Jak Airways: Turbo Shaft Engine Devision.


Jakalth

Recommended Posts

Jak Airways is proud to present our line of Turbo Shaft Engines, under license from Azimech and 77 Industries. We have several differing designs of engines to fit your needs. From big too small, we have them all.

Shaker: Radial Engine Line

We have a selection of 5 different radial turbo shaft engines to suit your needs. They start with tiny and go onwards to absurd. All the shaker radial engines feature 0 too minimal turbine blade expansion, meaning blade knocking is nearly a thing of the past.

"Mini Shaker" 4-cylinder radial:

4cylradialenginetop_zpsvrfvpvzx.jpg4cylradialengineside_zps2mmdhamu.jpg

This little 4-cylinder radial engine may be small, but it is also not big. What it lacks in size, it makes up for in sheer; "This should work if we spin it fast enough". This little engine is well suited for lite duty use on small craft or as auxiliary engines to help stabilize larger crafts. With its patented "We don't need more then 4" attitude, it is sure to find a home in your drone craft garage.

Part count: 84

Weight: 10.8 tons

30 seconds of fuel included at no cost.

"Shaker Light" 6-cylinder radial:

6cylradialengine_zps3ernih66.jpg6cylradialengineside_zpsfgnrftsg.jpg

The Shaker Light is a light duty 6 cylinder radial engine designed to not be as small as a 4 cylinder radial engine. This "Lets make it bigger then the mini." attitude has produced a fairly reliable and moderately powerful engine that is suitable for many differing uses. It is not recommended to run this engine without having a load on the drive shaft or "Unintended separation" may occur due to "Over speeding". Propeller not included...

Part count: 119

Weight: 17.8 tons

Includes 5 minutes worth of fuel, totally free(No we did not simply forget to drain it first, it was intentional.. honest.)

"Shaker" 8-cylinder radial:

The standard Shaker engine has gone through some revisions, it now boasts a "less parts sticking out the sides" improvement over the previous version pictured on the right. A few little tweaks and tucks have made the engine slightly smaller as well. With it's 8 cylinders, it is 2 more cylinders more powerful then the shaker light, and double the power of the shaker mini. This is a much bigger engine all around then it's smaller brothers. With this size comes more durability from extra struts and reinforcements. This engine is well suited as a main rotor engine for heavy lift helicopters and for use in large craft of all sorts. Propeller not included...

Part count: 166

Weight: 23.2 tons

comes with about 3 minutes of fuel at no cost.(see told you it was intentional.)

"Double Shaker" 12-cylinder radial:

12cyldouble6engine_zpsd0z9lsft.jpg12cyldouble6engineside_zpst4tctx56.jpg

Boasting 12 cylinders and a breakthrough idea of; "lets put cylinders on BOTH sides of the bearing", this big engine is a powerhouse. This engine was a complete redesign, from scratch, and not just 2 shaker lights slapped together. Honest. This engine is surprisingly small for the amount of power it can produce making it well suited as a primary engine for heavy aircraft of all sizes. The revolutionary "cylinders on both sides" approach has yielded an engine that also runs surprisingly smooth. But the addition of extra cylinders has slightly increased its weight and parts count. But if you have the need of a truly big engine, look no further. Or maybe you will? Hmmm, this is probably the biggest engine we'll make, you can stop typing now. I said you can stop now... Hay! propeller not included...

Part count: 169

Weight: 26.5 tons

2 minutes of fuel included for a limited time(he did what? again? Kervin, get over here now!)

"Monster" 16-cylinder radial:

monster16radialtop_zps5xnasymh.jpg

We thought it couldn't be done. We thought we had made the biggest there will ever be. We were wrong! Kervin did it anyways. "I bet I could make one even bigger." he said. We all doubted him and laughed at the silly notion. An engine even bigger then the double 6. HAH! But then he went off and made this Monster. And now we have to try and get rid of... err... make this engine available for purchase. This engine is a true monster, following the; "lets put cylinders on both sides" logic of the big 12 cylinder. Only this time, using the 8 cylinder layout. He's insane I tells ya! This engine is far too powerful for any sane kerbal to use. Without some weight on the rotor, it will easily tear its self apart. But with this power comes great responsibility... And the ability to spin true HUGE, Monstrous even, rotors. This thing laughs at MK3 parts like they were mere tinker toys, and burns the fuel to prove it.

Part count: 254

Weight: 35.3 tons

level of insanity needed to use this engine: Extreme

comes with 30 seconds of fuel at no... (that does it... Kervin, your fired!)

I'm just surprised people have started building them again.

It was a long time ago that the first ones where built. People stopped making them because they are kinda useless ingame..

They are very fun to build so I can kind of understand the interest again. I guess its new forum users picking up where the others left off.

There will be lots more after the 1.0 update. What with the new small landing gear. Sadly they will be as unwieldy as they are now.

Jets and rocket on helicopter blades are useless, yes. This is just the beginning, KSP might evolve (or a spin-off might be created) more focused on engineering. It could be an even more inventive learning tool than it already is now. Turbines are nice but I already have designs in my head for gearboxes, I've already demonstrated a working clutch and brake, I've experimented with cyclic/collective and even had a chain drive (sadly KSP/Unity seem very poor with respecting colliders).

In the literal meaning of the word. They are fun to pootle around the KSC in but not much else.

I see what you mean but any helicopter type vehicle isn't going to match the speeds of a jet or rocket. I will upload the Chinook soon and encourage you to give it a fly. Honest opinions are welcome but this one has proper flight capabilities. It can do barrel rolls and loop the loops and I am going to test to see if it has the range to get to the Island runway. It is limited to a horizontal speed of 50 m/s.

It made it to the Runway Island! Flight time was about 15 mins and it didn't even use half of its fuel. Here is the epic journey. Mechjeb was used for information purposes only and never used as an autopilot.

Here is the craft file download.

This uses Jakalth's 8 cylinder "Shaker" engine with some very minor tweaks, (re-did a few struts and remounted the engines). The craft file is 447 parts but can probably be reduced with some work. Pitch and yaw are a bit sluggish but roll is very sensitive. This is good as it makes landing easier. Do not retract the gear as it holds the rotors in place. Brakes have been disabled on the wheels used for the bearings so feel free to use brakes as and when for the undercarriage. Hotkey 1 toggles the jets which is useful for when you touch down.

Okey doke, will try it out and get back to you.

Nice! When I have the time I'm gonna test it!

By the way, brakes on the rotor bearing could be used to slow down ascent, if used with pulse width modulation. I use it to slow down my propeller on my planes, this way it produces more drag and slows the plane down quicker when landing.

This is true but my craft tends to drop pretty quickly when the throttle is cut so I reserved brakes for the landing wheels only.

Quick question as to the principle of operation...

I have one (on a modded install, but still using stock parts) that in my head, should work. The bearing assembly works excellently and weighs like 500 kg total, and if I just bolt on a few reaction wheels, the drive shaft spins up to ludicrously fast speeds. I've got the jets aimed somewhat off center, but for some reason, they don't seem to spin the prop at all.

Alright, tested yours. It appears my mods are playing with the way engine exhaust effects parts... for some reason.

Sweet! I'm testing to see if it can get to the Island runway at the moment. I haven't tested its carrying capabilities yet.

Ok I flew it. I am impressed! It was easy to fly but very slow and cumbersome to manuver. Once she settles down she was rock solid. If a little slow. I could only get around 40-50m/s out of her so I gave up trying to reach the second airport and did a loop the loop instead! See below.

She was easy enough to land too. I love the theather of flying something like this but they are always too cumbersome to be really useful.

Overall a very good job man! I had a lot of fun.

Wow, thank you Majorjim. Considering your expertise when it comes to all things aeronautical I valued your input there. You were brave to do a loop the loop at only 700 meters! I have made a more powerful version however over 70 m/s there is a danger the rotor blades hit each other due to the forward swinging blades getting more lift and the shaft bending too much.

- - - Updated - - -

Got my engine working... My lord this thing generates a lot of torque. Taking off is a nightmare, and flying is worse. Still got to around 70 m/s ASL.

Post some pics if you can! It would be great to see it.

You could always pull the engines and fuel tanks out of the radial bearing and slap about 4-6 asas modules on top, with enough nuke gens to power them. Then just add a drone core and some blades and it should be able to fly. But the helicopter would need to be ultra light weight, or you'd have to "cheat" by using rotors with canards on the end of them causing them to infiniglide. otherwise asas modules alone have a bit less power then the turbine like effect the basic jet engines cause.

I want to try this but use ASAS alone to power the rotors - that way there's no smoke. Of course I see the advantages of having throttle on the chopper itself. So you've probably got the right idea. Carry on.

I suggest looking at my old electric helicopter concept.

It is crude compared to newer models I have made but could sure use improvement.

Matter of time before the devs kill low-altitude smoke on the jets. It's totally unrealistic anyway. I edited the basic jet config file so I don't have the smoke anymore and still have stock crafts.

The jets are heavy but the amount of torque and rotational speed a turbine provides can't be beat by any stock electric engine.
