Renner, thats very interesting stuff.

I'm going to stick my nose in a few places and bug my brother-in-law about who's doing what (he's still contracting at Wright Patt). So these guys said they beat the efficiency of a turbofan or turbojet engine with a pulsejet?

Not surprised by your comment about Pratt&Whitney, I've got little good to say about P&W, some sleazy individuals over there...

Hmm, I can tell you at least Lockheed and Boeing are not putting money into PDEs, unless someone is lieing to my face. Wright Patt's last sponsored PDE research RFP was more than 15 years ago for drones, at least according to my GSA search.

Who's spending money on PDEs for super or hypersonic propulsion use? Last I heard the money du jour was in laser sheet ignition for supersonic combustion.

So if some skunkworks group has scored corporate cash to do research on pulse jets under the guise of new transport or other vehicle applications, I need to talk to their venture lead. My leprechaun sled needs funding bad, and I figure they'd be the person to get me my dough.

+1 on Renner's warning about being careful with this stuff. If you ever get a chance to hit Bolz Hall over on campus check out the compressor on display (at least it used to be on display what ten years ago). Shows what happens when you get a shock wave formed in the area of the outer lip of the compressor blades. Kerplowee. Shockwaves and carelessness = bad. BTW - I did that to it, my claim to fame (infamy).

P.S. - combustion without a chamber is in common use, we call it an afterburner.

I can pretty much guarantee you pulse technology is not used in the Aurora or any other operational Black Program aircraft. And I won't say why not, so there. SCRAMjet tech, maybe...

That site, erm...whoa mm-ok.

This little gem has got to be the most Fred Sanford I've seen since my grad student days, made me spit up my Diet coke:

"Liquid methane or liquid hydrogen is ejected onto the fuselage, where the fuel mist is ignited, possibly by surface heating. The PDWE works by creating a liquid hydrogen detonation inside a specially designed chamber when the aircraft is traveling beyond the speed of sound. When traveling at such speeds, a thrust wall (the aircraft is traveling so fast that molecules in the air are rapidly pushed aside near the nose of the aircraft which in essence becomes a wall) is created in front of the aircraft. When the detonation takes place, the airplane's thrust wall is pushed forward. This process is continually repeated to propel the aircraft. From the ground the jet stream looks like "donuts-on-a-rope."

I think one of my profs just rolled over in his grave. Ugh.

Meanwhile, work progresses on my leprachaun-powered sled. Looking for investors. Updates next Tuesday.

Because i can. Dude im not trying to compare a porsche to a truck, i have no clue where u got that at. I thought if you drove a car, you could tell how it handled?

No. Only if you argue about them in internet forums can you tell how a car handles.

Driving is not involved.

Heed the last line: "However, despite this advantage, pulsejets are seldom considered to be practical power plant due to their high fuel consumption, low efficiency, noise, and significant vibration levels. Today, they survive as a powerplant for model aeroplanes."

If it "was" and "isn't anymore", then, in engineering at least, there's a reason. Nobody throws away good engineering. As opposed to fashion and religion....

Good for models and dorks in gokarts in New Zealand though. Whatcha building?

Did the short bus just stop off at CR's Login Screen or something?

We got a whole wheelbarrow full of dumb in here at the moment. Man!

Wow. Those of you who can't catch that he's as much bagging on Brits as Americans, well, here's $5. Buy a clue.

Wait, have a $20, go back to school.

Another typical Top Gear segment -> 50% Entertainment 50% Brute Truth. Loved it.

P.S. Lightnings rock

Ford is dumb. I've no doubt that that happened - that they worked with State Farm and probably other major insurance corps on certain design sections of the new Mustang, with the insurance folks mumbling about lower rates for Ford's new sports car.

And I'm also certain that State Farm and crew had zero contractual obligation to make any feduciary changes to their policy rates for Mustang customers.

The insurance companies just reduced their risk liabilities, improving their profit margin, and Ford just got pwned.

The video is labeled wrong and totally false.

 

The part that flies off is the plastic ram-air cover and it doesn't do anything to his hand/arm. It is Brock Davidson if you want to email him and ask him for yourself but he races at Kil-Kare all the time if you want to see him un-injured and still racing to this day in person.

Glad to find out he wasn't seriously hurt.

Wait, are you shitting me? He's parking a brand new ~$70,000 Z06 in a condo/apartment complex parking lot ?!?

Wow, just wow.

Dove the John Pennecamp national park off Key Largo a few times. Key Largo, IMO, is the "unknown" key for divers. No frills, no college drunks fucking up the scenery. No overpriced daytona beach BS like Key West. Just the carribean, clean water, and affordable bungalos for rent. Being next to Islamorada (the "sport fisherman's" Key) its not hard to charter a really great boat and avoid the whole 50 person cattlecar dive boat circuses too.

The John Pennecamp reef is amazing, I recommend it highly. And base yourself in Key Largo to avoid the tourists and save a buttload of money.

(not real) +1, He has to push his shifter down and into first to even get into reverse...

Oh I'm betting its quite real.

Never underestimate the heights of stupidity your fellow man can reach if he tries hard enough.

Question on the video of the "GSXR750 throwing a rod thru the rider's forearm": anybody know if it actually severed his arm or just pulped the bone. Looking at the vid its not easy to tell, but I sure HOPE that thing that flies forward and lands on the lane in front of him is his mirror or the piston and not his hand.

What's the big deal??

Her nose.

I Like this one:

Rice-a-RIFIC!

They won't be bought in droves. You won't be seeing them everywhere. You will be seeing Mustangs everywhere, but they're a successful car, and this car is based on it so the folks that don't know what to look for won't see a difference. Just like the 03/04s.

The 03/04 Cobras were $5k-$8k less than that and you rarely see those on the road. (Although alot of folks think they see alot of them)

...unlike the fbods, which everyone could afford, but nobody wanted to buy ....

sorry, that was just too easy
