Hi @ShotgunNinja, Thanks again for Kerbalism, wouldn't play KSP without it! I just wanted to report that unless I'm mistaken it may be introducing some frame rate stuttering (I compared the game with and without it installed). This is not a degradation of the peak frame rate but rather a slight pause every few seconds. IMHO this could be due to the Garbage Collector having to reclaim too many short-lived objects (.NET GC performance, the Mono GC is slightly different but the same rules apply I think). I just had a very quick look at your code and I noticed that you seem to use the "+" operator on strings for instance. This is a source of a lot of such objects (strings are immutable and each "+" operator actually generates a single use new one) and may be related to this little issue? Just my two cents Cheers, David

@ShotgunNinja just dropping by to thank you for this masterpiece of yours!

Thanks for the much needed reminder! Speaking about "Citizen Mario's Dangerous Space Kart"... oops sorry wrong forum

Only one thing: whatever the chosen model, and for the sake of all the mods related to trajectory planning and flight guidance, SQUAD please document it!

Hello Gaiiden, As you know I can't talk about this app here as it doesn't meet the forum rules, so I'll post an answer on the blog ASAP (going for a 500km drive right now!). Cheers, David

Simple rules for interplanetary flights and working with the stock game (sorry I can't find the thread where I first saw these discussed): manned ships must carry at least 3 kerbals manned ships must carry 1 hitchiker module per 3 kerbals and per mission year rounded up (must be brought back to Kerbin) I generally rely on alexmoon's launch window planner to estimate the duration of the mission. Believe me this leads rather brutally to extra DV and ship complexity, and which increases with the distance flown!

Hi Pecan, For the record the PC used to build that thing is protected by a genuine and up-to-date KAV 14.0.0.4651 (current build). And I always check the files explicitely before release. Anyway you're definitely right that every one should always be very careful! Cheers, David

Thanks, no problem it is still there somewhere in the Forgotten Addons Belt, a bit further than Eeloo It's just more comfortable for me that way. Cheers, David

Hi, could you please delete this thread (already closed): http://forum.kerbalspaceprogram.com/threads/59899-NET-Ascent-Komputron-1-4-0-5-rocket-simulator-ascent-optimization-aerobraking and this other one (was already obsolete and should have been closed too) http://forum.kerbalspaceprogram.com/threads/62747-NET-AscentKomputron-Rocket-design-Ascent-optimizer-Aerobraking-reentry-planner Thanks

Hi, If that can help I worked on this app when facing the same question: Ascent Komputron - rocket simulator, ascent optimization, aerobraking It can simulate and optimize the trajectory of a rocket model taking into account thrust, gravity and drag (stock, not "FAR"). If the vessel can make it to orbit you get a reading of the total spent DeltaV together with the drag, gravity and steering losses. Cheers, David

Perfectly stated IMHO.

Did it a few times, but I had to write this first to make it! https://picasaweb.google.com/115863821253978853992/LaKerouseFlight

Hi All, Kerbal Petroleum and the Ascent Komputronics Society are happy to present the "KST Nabukodonosor" supertanker! KST Nabukodonosor "B"- large docking port Payload specs: Total mass: 533.3t Available fuel on orbit: 448t (= 14 jumbo-64 tanks) Monopropellant: 2250L (about 1/3 spent during the ascent) Orbital maneuvering configuration (discarding the last launcher stage fuel reserve): Payload + 1 jumbo-64 tank + 1 Mainsail engine => available DeltaV 185 m/s Launcher specs A. Structure 974 parts 3870t takeoff mass (dry mass = 1150t) Asparagus layout, in jettisoning order: - 4 stages of 6 lateral boosters each (4 x 6 x [2 x jumbos-64 + 1 x Mainsail]), - 2 stages of 6 main lift elements each (2 x 6 x [2 x jumbos-64 + 1 x Mainsail]), - 1 central stage of 6 main lift elements (1 x 6 x [2 x jumbos-64 + 1 x Mainsail]) B.Performance (Ascent Komputron design and analysis) TWR: average 1.75, min 1.4 Fuel reserve at 100 km circular LKO: 60t (among which 32t from the orbit maneuvering stage) for a total of about 335m/s of DeltaV (with no loss of payload) C.Test Flight Flight Plan (Ascent Komputron's optimizer result) Boosters jettisoning sequence End of injection phase Final orbital data: 508.8t of fuel = payload fuel + 60.8t reserve Thank you for reading David Ascent Komputron topic: http://forum.kerbalspaceprogram.com/threads/59899-NET-AscentKomputron-rocket-design-%28reads-craft%29-ascent-optimization-aerobraking

Yes you can! => http://forum.kerbalspaceprogram.com/threads/59899-NET-AscentKomputron-rocket-design-%28reads-craft%29-ascent-optimization-aerobraking And of course I do agree with you, also because IMHO trying to fly a complex mission "first time right" is the most rewarding gameplay by far... Cheers, David

Well for real-life IC design (microelectronics chips) you need a System simulator, a Schematic-level simulator, and a "back-annotated schematic" i.e. Layout-level simulator, all simulating the same electronic circuit at different levels of abstraction... so don't you dare complain at level 2! Edit: working on the Ascent Komputron, I do support the idea of course, but I understand some players don't want this

Hi DJRWolf, I don't want to interfere and IMHO all playing styles are good provided they give fun to the player! However I'm jumping in because your concern is exactly what drove me to work on this: http://ascentkomputron.blogspot.fr/ Forum: NET-App-Ascent-Komputron-rocket-design-tool-and-ascent-trajectory-optimization I can't say it will solve all the test cases you mentioned but at least it got me to Eve's surface and back right on the first design trial. I'm currently working on a .craft import feature to make the design description much easier (should be ready within a week). Please don't hesitate if you have any feedback and suggestions, Happy flying, David
