engine efficiency charts

[fommil]

It would be really amazing if engines came with two efficiency charts:

* thrust vs generated force

* thrust vs fuel consumption

This would really help fine-tune use of the throttle, and perhaps engine choice.

[Kasuha]

Each engine comes with minimum thrust (usually zero) at 0 throttle, and maximum thrust at 100% throttle. The relation between them is linear.

At given atmospheric pressure, throttle is also linearly proportional to fuel consumption.

Atmospheric pressure affects engine Isp and that in turn affects engine fuel consumption.

Special case are Jet engines but for these graphs should be available somewhere around these forums.
