I present Boaty McBoatface

A missile/launch boat that was based on, but not a replica of, the USS Freedom.

  Reveal hidden contents

She is 50 meters long, and consists of a measly 559 parts. It has a full helipad(for VTOLS obviously) and a large hangar. It also has wheesley's prositioned strategically around the ship so that it can traverse left, right, rotate clockwise, and counterclockwise. Plus the triple goliath propulsion system that can bring the top speed up to 32 m/s. 

BD hasnt been updated so i have yet to arm her, but in the future there will a couple cannons and AA guns and the like. Her main armament will be whatever sort of aircraft i can fit into that hangar.

I also need to figure out some sort of hangar door. Will be difficult, gimme some suggestions.

If it lags. Then download Ubio-Welding Mod! It welds parts into ONE part!

Have a series of panels linked together by hinges.

Then at the bottom joint, have 2 I-beams on hinges, and have the I-beams (or something low friction) running through 2 columns with a little space in between for the i-beam(or whatever) to run through like a track, with docking ports at the top and bottom. Propelled upwards by junos, downwards by gravity.

That kinda didnt make any sense. Either way i gave up on the door idea.

The welding mod breaks your game if you have anything on it that does stuff. Like engines, landing gear, fuel tanks, lights, science equipment. Etc. Plus i want to be able to break it apart. I love exploding this boat, it impervious to everything except @Columbia's 757 and @Raptor9's Atlas.

Can anyone tell me why the Keel of my boat keeps exploding? I dont understand. Everything is strutted to it and it ends up ruining the ship.

My best guess is still stress from the weight of the panels, some may be still not be secure enough, although I am sure you have lots of struts I use hundreds of struts also. You could also try removing what looks like crew quarters, those look blended into the steel panels, this to could be causing stress.

I've noticed that too much autostrutting to far off parts can cause vibration and then disintegration.  I try to utilize the "Grandparent Part" autostrut function rather than the "Root Part" or "Heaviest Part".

@Raptor9 @Castille7 I replaced the ore tanks with Mk3 fuel tanks and that seemed to do the trick. I guess ore tanks are just really weak.

Also, Have you guys found that anything over around the 500 part mark causes a excrementsE load of lag? I was sailing just the hull(430 parts) and i had around 35 - 45 FPS but as soon as i stuck on the superstructure FPS dropped to around 5. I dont really understand. That happened with the other ship too.

I don't think there is any hard number that causes the lag to go up significantly, but I could be wrong.  Also, what part number at which lag becomes noticeable is going to be subjective to each person based on their computer's hardware.

But then again, I'm the furthest thing from a computer expert that you can get.

I agree that computers to have more issues lagging rather than KSP lagging. I find my computer lags when others seem to be doing fine with many parts.

I will keep an eye out for this and let you know if I experience this

[XB-70A]

Actually working on a full stock kind-of Pegasus-XL launcher called Chrysaor. There is still some work to do but the main targets are achieved.

The launcher got more than a year old now but the carrier trying to be the Stargazer TriStar is totally new (and hideous).

The payload was a useless ComSat of 1.3 tons only put into orbit to confirm the design.

Strangely Chrysaor is so stable that it's the sole craft with the Hecate shuttle that I flew manually... really, once its dropped you just have to flare a bit and stabilize enough then ignitiate the first stage SRB, wait a bit to get speed then start the climb easily. Surprising.

Yeah, yeah i know how computers work. I'm saying before 1.2.2 i would get decent FPS up to 900 parts before the lag became unbearable and now that number is down to around 500. Just thought it was weird and annoying.

That should not be happening.. If you can face it try reinstalling KSP, back up all saves and craft before!

Designing launch vehicles for my upcoming 6.4x scale New Horizons playthrough. New Horizons still isn't out for 1.2.x yet, but Sigma Dimensions is, so I've upscaled Kerbin already to work on getting things to orbit.

I found a comment from a while ago that suggested that the required delta-v to reach Kerbin orbit in 6.4x scale is about 7500m/s, so I designed the above rocket to provide that for a 1.5 tonne payload.

Full flight profile is below.

Spoiler

Liftoff successful. Despite being influenced by the Russian R-7 rocket, the core engine on this rocket is not ignited until the boosters are separated.

There is no throttle limiting on this vehicle, and acceleration is quite high before booster separation.

Booster cutoff and separation, and main engine ignition. The boosters separate in a perfect Korolev cross.

Ascent continues nominally. This stage burns for quite a while, and cuts off almost exactly as the intended 152km apoapsis is reached.

Stage separation and fairing separation.

Upper stage ignition.

Upper stage cutoff as intended apoapsis is reached.

Circularization is successful. The upper stage still has a lot of delta-v left, so the launch vehicle is potentially capable of transporting a greater payload mass to orbit.

Once in orbit, the upper stage still had about 1200m/s remaining. This is good, because it means that orbit can be achieved with less delta-v than anticipated, which will make launch vehicles cheaper for career mode applications.

Ive done that. Twice. I even installed onto a flashdrive to see if it would help but nope. 

 

Have you ever made a autocannon?

Thanks KA. I was so tempted to rebuild a TriStar as the Goliath now is available but I haven't forget what I promised. These screenshot were taken during yesterday morning on the second offcial flight test (unoffcially it was during the 3rd and 5th, when I got the battery problem...) but right now I am and will be trapped at my shop on 09:00 to 22:00 everyday until Sunday (end of the year).

But a promise is a promise and I should be able to share it on KerbalX on Monday.

Some other screenshots taken during these flights for waiting

Awesome! Looking forward to flying it.

Testing a Fifth Wheel right now, it's been very delicate but working well. Made a Gooseneck Trailer and a Fuel Trailer for now.

Is it a truck party? Because I also have one from the last version carrying a stock cruise missile, which still works.

Diesel Rig 7-18
Update 12-17-2016

I was having trouble with the first design of the Fifth Wheel Connection, it was breaking too easily and the Trailers were often jumping off giving me a runaway Trailer which was actually fun at times. The new design is using Solar Panels and is now stronger and holding the Trailers better. I now have a Gooseneck Trailer, a Dry Van Trailer and a Fuel Tank Trailer, not sure if I will add another Trailer if I do it will be a Boat Trailer with a Boat to launch.

I'm still working on those Saturn replicas, but since I really don't want to have to start working on the LEM right away, I've started experimenting with a breech-loading artillery piece.

The gun is fixed in place, since it's just a test rig to determine how easy (or hard) it may be to get something like this working properly.

The charge is just a small SRB, but most of the fuel has been removed, so it only fires for a second or two, thus lowering the chance of incinerating the shot or tearing the piece apart.

I may have to upgrade to a bigger size, since the bullet doesn't gain very much velocity and thus fails to attain significant range. Also, it tends to break up during flight, so I need to find a way to either improve the current round's structural integrity or a single part that will be able to take the place of my current setup.

After firing, the shell casing is ejected and knocked out of the way.

The legs then retract, clearing the way for the next round to be loaded (I have yet to figure out how I could load a second round)

 

EDIT: I've got a smaller bullet, but it still doesn't get very much range, and it isn't very stable in flight.

This shot went pretty far, but it's only because the bullet hit the ground and bounced a few times (which still caused it to break up).

Just trying to get back into my building groove here, might try and expand on these WIPs later on...

^Though I plan on making this one SSTO if possible.

I used to run with the standard setting of the physics delta-t timer, 0.04. Since I run at 0.08 I get green numbers most of the time, at the expense of some FPS. I have an old GFX card (2008) so it really helps my system.

[Azimech]

Decided to give my own real world car, a Citroën BX GT 1985, a chance to compete in the Dakar 2017. This is a stripped down version without the panels. Performance is reasonable with two Juno's, its top speed is 75.6m/s. Engines in the front, Boost Flaps in the rear. It's easy to drive and can handle some jumps without breaking the wheels, due to the high damper setting a terrain seam sometimes gives it a strong jolt. But hey, I wanted it to handle like the real one.

Those vernors can handle quite some stress so a good material for building car frames, if a little heavy. Best of all: no struts were harmed during the building of this car, it doesn't have any.

 

[andrew123]

Breech loading 460 / 480 mm canon, with the breech loading system almost complete. For the canon shell casings, I'm going to try and make them disintegrating. 

As for the elevation mechanism, I'm probably going to have to use jet assisted SAS gears. @Azimech, I might have to ask for your input on this. 

 

Otherwise, it seems that this specific version of KSP crashes every time I try to load the canon. I'll play around with it a bit and see what's up, though a smaller design I've built before never had these issues.

 

The actual specs of the Yamato's primary guns are impressive.
