I do not see the need of an engine for this kind of sailplanes, the principles of sail plane it is to fly just towed up and with the termals noiseless.
you are burning fuel and making noise!!! no sense.
I dunno, but there`s a lot of cooling air going past...Actually, these plastic aeroplanes get so hot in sunshine that it is illegal to paint them any colour but white! Honest - even the orange visibility markers on the wing tips cannot be above a certain size. All in all, the sun probably gets the tail hotter than the turbines.
@GollumLeVelu Heat andUV are both enemies of epoxy resins. I had a day job at Lasham repairing gliders, and recoating with new gel. Very labour intensive! The gel coat protects the epoxy in the structure, if water gets in it can cause some delamination over time. As I said, it's the sunshine causes the problems!
The great thing about this is you fly a glider sequence - but don`t find yourself committed to landing. A 500kg glider with a glide angle of 50:1 only needs 10kg of push to stay up all day.... a little bit more power and a few thermals gets you back up to fly another sequence. Cheaper than a 4000` aerotow!
You dont get the point of this do you. Its a fking sail plane with engines used on model jets powering it, thats just plane awsome. *shitty pun intended*
I've seen this show and I have to agree... there's no sense in having a SAIL plane using tin jet engines... it's not for me. I've glided and the "sound" of the wind is the thing that makes a sailplane what it is...
A jet engine is only for the takeoff, the pilot is only showing what is the twin jet capable of with a light waight sailplane, just a demonstration, which seem to be very good. I love the idea of an engine, it makes things a lot easier.
well, I went to Airventure 2009 and the jet sailplane that was in the show used the engine all through the show. So, that is not only for taking of but for doing the show. My father, 40+ years into flying agreed with me, that is not a sailplane and takes all the fun about sailplanes. I've seen the other shows, with sailplains sailing and it much nicer, the sound of the wind passing through the wings is what drives me nuts.
Yeah, sound of the wind is fantastic, there you are right, but this show and this engine is about take-off only, and if you loose height or you have an emergency, engine will save you, the pilot here is showing only the potential of this twin jet and it possibilities, i dont think it has enough fuel to fly to Europe from USA... after take-off you fold your motor, jet or proppeller and ready to fly as usual you do with a sailplane.
Oh, I thought when you crossed over your left hand to adjust the controller's position you checked your watch for TO time. That was super critical in the Bede5jet- WE had visual sight gauges and timers plus watch for that. Hammerjet is Dave Hammer-he has a jet Caproni sailplane. Flys SMART jet for Bob.
I like the watch check on takeoff-- another flying fuel emergency--- what do you get at airshow weight-10 minutes or less? I hear from hammerjet from time to time-- he loves his
I'm not sure what "watch check" you're seeing. I do close the vent window on takeoff because the air blows directly in my face. At airshow weight, I can fly easily for more than 30 minutes. An hour if I'm not performing low level aerobatics. Who is Hammerjet?
Sounds easy. How do you handle retracting twin 24" propellers? How much thrust do the fixed-pitch turboprop propellers produce at 100 knots? Will JetCat provide support a manned project? Be sure to post videos when your turboprop sailplane is finished.
i dont know what turbines these are, but jetcat is largest manufacturer of these. these look like a pair of P200's class. Jetcat does have a P200 Turbo Prop, but currently sell the PT5 Turbo Prop, which is from their smallest turbine and produces 55lbs of thrust. Their P200, Turbo Prop I understood was about 160lbs of thrust on the prop.
It is my understanding that JetCat does not want to support any manned aircraft projects due to liability. The PT-5 Turboprop is rated at 55 lbs with a 27" prop. With a folding 18", you'd get about 25 lbs static thrust, and almost nothing at 100 knots. The P200 turbo prop is not available yet. After they've built a few hundred of them and tested for continuous high-power use, we'll see.
it would be nice to see. jetcat doesnt want to support, do to extensive faa requirement and cost. i've had my thought about it, for a kitbuilt, like the sonex or something similar. would be interesting. as for their electric sonex, ya, weight is an issue for glider. for conventional powered aircraft it is - fuel load. You have no fuel load, so, overweight [unless solar on that same motor :)] And nope, never floan glider. Just 1,600 hrs in fixed wing powered aircraft. Cheers
and for fold props, i think the folding prop topic, like bailey's 18 hp, for the swift pas is the a thought. but then you also have electric.... Sonex built an 80hp electric that has 1 hr flight time, for their plane. Flew at this years Oshkosh.
The electric Sonex motor weighs 50 lbs! I couldn't find information on the weight and size of the batteries, only that each battery must be contained in a "safe-box" to reduce the chance of fire. Also, in the interest of safety, they remove each battery for charging. I'd guess the batteries outweigh the motor. Just the wiring for running a 270 volt, 200 amp motor would weigh more than my jet engines. Remember, the aircraft weighs under 400 lbs empty.
Solid fuel is used on powered and non-powered aircraft for JATO (jet-assisted takeoff) and burn quicker than the turbine engines. Also looked like the pilot was controlling the engines with a simple RC radio instead of a dashmounted throttle control--something I wouldn't have done!!
Actually, the throttle controller is hard-wired to the engines. It was designed specifically for this application. It is not an R/C radio transmitter. The cockpit is very small, so the most convenient palcae to mount was on a leg strap.
You cant buy one this guy spent hundreds of hours making it.
You can buy those 2 engines for around 10 grand. I remember speaking to him and he said it burns something like 11-15 gallons an hour which is very thirsty for such a light craft but then again all jets are thirsty.
Its still considered a glider just a self take off one
I sure would love to have my own personal U2 spyplane! and with that glider planform.. it would seem that engine reliability is a mute point, you are as safe as a kitten : )
Another quick question, does this have a Supplemental Type Certificate or multi engine land or is it still a normal, no medical glider? Because it sure beats the crap out of a PA28-161 and looks like a blast to fly! Thanks again!
No this is not soaring in the usual sense. The jets are capable of self-launching, and are retractable for normal soaring flight, but tha makes a pretty boring video. Te airshow work I'm doing with the jet sailplane is stimulating great interest in gliders and new aircraft technology. Bob
Bob Carlton of Albuquerque (NM) owns it March 26, 2004 at the Conway (AR) airport. The jets are manufactured by AMT USA (Aviation Micro-Jet Technology). The twin jets product ninety pounds of thrust@ 112,000 rpm climb rate 500 feet/min. The Jet Glider carries five gallons of fuel for about 18 mins full power Each engine weights 5 lbs& cost $5,000. The jets are are raised and lowered on command into jet.
I know some German sail plane owners which are using a retractable AMT turbine (normally for model aircraft) in their olanes to have a light, simple and compact pusher if there is no thermal lift.
those jet engines look like something you would use on a scale rc plane.

Can you please give us some additional information:

- What type/model of Plane are you using
- What is the highest speed and travel speed
- Did you build the whole plane by yourself
Kind regards!
