WIP: F-14 B/D
-
You posting again…
Can’t argue with that. Had a run in a corporate environment that left me close to absolutely f*** all free time :).
Good to see you’re still lurkin‘ around…pun intended.
-
Awesome to see this project coming to life! I think BMS would be a great enviornment for the F-14D! Cannot wait to see this model finished! Most importantly I can’t wait to see a somewhat decent cockpit incorporated so we can fly this bird!

it rotates up as one part even if only the main flap is deployed, will have to check if in RL it is a two piece componenthttps://i.imgur.com/gaI9HTr.png
Hi Stingray 62,
Congratulations for the work you are still doing on this bird.About Tomcat’s flaps law :
- Auxiliary flaps have only two positions > UP or DOWN (35°)
- In addition to some speed’s limits, flaps positions limit the wing-sweep position :
- Less than 21° sweep if the auxiliary flaps are down.
- Less than 50° if the main flaps are extended.
- Between 21° and 50° sweep > main flaps will extend but auxiliary will remain retracted.
For info, slats don’t affect the wing sweep posit
NATOPS procedures say :
- Landing > Wing sweep = 20° + all flaps full down as one piece (35°)
- Take off > Wing sweep = 20° + flaps as required (Flaps up take off are available according to gross weight and thrust conditions !)
-
Thanks for the details but the flap is clear in terms of actuation. If you check the pic again or google F-14 cove doors you will see what I mean: when the flaps are deployed the spoilers and helper plates rotate down 2 degrees to meet the ‚cove door‘ this seals up the wing area along the flap. The question was if the cove door and spoilers seal up the entire area along the wing regardless of the main/aux flap deployment.
I’ll consult my photo bible tonight but suspect this is actually individual actuation.
-
OK sorry for my bad understanding
Not to be annoying: If i’m not mistaking in picture 2 and 3 of your april 22 's post, wing sweep looks at is minimum (around 20°) so in that case, auxiliary flap should be extended (because this action is linked with “main flap down more than 5°”).
I 'll look at the cove door. -
WHAT A BEAUTY! well done! Can wait to see it in BMS! Time to refresh a bit my dusted F-5a i think (lol) and also keep on thinking for an -F as well… gotta see how will go i have a lot to finish

I 'll look at the cove door.If you do find sth please also be on the lookout for the actuation of the ‚eyelid door. These are aero elements on the top front of the flap that rotate up at flap 0 to seal the gap between it and the spoilers and close down once flap is deployed to create the round shape of the flap. I’ve modeled these parts but here also am unsure how they are actuated in regards to main/aux and if it’s a simple up/down or scheduled motion.
This is cove door up and eyelid doors down:
flap down full eyebrow closed cove raised
Eyelid doors up (w/o flaps), spoiler assembly and cove doors:
All elements are actually separate meshes that are joined together. Hope it helps in understanding.

Hooking…

Here’s what I’ve found :
Looks like :- cove doors move as one piece ;
- cove doors share the same hinges than flaps ;
- cove doors have two positions : DOWN and UP ;
- same cove doors process for the auxiliary flap.
Flaps UP (0°) = Cover door > down (Clean profile)
Flaps MANEUVER (0° > 10°) = Cover door > down (not enought separated from flap to move up)
Flaps DOWN (at 25°) = Spoilers at -4.5° to meet cover door ;
Flaps DOWN (10° > 35°) = Cover door > up (My guess is that door going directly to UP… but I’m not sure) -
Got new (old) workstation set up and it blasted through this render in under 3 1/2 minutes…me like.
In other news that cove door creates more issues:
Protruding through the wing topside. Since I measured the cove door pretty exactly and also set its rotation limit me thinks that either the wing itself is too narrow in that region or the modeling of the spoiler ‘trays’ is inaccurate maybe due to spoilers that are a bit too thick. Thing is I have measurements for the cove door and no measurements for anything else :).

Stingray i’m very happy that we have you back on full force
Another “free” modeller around is always good.
Out of morbid curiosity how many polys so far?
Amazing work very very professional. -
Glad to be here. Geometry is still unchanged, including drop tanks and excluding ordnance ~ 71K tris, without landing gear ~ 55K tris - there’s minimal room for optimization with the gear.
Again, I did not model this using subdivsion modeling so there’s no easy scaling it up or down as it is modeled as is. Good news is the 55K include details like the variable exhaust nozzles, GE turbofan, detailed cockpit, antennas and lights as well as the wings which make up almost half the geometry so not too shabby.
Refueling probe, pilots and some actuators for moving surfaces still need to be modeled.

Are those 55k all traingles or are there multi vertext poly’s as well? An exported LOD is all triangles. Just posting in case you didn’t know this…
Great model! -

Great model!It’s all tris. Thanks for clarifying!

Mind if I perturb you Stingray - anything new you can tease us with?

Ara’ & Cloud… I had to guess what you had in your mind :lol:
With best laughing regards.

I’m as always almost speechless about how you can find all that good stuff, Toro… well done once again, dear mate.
With thankful regards.
