I've seen also what is written in the game, but they are "fake" values - the thrust drops to 0 at that speed values in contradistinction with the given values... NWM (talk) 02:40, 28 May 2015 (UTC)

The thrust of jet engines is defined in a way that makes it difficult to display in the stats table. The thrust at a given velocity and altitude is derived from two pre-defined curves in the .cfg files (specific impulse is constant regardless of thrust, unlike rocket engines). The turbojet, for example, has a maximum thrust of 1044 kN, but that's only achieved when traveling at exactly Mach 3 and exactly at sea level, which is a rare scenario in practice. A more complete way to define the thrust than what I put in the table is to list the thrust while stationary at sea level, the optimal velocity, the thrust at that velocity, and the maximum velocity. I couldn't figure out a nice-looking way to display that in the table, but if someone else wants to try, here's the values:

Engine	ASL stationary thrust	optimal velocity	thrust at optimal velocity	maximum velocity
Basic jet engine	115	Mach 1.67	1.46x	Mach 2.5
Turbojet engine	180	Mach 3	4.9x	Mach 5.5
Rapier engine	140	Mach 3.7	8.5	Mach 6

The rapier engine will probably switch to rocket mode well before it hits Mach 6

I see you already incorporated the new data into the table. The only “missing” part is the maximum velocity. — xZise [talk] 14:28, 28 May 2015 (UTC)
