The Triangle

[Eat Uranium]

The Triangle series of heavy lifter rockets stem from the first rocket I made in 0.12x1 (with the intention of getting as close to the sun as possible). They have since been my only rockets flown in the x1 experimental.

The Triangle series is centred around a common lower stage. The 6 LFEs and 3 LFE-Gs will burn for the first 3 and a half minutes (the larger LFEs extinguish about 20 seconds beforehand). Following that, the SRBs will inject the payload into a holding orbit (some designs require a small auxiliary burn for this). After that, the payload is free to go pretty much anywhere.

The Triangle I is the simplest of the bunch and was my first model. It was flown within 2 Gm of the sun but was not capable of return to Kerbin.

The Triangle II-ix is tailored towards Mun landing missions, with a small upper stage (awaiting stock landing legs - please add your legs of choice in the meantime).

The Triangle III-ix was tailored towards the mission of escaping the Sun\'s gravity, a task it excelled at.
