Mothballed B-52 gets a second chance

Seven years after it was sent to the U.S. Air Force’s famed “boneyard” at Davis-Monthan Air Force Base in Arizona, B-52H “Ghost Rider” has been reborn.

“It’s the first time we’ve ever brought any of the B-52s out of the boneyard,” said Col. Keith Schultz, a 6,500-hour veteran of B-52s who has flown many of the aging birds to that final roost but savored Friday’s flight resurrecting one to new life at Barksdale Air Force Base.

The flight to Barksdale was just under three hours but was unusual in several respects.

Schultz, commander of the Air Force Reserve’s 307th Operations Group at Barksdale, had the minimum crew allowed for the flight here. With him were just a copilot, Lt. Col. Darrell “Tim”

3-D Manufacturing Comes of Age for Airplanes

The other night, I saw a video reportone of several, actuallyabout how some government agency was lit up because it’s beginning to look like 3-D printing will be capable of making parts for firearms. In passing, it mentioned that complex airplane parts would soon be producible by 3-D technology. Yeah, I thought, when pigs fly.

Living in a fast-paced industrial society, you should never think such a thing, much less say it forsure enough, the airplane parts are happening already. Actually, they’re really aerospace parts for satellites and the preferred description of the technology is additive manufacturing. I’ve been hearing this term more and more; heard it a couple of months ago when I visited Lycoming. They’re not doing engine parts yet, but I suspect fast prototyping and non-structural parts aren’t too far in the future.

A company called Sratosys Direct Manufacturingformerly RedEyecontacted us a while ago to report that it made a batch of antenna arrays for a NASA satellite called FORMOSAT-7, a weather satellite system. It’s not the first time additive manufacturing parts have been to space, but it is the first time they’ve been used in a structural function

FAA proposes rules for drones

FAA Drones

WASHINGTON (AP) — Drone on, the government says.

Just not through the night sky. Or close to an airport. Or out of the operator’s sight. And probably not winging its way with a pizza or package, any time soon.

Long-anticipated rules proposed Sunday will open an era in which small (under 55 pounds) commercial unmanned aircraft perform routine tasks — crop monitoring, aerial photography, inspections of bridges and cell towers, and much more. But not right away. Final rules are probably two to three years away.

PDF: Proposed rules for drones

And when they are in place, they may include a separate category with fewer restrictions for very small drones, likely to be defined as less than 4.4 pounds.

The Federal Aviation Administration released a variety of proposed requirements for commercial operators to meet, such as passing a knowledge test administered by the agency as well as a federal security check. The small drones could travel as fast as 100 mph, at altitudes of 500 feet or lower. Flights over people except those involved in the drone’s operation would be prohibited.

“We have tried to be flexible in writing these rules,” said FAA Administrator Michael Huerta.

Aircraft Rotation forces on takeoff. And how the vertical stabalizer works.

see this topic:

 

buckeye shows almost everything to get the angular acc

then with the equations of

 

 

a – your angular acceleration

 

//this is for linear velocity not angular

v = v + a*delta_t;

pos = pos + v*delta_t;

 

 

 but the equations are the same then you will end up with a vector which will be your angular ‘translation’ for each axis for each control surface.

 

and you are almost there

 

 

the thing is to attach forces that are acting (the rotational part) to the center of pressure of each control surface (elevators, wings) which for slow velocities will be in wing case 1/3 of chord , 1/2 wing span, and mean chord,

 

lets assume Y is your up vector then according to that:

 

geom.gif

 

 

 

 

X = span/2 Y = mean choord y val in 1/3 from wing front,  Z = 1/3 of chord from front.

 

the math behind rotation for model itself (when you have your angles) is quite complicated thing. and i wont provide code for it. Alli can say its a rotation aroundrotated local axis.

YOu could use quaterions for that or single sin cos approach and build a rotation matrix.

 

 

I dont want to “hack” one of the four fources, i just want to add some “downforce” on the stabalizer that creates and “upforce” on the nose.

 

since wing center of pressure is not situated in the geometric center of the whole aircraft (not in the axis) it will rotate the plane after lift is sufficient.

and ofc elevator deflection does that too.

Model aviation scene gains altitude in the Valley

On a February afternoon at The Arizona Model Aviators Superstition Airpark flying site in Usery Park, near Apache Junction, there were clear blue skies and an occasional soft breeze.  “This is a perfect day for flying,” said Jim Legg, member of the Arizona Model Aviators (AMA), which is a club whose mission is to make model aeronautics a reality for anyone who wishes to build or fly radio-controlled model airplanes and is sanctioned by The Academy of Model Aeronautics which is a national organization.

Legg said he first got involved with model aviation when he was a teenager in western New York,  “I started off flying the control line planes, then my first radio control was a single-channel   airplane,” Legg said. “Not too much success with that.”  Legg said there was not much support in western New York for aspiring model aviators, but when he moved to Arizona that all changed.   “When I moved out here, I found friends who helped me out with it,” he said.  “The model aviation scene is stronger out here. There are a lot more people involved with it, and AMA is a big club.”   As a result, Legg has been an avid model plane builder and aviator since 1996.

Legg has a variety of model airplanes ,most of which are gas powered, scaled down versions of actual WWII fighter planes, but he also has a couple scaled

How Industrial and Manufacturing Companies Monetize Data

Slide Show

How to Monetize Data in Five Steps

Consumer information dominates discussions about how to monetize data, but customer-facing organizations aren’t the only ones profiting from the sale of data. Industrial companies, manufacturers and other B2B organizations are also looking for ways to monetize sensor and machine data.

For instance, tire manufacturer Pirelli collects data on tire pressure, temperature and wear-and-tear on trucks using sensors in its tires. It now offers that data as an add-on service for fleet managers and insurers, InfoWorld reports.

It’s not always such a clear path to monetization, though. While data monetization ranked among the top trends in Deloitte Consulting’s “Analytics Trends 2015: A Below-the-Surface Look,” it was with a big caveat:

“There’s an emerging perception that the more data you have, the better. In fact, more data brings more challenges. Capturing, storing, and protecting data comes with real costs.”

John Lucker, Deloitte Consulting principal and global advanced analytics and modeling market leader, says companies often underestimate the complexities of monetizing data. As I explored Thursday, monetizing consumer data requires companies to ask tough questions about privacy, ethics and data ownership.

B2B organizations tend to focus on machine-generated data or data from embedded devices, which is a bit less cumbersome than consumer data. While that may make it less complex to monetize — and certainly less creepy, Lucker adds — that doesn’t mean it’s simple. Just collecting,

As FAA proposes new drone rules, how does the government treat model …

The Federal Aviation Administration has proposed a new set of rules for commercial drone use, saying the regulations on model airplanes would not change.

So, how does the FAA treat model airplanes, and is the average hobbyist following the rules?

The regulations are spelled out in Section 336 of the FAA Modernization and Reform Act of 2012, and clarified by the agency in a 2014 letter in response to numerous questions.

President Barack Obama signed a law that defines a model aircraft using the following criteria:

    • It is unmanned

    • It can fly for sustained periods in the atmosphere

    • It stays within eyesight of the operator

    • It is operated for recreational purposes

    • Humans cannot directly intervene in its operation from within the aircraft or on it

The eyesight rule states that you must use your own natural vision (although corrective lenses are allowed) and not night-vision goggles, binoculars or other unnatural aids. This does not mean that you can’t use a spotter to help you look for obstacles or other aircraft, but that person’s line of sight does not add to your own.

That same law bans the FAA from making rules about model aircraft that meet the following criteria:

    • The aircraft is flown strictly for hobby or recreational use;

    • The aircraft is operated in accordance with a community-based set of safety guidelines and within the programming of a nationwide community-based organization;
