Maarten, I thought that might be a useful shortcut too. Did a bit of tinkering in Airwrench, and some wholesale cutting in pasting from the Bear to the Antei; the result didn't crash FS9, everything was spinning rather nicely ..... mind you, it wasn't going anywhere, it refused to pick up any throttle inputs at all.
So that one went in the bin, and I am (along with the rest of you) back to square one!
Andy,
It took a bit of trouble putting the cells of my Guinness and depression affected brain into action, but yesterday the penny dropped.
After renaming the existing air files in the Samdim Tu-114/Tu-126 folder "Tupolex Tu-114.orig" resp. "Tupolev Tu-126.orig", I copied from Samdim's Tu-95 & Tu-142 the airfile "Tu95MS" into the Samdim Tu-114/Tu-126 folder twice. Then I renamed these copies "Tupolev Tu-114" and "Tupolev Tu-126".
Then I replaced the engine section of the aircraft.cfg as follows:
[GeneralEngineData]
//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
engine_type = 5
fuel_flow_scalar = 0.38
min_throttle_limit = -0.22
engine.0 = 18, -40.8,0
engine.1 = 29, -21.2,-2
engine.2 = 29, 21.2,-2
engine.3 = 18, 40.8,0
[smokesystem]
smoke.0 = 38,-13.3,-40.8,Fx_95smok
smoke.1 = 38,-13.3,-21,Fx_95smok
smoke.2 = 38,-13.3,21,Fx_95smok
smoke.3 = 38,-13.3,40.8,Fx_95smok
[TurbineEngineData]
fuel_flow_gain=0.018
inlet_area=1.0
rated_N2_rpm=8450
static_thrust=156
afterburner_available=1
reverser_available=1
[turboprop_engine]
power_scalar=1.0
maximum_torque=72600 ;H:maximum_torque(72600)
[propeller]
thrust_scalar=1.0 //Propeller thrust scalar
propeller_type=0 //0=Constant Speed, 1=Fixed Pitch
propeller_diameter=18.368 //Propeller Diameter, (feet)
propeller_blades=8 //Number of propeller blades
propeller_moi=530 //Propeller moment of inertia
beta_max=21.4 //21.4 //Maximum blade pitch angle for constant speed prop, (degrees)
beta_min=6 //8 //Minimum blade pitch angle for constant speed prop, (degrees)
min_gov_rpm=8450 //25520 //Miminum governed RPM
prop_tc=0.008 //Prop time-constant
gear_reduction_ratio=11.3 //15.4 //Propeller gear reduction ratio
fixed_pitch_beta=0 //Fixed pitch angle of fixed pitch prop, (degrees)
low_speed_theory_limit=8 //Speed at which low speed theory becomes blended in (feet/second)
prop_sync_available=1 //Prop synchronization available? 0=FALSE, 1=TRUE
prop_deice_available=1 //Prop de-icing available? 0=FALSE, 1=TRUE
prop_feathering_available=1 //Prop feathering available? 0=FALSE, 1=TRUE
prop_auto_feathering_available=1 //Prop auto-feathering available? 0=FALSE, 1=TRUE
min_rpm_for_feather=700 //Minimum RPM for prop feathering
beta_feather=91 //Feathering pitch angle (degrees)
power_absorbed_cf=0.95 //Coefficient of friction for power absorbed by propeller
defeathering_accumulators_available=0 //Defeathering accumulators available? 0=FALSE, 1=TRUE
prop_reverse_available=1 //Prop reverse available? 0=FALSE, 1=TRUE
minimum_on_ground_beta=1.0 //Miminum pitch angle on ground, (degrees)
minimum_reverse_beta=-0.0001
//Minimum pitch angle in reverse, (degrees)
And, hurray, the Tu-114 started to behave. I haven't tested it very thoroughly (yet), but so far the old girl does what I expected her to do. Nice start-up of the engines, props counter-rotating at different speeds, plane taking off nicely, much better flight behaviour (trimming much finer than before). So that's a start.
Like I wrote before, I'm not very ambitious as far as tweaking flight dynamics concern, but maybe this is a nice starting point for people more accomplished than I am.
The Tu-126 should show the same kind of behaviour too now. I didn't check that yet, nor did I perform the same trick on the Antonov An-22 yet.
