Description

A Juggernoob-inspired marvel named Egg Zephyr. Built in the KSP 1.7.3 VAB with 99 stock parts.

Full credit to Juggernoob for the idea behind this one. (If he makes one with similar capacity, I will take this one down.)

The volume and fuel capacity of the inner Jumbo fuel tank has been scaled up to the full spherical volume: a total of 165,953 kallons LF and 202,832 OX. (You can camera zoom into the interior to pin open the tank for fuel transfer; else check the Resources LF/OX boxes; else use ShipManifest.)

Comes mounted atop a Zephyr lifter. Launch straight up; pitch over reaching 150 m/s; limit speed to 280 m/s until reaching 20km; then full throttle until AP is raised to 50km; only then jettison S1. Raise Ap to 70 km. Coast to orbit and circularize.

Fully-loaded with LF, dV is 19+ km/s.

Here are the calculations. A Jumbo tank has diameter 2.5m and length 7.5m, giving a volume of 53 cubic meters.
A 9m radius sphere has a volume of 3,053 cubic meters. Scaling the Jumbo’s fuel capacity of 2880 LF / 3520 OX by 53 : 3053 gives 165,953 LF / 202,832 OX, a total of 368,785 kallons.
