What is the Future of Aviation?

So I've picked up a new side job because that's just how I roll--Social Media Pathfinder for Powering Imagination, an organization dedicated to advancing and advocating for improving aviation technology. How, exactly, does one do that, and how can I help? I'm still working that out. For now, I'm going to take a little time with this blog to share what I'm reading.

How, Exactly, Do You Make Airplanes Better?
Human beings have been flying in heavier-than-air crafts ever since 1903. The basic forces at work in flying a plane are lift, drag, thrust, and gravity. Since very little can be done about gravity, inventors have worked on increasing lift, reducing drag, and increasing thrust. As aircraft have increased in their performance and utility, they have become more specialized, and each type of plane has its own performance needs...and that performance can always be improved.

Commercial Aviation
Powering Imagination's primary effort is to improve aircraft performance is commercial aviation--those big, winged aluminum tubes we see filling our airports. While I'd love to tell you that P.I. is looking for ways to improve in-flight comfort, they're more interested in how to make the planes' performance better in the following ways:
  • Quiet Flight: making aircraft engines quieter--in the air and on the ground. The last big advance on commercial airliners was the high-bypass turbofan. But the Environmental Protection Agency keeps raising the bar for noise pollution standards. Powering Imagination is looking to demonstrate a quieter electric aircraft over the Grand Canyon.

    In addition to the standard subsonic aircraft we see every day, there are folks who would like to make supersonic aircraft quieter--so quiet, in fact, that those Earth-rattling sonic booms practically disappear. And then, of course, there's Elon Musk, who wants to reinvent aviation as he's been reinventing rockets and automobiles. Musk believes it's feasible to build an electric supersonic aircraft that performs both vertical takeoff and landing.
  • Improved Fuel Efficiency and Emissions: One of Powering Imagination's founders is Erik Lindbergh, grandson of Charles A. and Anne Morrow Lindbergh. Among their early feats, to demonstrate the commercial viability of aviation, the Lindberghs flew a "Great Circle" route from the Pacific Northwest north over Siberia, then south over Japan to China. Their grandson is looking to refly that trip 85 years later, this time to demonstrate the effectiveness and efficiency of sustainable fuel technologies.

    While a lot of work is being done on cutting-edge, non-kerosene-fueled aircraft, the conventional power plant builders--Pratt & Whitney and General Electric--have their own programs to wring as much power for as little fuel as possible within the current state of the art.
There are challenges to any new technology. Electric aircraft capable of flying 200-300 passengers across the Atlantic are unlikely anytime soon. Right now solar-powered planes capable of long-distance travel, like Switzerland's Solar Impulse, have massive wingspans and carry only one person.

A friend who's more tech-savvy than I am called electric aircraft "a joke," adding, "There are certain unmanned surveillance aircraft where that feature would come in handy, but today those aircraft can only be launched and recovered in very calm weather. Despite huge wingspans, their payload capability is quite low."

So there is skepticism, to be sure. Biofuels are not the only answer, either, and they'll need a lot of federal support to prime the pump, so to speak, before they become commercially viable. Whether that can or should be done is a debate reasonable people can make. But still: we never used to need an excuse to advance the state of the art. Why not keep trying?

Potpourri CXXXVII

Here's the latest batch of foolishness...

Boeing flew a formation flight with its newest and oldest aircraft.




Israeli nanotechnology researchers claim to have developed an anti-icing surface.


Some good news for a change: Russia wants to work with the U.S. on space projects past 2020. I don’t think that means they’ll lower the price of Soyuz launches anytime soon, but the sentiment is nice.


The problem with Voyager 2 has been addressed: a bit was “flipped” through random radiation.


The FAA chief doesn’t like his agency being a “piƱata” for airlines’ schedule delays. Okay, fine. But if the FAA has been slow to upgrade our out-of-date air traffic control system and ATC delays are the primary cause of planes being stuck on the tarmac, shouldn’t FAA be a legitimate target for the stick?


A citizens group from Texas is visiting Capitol Hill to make a plea for the Constellation Program. Visits matter. So do well-written letters. If you want the U.S. to continue having a human space exploration program (as opposed to just sending humans to low-Earth orbit, which is not exploration), then your voice matters!


Steven Colbert visited Johnson Space Center recently. Nice to have at least one influential media personality digging space.

The inner workings of a 1950s ballistic computer. Cool!


A 1939 Popular Mechanics article describing a transcontinental airplane flight—all 15 hours of it. Yikes!


A Saudi woman beat up a member of the nation’s morality police. I admire her spirit, but don’t like to think about the ultimate outcome.


The Long Now Foundation is sponsoring a talk on fusion.


Food for thought: Science Warriors vs. Philosophers of Science.

From Walt Disney World: How to move a 120-ton Winnie the Pooh tree.

In case you hadn’t noticed, there’s something of a revolution going on in Thailand.

From Hu, for D2: two articles on training marine mammals for homeland security purposes: here and here. Cindy, Sandy, Seymour, and Clyde have been busy.


The White House blocked a Chicago chef’s tweets as he was being brought in to serve the President. Predictable. Organizations want to use social media when it’s to their advantage and suppress it when it doesn’t. Can’t have it both ways, guys. And really: what's the security risk on a chef?

From Jerry Pournelle: why don't more medical discoveries become cures? Would you believe government regulations have something to do with it? Would you be more likely to believe it if the story was from Newsweek?

Sabine has some interesting thoughts regarding the No Child Left Behind Act (a regular volleyball Doc and I bat back and forth during some of our daily bull sessions). I will have to reread the entry when I get some more time. I'm not sure if I'm qualified or knowledgable enough to argue for or against any of her points, but she posits a very important question. Paraphrased, she wants to know how failing school systems are supposed to clean themselves up when they're given no money or other resources to do so?

Late Addition from Kate Down Under: a Civil War hero of Gettysburg receives a posthumous Medal of Honor 147 years late. I've actually stood at the position where Alonzo Cushing's artillery battery was emplaced, and it was not exactly excellent ground, nor could it have been easy fighting with no long-range guns. Cushing's unit held Cemetary Ridge in the face of Pickett's Charge at close range. I don't know what would've been crazier: being one of the 13,000 men Pickett led in a dash across an open field or being one of the artillerymen forced to hold the line against 13,000 charging Confederates. The Civil War (called "The War Between the States" by some historians or "The War of Northern Aggression" by historians in my neighborhood) is the reason why American military doctrine has since emphasized minimizing casualties. Over 600,000 American lives were lost in that conflict.

That'll do for now. Off to attempt 8 hours of sleep. I know: craziness!

Potpourri LXII

Another action-packed round of surfing. I find this stuff so you don't have to.

The latest Futures Channel video on the Ares Projects has been released.

Interested in what the Augustine Human Spaceflight Panel is up to? Here ya go.

Okay, here's something useful for you Guinness-drinking space fans: drink a Guinness, and possibly win a flight on Virgin Galactic. Brilliant!

Ya know, I've tried to refrain from personal comments about President Obama because there's so much wrong with his policies already. But it's come to my attention--and apparently the Drudge Report, too--that the man doesn't smile a lot. And that he can even look quite mean when he sets his mind to it. I don't think this is a happy guy. But then I recall some of my liberal friends in college thinking that anyone with a positive attitude was obviously an idiot because the world was too grim for anybody to be in a good mood or have a positive attitude. My only answer to that is that I know the world is in a bad state. Optimism, a positive attitude, and a happy disposition takes a lot of work and more than a little leap of faith.

Lunar Reconnaissance Orbiter has started taking pictures of the lunar surface. One goal is to scan the Apollo landing sites.

In addition to jet planes, ballistic missiles, and other "wonder weapons," the Third Reich also appear to have built the first stealth bomber. Now recreating ballistic missiles at the time I sort of understand (Huntsville and the Apollo program owe much to the pardoning of Wernher von Braun). But why would anyone recreate a Nazi stealth bomber 60 years later?

Speaking of jets, some gratuitous pictures of American aircraft busting through Mach 1...and some pictures of shockwaves created by atomic bombs.

I am SO glad Obama has followed George W. Bush's diplomatic approach to North Korea. It's done SO much good. It's kept them from speaking hostilly to its neighbor South Korea and from enriching uranium...

And much to my surprise, Five Guys Burgers have been named the best burgers in Northeast Alabama. Now I love their freedom fries, don't misunderstand me--any food that turns the brown bag they're served in a darker brown just HAS to be filled with nutritional goodness--but their burgers have yet to wow me. My military buddies from my life as a highway helper referred to the oil on Five Guys' fries as "70-weight AvLube." We restricted ourselves, ideally, to one visit to Five Guys' per quarter (more realistically per month). Anyhow, congratulations to the chain. I still love their fries, and hope their burgers improve.

Potpourri XLV

Speculation continues on the if-and-when of nominating Charles Bolden as the next NASA Administrator.

There might be hope for reporters in the mainstream media (that's a conservative term for the "Big Three" networks plus the New York Times, Washington Post, Los Angeles Times, and other related liberal-leaning media outlets). If they can't stay employed or hawk their wares in paper-based products, they can always get a job being the official reporters for the Obama White House. They're already in the tank for/with him anyway. Of course, if the newspaper business continues to head down the drain, Obama might bail them out, in which case they'll be nationalized regardless.

Scott had some more sites for buying gold:

Scott is also insisting that I go see a DC-3 and some other older planes at the Moontown Airport east of Huntsville tomorrow. I just might. It's been a draining week, and I could use the break.

Marshall Space Flight Center has centralized all of their social media sites on one page.

Congressman Parker Griffin is saying that Iran's latest missile test is proof that we need to maintain a missile defense capability. Well, duhhhhh.

A fellow writer and NSS Policy Committee person, Marianne Dyson, has a hopeful blog regarding Obama's space policy.

Want to live in an airplane? I must confess, I had some designs around those lines when I was in high school. Anyhow, there's a site for those of us who dare to dream.

Bjorn Lomborg writes about how some companies are using the "green" movement as a way to merely cash in. Again, duhhhhh.

Alka-Seltzer City, dude! A town in Ohio is about to have carbon dioxide introduced into the briny water below their fair city, turning that water essentially into seltzer water in an effort to sequester carbon. Certainly there are more effective, less ridiculous ways to do this...? Jerry Pournelle also offers a link to some individuals who are fighting the practice. My buddy Scott calls environmentalists "watermelons: green [environmentalists] on the outside, red [communist] on the inside." Gotta wonder sometimes, don't you?

Science fiction writers are continuing to help in the War on Terrorism. Someone's got to, right?
