3D Printers Open Up New Options in Aviation

3D Printers Open Up New Options in Aviation

by Mike Hoffman on June 20, 2013

PARIS — Add aircraft engines to the growing list of complex parts that companies are now depending on 3D printers to produce.
GE Aviation will produce the cobalt-chromium fuel nozzles in CFM International's Leap engine with a 3D Printer. The company will use a MarketBot printer to "grow" the part rather than assemble it using the previously required 18 components.
3D printing — or what some call additive manufacturing — continues to grow in the defense market. GE Aviation brought a demonstration model of a 3D printer here to the Paris Air Show to give attendees a first hand look at how easy it operates.
The company plans to make at least a $3.5 billion investment into 3-D printing to produce a host of parts at rates officials with the company claim will be 20 times faster. Eliminating multiple components from the parts also lightens the equipment. GE Aviation officials said the fuel nozzle built by the 3D printer will be 25 percent lighter.
The U.S. military has already seen some of the advantages that 3D printing can bring to the battlefield. The U.S. Army's Rapid Equipping Force has deployed a team of engineers with a 3D printer to Afghanistan. There, the team has been able to build parts after soldiers have provided direct requests.
Unit commanders have lauded the REF team for the ability to quickly build parts to equipment they need with the use of the 3D printer.
Many mistake 3D printing and its limits. Often, some people will assume a 3D printer can only produce pieces out of plastic. This is wrong.
GE Aviation, for example, said the MarketBot printer can produce parts out of titanium, aluminum, steel and inconel. The lasers built into the printers are hot enough to melt the material and use it to build parts, a GE Aviation official said.
Even using the metallic material, the 3D printer still looks and appears to operate much the standard ink printers seen in offices around the world.

Parachute oscillation, off heading.

Posted: 24 Jun 2013 03:22 PM PDT

"Since the beginning of parachute making, it was seen that if no spill hole was present in a parachute,it would pitch violently back and forth. In this experiment, the constructed parachute was tested both with and without a spill hole.As was expected, as soon as the spill hole was covered, the oscillations of the parachute were greatly exaggerated. This occurs because excess air pressure builds up at the top of the inside of the parachute and tries to escape out of either side of the bottom of the parachute. This causes it to tip to one side, and as the parachute and payload tip back in the other side of its oscillation, the air pressure escapes out of the other side: therefore reinforcing the oscillations and not allowing it to be damped out as easily. When the spill hole was covered, this was seen immediately. Almost all of the drops without the spill hole simply ended up swinging into the floor directly below the drop floor due to its more pronounced oscillations, which never happened with the spill hole. This phenomena which is seen on full-sized parachutes, was validated by our small-scale testing."

so on Pc if your using 46,48, go and throw to 1sec. upward toss, the oscillations should be minimal or no factor (not counting the other factor). pass 1 sec. or more you begin to notice oscillations more. time for vent maybe. if you have 50,52PC differently need vent( because of inversion of the pc ).

oscillations on 42 and smaller PC.factor how you toss,wind angle,the material.
solid object.

you toss your pc to your right side(have you try to toss straight up ? hard),
now if the wind angle is from right to left the wind cross or side will help the center your Pc over your back keeping oscillations and off center opening to minimum.

if the wind angle is from left to right cross or side will cause the Pc to move away from you than as increase in drag cause to whip back to left causing oscillations and or spinning of the Pc causing off heading and or line twist.

If oscillation is keep to minimum there is no problem, if using ZP think abut having vent.

Using larks head knot on Pc you can'tnever get it to attach straight, Use a softlink or some thing other to attach the bridle to pc,


No human is perfect so check you pc forsquareness make 12 pie out of the pc and take a measurements makesure vent,cap, and handle is centered to the pc.


The most important is how you pack,keeping line evenly, when you make figure eight lay the line on top of another with out twisting the line.
Keep your body symmetrical.
Watch out for cross wind.
At pull time pull do not hold on to the pc too long or you will get line twist,
I did that a yellow ocean had 160 whit2 and ¾ twist and my neck was pin down, I only can look down trying to grab the riser twice to no avail, I bicycle kick out and riser turn away from the cliff.
A person with phd and ten book to his credit dos not means he is right all the time or some of the time they are all thesis, just like my thought take as you may.

Posted: 24 Jun 2013 06:00 AM PDT

Here’s Skydive Spaceland’s recipe for an awesomesauce: 3 cups of big-way head down camp, 2 cups of shredding with David Schwartz, 10 lbs of badass swooping by Kritter Weiss, and a dash of Trent Alkek (not enough to piss you off, just enough to spice things up). Mix in bowl and place in bread pan. [...]
