Osprey shortcomings?

January 11th, 2012

A few weeks ago, in one of my rants, I mentioned the fact that I thought the Osprey was a craft conceived by a crazy person. This article is about a patent for a new tilt wing to replace Osprey type aircraft. It is presented as a better idea, in light of the fact that the Osprey has no backup if one engine is fails (or more accurately, if it loses a rotor).

Osprey replacement article

These ideas make my head hurt.

You build airframes based on requirements (one would hope). But which requirement is a priority? How about survivability?

So you put many motors around a circular frame, like a bicycle wheel. You sling the payload underneath. Motors can pivot independently outwards slightly for forward thrust. Their rpm can be regulated. If you lose one or two. the remaining adjust their position on the wheel, to redistribute the load equally. This cannot be any more complicated than a tilt rotor, right?

I’m just saying…

Time to think

November 21st, 2011

Recently, I joined the ranks of the unemployed. I still own a small company, but my day job has finally ended. it is kind of a bummer and kind of a relief. When you work states away from your boss, you don’t get a farewell lunch or plaque. You get a mailing address for returning all your stuff.

I do have more time to think now. Lots of time to ponder my situation, the past, the future, and everything in between.

I hear many people give their opinion of the Wall Street protests. “They want a handout” is a common phrase. If student loans are too high, it doesn’t matter. The students are the ones who accepted them. They have a choice. I hear this over and over. But it skips over the real issues of tuition costs skyrocketing, back breaking loans, and the real possibility of no job at graduation. There are so many issues like this wrapped up in the protests: Tax system unfair – lobbyists have all the power – congress is ineffectual – education costs are out of control – wall street killed our economy, but it did not kill wall street. I could go on and on.

Man, many Americans are just not sympathetic. And if they get their news from FOX, they leave their brain at the door. I just don’t think it is as simple as that.

People in these protests are mad, because they have seen too much in terms of not being fair and a lack of transparency. They have seen their vote amount to nothing. The rich wall street elite have more of a vote. The situation is not fair, and this gets to the hart of the matter. If you can afford a lobbyist, you can buy votes. It’s just that simple. If you are rich, you are insulated, perhaps. But you should at least pay a share of the taxes. A fair share. Of course, we idolize those who beat the system. Well, we did…

If Saddam would have had effective lobbyists, we would be up to our ears in cheap oil. Same with Gadaffi. We’d be swimming in it. Global warming be be damned. But no, we had to go to war. Let’s get physical.

We certainly did not need to invade Iraq. If you still cling to this idea, get help. We had two no fly zones over Iraq, so dangerous we engaged and destroyed our own helicopters on several occasions as a result of mistaken identity. We had every clandestine agency of world wide capability in there looking everywhere. Yet Saddam was creating a delivery vehicle that would hit Europe? Really? So what. Ever hear of the Tokyo fire raids in WWII? The Dresden fire raids? We now have weapons that make these bonfires look like Boy Scouts learning to make fire. We could have gone down this road instead of an invasion.

We did not need to invade Afghanistan either. Make a statement there? Yes, definitely. Something insanely ugly. But we certainly did not need to stay. Now, as soon as we leave, Afghanistan will fold like a house of cards. You heard it here first.

Anyone anywhere who understands our political system, our love of money, our self absorbed character, and our self imposed image of grandeur understands the leverage and power of effective lobbyists.

Unfortunately, you and I cannot afford lobbyists. It is beyond interplanetary for us. And we are invisible to them.

“But who will do all the research and brief our representatives?”. Gosh, maybe they could do that themselves with a staff?

Our political friends in Congress get a pretty good pension for not too much time served. Also, a majority are millionaires. If you are not a millionaire when you enter the Congress, you are almost assured you will be by the time you leave. Inside deals, with information we are not privy to, are made by our representatives daily. Ouch. How about a crumb for the little people?

Or maybe just some intelligent legislation?

Air Force jet flies again…

October 16th, 2011

The Enquirer had a story on the Northwest Homecoming Parade today, featuring a photo of the Air Force’s recruiting tool, a self powered one man jet float. That jet brought back some memories.

20 years ago that same jet participated in a parade in Amelia, Ohio. My brother Jim and I were watching from his front yard as the jet slowly idled by, then disaster struck! The jet suddenly swerved to the left, out of control, right into my brothers driveway. We leaped into action. The impulse to just see how the jet was built was enough of a draw to get our attention. The problem was a link on the left wheel that had broken, and after rifling through Jim’s garage we found enough supplies to fix it on the spot. The jet was soon back in action and the parade was a success. We were glad to do our part to keep the Air Force flying.

Hey Circus Lady…

July 14th, 2011

When I was a little boy, I stayed with my Aunt Marcy in Amelia, Ohio. She had a great big family, a cool home and big yard that went into the woods behind the house. But she wasn’t around much. She had to work away from home, leaving early, and returning home very late. I never know exactly what she was doing working so hard. A few days ago, going through old albums of my Mom’s, I discovered what she was doing. She was apparently the original Horse Whisperer for the local circus.

Just look at the eyes on that stallion. I sure would like to know what mental messages she was sending that horse…

Memorial Day in the present

May 29th, 2011

Here we are at another Memorial Day. Pretty much everywhere you will see celebrations of gratitude. Churches will ask veterans to stand for a moment during the service. Parades will be packed with vehicles and veterans of previous conflicts.

I always think of the people who never made it home. Some of them were volunteers. Many were draftees fulfilling their obligation. A few were running from trouble. What they all had in common is that they all thought they would return home. These were young men and women who for the most part imagined their deployment would be a brief interlude in what would surely be a long life. Some believed in the cause of the time, while others just believed in service to the nation, or to go along with their friends and get their obligation over safely. We can all identify with them in some respect. They are all gone. They will not return home alive. Some will not return home at all.

Then I think of current events. I think of all the people deployed to our two fronts. I think about it too long, and I get irritated.

Our nation is good at many things. One of those things is apathy. It is an apathy about the services and their hardships. People are even tired of hearing about the hardships. After all, we are talking about volunteers. “We didn’t make them join the service.” That is true. But we elect our government, and that government influences what happens to our military. And frankly, those we elect don’t get it most of the time. They never served or deployed.

Life in the service is a voluntary life of sacrifice. Even in the best non-conflict circumstances, it can be a difficult life for the service member and the family. You experience dangerous training deployments, high stress situations, and personal strife from long deployments. I know everyone experiences stress in their lives. I am just saying the average service member’s fun meter is usually pegged a little bit more than a civilian.

When you send a person into a shooting war, and they spend some time there, they change. Most of the time, they change a great deal. Don’t take my word for it, do some research. I was never in a shooting war, but I have been around more than a few folks who have. Men and women. They change.

Our manpower numbers are so thin that we are putting our military through an out of control machine of deployments. The same people deploy over and over. You go for months deployed, then a year or so home, then back, then home, and on and on. Change upon change upon change. Over time we have accrued all these professional warriors who like being deployed more than being home. But then we sweep them out like so much dust and dirt. They get therapy in bucket loads, but they are out. Their identity is gone. Sorry, we need the money.

We reduce costs by reducing manpower. It is the quickest way a corporation can raise cash in house. Our Military is no different. “The missions have changed” or “our strategic threats have changed” etc. Sure they have. But while we reduce manpower, we continue to buy unnecessary vehicles, systems, doctrine, and support. I will cite the V-22 Osprey as one example. What madman dreamed that aircraft up? “We need speed, more lift, etc, due to our threats”. Is it cheaper than two helicopters? One Osprey’s fly away cost is 67 million dollars today. The workhorse in Afghanistan is still the Chinook. Fly away cost 37 Million. The Chinook seats more troops, can lift 50,000 lbs which is only 10K less than the Osprey, and is definitely slower. As for the speed issue, the latest Sikorsky experimental helicopter is in the 400 mph range, comparable to the Osprey. My point in droning about all this is we are paying twice as much for more complexity, an unproven over time design, and less troop capacity. Ouch.

Which leads me to the point of all this. Our military is stretched too thin. In 2009, the Army had 548,000 active duty. With a mission to bring in over 80,000 new soldiers per year, the force is 1/7 untrained and unprepared to fight. Since a percentage is always leaving, meaning they don’t fight all the way up until the day they muster out, there is another hefty number not able to fight. Ouch. And since not everyone in the Army is a shooter, but may be a supporter at home in an office, this cuts the availability of a fighting force even more.

Is the answer more brigades? This is the structure the Army is adopting, the modular brigade concept. Brigades cost big money by any estimate. The GAO estimates 3 to 4 brigades and 3 headquarters of approximately 20,000 soldiers (brigades and headquarters combined) would cost about 2 billion annually. There is no free lunch, unfortunately. The Osprey’s cost is at 27 BILLION as of 2008. Think about that. That’s more than a few brigades.

A soldier can be trained to do many many things. They are cheaper, more flexible, and the rate of return is greater for your money. The more you have, the easier it is to do things. A soldier can run, climb, swim, think, and sacrifice. It’s all about boots, especially in today’s up close and personal combat situations. That is the one lesson we haven’t learned from previous conflicts.

So when you see all the nice and impressive vehicles and aircraft at the parade, look close. You will see a soldier somewhere. He or she will look tired, and bored. They have changed permanently, and they are waiting to go back. Because they know it’s coming, and there’s no one else to go.

Push it on the stack

May 27th, 2011

Medium size metropolitan Saab dealer… 8:00 a. m. 2 waiters on the counter already. Been waiting since 7:30, I thought we opened at 8. First one is an oil change… get the oil draining. Second one has a window that won’t go down, push the oil change on the stack, off with the door panel… motor shorted… price motor. Car already in shop needs to get to bodyshop asap, but needs alignment first. Push window car on the stack. Almost finished with alignment, customer needs to go for a test drive for some noise she hears. Push alignment on the stack.

We don’t hear the noise, but she insists on driving till we hear it. A lot of people are getting antzy back at the dealership. I suggest letting me drive, and she agrees. Big mistake for her, as I drive straight back to the dealership, and tell her we just have to keep the car till we hear the noise. (Later that story has a happy ending, just a bent heat shield.) Pop the alignment off the stack, completed and off to the body shop. The window motor sold, and installed and out the door and popped the oil change off the stack. LIFO. Done.

9:15. Ready for a new round.

The Shuttle and the Solar Impulse

May 16th, 2011

Flying machines are radically different from each other depending on the job they have to do. You would think that flying around in air would make them all pretty much the same, more power than weight, aerodynamic and the rest. Today the next to last shuttle flight took off. Talk about power, the 3 main engines provide 1.2 million pounds of thrust and thats not counting the 2 solid rocket boosters which all push the shuttle from 0 to 17,000 mph in around 6 minutes. I don’t know what that is in horsepower but it’s a lot.

Also in aircraft propulsion news, the Solar Impulse made it’s maiden flight and landed in Brussels this week. It’s the first solar powered aircraft and is an ungainly looking thing. But it is thrifty, and uses no fuel. It’s four 10 horsepower electric engines push it along at a blistering 60 mph, a challenge to land at an international airport when the craft goes so slow. You would think high winds could give it fits, also. But it is pretty cool. Not likely to get us to the moon.

I’m torn by which one I’d rather ride in… I think I’ll take 1.2 million pounds of thrust, please.

Rockets in the Spring

February 13th, 2011

When your hobby is building and flying airplanes, helicopters, and general kid/man stuff, winter is the time for preparation. It is a time when goofy ideas begin to turn into visions within our grasp.
Right now, in the Rineyville Skunkworks, we are getting ready for the next chapter of aviation. But more on that later. This is where and how it all started…

The Day of the Underwear.

In Vine Grove Kentucky, we had a little tradition.
Every 4th of July, to celebrate the birth of our great nation,
we launched a pair of underwear into outer space.

Equipment on Pad 13 (we spared no expense)

The Launch Vehicle (just like you would see at NASA)

The Payload, complete with special re-entry coating

The Flight Ain’t she a beauty! Up, Up, And Away!

Another small step for man…a giant leap for Kentucky. And,
another pair of underwear into outer space!

This year, possibly in April, we will make the aviation community cringe again. We will launch the sacred Saturn V Rocket (almost complete):

Launch it, we will, with the mighty launch controller:

And of course, the finale will be the space underwear launch (candidate yet to be chosen). We have begun construction of the launch vehicle. Stay tuned.

Passports, Dinosaurs and RFID

December 18th, 2010

The wife wants to go to Canada next year so off we go to get passports. My last trip overseas was on Uncle Sam, so a passport was a new experience for me. It finally arrived in the mail and looks pretty hi-tech, so I delved into it’s properties.

It has a machine readable code on the data page (the one with your picture on it) so scanners can read your information. This has been a feature since 1981, but I had noticed this small block on the front. This block signifies an inclusion of an rfid chip, which has been in passports since 2007, and this includes certain biometric data about me, and even my picture is encoded.

This chip was originally mandated as a way to speed up the immigration process by making scanning easier and faster. The rfid chip is just a more modern machine readable code, but now the digital world makes it easier than ever to steal your identity. Any rfid reader can read that code, and the more power the reader has, the farther away it can read the data. To deter that problem the cover is supposed to have a radio frequency shield to deter unauthorized scanning of your passport. However all this goes away when you open it.

There are projects afoot that will encrypt the data so that only authorized readers can access it, and being paranoid I think this is great, but I suspect this will only lead to escalation by the bad guys. With every digital hole that is plugged they seem to worm their way into another one.

Digital parasites have evolved alongside our technology. Parasitism is a way of life on this planet, and it bothered the dinosaurs as much as us. This may seem that we are locked into an evolutionary arms race now between white hat and black hat hackers, and maybe if one side or the other wins, we may all be the losers. Maybe we need predator hacker scumbags to make us stronger, much like the constant warring between europeans made them (and us) the dominant power on this planet.

For now, I think I’ll wrap my passport in aluminum foil.

Paper is dead

November 27th, 2010

I hate to say it out loud. I love paper. I used to try and make it out of a bunch of old rags, mixed into a paste and pressed out to dry. The sunday morning paper is a comfortable old friend. The stacks of books on the wall don’t want to leave. There are albums crammed full of pictures, snippets from magazines and articles I can’t do without.

I read a lot, but lately it hasn’t been on a paper background. It started with computer screens that got connected to the internet. There isn’t enough wall space here to stack the number of books you can access on the net. But now, with Ipads and whatnot, you can access all that stuff from anywhere, and you don’t have to wait till you can get to the library or the bookstore or wherever. Your kindle can download anything you could possible want to read. And it all packs into some little thing you can put in your pocket. (Well, everything except the Ipad)
Ebook on Ipad
I’m still keeping the sunday morning paper as long as I can, even though it is changing also. The paper is smaller now, and ad content usually covers three quarters of each page. Still, it is paper, and it will be something our great grandchildren will only see in museums.
