when active does not touch the way the YASim jet calculates fuel flow, but separates out the afterburning component of thrust, calculates the TSFC of that component and uses the same method of fuel flow calculation for the afterburning component then adds it to the existing fuel flow
When inactive (atsfc doesn't exist or is zero) it just behaves exactly as before
I finally got around to testing this small patch thoroughly, and I'm satisfied that it doesn't affect anything else & works across many different versions (i've been testing it with current as it has changed over the last 7 months)
state. The only really obvious problem was a giant negative engine
RPM, which happened because of a lack of clamping in the engine code
combined with the YF-23's ability to actually reach speeds near the
engines _vMax value. It's not clear to me that this will fix the
superthrust issue at high AoA's, but it's an obvious bug nonetheless.
(and not the throttle setting), but the recalculation left in a degeneracy
when the target/throttle setting was exactly zero. Zero times a big number
is still zero. Fixed to use real math, not theoretical math.
Dynamics (Sim)ulator. Basically, this is a rough, first cut of a "different
take" on FDM design. It's intended to be very simple to use,
producing reasonable results for aircraft of all sorts and sizes,
while maintaining simulation plausibility even in odd flight
conditions like spins and aerobatics. It's at the point now where one
can actually fly the planes around.
