Dealing with communist marxist china, during their modernization phase where they enslave their people and use free trade as a weapon to destroy the free world, by stealing our manufacturing infrastructures, and shuttering  small family business economies with the slave super stores, like walmart as an eample that exposes what happens in a world that commits slavery the slavers take the cash flow, walton family take an equivelant amount of cash from the american economy as 30 % of our entire workforce. In a world of slavery (GLOBALIZATION) america has 400 of the worlds more than 1,000 billionaires, 40,000 millionaires, while the workforce 80% + make near or minimum wage and 56 % of our youth between 18 and 29 are out of work. Seeing the results of free trade and permitting it to exist exposes a level of political criminality so massive, that our ruling electorates are no longer fit to serve our country. In fact they do not serve our country, they go into politics to have a go at the lobbies money, the slavers, bilionaires give millions to each corrupt senator, congressman, judge, official, via some criminal lobbie to overlook the crime of slavery long considered a serious felony in our nation, for common man, however the super rich elitest, pay their way into slave goods retail businesses, without paying any import taxation, thereby actually stealing accrued taxation that before globalization supported our infrastructure. The outcome in all companies who engage in slavery following americas lead, all find themselves in the same economical collapse, without accrued taxation to support their country. now we have a cooperating president giving them free trade ports, and selling property and geophysical american assets to a country whose basic foundation is to eliminate the free world, OBAMA is already ruling by executive order, bypassing the senate and congress doing as he wishes, americas first homosexual dictator, who commits sodomy on the US Military then discharges snipers who engage in consentual sex with the opposite sex. When and how are we gonna get rid of this guy who follows stalins methodology with ACORN election frauds, unprosecuted, giving them 3 billion in stimulus for the upcoming 2012 electionfraud---joseph stalin said it well for obama, when he said " He who votes doesn't matter, but, he who counts the vote, counts ". he assigned acorn et al census responsibility, which includes insuring voter protocol. watchig the political arena exposes just what a lawyer will do to get elected, like obama spending what it would take 3,500 years to break even on his president salary, just to have a go at lobbie cash, and the final pardon sale, like clinton who broke the record with more than 300 pardons for real criminals with cash, unfortunate to have had a judge assigned to their case who was already boughtout by one of their competitors, or elected to prosecute them in spite of their cash or perhaps they refused to be extorted for their crimes, whatever, our; city, county, state, federal etc electorates have elevated themselves into some form of nobility enacting predatory laws to extort america with laws invading every venue of life. It like the judges are little kings and their circles of lawyers are like princes---Its way past time to change and restore americas independence, making in america what america consumes, or making imports pay for their stolen accrued taxation. a child in economics 101 can understand accrued taxation, created by domestic goods, and what happens if you give it away to countries whose governming principles are to eliminate freedon from society. and thats what barry the sexually aberant indonesenian is doing to america, his every act is against the best interest of our nation, every word coming outta his mouth is a lie.

JackieCox—I certainly agree with you.  I worked in the aerospace industry some years ago as a team member having engineering responsibility for the Air Force relative to the thrust chambers and turbo pumps of the Titan II missile.   It was fascinating work and I definitely can state that, at one time, the United States had superiority over other countries  when it came to space flight ( manned or un-manned).    The thought of losing our edge when all of the great NASA, supporting vendors and Air Force employees retire or die is extremely troubling.  You just don't get that back in a decade or two.  How on earth our government could roll over and dismiss all previous efforts in this important technology is beyond me.    If you look at federal funding for NASA you will find it to be miniscule compared to the budgets for several other agencies.   I have no idea as to our national priorities but it does appear we don't worry much about our national pride.  Allowing the Chinese or Russians to do our work for us should make every American ashamed and it puts us in the position of asking "mother may I" every time we "need a lift".  Disgraceful in my opinion.

when the present admin is removed from power perhaps we can get on with real science and technology in both manned and unmanned aerospace equipment that can fly in and out of earths outerspin operating independently of earths magnetosphere. The shuttle, our worlds first and only independent aircraft reusable, capable of servicing chandra and hubble is gone now , the new generation shuttle 2 scientific team that took decades to develop is also gone, and now some pseudo-private contractor, as if all suppliers to NASA, or military were something other than private contractors, in some public relations stunt, to get unwary investors to invest in barrys favorite; elons (iron man) spacex, tesla, solar city, all of which were aquired with hostile takeovers, and have lost money from day 1, with obamas czars continuing to dump billions of taxpayer money down the drain to ultimate bankruptcy, for stupid items like falcon, or an actual missle capable of hooking up with space station, then splashing down, a repeat of our 60's space engineering sputnick low earth orbit vechicles, as if it were a grand advancement because a private contractor did it, creating the illusion that all Military-NASA's suppliers are not private contractors, in some sort of charade, thinking the american people are too stupid to tell the diffference between a bankruptcy expert supplier and more viable contractors like, lockheed martin marietta, and the thousands of part and assembly suppliers. I have watched this south african draft dodger, a pal of barry, who funds his attempts to produce electric cars, he claims to have ivented when he actually stole the company from eberhardt, the real lead designer, pretending to try and break into the automobile industry, by importing his cars from finland, pretending they are american, or his solar city, near exactly the same as solandra, or the solar panel company crushed by chinese federal intervention by funding american-german designed solar panels at half the cost of making them in america, because each average chinese slave, gets 3.8 cents every american gets 100 pennies for the same work, or, our senators, congressmen, president, lobbies, judges pretend globalization and free trade is not simple slavery, where the slavers make the money, while nearly everyone else is out of work or viable business. a simple act of eliminating import taxation, which used to discourage slavery by taxing imports in a proamerican science and technology effort, resulting in the worlds greatest manufacturing infrastructure, and huge small family business economy, contributing more jobs than people,+++ the accrued taxation reuired to keep america ahead of the world, protecting our agriculture who make 1/3rd of the worlds food supply, by having a military capable of protecting our shores from the tyrannical starving world---To watch obama et al destroy NASA, the U S Military, post office etc etc, or the basic working americans whose jobs spinning off other jobs contributed more taxation to our treasuries than their salaries, its what america and europe used to become wealthy and increase their quality of life, ended and replaced by slavery, or so called globalization or free trade, where a cartel of oligopolies produce their landfill (fashion) with slaves, and resale it back to us with poverty stricken hirelings. I give the american politican a competency level of -.03 out of a possible 10, or the team of criminal lawyers, judges, politicians, enact the laws lobbies clients writep for them to enact, ignoring americas independence, gone with import taxation, and the illwill of criminality currently occupying our government offices :city, county.state. federal, international electorates, where they control the newsmedia telling us what to buy then selling it to us. they think we believe whatever we see, hear, are told and read, in a nation where they control all information sources of consequence, or so they think, these criminals are fueled by abnormal lust and predatory greed. The true americans in unelected office need to meet independently of political czars et al, declare marshall law, adjourn senate, congress, repaint the whitehouse, and restore honor and respect in government, in our independent nation making in america what america consumes while exporting to the world.

I remember the longeze and varieze designs he created that were canard designs like this one.  The design was supposed to be very safe in that the canard forward wing was intended to stall before the main wing, thereby dropping the nose of the aircraft and making it really hard if not impossible to create a stall condition in normal flight.

This was interesting to me for another reason.  It turns out, that control surfaces forward of the center of gravity tend to destabilize the craft as the speed increases.  That is the reason for the retractable bow planes on hte newer submarines and the folding bow planes on a few of the WWII ships.  I believe we learned this from German submarine designs which had a warning about speeds over 9 knots when the bow planes were not folded or retracted.

On the 688 class attack subs the bow planes are mounted in the sail, which is considerably aft of the bow location, this helps in reducing the destabilizing effects.

Another design with a forward canard was the XB70 Valkyrie.  I saw the only remaining one at Wright Patterson in Ohio.

I don't recall any designs from Rutan that used jet engines but I think I heard of someone putting a rocket engine on one variant for some kind of specialized testing.

I agree, Ivan. It does seem to have the Burt Rutan touch. Has Rutan made something similar?

I think that's an excellent observation.  Fixed landing gear AND jet engines.  Maybe I'm missing something but this does seem a little strange to me.  I am a pilot ( fixed wing, single engine ) and the drag created with "gear down" is definitely there and noticeable with increased air speed.    I do applaud the Air Force for undertaking basic research on this type of air craft.  I suppose we have given up our maned space missions but hopefully, we won't let the Chinese do our reasearch also.

The last paragraph suggests to me some type of closed loop feedback software control system.  In addition to aerodynamic advances, I wonder if they are also embedding sensors on critical areas of the wing in order to report real time data back to the main software controller.

Very interesting airplane!  It looks like a Burt Rutan design.  The jet engines are certianly an interesting part of this design but it seems to limit the flight time with the once through lubrication system.  The engine seems to have a 25 hour time between overhauls so I am wondering what must be overhauled in the engine and just how much of the original cost this entails.

Given that jet engines are more efficient at higher speeds I would question their use here in an aircraft design that is apparently not that fast.  The evidence for this is the fixed landing gear.

Yes, the JETCAT P2000SX is a great engine.  I thought it sounded familiar.  It is used in scale model jets.  I have seen some that go over 200MPH real speed.  It was wild.  The power to weight ratio is just over 10 (for the engine alone).  This is good.  It is interesting that NASA and the Air Force are basically using large scale model airplanes for research, isn't it.

Wow!  How cool is this!? Love, love, love, the JETCAT P200SX. Thanks for this... I can forget about teaching classes for the day.  I'll be busy watching tiny turbine Youtube videos.
