I was shown this and thought that some of you would like to see it.

TOO cool!

Can't wait to see the take-off from the ground...maybe laying on a large skateboard?

That is what I am saying, when he can take off underpower and land underpower I will be impressed. You can make a brick fly if you strap enough rockets to it. Look at all those motors he has on that thing.

I looked over that page and it doesn't say much about abilities of this machine, it says that he can fly level but nothing about climbing??? Can he gain altitude?

Yes he can fly level. He can gain altitude and he can also bank turn. I have seen a few videos of him testing it and in one of the videos he does 3 banks turns before deploying his chute and landing. He is capable of moving small flaps on the wings that all him to roll side to side.

Here is a youtube video in which a small overview is given and flight.

If you looked over the page enough you would see that this is the first one and they are already making the second. More time in the next one. This must be a very exciting project to these guys! The motors are all model airplane jets. I am sure they will have their sites on takeoff and landing, though I think that the parachute is a great idea to get down safely.[/color]

Say it is not so. I was thinking that was a lens for a camera but when you mentioned it all I could see was duct (duck) tape.[/color]

Later,

I have several friends that are into the jet r/c planes and the engines that I am familiar with are the same brand but are about 75% the size of those he has there. Those things pack a hell of a wallup even sitting static on a driveway, throttle it up and one of them will clear it completely of leaves for about 100 feet. Once airborn and getting air rammed in the intake, their power increases dramatically.

He can climb - at the end of the video it specifies the rate. I don't remember the climb rate (and don't have time to watch it again) but he could climb at 100km/h at, I think, 100 meters a minute. His limitation is fuel - he's limited to a 5 minute run in the current configuration.

Well, I stand corrected. I had some more time so I went and looked around some more and I will admit it can do more than I thought.

Being able to climb is what impresses me, with that you are flying. Before that it is just extending a glide. I wonder how he carries fuel? Compressed or just in tanks?

Those banked turns he did are pretty cool, I could see something like this being a big hit at airshows and other stuff like that.

Those engines have a small chip that controls their startup process. First, they spin the turbine up with a DC electric motor (the small pod right on the intake of the turbine). Once the computer senses they are at full electric motor supplied rpms, it injects propane into the combustion area and ignites a spark igniter. The propane usually comes from a tiny cartridge very similar to a CO2 cartridge used in pellet guns. Once the propane cycle has ignited, the DC motor turns off and the engine continues to spin faster and faster. Once the computer senses it has reached enough RPM for the JP4 (somewhat similar to kerosene), it starts feeding in the real jet fuel and shuts off the propane feed. From there it's simply a matter of metering the JP4 for throttle control. It's really quite a spectacle to just see one of these relatively tiny things ignite, chuff and spit fire, then whine up smooth as silk as the exhaust outlet turns cherry red and the noise becomes almost unbearable.

It is also quite a spectacle to see a twin turbine propelled model jet turn into a 200mph Frisbee when a homemade fake air to air missile implement breaks off and takes out the horizontal stabilizer. <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" />

Gree,
Where did you learn that phrase? Were you ever in the Air Force? We used that term a lot at my first assignment... we weren't talking about US jets, we would use that phrase to describe some of the older MiG designs. That phrase brought back some good memories.

When I went through USAF pilot training, the saying was, "If you put enough motor on it, you can make a barn door fly, but they had to put two of them on the F4!" Nicknamed the Lead Sled.

But this guy looks more like Buzz Lightyear...

I wonder why he just doesn't run off the edge of a very high cliff to launch.

Running with that gettup might be a little tricky. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

" I wonder why he just doesn't run off the edge of a very high cliff to launch. " That reminded me of this dude...Loïc Jean-Albert. Who flys about 15 feet off the ground at 100mph in a wing suit.

I am not sure where that phrase came from. I just like using it when it fits!

<****.

You guys had real trouble beating the Mig 15 (a Sovjet 40's jet design) all the way up to the Sabre jet which was introduced halveway in the Korean conflict. And then you made the same mistake again with respect to the Mig-17's and 21's (both 50's design) in Vietnam. They were the reason the board cannon was brought back from the moth balls. An detail that had been left out in the orginal F4 design. And we can go on with the Mig-25 foxbat, Mig-29 fullcrum, Sukhoi-27 (70's and 80's) with the last two jets being able to do manouvres that even the best US plane F15 eagle can't do.


If the Sovjet planes are inferiour (and they are in some aspects) then it is in the area of aviatronics and fuel efficiency. But most certainly NOT in aerodynamics or even construction.

Believing otherwise despite ample documentation against it is being brainwashed. But for some of us here that is a normal condition

Wouter,

For an Air Force person (of any nationality) to rag on the planes of their chief rival is normal. Take a look at the friendly "discussions" the ensue here between the F16 and F18 guys. I'm sure that Russian AF pilots have similar sayings about US planes.
