aight will do thanks

"More blue water." water doesn't appear at all now I just get the texture of the seabed. Uhhg.

Well I mean if you up-gear it enough you will generate more speed out of a smaller engine and vice-versa. Like, attach a big gear directly to your engine and mesh it with a tiny gear. You will get more speed out of the engine now. Considering how aircraft engines don't really need to generate very much torque, like a car, a small low powered engine would work fine with up-gearing. But gears don't really work too well in KSP at high speed so.

uhuh......uhuh...... ya I know what some of those words mean.

yee

Ya that's in FAR. Where turboprops don't work.

I have never gotten a Juno powered aircraft above Mach 1 and I am 90% certain thrust drops off significantly at speeds greater than Mach 1. Try it yourself. I once made a airplane under a ton powered by 2 Juno's and it reached Mach 0.95 but wouldn't go any faster.

Our engines produce a lot more horsepower but they are also A LOT bigger and heavier. And a lot more inefficient and have lower RPM. So there really is no performance difference when we are talking about top speed. Also. As you know, Juno's can't really break the sound barrier so as long as we use them in our engines we are pretty much limited to subsonic regardless of RPM. If we go supersonic the thrust from the Juno's will just drop off past unusable levels.

Again, I have no clue how KOS works or how to write a script so I'm just going off what your saying lol. Check this out. Jumbo liner: 237 m/s = 530mph Gremlin Mk3: 245 m/s = 548mph pusher prop thing: 257 m/s = 574 mph Tu-114(official fastest propeller powered aircraft): 241 m/s = 541 mph Lockheed XFV(unofficial fastest propeller powered aircraft): 259 m/s = 580 mph So if KSP physics is anything close to IRL physics we are literally at the almost the fastest we can go. The Republic XF-84H was a proposed supersonic prop powered plane that was actually built. But it never reached it's design speed and only went 520 mph because of bad design and getting a plane to pass even close to supersonic is ridiculously inefficient and difficult anyway. However it was (obviously) equipped with a supersonic prop that looks cool as ridiculous and awesome at the same time. It is also the unofficial loudest aircraft ever built. Being louder than top fuel dragsters. The plane was so loud in fact that it could be heard from 25 miles away just at idle thrust because the outer edges of the prop spun at supersonic speeds. People were physically incapacitated and disabled by the noise.

Hmm. Ya that would definitely work. But since I have literally no idea where to even start with KOS I would hope you could manage to write something like that. I mean, it doesn't seem that hard. Like, if angular velocity exceeds 50 rad/s increase prop pitch. If angular velocity drops below 48 rad/s decrease prop pitch. If it is written in that format I would assume it would bounce between 50 and 48 rad/s and not really stabilize. Also, what about take off and landing? I would assume KOS would not know the difference between takeoff and a cruising speed run so it would try to decrease prop pitch beyond a usable level for acceleration while your still on the ground and cause bad things to happen. You said your jumbo liner was designed for endurance? Why didn't you enter it into my endurance challenge? After all that's where this whole conversation started.

That's why I was experimenting with the Free Moving Docking washer. But alas, VOID doesn't display RPM in that configuration and I think it is limited to around 20 rad/s anyway. I wish someone would write a quick plugin that allowed you to control aspects of other craft close by without having to switch over to it.

Nice! I believe this is the fastest one yet besides my own plane. I have this challenge personally on the side while I try to break records for turboprop aircraft. I am currently the second fastest turboprop builder as well XD. I had the record for a solid 12 hours before Azimech came out of whatever cave he'd been in for the last weekish and revealed something only 17 m/s faster than me! We are now less than 100m/s from the sound barrier.

Last night before i went to sleep i did a complete airframe re-design and I shaved 10 tons off the weight. It now weighs 47 tons. Which is just 1 ton heavier than the Gremlin Mk2. I didn't have the time to try another speed run but it should be faster. by a little bit. Side note. I think Pilot Assistant can't calibrate correctly bellow 200 meters. So if you are ever going to do speed runs below that altitude you have to make sure you turn on PA above 200 meters and then descend from there. Or PA will fly your plane into the ocean or climb at such a high AOA you stall.

I have to drive for 8 hours tomorrow so I'm gonna get some sleep. I might do some work later tomorrow but I might just go straight to bed lol. Will also check out Azimech's plane at a later date.

The crappy internet in this hotel doesn't load pictures so I don't know what your plane looks like. But i'm assuming it is pretty cool.

That's what I've been doing since I started making turboprops lol. I mean, what was your plane designated as?

Record = broken again This time it is 100% my design and the engine doesn't explode unless you really want it too. RPM maxes out at 50.5 rad/s. It doesn't explode if you try to exceed that RPM. It just stops increasing. The plane would have kept accelerating probably past 250m/s if pilot assistant hadn't flown it into the ocean. I was trying to recover it so I didn't get a screenshot of the exact speed when it crashed but you can see 245m/s in the flight log. I got a legit screenshot of 242m/s which is faster than the record of 237m/s anyway.

I copied the exact craft over to my slower, grosser, desktop and it works flawlessly. Except for the extra lag. So I have no idea whats wrong with my laptop but I guess for the remainder of my tests of this plane I will be on my desktop.

If you angle them backward you will have thrust provided from the blowers rather than the actual engine. If you angle them forward you will just have thrust from the blowers working to slow the plane down. I am so mad. My game just s h I t itself today and my plane no longer works. I restarted my game and my PC several times to no avail. FUUUUUUUUUU I guess I will just have to START OVER why is this game the way it is

Disaster has struck. I launched KSP as normal every day to work on the plane. I have changed nothing since yesterday and all the settings are the same. Right when I launch I get the "jiggly-prop effect" on my entire aircraft. If I can manage to takeoff without the jiggleyness happening it just explodes for seemingly no reason right after takeoff at different speeds and RPM every time. UUHHHG

ATM i'm trying to produce a engine that can run sustainably at 50+ rad/s and beat the current speed record. Which is now 237 m/s. So far I am doing pretty good from starting completely from scratch.

Some of my original designs from last year used that part and were pretty unsuccessful. Only reaching about 50m/s on a test cart. It was me who tried them. I briefly went over why they can't be used for multiple reasons a few pages back. A few pages back I posted pics of my panther powered engine. It had a decent max RPM of around 38 rad/s with 16 panthers all on full afterburner. However it went through fuel far to fast and overheated my atmosphere thingy vains so I had to switch to structural panels which also overheated eventually. On the upside though I got much better FPS because of the low part count. I converted that exact engine into the Juno powered engine I just showed you yesterday. Which has been extremely powerful and reliable. So my summary is, panther powered engines will always be outperformed in power and efficiency by Juno powered engines. No matter what design or implementation you use them for, you will always be able to build a Juno powered version that produces more power and is more reliable.

Wow nice! The official record is 235 m/s. So, in yours and Azimech's runs, your engine actually exploded. But when i did my run, (230 m/s) the plane actually just stopped accelerating. Which is cool. I think i can mess with the prop pitch for more speed but i'll leave that until tomorrow. I have got to get some sleep goodnight

Well you definitely beat the record for engine out top speed I guess. Your endurance is obviously doubled as well, so i challenge you to beat the real life engine out endurance record of 177 minutes set by a Boeing 777. Just use pilot assistant to set your heading and bank level and go eat lunch or something.

The thing with Juno's is that they perform a lot better the closer you are to sea level. So when ever i do my speed runs i try to get as low as i can safely for maximum thrust out of all the Junos. On the downside though, being closer to sea level means more soupy air and more drag. Causing your plane to slow down. Can someone calculate a formula for the optimal altitude based on blower count, blower efficiency, blower throttle curve(i think), plane weight, and airframe design (drag created by airframe itself) Can your plane continue on one engine?
