and cools in response to the outside air temperature it expands and contracts causing the bellows to do the same.
That means any slight shift in an office building s air conditioning or the natural outside air temperature during the course of a day would be more than enough to activate the chemical in the bellows.
The first step would be funding to update the Boeing/North american Aviation studies done in the 1970s.

Collars with GPS, RFID and biometrics can automatically identify and relay vital information about the livestock in real time.
Building on existing geolocation technologies, future swath control could save on seed, minerals, fertilizer and herbicides by reducing overlapping inputs.

and customize unmanned aerial vehicles (UAVS) for multiple applications. Today, hundreds of companies worldwide are making drones for infrastructure inspection, crop-and livestock-monitoring,
Now Airware, founded by MIT alumnus Jonathan Downey 6, has developed a platform hardware, software, and cloud services that lets manufacturers pick
The key component is the startup Linux-based autopilot device, a small red box that is installed into all of a client drones. his is responsible for flying the vehicle in a safe, reliable manner,
and display that info to a user, says Downey, Airware CEO, who researched and built drones throughout his time at MIT.
Airware then pushes all data to the cloud, where it aggregated and analyzed, and available to designated users.
Clients have trialed Airware platform over the past year including researchers at MIT, who are demonstrating delivery of vaccines in Africa.
Another UAV maker, Cyber Technology in Australia, is using the platform for drones responding to car crashes and other disasters,
Airware plans to launch the platform for general adoption later this year, viewing companies that monitor crops
A company from scratch Airware roots date to 2005, when Downey, who studied electrical engineering and computer science, organized an MIT student team including Airware chief technology officer, Buddy Michini 7, SM 9,
Phd 3 to build drones for an intercollegiate competition. At the time, drones were used primarily for military surveillance,
But their advisor, Jonathan How, a professor of aeronautics and astronautics who directs of the Aerospace Controls Laboratory,
A five-year stretch at Boeing as an engineer for the U s. military A160 Hummingbird UAV and as a commercial pilot put Downey in contact with drone manufacturers, who,
were still using black boxes or open-source designs. hey were basically facing the same challenges we faced as undergrads at MIT,
Thus Airware was born in 2010 first run only by Downey, then with Michini and a team of Boeing engineers to make a military-grade lack boxsystem,
but whose capabilities could be tweaked and extended. Early prototypes were trialed by How group at MIT,
before Airware entered two California incubators, Lemnos Labs and Y-Combinator, in 2013. Since then, theye raised $40 million from investors and expanded their team from five to more than 50 employees. he last 18 months has been a rapid rise,
Not much of the early MIT drone designs made it into the final Airware platform. ut building that early drone at MIT

Additionally, it could help the Federal aviation administration (FAA) better assess the reliability of drones; Congress recently tasked the agency with compiling UAV rules and regulations by 2015.
This could also help promote commercial drone use in the United states, which lags behind other countries around the world, primarily in Europe,
Using GPS, this device can specifically locate and report the location of a leak in a pipe.

"All four engines on the left wing are given the same command, "said Zach Johns, the prototype's main pilot."
"Successful flight tests have not only demonstrated its hovering capabilities during its vertical takeoff--the way a helicopter does
"We did lose some of the early prototypes to'hard landings'as we learned how to configure the flight control system.
It could be used for small package delivery or vertical takeoff and landing, long endurance surveillance for agriculture, mapping and other applications."
"An additional strength is the UAV's lack of noise inflight, said Frederiks.""It's pretty quiet.
#Airware Launches Its Commercial Drone Operating system Drones could save businesses big money by doing dull, dirty,
Airware is out to change that with today launch of its Aerial Information Platform. Commercial businesses can now license Airware Flight Core autopilot technology,
Ground Control Station for dispatching drones, and its cloud platform for customizing missions and collecting data.
the four year-old Airware is perhaps Silicon valley premier drone startup. Airware integrated hardware software, and cloud system lets enterprises customize drones to check on gas pipelines,
survey farm land, inspect cell towers, patrol property, or do search & rescue, Now wel see just how many businesses will pay a monthly subscription for Airware to power their drones for industrial inspections, agriculture management, anti-poaching, and more.
Consumer drone makers are growing fast as quadcopters become the hot new toy for kids and adults alike.
Airware bussed investors, customers, and a handful of reporters from San francisco to an isolated farm in Petaluma, where the startup showed off its platform with a variety of drones built for different use cases.
Following a brief introduction by Airware CEO Jonathan Downey, CTO Buddy Michini demonstrated Airware core technologies:
the Flight Core autopilot system, which provides the brains to each drone that Airware powers,
the Ground Control Station that lets a single user operate a fleet of drones from a Windows laptop or tablet,
Airware can handle the whole process. The goal is to reduce the drone piloting expertise needed to get complicated missions flown.
Drone operators just set up the standard Airware control system enhance it with cloud widgets to customize their drone to the day use case,
Operators can just trace a flight path on a map instead of driving the drone in real-time.
and dig sites using flight plans generated Airware Ground Control Station. Users simply draw out a geofence for the drone to stay within
After several similar demos, Drone America CEO Mike Richards spoke about using his company larger drones with Airware software for missions outside of traditional industrial uses.
During this time, Michini explained Airware plug-in system, which lets customers create widgets for the Ground Control Station in the C# programming language.
These widgets are actually the main reason Airware is sticking with Windows for its tablet app.
which will provide a full-on Linux computer for developers to work with in addition to the standard Flight Core autopilot and Ground Control Station integration.
When it rolls out to select Airware partners this summer, this new system will let customers take advantage of more advanced sensor
Airware can roll out new products like App Core without having to find new companies to sell to or upsell its current customers.
Airware costs $2500 per drone per year. But the company doesn have to race to revenue just yet.
Now his company Airware is going to teach them to do our bidding, and even save some lives g
So said Joelle Cornet-Templet, a chief stewardess for Air france, about Concorde: one of the world first supersonic civilian airplanes,
compared to around 22 hours on a Boeing 747. Concorde was the best-known member of an exclusive club of two;
the only other civilian airliner able to break the speed of sound was the Soviet union Tupolev tu-144,
which flew until 1999. A variant of the Tupolev was used in experiments by Nasa, and American and Russian aerospace industries, in a joint research program after the end of the Cold war.
The end of the Concorde and Tupolev airliners left the supersonic market empty. But now, 12 years after the Concorde fleet last flew,
even faster airliners are taking shape in research facilities. One of those designs is by Lapcat-II,
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.
A similar concept powers the new missiles used by the Eurofighter Typhoon fighter plane, for instance. Ramjets can move a plane very fast.
Airbus has patented just a delta-wing Mach 4. 5 hypersonic design that could be used to create business jets.
Also, they are working with US-based start-up Aerion to make available a fleet of supersonic jets for wealthy clients.
And Lockheed martin has a commercial plane, the N+2, that will travel at Mach 1. 7. There one problem with flying so fast,
The retired Concorde produced a 135-decibel noise on the ground a lot more than the average Airbus. Quote:
Nasa is working with Lockheed martin 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
Nasa is working with Lockheed martin 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.
By 2030 the hypersonic aviation industry could employ over 500,000 people, and be worth 3. 5 billion euros (£2. 5 bn) a year,
according to research by Airbus and the Japan Aircraft Development Corporation. he estimated ticket price for Tokyo to Los angeles is the same as that of an existing first-class seat,
Airbus and Aerion aeroplane tests will start in 2019. The European A2 Mach 5 aeroplane may take another 20 years to complete.
The Concordes and Tupolevs that paved the way for supersonic air travel in the 1970s now gather dust in museums.

"It could be used for small package delivery or vertical takeoff and landing, and long-endurance surveillance for agriculture, mapping and other applications,"Bill Fredericks, an aerospace engineer at the Langley Research center, said in a statement."
"We did lose some of the early prototypes to'hard landings'as we learned how to configure the flight control system.
