N-4K arrowhead SSTO, no rapiers and it can go to the mun and back!

[Screeno]

Edit: works perfectly fine in 1.0.2 aero!

Greetings kerbalnauts! may i present to you, the N-4K Arrowhead SSTO spaceplane! no rapiers, and it can get to the mun and back with fuel to spare if you refuel it in lko!

Stats:

Parts: 102

Weight wet/dry: 64.5/38.1 metric tons

Engines: 6 turbojets (offset tooled together), 2 aerospikes (offset into the turbojets), 3 nukes, and 6 vernors for vacuum takeoff

Crew: 2 pilots 4 passengers

How to fly:

First, use 5 to make sure the vernors are off, you don't need them yet and they will waste fuel now.

2, cut thrust, and stage, this turns on all engines, press 2 and 3 to turn off rockets for now.

3, full throttle, pitch up and take off, and pitch up to 45 degrees.

4, when you are at 5000 m up pitch down to 30 degrees, now you're going supersonic.

5, at 10000m pitch down to 20 degrees, and you'll really start to go fast!

6, at 15000m pitch down to 15 degrees, remain this way for now. you will be cooking properly by now!

7, at 20000m press 3 to turn on nukes, this will assist the turbojets as they weaken, dont need aerospikes yet.

8, at 24000m the jets assisted by the nukes will not be enough, so press 2 to activate aerospikes

9, remain at your 15 degree pitch while you're in the aerospike + nuke mode

10, when the onboard oxidiser runs out, you should have got to just over 1800m/s. the nukes will do the rest of the work now.

11. pitch down more to horison the closer to orbital speed you go, eventually at 40000m its best to be flat on the horison to get the most speed.

12. apoapis goes above atmosphere, but be wary, there is a long coasting phase where you are still in the atmosphere until your apoapsis, so keep the nukes at a low thrust just to counteract the drag, past 60 km you wont nedd to though.

13, circularise!

14, if you want to go to the mun and back, you now need to refuel at a station in low kerbin orbit. fill up all the tanks with liquid fuel, and put a small amount of oxidiser, about 200 units, into the oxidiser tanks, this is for the vernors.

15, standard mun transfer and orbital insertion.

16, mun landing is done in the optimal method to save a lot of fuel. perfect example shown here:

17, to take off from the mun , first use 5 to make sure the vernors are on. turn off the brakes if you have them on, then go full throttle, at exactly the same time, press K to make the vernors fire, you only need to do this for a few seconds, this will make the craft lift off and pitch up, so you dont smash back into the ground again, the just turn the vernors back off, pitch up and just continue to orbit.

18, get into mun orbit and burn to return to kerbin, make periapsis 20km

19, pump remaining fuel into the FLT-800 tanks evenly, and if therer is more liquidfuel than the flt800 can carry put that in the big s wing strakes, evenly. doing this ensures that the center of lift and center of mass are aligned correctly for stable flight.

20, reenter with a 45 degree from prograde angle off attack and you will slow down enough and you wil not explode use airbrakes if you think it's to fast and hot.

21, good thing there is plenty of liquidfuel left, as you may need this to use the jest, to assist your landing glide.

Good luck with it and have fun!

tell me if it still gets to orbit in 1.0.2.

(Warning! in my game i'm playing with an aerodynamics config numbers exactly between that of 1.0 and 1.0.2 because i hate the 1.0.2 too much drag thing, and i thought 1.0 was fun but don't want to stray to far from "stock" personally i think squad should implement this best of both worlds config in the next patch as it would please many.* i have not tested this in the 1.0.2 configs, do so at your own risk!!!* lol)

.... *leaves*

EDIT : Now that this has been tested, Great work actually

Let's not be too trigger-happy on the dismissal. Can someone (perhaps OP) try this in stock 1.0.2 and see if it still works?

I like your spirit, We'll give this a go

[Roflcopterkklol]

It still gets to orbit fine in 1.0.2, im sure that is enough fuel to go to the mun and back also, flies well at all stages of the atmosphere as well, idk why you arent using 1.0.2 OP you may as well be

[Screeno]

Cool it works in 1.0.2? Thankyou so much for testing! + rep

So you should move to 1.0.2

Aeros gonna be rebalemce in a few days when 1.0.3 comes out mind you

Again?? Ah dang, we're gonna need to scrap and redo everything again

[Screeno]

I don't think so, they won't be increasing drag anymore haha, what I think they will do hopefully is valence the aero to be a happy mix between 1.0 and 1.2.0 . That would mean everything would still work, perhaps better than before!

[problemecium]

I wouldn't count on them changing it back to more like 1.0.1 - the atmosphere in 1.0.1 was actually "too" thin according to SQUAD, as there was a bug that made drag not apply to parts where it should.

They better not make it worse lol.. my craft are all already getting into the 300+ part range to be SSTO's, it just takes such huge craft these days, i mean i have a nvidia geforce 970 but it aint enough haha
