The Mk1 Fuselage - Jet Fuel is a 1.25 meter “Size 1” fuselage containing only liquid fuel (a.k.a. jet fuel, or kerosene). Like all fuselages, it cannot carry oxidizer. It is not to be confused with the Structural Fuselage which cannot hold fuel or oxidizer.

It and the Structural Fuselage are the only fuselage parts with circular cross-sections. As such, they mate cleanly with Size 1 parts like the FL-T series rocket fuel tanks.

Description

A standard fuselage that carries fuel for spaceplanes. This one is chock-full of jet fuel. Not as resistant as it's counterparts, but jet fuel is more efficient than the other fuels, without mentioning lighter.

Comparisons

This is the least-efficient by mass of all the fuselages. The mass is 3.14 times the dry mass, with all the other fuselages[outdated] having a mass five times the dry mass when fully fuelled. However, its impact tolerance of 20m/s is 3⅓ times greater than the 6m/s typical of rocket and RCS fuel tanks.

With the introduction of tweakables in version 0.23, the oxidizer can be removed from rocket fuel tanks giving an even better fuel-to-weight ratio, but landings could subject craft to impact sufficient to break them which the Mk1 fuselage would survive. Liquid fuel tanks have then mass between 2.9 and 4.6 times higher as their dry mass.
