KR-1 and KS-25 on a 1.25m base, High-Gimbal Engines

[Whirligig Girl]

I'd like to see a standalone KR-1 and KS-25 engine on a 1.25m base, so that 3.75 meter parts aren't op, because there'd also be equally scaled parts for 1.25 meter parts. These standalone parts would come after the clustered parts in the tech tree. The KS-25 would have an extreme gimbal range, but changing gimbal range past 1.5° would require holding down a key (Perhaps F, no one uses the SAS Toggle anymore) while using QWASDE, and holding alt+F would reset it. Gimbal change would be relatively slow. I remember proposing this idea (well, similar to this) to C7 on a livestream, and he thought this would be a good idea.

Kerbodyne KS-25 Liquid Fueled Engine

This super-high-power rocket engine is designed to be used on asymmetric rockets, as it can be highly gimbaled to compensate for a change in the Center of Mass. Due to this, it can not have anything mounted beneath it. However, this mechanic combined with super-high thrust causes the engine to be extremely expensive. Don't break it.

Thrust: 530 kN

Isp(atm): 320 s

Isp(vac): 355 s

Weight: 1.625 t

Gimbal Range: 1.5°

Gimbal Change Range: 10°

Gimbal Change Rate: 6°/s

Cost: √5400

Kerbodyne KR-1 Liquid Fueled Engine

The original KR-1 Liquid Fueled Engine has just been released by Kerbodyne, and is a small, very high power rocket for small-sized heavy-lift rockets. It's advanced technology is very valuable. Don't waste this engine on small launches!

Thrust: 335 kN

Isp(atm): 290 s

Isp(vac): 345 s

Weight: 1.2 t

Gimbal Range: 0.5°

Cost: √2800

What would the fuel consumption rates be?

[Whirligig Girl]

I gave the Isp and Thrust, do the math.

Solve for

is the thrust in newtons

is the specific Impulse

is the mass flow rate in kg/s (lb/s), which is negative the time-rate of change of the vehicle's mass (since propellant is being expelled).

is a constant equal to 9.81 (Acceleration in m/s^2 due to gravity at Earth's Surface)

Seriously, the mass flow rates are calculated in game, not defined in the cfg. You define Specific Impulse in the Atmosphere Curve and the Thrust, and the game calculates the fuel rate using that.

how about this?

[Roastduck]

Hmmm. I might get creative with some parts files and make a prototype of this

edit: creative relative to myself, since i'm not a programmer

[Whirligig Girl]

Looking forward to that.
