It’s a bird, it’s a plane, it’s a new flying machine

1014MEM_Cover.inddBy the year 2154, humans will have severely depleted Earth’s natural resources.

This isn’t a prognostication or a personal political proclamation, it’s the premise on which the hugely successful 2009 film Avatar is based.

If the notion of Earth’s depleted natural resources weren’t enough, the plot gets unimaginably more intriguing from there. Those who saw the movie know what I’m talking about, but even if you didn’t see it, you might remember watching some of the spectacular footage from the film in ads showing aerial battles waged in futuristic helicopters over the varied, extraterrestrial terrains. The film’s creative team was rewarded for its imagination and imagery by winning Oscars for best art direction, best cinematography, and best visual effects.

These images stirred the imagination. Blog posts following the movie’s release marveled at the mighty looking mechanical systems that lift vertically and whip around with power and might. Some bloggers speculated whether elements of these helicopters already existed and wondered whether such high-powered vehicles could ever be manufactured.

The U.S. Army wondered the same thing, but its concerns are, obviously, much more serious than those of bloggers or movie producers. Current military helicopters are based on designs of the 1970s and 1980s, while faster and durable civilian rotorcraft have been ushered by advances in engines and other technologies.

In 2008, the U.S. Department of Defense began defining the scope of a project to replace the legacy helicopter fleet with next generation vertical lift aircraft. The initiative, called Future Vertical Lift (FVL), represents a family of platforms across all of the U.S. defense departments. The DOD brass believes that some of the technology developed under FVL will also help civilian industry in the form of advances in rotating machinery and operating efficiencies.

Two years ago, the Army funded a program called Joint Multi-Role (JMR) Technology Demonstration “to inform future acquisition programs that fulfill the FVL initiative,” said retired Lt. Col. Dan Bailey at a keynote session a few weeks ago during ASME’s Design and Manufacturing Impact Forum. Bailey is the program director for JMR and FVL and, having logged more than 325 hours of combat duty in Apache and Black Hawk helicopters, certainly knows a thing or two about the topic. He said the goals of the program are air vehicle demonstration and mission systems architecture demonstration.

Around the same time as Bailey’s speech, the Army selected two industry teams to develop this new type of helicopter. The Bell unit of Textron Co. in partnership with Lockheed Martin Corp. represents one team; the other is a team of Boeing Co. and Sikorsky Aircraft Co. Analysts say that, by creating a competition, the Pentagon is testing a new way to develop and purchase weapon systems.

If development of these advanced aircraft ultimately gets the green light, we won’t have to wait until the Avatar year of 2154 before they’re flying around, but it won’t be before the mid-2030s either. By then, Earth’s natural resources won’t likely be depleted (this month’s power and energy articles provide some insight on that), but there’s no word yet from the DOD if the Avatar brain link project will have gotten the go-ahead.

    Similarly to One way link tip #5, this action brings you more visitors
    from your social web. A portion of these visitors may end up backlinking back to you.

    One way link tip #7: Track your own competitors’ hyperlinks

    Any inbound link tool can tell you who might be linking for your competition, yet very few
    of them sort these types of links by freshness.

    Cognitive SEO has a tool that will shows you the particular freshness of these links.
    Basically, it’ll show you who lately linked to your competitors.
    All you have to do is choose “Fresh Links” within its dashboard.

    clean links

    From this article you can see, the Intellectual SEO provides a list of
    probably the most recently found backlinks.

    After that you can take that list and manually hit up all of those websites with an e-mail like this one:

    Hello [insert their name],

    I was just reading your site post upon [insert the write-up title and link to it] plus noticed that a person didn’t url to [insert your URL].
    I’m not sure if you are acquainted with it, however it can teach your
    readers regarding [insert the value their own readers can get].

    For each 100 this kind of emails you send out,
    you’ll typically produce 7 in order to 10 links.
    It’s not a lot of links, but it adds up.
    Bottom line

    Creating a good product or service or writing excellent content
    does not guarantee that individuals will link to you.
    If you need to build hyperlinks and, moreover, generate visitors, you have to be positive.

    If you check the techniques I mentioned previously, you’ll notice that in addition to obtaining more inbound links (and
    eventually more lookup traffic), you’ll also see an increase in your
    referral traffic.

    Exactly what are some other positive ways to gain backlinks?

    G. S. If you need building organic links that will boost your traffic go here.

    Woah! I’m really enjoying the template/theme of
    this site. It’s simple, yet effective. A lot of times it’s very difficult to get that “perfect balance” between usability and visual appeal.
    I must say you have done a great job with this.
    Also, the blog loads super fast for me on Opera. Outstanding Blog!
