The engine has an RGB attached to the power turbine that, combined with the pitch assembly, slows the prop RPM down to a couple thousand RPM. Most of your bike motors run at around 14 thousand RPM and use a transmission to change that high RPM into torque. An RGB is similar but functions differently and therefore this engine doesn't really work on a bike. 2000 shaft RPM on this engine has tons of torque behind it for spinning a huge prop at that speed not for a bike. 2 different things.
WOW, that motor must be one of the slowest Boeing EVER MADE by FAR. The bike videos on your website with this motor installed looks like the bike barely reaches 50 mph with this motor!!! What a waste of time and effort this must have been. It barely propels a 500 pound bike beyond 40-50 mph, JEEZ, LOL, LOL.
@computerfreaq17 Absolutely they have... that's what this was used for. The U.S. Navy had 2 of these coupled together through a gear box to run a generator that powered electronic mine sweeping equipment.
@vroomba03 This was done at a storage unit, not my home. Otherwise I don't think they'd appreciate it too much! The storage unit owner thought it was pretty cool though!
@Bamchucknorris I had gotten that for just $2000. I've since sold it though (for about the same amount). These older engines can be had pretty inexpensively. But parts for them can be very difficult to get if needed. That sound at :07 is the fuel being ignited. Up until that point, it was just the electric starter spooling it up. Great sound though, I agree! It's what made me want to get mine as well.
@Bamchucknorris I had located it through eBay, as well as a T53 I've owned and two other turbine engines. My new site has a turbine classifieds section that will soon have turbine listings and sources as well. The site is TurbineBase (.com)
The startup sounds are worth it alone - lol. It'd be so cool to fire this up as you pull away from the mini-mart in something like, oh, an AMC Pacer or a Gremlin - LOL.... Awesome. I'm jealous ;)
i seen a truck in a magizine it was a 99 f250 that the guy had always claimed it to be just a chipper diesel and exhaust turns out he had a garrent jet motor not the turbo but a garret idr what model i wanna say like 102 somethin gidr but it was pretty cool
with no load attached wont the power generating turbine spin up and let the 160shp (-2% for reduction gearbox, -20% due to turbulence (entropy)) out as forwardthrust on the end?
No. First of all, the 160shp rating is the maximum power output at 100% engine rpm. I never went above idle because I had no load attached to the output shaft (it would have automatically shut down or exploded otherwise). This would never make forward thrust, as the exhaust is directed straight up. Turboshaft engines produce virtually no thrust.
So for some reason I just pictured a Volkswagen microbus, rolling in a perpetual wheelie, with a pair of turboshaft driven flywheels and an oversized Segway logo on the front.
I set my control panel up to run like this: first, I energize the boost pump (a 12v fuel pump to deliver fuel from my fuel tank to the engine). Then, I press and hold the starter button, which does a couple things, including energizing the ignitors. Once the engine comes up to speed, I flip the fuel-starter solenoid. That gets fuel flowing through the nozzles, which ignites, and spools up the engine. Once the engine reaches idle, I depress the start button, turning off the start-fuel solenoid
That all having been said (and from someone who does seem to have some turbine education).... you CAN bolt an engine like the Boeing 502 directly onto something, like a car (a bit big for a kart). This is a turboshaft engine, and like most turboshaft & turboprop engines I know of and have owned, it has a reduction gearbox. This engine will put out plenty of torque in its current configuration. You CAN *NOT* hold the output end from spinning with just your hand. Not with the gearbox attached.
the prop to prevent it from spinning but its not safe because by not allowing the turbine to rotate it creates a back pressure in the turbine nozzle which would result in surging of ng and possible compressor stall. so that y u need a reduction gear box to allow it to rotate since part of the torque is the inertia of the rotating prop or appliance.
no you cant do that because if u want to get any kind of acceleration you would need torque, and the torque in a turbine engine is produced at a very high rpm! for example at my old school in turbines class we test ran a pt6a-27 at ground idle it produced 35shp at 20000 rpm Nf with 300 ft lbs of torque and full power it produced 450shp @ 30000 Nf stabilized w/ constant speed unit and 35000 rpm Ng w/ 1200ftlbs of torque. and thats a baby in the pt6 family. But during spool up u could easlily hold
The interesting thing about the free turbine. When I was going through A&P school. We were in the powerplant classes and the instructor told us about the PT6 turboprop. You can hold the prop blade as it spools up and just let go and walk away. Seems some of the marines use to do this. Or so I was told. If you could get your hands on an alison a250. That would make one fast lightweight gocart.
This is kinda of a dumb question, but I noticed that when its first spooling up, the output shaft is not turning. Is there some sort of centrifugal clutch between the output shaft and the engine?
It's got a free-power turbine, which is not connected to the same shaft as the gas producer. The power turbine basically acts like a wind mill, which is spun by the gasses produced by the main engine. That is then geared down to the output shaft. It wont spin until there is enough air flowing to spin it over, hence why the output shaft doesn't turn right away. Exact same thing on helicopters.
Thank you sir. I have often wondered why a turbine helicopters' rotors did not turn during the first few seconds of start up. I think I have observed the same thing on turbo props.
No problem! Yes you are correct on both accounts. There will be a lag while the power turbine spools up. I actually think it's pretty cool to hear that high whine of the turbine, and see the output slowly start to spin up, knowing how much power is behind it.
A turboshaft engine produces the same amount of exhaust gasses as a turbojet engine, however, the difference is the velocity of the exhaust gasses in a turboshaft engine are slowed dramatically by the free-power turbine & diffuser extracting that power to turn the output shaft (which is geared down). There is still SOME residual thrust, but it is negligent.
"pool" horse power has no turbine related meaning... where'd you see that? If you mean "shaft" horsepower, then see the question/answer a few comments below.
Its got a cool sound to it. I wonder how great it would be if you made it run a vehicle; not a car or truck or anything of that size but like a golf cart ROFL.
That is correct... this unit was paired with another engine and they were coupled together with a combining gear-box to drive an electrical generator for U.S. Naval mind sweeping equipment.
They are actually more efficient than piston engines, at least when working at steady rpm, which makes them ideal for helicopters and airplanes, but not for vehicles.
I agree douro20. Usually gasturbines are not better then piston engines in terms of thermodynamic efficiency. but their power/footprint or power/weight ratio is much higher than piston engines so thats why we see them on aircrafts not on ground vehicles. not to mention the reliability due to less moving parts...
Hi, yes, Boeing did make engines. The smallest amount of research will show you that. They actually made the first turbine engine that powered a helicopter (original Boeing 502)
From Boeing's website: "Boeing was a major producer of small turbine engines during the 1950s and 1960s. The engines represented one of the company's major efforts to expand its product base beyond military aircraft after World War II."
