[1.0.5] Fun with Goliath Engines


Recommended Posts

After reading through the first craft of 1.0.5 thread, I know I'm not the only person who had this idea the instant they saw the new engines:

Essentially, instead of attaching the goliath engine to a wing or fuselage, the goliath engine [i]is[/i] the fuselage, and hilarity ensues. The sheer power of the engine yields sea level speeds of >500 m/s before overheating destroys the engine (although the new hydrodynamics model allows the cockpit to land safely in the water) while the high twr allows for superb maneuverability. EDIT: turns out this thing is even capable of water landings thanks to the high lift/weight ratio.

But come on, just one engine isn't enough fun:
How about two?

Or three?

Or five?

All of these are speed limited by the heat capacity of the goliath engines, a problem a few radiator panels might solve, although the maneuverability severely decreases with each iteration of engines on engines.


What else have y'all made?

Posted this some time ago in a different thread, but... much the same thought you had :)

Well, you can push the craft too full power with radiators attached. yes. But it does become a hindrance on it's top speed if you add too many too the craft, 8 for example.

It tops off at 340m/s but never overheats, at low altitude, no matter how long you push the craft. Gotta love the working radiators. btw: yeah, I did simply copy the design you had, using the picture. It is YOUR craft, Ojimak.

As for playing around with my own designs. How about a vtol powered by clusters of Goliaths? Yes, I said Clusters of them.

Can it vtol? yes.
Can it fly forwards? yes, by tilting.
Is it fast? well... (insert long explanation here) no.
Can it land? ???(untested actually, other then a water landing that wasn't pretty)
Dues it make bread, dice carrots, and grill meat? no...
Can it aircraft? .........

Nice to see someone taking the goliath spam to the max. What's the flighttime like with that many engines? Also, are you sure it can't grill meat? Those engines have a lot of oomph.

About the single engine version, I feel like adding radiators may prevent overheating, but at 340 m/s I don't think overheating was really even a problem, so...yeah, maybe some creative clipping of a radiator into a storage bay would reduce the potential for overheating without increasing the drag so much (non-cooled version easily pushed to 600 m/s seconds before exploding), but I haven't read up at all on how overheat mechanics work, so idk for sure. If for some inexplicable reason you want to work with the version I used, [url=http://www./download/31vp0o6peilp6i8/Goliath_Mk1.craft]here it is (mediafire).[/url] I don't think there was anything on the one engine version not shown in the picture, although I know that the three engine version required disabling roll for the rudders to prevent some off-center control issues.

@neamerjell @cbplayer2012
Yeah, both the GeeBee and basking sharks came to mind when I made it, especially since the fins on the engine look somewhat like the stripe things in the basking shark's mouth (with some creative interpretation aka mental conversion of radial lines into secants)

-Ojimak. I'm thinking the next stage of this insanity should be to make a craft that flies only with the thrust reversers of goliath engines (and of course adheres to the minimal fuselage rule)

I wanted to take the goliath into space, just because. I abused the new ramp parts to create a sort of giant MK3 air intake and close it when approaching supersonic speeds to prevent it from melting. The goliath has just enough power to take off without any other engines but needs them when surpassing 700m. The goliath reverse thrust came real handy when landing after descending from orbit. Aerobraking took real long though.

That machine can stay in the air for at least [FONT=comic sans ms][SIZE=1]15 minutes. Possibly longer[/SIZE].[/FONT](that's an incorrect statement... after some testing at full throttle, it's closer to 45+ minutes.) The goliaths may be monsters, but they are beautifully efficient. And no, it can not grill meat. The goliaths produce little heat on their own due to being high bypass engines. And they pretty much just blow the meat around instead of cooking it...

I'll try using less radiators and see if I can clean up the aerodynamics a bit, on the single engine speeder. But the radiators seem to produce a bit of drag so I doubt it'll break 500m/s with any on the craft, unless I can hide them from the aerodynamics behind something else, like the engine.

:edit: Even placing the radiators behind the engine, out of the aerodynamics, the craft still can't push past 380m/s. Guess the mass has more to do with it then the drag. Also, past 350m/s even 8 large radiator panels are not enough to cool the goliath.

[quote name='Red Dwarf']Aww man, is that how many Goliaths it took to get that craft off the ground? Welp, there go my plans for a flying aircraft carrier...[/QUOTE]

No, It'll take off with less then that many. Probably as few as 4, maybe even only 3. But I was making the clusters for something a lot bigger and wanted to test them.... So built the upsized Sky Hopper. With the 9 engines, it accelerates quite quickly and can move pretty fast. Ok, fast is a bit misleading. around 200m/s.

:edit: confirmed. replacing the 3 triple goliath clusters with just 3 single engines and it still flies. So yeah, it's doable with far less engines. it's speed is dropped from 200m/s to a more stately 50m/s. but it's mass is also dropped from just shy of 100tons to a more respectable 68 tons.
