DST- Engines What type of coupling did you use? It seem like the turbofan is not directly on the shaft. Great work man. It looks beautiful! 😁👌

[@DSTEngines]

The fan is directly driven :)

[@putteslaintxtbks5166]

I've wondered why most RC Jet motors don't have air bypass or if they do, they're not fan driven (Iike it was just chance in the mounting). Nice job. In full size, I think as much as 60% of thrust is bypass.

[@frankhage1734]

@@DSTEngines Why do we hear the turbine spin up on startup while the fan is stationary? The compressor must be linked to the turbine, right? I think this must be dry humor :) I also noticed you had the engine mounted on spring loaded rails. Can you reveal static thrust measurements?

[@DSTEngines]

@@frankhage1734 big airliner engines: the fan spools up later top. Because the core engine must build up enough gas pressure to the low pressure turbine. Thats normal.

[@Taydrum]

Considering modern turbofans have much higher bypass ratios, FADEC fuel controls, controlled turbine casing clearances, and modern annular combustion chambers, this is fairly efficient

[@233kosta]

@@Taydrum I mean... even if you built it to the exact same standards as a commercial aircraft powerplant, it would never be anywhere near as efficient and that's purely down to compressor and turbine tip-to-case clearances. They _need_ to be a certain size, no matter how big the engine is. That said, engines used in airliners kinda cheat, at least with their turbine casings, where instead of super precise manufacturing, they use abradable seals cut into by the tips of the turbine blades (usually with an abrasive coating of their own). That's as tight as it could ever possibly get.

[@Lucentlens]

It *is* that though - but dressed up to look & act like the real thing. This isn’t some multi-compressor set-up - it’s a normal single-stage engine in there. But the moving front blades is a fantastic touch - but they can’t be directly connected - even Rolls Royce would struggle to come up with a blade ‘that big’ & spin at 140,000 RPM. In real plane engines, I think they only get to about 12,000 RPM - surprisingly ‘slow’. There will be some blow-by for sure - but the majority of that thrust that you can literally see, is from the engine nozzle.

[@billyost1479]

As a former Army helicopter turbine engine repairman, I will say... I am impressed. Turbine engines are mostly all the same. But much more complicated than a jet engine. Turbine engines have one shaft for the compressor turbine and one for the power turbine. Two completely separate yet related necessities. Jet engines are so much simpler, they don't deal in torque... just temperature and thrust. Turbine engines are where the efficiency is though, they waste much less of the heat energy.

[@DroneMee]

I assume you mean turbofan engines rather than turbine engines as all jet engines; turbojet, turboshaft(your helicopter), and turboprops are turbine engines as they harness the enegry of expanding gases via one or more turbines. As you stated the complicated portion of this engine is the dual concentric shafts running from a high and subsequent low pressure turbine to the compressor and finally the fan. What an awesome little machine!

[@chris1451]

A jet engine IS a turbine engine. I jet engine needs a turbine to drive the compressor. The turbofan, of which this is obviously has two shafts with a power turbine to turn the fan.

Couple of them on an ultralight could be really cool, appears to have the power and weight to be ideal

[@jesseespinosa9739]

But not fuel consumption. Itd be a short flight. Adding more fuel defeats the ultralight aspect.

[@Prototheria]

FAA Part 103 ultralights are limited to five gallons and the average ultralight can stay aloft for two to three hours. This thing by very rough estimate would burn through that in about an hour. Factoring in start up and taxi out and back from the active, you're probably going to get three or four laps around the pattern before you need to land, so forget about going anywhere. If you want to carry more fuel, it needs to be an experimental aircraft, and you'll need a turbine rating added to your full blown pilots license. Adding a second engine will require the same ratings you'd need for a business jet and at that point, if you have the money to throw at that kind of training, you're not going to be screwing around with an ultralight. Nice idea, but it won't ever happen.
