Sabre Engines for SSTO

[Waster]

Now that development has reached a project milestone it may be time to consider adding SABRE engines (including design) into Kerbal. Almost like a real life Rapier.

The Rapier Engine is the Sabre engine, if you still don't believe me, notice how both engine names are also sword names. Man have some coffee before posting!

1, I don't drink coffee. 2, if you read the post I said (INCLUDING DESIGN). The Rapier looks nothing like the Sabre.

Don't be a troll.

Here's what a SABRE looks like:

Here's what the RAPIER looks like:

KSP doesn't model turbines in jet engines. All you can have of the SABRE is there already. Do your research.

The vast majority of KSP stock parts are not indentical to actual real life parts.

Rapier is definitely the KSP analog to the Sabre, the quad nozzles and mixed mode capabilities are a dead giveaway.

Only thing that we realy need is intercoolers and proper intakes for them. ATM any jet engine can go at any speed pretty much with out overheating. Real world jet engines will overheat due to friction at high speeds causing the intake air to overheat the engine. After all even a jet engine can only run so hot and needs relatively cool intake air to cool some of its sensitive working parts like bearings, turbine blades etc. Plus the hotter the intake air the less fuel can be burned to produce trust since the amount of fuel dictates turbine temperature. Jet engines are primarily temperature limited.

So any way an intercooler is needed and a proper intake for the rapier engines.

Now I my self use jets extensively for SSTO's and they make it possible to go anywhere in an SSTO in the solar system and back with payload and no refueling BUT its a bit unrealistic for the final game to have jet engines going that fast relatively speaking. So for game balancing Intercoolers and special intakes would be nice.

Now intecoolers could be used with JET engines to. The SABER engine has been proposed as a aircraft engine mode only version that still could do Mach 5 but do not have the rocket mode.

So I think for best balancing we need intercoolers, they are the heaviest part so they should be heavier then the engine they also require a proper intake for most efficient use. Esthetics's and drag reduction.

They could still be used with both JETS and RAPIER but with out an intercooler per engine the max speed should be mach 3-4 before overheating at 100% throttle and with intercooler mach 5-6 should be doable before overheating.

SQUAD would need to add the intercooler part at a minimum and all jet engines an rapiers would need a max speed with and without intercooler that also factors in fuel use in to the equation to determent the engine temperature and thereby when the engine would fail and go in to a broken mode.
