General Question thrust rating in 2010p1

[gattispilot]

Ok how do determine thrust in 2010p1?

I have a vessel2 Eagle3 which I compiled in 2010p1
Same thrust setting,...

But the max thrust is
6.4M

but running the same vessel in 2060 max thrust is 30.6

const double MAX_FUEL = 36000.0;
const double MAX_MAIN_THRUST = 1600000.0
const double MAX_HOVER_THRUST = 410000.0;
const double MAXRCSTH = 12000.0;
// Impulso específico para los motores de fusión
const double ISP_FUS = 240000.0;
// Imuplso específico para los motores químicos
const double ISP_QUI = 105000.0;

th_main = CreateThruster (_V(0,0,0), _V(0,0,1), MAX_MAIN_THRUST, ph_main, ISP_FUS);

Orbiter 2010 displays thrust in terms of the force being applied to the vessel--6.4M newtons. Orbiter 2006 displayed thrust in therms of the acceleration being applied to the vessel, 30.6m/s^2.

I have no idea why it was changed--acceleration was a lot more useful than force.

Thought it was just me...

Ok I guess I need to reduce the thrust for 2010p1 because the Eagle is too fast

Um... :facepalm:

There's no difference in the thrust produced by your engine between Orbiter 2006 and 2010. The only difference is the value that's displayed on the HUD. In Orbiter 2006 that value is the acceleration produced by the engines. In Orbiter 2010 that value is the force produced by the engines.

There is a difference. As the eagle flies faster in 2010 than 2006. It also takes more rcs and hover to lift off

Hielor,
I'm with Gattispilot on this. The Eagle3 variant he's built for 100606 and 100830 is modeled on Jorge Iglesias' New Eagle. There is a significant difference in the perceived thrust between the two craft in the latest iteration of Orbiter and the New Eagle in 060929. In the former ships, I can achieve orbit at 1/2 throttle and can't exceed that setting without becomming a fireball on launch from KSC. That never happened even at full thrust with the later ship. I'm a not a Physicist and my physics is pretty rusty but I thought F = MA. If the force and acceleration are the same between the two ships has the mass changed?
