F-14 Development Update - Power!

[hannibal]

for the fact that heatblur was able to simulate the viggin with reverse thrusters... gawd knows what heatblur has lined up for the tomcat bombcat...

[Lt.Seahawk]

How are you going to Simulate FOD Damage? Are we required to walk the deck every morning prior to take off? ;)

[Nosferatuwhisky 1-1]

But can you tell why kids love Cinnamon Toast Crunch?

 

What percentage would you say you have left to go before we get the bird? I’m asking for a friend :)

[Shimonu]

I don't think Cobra's "mistake" of saying the LANTIRN was announced on Feb 19th was a mistake...

[westr]

I love reading these HB updates when they arrive

[RaceFuel85]

I believe the F-16 used a F100 engine as well IIRC?

 

The F-16 used the P&W F100-P200 engine where the F-111 used the P&W TF30..

 

after Block 30 the majority of F-16's used the GE F110 engine.

[Vitormouraa]

Very well done. Gas turbine engine is my area of 'expertise', and I have to say that this text is very well written, with many details showing how things work, but yet, it's simple enough for the general public to understand. :) By the way, the TF30 doesn't have a hyphen between TF and 30 :D (little detail LOL).

 

Here's a bit more information about the F110-GE-400 engines:

 

Length − Overall: 232 inches

Nominal Diameter: 45.5 inches

Max Radial Projection: 52 inches

Weight, Dry: 4494 lbs

Weight, Wet: 4592 lbs

 

MAX THRUST: 26,950 RPM: 14,666 (HPC) 8,257 (LPC) SFC: 2,104 AIRFLOW: 261 lbs/s

MAX CONTINUOU THRUST: 14,696 RPM: 14,459 (HPC) 8,038 (LPC) SFC: 0,576 AIRFLOW: 245 lbs/s

 

So a quick math shows that the engine at sea level, standard day conditions has a fuel flow of 56,702 pounds in an hour in AB. MAX CONTINUOUS having a Fuel flow (FF) of 8,622.

 

At an altitude of 35,000 at Mach 1.6 the -400 engine produces around 20,966 lbf and has an S.F.C of 2.261, airflow is 268 lbs/s.

 

Thanks for the update!

... and swing wings! (I was an avionics tech on these things!)

 

I was sheet metal on them back in the early 80s also the Fe-111

[Bloodhound57]

Great work HeatBlur!

Thanks - Heatblur has that PDF file as well. :)

 

Just for clarification, those conditions are a little different than those presented in the engine diagnostic panels.

F-14 Development Update - Power!

 

Yes. I noticed that. OAT is higher, around 5°C above ICAO standards/standard day. It's a great PDF though, showing the differences between TF30 and F110. One thing I would like to know about the second graph/middle panel is, why did HB not apply ram drag? Not sure if I am blind or what lol, but I don't think ram drag was applied in that situation? Net and gross thrust are basically the same?

Brilliant update, the amount of detail put into this is baffling. Thanks, Heatblur!

No air data computer though, so no auto sweep?

[Overvolt]

big news, interesting level of simulation q will be delivered in this module.

but with every news it seems more and more distant from the launch or is it just my impression?

 

Thanks Corbra for the update

[Dino Might]

I suspect (and could very well be wrong), that there's some discussion with ED and some strategizing on the part of HB to tailor an appropriate release date as they near completion. If they decide to wait until after Hornet sales die down, and that actually causes some delay of the Tomcat relative to when it could be earliest delivered, then it just means that the one delivered will be more feature-complete. We're losing a bit of early access time in that case, but not losing any playtime on the release version that is to come.

 

I'm with ya in wanting that bird now. I'd take whatever current iteration of chromecat that exists in a heartbeat at full price plus tip. But I satisfy myself with the understanding that later delivery means more complete module. We're going to be getting a gem.

Do the F-14's wings auto sweep? I think the computer in the FB-111A had magnetic core memory, that's about all I know about it. There was a wing sweep handle on the pilot''s side, along the canopy. I worked on comm/nav/ecm systems.

yes, the wing sweep programmer, when left in auto, will automatically select the optimum wing sweep for the mach in question.

Cue Frothing at the mouth

Great job Cobra!

[Wxtracker]

Is it just me or does that data photo, particularly the ground one show a semi textured cockpit! Puts on Tin Foil hat

[Sierra99]

Seriously? You're modeling each stage of the engine separately?

 

Unbelievable! I can not wait for this airplane!

I hope ED hasn't been screwing them around on release because of the barely A2A functioning F-18. Considering the F-14 was going to release to us before the end of the year unless something catastrophic happens :) And nothing catastrophic happened i am assuming that is the case although Heatblur will never admit that.

[IceFire]

Gonna be amazing,

 

We absolutely cannot wait for this !

[QuiGon]

I'm not an engine guy, but this sounds great!

I'm not sure about the FB but the F-111 does not have auto wing sweep.

[TomCatMucDe]

The work that is being done by Heatblur is tremendous. But I hope that this pursue of the finest details and the reworks of things won't delay the module for another year.
