilian airplanes, which flew from 1976 to 2003 and became a watchword for travelling in style.
a European-designed aeroplane capable of cruising speeds up to eight times faster than sound (8, 500 km h or 5, 280 mph) taking passengers from Brussels to Sydney in 2 hours and 55 minutes.
At the AIAA Hypersonic Space Plane conference in Glasgow in Scotland in July, a paper submitted by Lapcat-II researchers said their early airliner tests suggested such a design would be greener than current aircraft,
One is a Mach 5 plane the Lapcat-A2 powered by a precooled air-turbo ramjet;
and a promising Esa-designed Mach 8 plane, also powered by a ramjet engine. A ramjet is an air-breathing jet, with no major moving parts.
Ramjets can move a plane very fast. But how do you power them? Fuel choice is important,
says Hideyuki Taguchi, leader of Jaxa hypersonic airplane research. Hunger for hydrogenbut, deriving hydrogen efficiently is one main factor for high operating costs.
sulphur oxides or soot like today subsonic airplanes, there is another issue. Water vapour produced by hydrogen combustion stays in the stratosphere for a long time
And Lockheed martin has a commercial plane, the N+2, that will travel at Mach 1. 7. There one problem with flying so fast,
and Boeing to design airplanes that break the sound barrier more quietlyanother problem is that of the uperboomwhich develops
when a supersonic airplane changes its speed, turns or manoeuvres. In a superboom the ground noise of a sonic boom is two
As the European hypersonic plane will fly higher, its ground shock waves will be spread out and produce a smaller shock wave.
and Boeing to design airplanes that break the sound barrier more quietly. From 2020 to 2025 it may be possible that airplanes could then exceed the sound barrier over populated land without causing a major disturbance.
In Europe, Steelant team tested their 300-seat design, albeit a 1: 120 scale model, at speeds of Mach 8 within a wind tunnel.
While the design consumes two times more fuel per second than a Mach 4 plane, it gets to the destination in roughly half the time so the fuel consumed overall during the trip is roughly the same.
When we have a lighter airplane, we have lower fuel consumption and smaller tanks, which makes the vehicle again smaller,
Airbus and Aerion aeroplane tests will start in 2019. The European A2 Mach 5 aeroplane may take another 20 years to complete.
The Esa Mach 8 aeroplane might become commercially sustainable sometime in the mid 21st Century.
The Concordes and Tupolevs that paved the way for supersonic air travel in the 1970s now gather dust in museums.
as we can easily install this system into a drone, airplane, or satellite to detect plant photosynthesis on a large scale to assess ecosystem health,
but in the air it flies more like an airplane. Future versions of the drone could be used for a variety of applications,
before demonstrating that it can also fly like a conventional airplane. Now, the researchers are examining ways to make the drone more aerodynamically efficient,
"We have demonstrated now an entirely new class of electromagnetic metamaterials that are fabricated from separate atomic planes of Van der waals materials,
which is used already for scanning by plane, satellite or tractor, has become a precise, noninvasive and more affordable tool to check how crops are doing.
