Lyneira Posted March 22, 2023 Share Posted March 22, 2023 (edited) Been working on a minimum-mass ssto spaceplane for a single kerbal since the release of patch one, lots aerodynamic stability issues and launch failures. It's meant to use the small "Whittle" jet engine to get up to about 10-11 KM and then to orbit on two "Spark" engines. I've had many attempts with different wing configurations and fuel amount, adding a pair of "Ant" engines to try and squeeze out just a bit more ISP during the last slow burn to orbit. Yesterday evening I finally managed to get one into orbit with a little over 300 m/s delta-v remaining! I don't have the exact specifications on hand right now, but it masses about 3.74 tons on takeoff. It's hard to overstate how much I appreciate the new procedural wings now, enabling small craft like this to have fully featured sets of control surfaces without adding a silly amount of mass. I am still looking to refine this design more, as well as tips on the best possible ascent profile, as it takes a bit to climb this craft to 11 km. I can post the craft in the spacecraft exchange with full specs if there's interest. Would this idea be worthwhile making into a challenge? The key points would be something like: Take one kerbal into LKO. Should have x amount of delta-v remaining in orbit. Return the craft and kerbal safely to Kerbin. Minimum possible mass. No staging or docking to perform its task. For the spaceplane category: Takes off horizontally from the runway, lands horizontally on the runway. For the freeform category: Launch from anywhere on Kerbin, can control its descent to return to its launch location from orbit. The deorbit burn should not require so much precision that it takes many save/load attempts to get it right. Above categories for both stock and modded.

JoeSchmuckatelli Posted March 22, 2023 Share Posted March 22, 2023 I got some really good critiques and advice about my prior attempt at a Gravity Turn from Streetwind - among others. Using his craft file and flight profile - I got an efficient Gravity Turn, with a single input on the D key. Fun! Quote Link to comment Share on other sites More sharing options...
Scarecrow71 Posted March 22, 2023 Share Posted March 22, 2023 Today I decided to try going through one of the challenges I created for KSP1 - the Historical Space Race. I've started a mission report for this, the link to which I'll give below. Starting from scratch, I recreated (the best I could) the R7 Semyorka ICBM flight test. I ran into a bug (falling through the water to the core of Kerbin) and the Kraken (ship vaporizing for no reason other than the Kraken seemed hungry today). But I got the first flight out of the way.

I posted my best of 660m/s as well and made a cool video. Beaky has one too.

BeakyBuzz Posted March 22, 2023 Share Posted March 22, 2023 My last 2 days was about the "Fastest under the bridge". Big thanks to @Socraticat - he made it very challenging every time! And as a closure for today, yet no one asked - but here is my video or the (current) record for the "Fastest under the bridge" : Quote Link to comment Share on other sites More sharing options...

Tapeta Posted March 23, 2023 Share Posted March 23, 2023 Yesterday I finished Weekly Challenge 4# (Jeb Level) and today I played again with planes. I used simple plane from Mk1 fuselage parts driven by one "Panther" engine running in dry mode. I compared different nosecone configurations and I compared maximum speed reached in altitude of 3000m. My results were: Mk3A Nose Cone ...................................................................................... 676 m/s Mk3A Nose Cone + SF-125 (structural fuselage) ........................ 704 m/s Mk3A Nose Cone + AE-FF125 (fairing) ........................................... 703 m/s TNC-01 ("XS" nose cone) + NSC 200 (small to tiny adapter) ... 702 m/s Tail Connector A ........................................................................................ 358 m/s AE-FF125 (fairing - pointy) ................................................................... 637 m/s AE-FF125 (fairing) ................................................................................... 635 m/s Mk3A Nose Cone + CBS-125 (cargo bay - short) ........................ 315 m/s Mk3A Nose Cone + CBL-125 (cargo bay - long) .......................... 697 m/s Spoiler Mk3A Nose Cone: Mk3A Nose Cone + SF-125 (structural fuselage): Mk3A Nose Cone + AE-FF125 (fairing): TNC-01 ("XS" nose cone) + NSC 200 (small to tiny adapter): Tail Connector A : AE-FF125 (fairing - pointy): AE-FF125 (fairing): Mk3A Nose Cone + CBS-125 (cargo bay - short): Mk3A Nose Cone + CBL-125 (cargo bay - long): Conclusion: Fairing by itself is good, Mk3A Nose Cone is better and longer nose build with combination of Mk3A Nose Cone + fuselage or fairing is best. Another very good choice is aerodynamically looking TNC-01 ("XS" nose cone) + NSC 200 (small to tiny adapter). From comparison of {Mk3A Nose Cone + CBS-125 (cargo bay - short)} vs {Mk3A Nose Cone + CBL-125 (cargo bay - long)} it seems that KSP2 thinks that longer things are more aerodynamic than short things - {cargo bay - short} caused much more drag than {cargo bay - long} . So that mean that you want to use long versions of cargo bays whenever possible. Quote Link to comment Share on other sites More sharing options...
The Aziz Posted March 23, 2023 Share Posted March 23, 2023 I made my way to Moho. Didn't land but made it (but only just) to extremely eccentric orbit. Some may remember when I said some unkind words about making it so boring I fully take that back upon seeing the planet up close, because gods this is pretty. Unlike anything I've ever seen.

Scarecrow71 Posted March 24, 2023 Share Posted March 24, 2023 In continuation of my Historical Space Race, I launched both Sputnik II and Vanguard I into orbit. I am particularly proud of how Vanguard I both looks AND how I was able to get it into the fairing. Quote Link to comment Share on other sites More sharing options...

The Aziz Posted March 25, 2023 Share Posted March 25, 2023 Landed on Ike. Lander flipped over. No worries, it was easy to fly away without losing a single part. Landed on Duna. Piece of cake. If you forget about 10 save reloads because of parachutes not cutting on touchdown, AGAIN Returned home. Ez. Quote Link to comment Share on other sites More sharing options...
Sspeter78 Posted March 25, 2023 Share Posted March 25, 2023 I flew to the Mun got into orbit and realized I had forgot a docking port on my lander. Figured, hell I’ll just land it and leave this Kerbal on the Mun. Well on descent I realized my landing gear was upside down. Flipped the module, hit the throttle, and crash landed in true Kerbal fashion. Ugh, will make corrections and try again today. Quote Link to comment Share on other sites More sharing options...

Only 69.97 kilometers to go... plus an ideal test for part count Can't build higher than VAB unless you launch separately. I know, I tried, it wouldn't let me slap anything beyond VAB floor when launch clamp went all the way to the roof. Also, enjoy your seconds per frame as you hit around 1000 parts. I know, I tried.

Lyneira Posted March 25, 2023 Share Posted March 25, 2023 (edited) A recreation of the Fer-de-Lance from Elite: Dangerous made in a couple hours. Making it look vaguely like the Elite version was tricky, hope it succeeded well enough. It flew surprisingly well and has just enough fuel to make it to orbit!

SimonTheSkink Posted March 26, 2023 Share Posted March 26, 2023 Finally completed my ship to explore Eeloo (and other planets as I see fit). It's designed to have replaceable hydrogen tanks and will shed empty ones along it's trip. Quote Link to comment Share on other sites More sharing options...
i dont know how to forum Posted March 26, 2023 Share Posted March 26, 2023 Been playing on my laptop up until now. Finally had the chance to test the game on my marginally better desktop today, and the performance difference is astounding. Flew a mint-chip flavored craft to both Mun orbit and Minmus orbit before returning to Kerbin. Experienced a very annoying maneuver bug but overall had a lot of fun.
