The US Air Force Is Adding Algorithms to Predict When Planes Will Break

The U.S. Air Force has started to use algorithms to predict when its aircraft will break, part of an effort to minimize the time and money they consume in the repair shop. The use of predictive analytics has been blazed by airlines, which monitor their fleets’ parts in an effort to replace broken components just before — and crucially, not after — they break.

“I believe it is a must-do for us,” said Gen. Ellen Pawlikowski, the head of Air Force Materiel Command, the arm of the Air Force that oversees the maintenance of its planes. She spoke Tuesday at a Defense Writers Group breakfast in Washington. “We see this as a huge benefit.”

If the Air Force could reduce the risk of unexpected breakage — and the attendant need to fly replacement parts and repair crews around the globe — it could reduce costs and boost mission effectiveness. It could also increase the usefulness of the current fleet by reducing the number of aircraft that need to be be held in reserve as backups.

It starts with gathering data, such as the temperature of engine parts or the stresses on the airframe.

“We are trying to leverage what we already get off of airplanes, as opposed to trying to go in and put instruments in places,” Pawlikowski said. “It turns out there’s quite a bit that’s there, but it may not be a direct measurement. In order to

James Urso

James (Jim) Urso, 84, beloved husband of Polly (Daboll) passed away peacefully at home Sunday, May 13, 2018. Jim was born January 13, 1934 in New Britain CT. He was the eldest son of the late Sebastiano and Maria Urso. Jim served in the US Navy aboard the USS Cadmus from 1956-1958. Jim had many interests and hobbies but none greater than fishing. He never missed opening day at the Salmon River with his son and brother. He was an avid boater, the captain of the Lord Jim out of Noank. Jim was an accomplished artist and his passion for the sea showed in his oil paintings. He was employed by the New Britain Herald of Herald Square in New Britain. He began his career in 1961 as a machinist in the composing room and as the newspaper evolved he ended his career in 1994 as a computer technician. Jim will be forever remembered for his love of Volkswagen beetles that he rebuilt and painted with the help of his son in law. Jim will be dearly missed by his family. He and his wife Polly shared 59 years together in Southington, Old Saybrook, Florida, and Canton. He leaves his son James Urso Jr and wife Lynne of Shrewsbury, MA and his daughter Charlene Plourde and husband Doug of Avon. His children will forever remember their time with him on forest marches, flying model airplanes and rockets, and racing slot cars. Jim shared his hobbies and passions with his most

Those Parachutes for Small Airplanes Really Do Save Lives

Ever since Boris Popov introduced his “ballistic recovery systems” (BRS) for small airplanes in 1980, skeptics have continued to question their value. Popov came up with the idea of a whole-airplane parachute after surviving the structural failure of his hang glider, and Cirrus Aircraft subsequently incorporated the safety feature in its SR20/SR22 models. On its website, BRS Aerospace claims 380 lives have been saved by the system, which deploys a parachute that gently returns a disabled aircraft to the ground.

Recently an independent academic study confirmed how effective the system is in saving lives. The analysis, written by researchers from Ohio’s Wright State University and published in the journal Aerospace Medicine and Human Performance, found a 13-fold decrease in the odds of a fatality when the Cirrus Airframe Parachute System (CAPS, developed with Popov’s company, BRS Aerospace) was deployed in an accident, versus when it was not.

Based on National Transportation Safety Board accident data from January 1, 2001 to December 31, 2016, which included 288 Cirrus accidents and 57 deployments, the findings “suggest that [ballistic parachute recovery systems] could play a significant role in the next major advance in improving [general aviation] accident survival,” according to the authors.

Despite its import, the research has received little attention. “The last time I checked, the paper has not been cited by anybody,” said Dean Olson, lead author of the study with grad students Mustafa Alaziz and Adrienne Stolfi.

Even Cirrus and Popov were unaware of the study.

“Wow, this is pretty neat,” said

Advice to the New NASA Administrator

On April 19, 2018, Jim Bridenstine was finally confirmed as the new NASA administer, taking over the agency after more than a year (arguably more than nine years) of leaderless drift. Now that the one-time Navy pilot and Oklahoma congressman has had a few weeks to settle into his office and see what is going on, I feel it is an opportune time to offer some advice. So here it is:

Dear Administrator Bridenstine;

Congratulations on your appointment. You have taken over an agency, parts of which—the space astronomy and planetary exploration programs—have been accomplishing world-historic feats that will be remembered for centuries, while other parts—most notably the human spaceflight program—have been spending tens of billions of dollars achieving nothing at all. The difference is that the astronomy and planetary exploration programs have chosen to spend their funds in an intelligent purpose-driven manner, while human spaceflight program has been allowed to operate purpose-free.

Hubble, Kepler, TESS, Webb, Opportunity, Spirit, Curiosity, and Cassini were built and flown for reasons. In contrast, the human spaceflight program proposes projects, and then tries to invent rationales. The former spends money in order to do things. The latter does things in order to spend money.

Let’s take the current proposal to build a lunar orbiting space station as an example. What purpose does it serve? Some say that it “might be useful” to support a lunar base, which is the administration’s nominal objective. But is it necessary?

Let me put it this way, since you are a pilot. Let’s say

Radical closed-wing aircraft design could see greener skies take flight

With nearly 1 billion passengers taking to European skies in 2016 and the numbers still increasing, the growth in European aviation has been staggering. The effect is that even as many other industries are reducing greenhouse gas emissions through efficiency and new technology, aviation’s are on the increase.

One person flying from London to New York and back generates roughly the same level of emissions as one year’s home heating for the average European. At the recent Transport Research Arena conference in Vienna, Austria, a high-level event covering all modes of European transport, Professor Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany, said avoiding air travel completely was the best option for protecting the environment.

But as Sergio Barbarino, chairman of the Alliance for Logistics Innovation through Collaboration in Europe (ALICE) responded, that’s an unlikely scenario. ‘We can’t just tell people they can’t take their holidays in the Canary Islands anymore,’ he said.

Air travel may be here to stay, but there’s no doubt that engineers need to find new ways to make it cleaner and greener. One idea is to radically redesign an aircraft’s wing so that it requires significantly less operational fuel, an approach that’s currently under development by a project called PARSIFAL.

‘This solution could completely change the air transport of the future’

Professor Aldo Frediani,  University of Pisa, Italy

Father of aerodynamics

For their design, the team sought inspiration from the renowned German aviation engineer Ludwig Prandtl, often considered the father of aerodynamics. In 1924,

Plane’s parachute not deployed before crash in Douglas County

DOUGLAS COUNTY – While the National Transportation Safety Board hasn’t learned exactly what caused a plane to crash Friday night in Douglas County, it said the aircraft had a built-in parachute that was never deployed.

The plane was a Cirrus SR22 and this specific make has a safety feature built into all of its airplanes.

It’s called Cirrus Airframe Parachute System, or CAPS, “the most significant safety innovation in over a half-century of general aviation,” according to Cirrus’ website.

“There is a rocket with a parachute attached to it in the back of the airplane behind the baggage area,” said Bob Stedman, owner of Independence Aviation. “It’s designed and manufactured into the aircraft. You buy a Cirrus, you get CAPS. It’s just part of it.”

Stedman has a lot of experience with Cirrus aircraft. He said in his business’ fleet, there are 12 airplanes and 11 of them are Cirrus.

“You pull the CAPS handle, the rocket fires off, it takes the parachute out of the back end of the airplane right behind the baggage bay,” Stedman said. “The parachute deploys in about six seconds and then it lowers the aircraft to the ground in a flat position.”

The system is designed to save lives and a study by the National Center for Biotechnology Information proves it has. The NCBI studied 268 accidents involving Cirrus planes. In 211 instances, the parachute wasn’t deployed and 82 of them were fatal. Of the 57 accidents where the

Israel using small remote-controlled airplanes to combat Gaza’s …

Israel is employing small remote-controlled airplanes to battle the phenomenon of incendiary kites in the Gaza Strip, Hadashot news reported Friday night.

The military is using the planes, armed with cutting knives on their wings, to cut the kites’ wires, thus preventing them from carrying their payload of firebombs over the border and sparking fires in Israel.

According to the report on Friday the tiny aircraft’s operators managed to down seven kites flown towards Israel.

For the past several weeks, Gazans have been regularly flying kites outfitted with containers of burning fuel, often including charcoal and bags of sugar to ensure a long, slow burn.

The kite tactic was introduced as part of the weekly “March of Return” demonstrations at the border fence, which began on March 30 and are due to continue through mid-May.

The kites have regularly sparked fires in Israeli fields, and the army has struggled to thwart the new weapon.
