WIP: F-14 B/D

Catfeet…
4100 tris…here are the good news: The tyres make up 4000. I’m estimating another 4000 for ‘rough’ details. Then trim it down.
Note the incorrect position of the main landing gear doors they’re way forward. That being said the wheels are in the correct position based on blueprints/photos and if you know the cat’s stance you can already see the position is spot on. Lots of adaptation, modelling and optimization to come.

Will there be a way to make her kneel properly in BMS?

Will there be a way to make her kneel properly in BMS?
From my time working on the other model I remember something about tying certain functionalities (i.e. kneeling) to DOFs of other moving parts. For example you can have the wings go into oversweep when users open the canopy. Logic being canopy open > wings sweep. Following that logic kneeling could be tied to something like that.
It might be even simpler than I’m making it out to be. For instance the key command for being ready when on CAT (is it still Ctrl-k?!) which fires the carrier DOFs (smoke, blast shield, etc.) could also fire the CAT position of the F-14. That would be front gear compresses to full down position and the ‘calibrated connection quick release bar’ would lower. The holdback bar actually never really moves so that is more of a question of carrier catapult modelling and implementation.
Further input is as always welcome, Baby.

For oversweep try the Wing Fold.
Fake kneeling won’t be needed

Pleased to see that job is going on.

I disagree. The appearance of a kneeling F-14 is not unlike a large cat about to pounce on prey. It’s a unique trait and is a big part of Tomcat culture.

What he meant was kneeling can be implemented without faking it by tying it to some other functionality. At least how I read it…

@SEG:

Seen that video a hundred times. Nice animation and model even though it runs fast which I’m sure the author realizes. That level of model detail will be unattainable given the limitations, even the brakes and rims are modeled in detail. Assume 10-15k tris just for the wheels. That being said, the main wheel strut connection to the fuselage is missing there and will be implemented (if ever so simplistic) here

Aircraft Automatically kneel when aligned with the catapult now. Blast doors come up automatically too. Cntrl+K o believe is the arresting hook toggle command. You get launched after a few seconds of full throttle. Shift+K releases you from the catapult, allowing you to move about the deck again. Handy if you get stuck on Cat 3 or 4 after landing.

Oh right…that makes sense. That’s what I get for reading and replying while I’m still half asleep

As a Slight Follow-up to my last post. I decided to take the current F-14 for a test spin in a TE. I did a Carrier take-off and it seems the people at BMS put a little work into her. The F-14 Starts on the deck with Wings Swept back,though not in over sweep. When you hook-up to the catapult as mentioned before,not only do you kneel,but the wings automatically Sweep forward to take-off position, flaps come out as well. She goes off the deck just fine, but I notice an RDC SPEED warning on the HUD above 250ish knots. I believe it has something to do with the model and the handling of the Flaps, as after some looking around, Using the key command to fully retract flaps fixes the issue. Though again, it seems flap control is automatic with Speed? Maybe it has something to do with the game considering the wing sweep as Flaps? I just don’t know.
Overall, fun thing to mess around with, though that placeholder Cockpit is real prohibitive of doing anything meaningful without memorizing every single key command.

Hey,
Yes, a lot of coding has been done for Swing wing and wingfold. Not only on carriers but also on the ground.
For carrier ops, the whole cat shot including lowering the nose of the AC has been modeled. Who said BMS is a F-16 only sim???The RDC speed is a warning that your flaps are still not up. This because the wings can not sweep back with flaps down.
The flaps on the F-14 are manual, so the pilot need to select them to up.
You only get a warning in the hud as it is not modeled that the wings will not sweep if the flaps are down.
Flying faster and faster with the flaps down will sweep the wings back and will look funny.Gr Falcas

The Flaps and LEF indicators were both reading zero when the RDC speed warning came up. I knew the Tomcat had manual flap control, I just thought it wasn’t implemented, due to the Flap and LEF indicators in the top left reading zero.

That’s right. As a slight extension I might add that part of the issue is the lack of implementation in terms of the flaps. The flap is not one single part as can be seen here:
Quote from NASA:
“Leading-edge slats and trailing-edge flaps are used to improve maneuverability at high subsonic speeds as well as to increase wing maximum lift coefficient at low speeds. The auxiliary flap shown in figure 11.32 is used only at low speeds to increase maximum lift. In normal operation, the maneuvering flaps, wing-sweep angle, and vane position are automatically controlled by a computer in accordance with a stored program that utilizes inputs from several measured flight parameters such as angle of attack, static and total pressures, and temperature.”
Without going into too much detail the main points are there is an automatic flap and slat retraction from takeoff and landing positions for airspeed greater than 225kts.
That being said the auxiliary flap only works when the wing is fully extended but manouver flaps (the main flap on the outside of the wings) and slats are deployed automatically by CADC/DFCS as a function of Mach number and AOA up until around Mach .85. Meaning even when the wing is not fully extended these control surfaces work and are deployed automatically by the system.
Specifically, if wing is aft of 50deg sweep the slat and flap (main and aux) are locked and remain fully retracted. The aux flap is locked and fully retraced aft of 22deg sweep. Between 21deg and 50deg the slats and main flap are deployed by system. In this regime the slat deploys up to 7deg and the main flap up to 10deg.
On early F-14s the glove vane is incorporated into this logic but for the purpose of this discussion can be ignored as the vanes were dropped later on. Apparently the only people ever figuring out how to effectively use the glove vanes are the IRIAF pilots and tweakers.

MLG
Modeling the main landing gear for now, had to start somewheres. You’re seeing the folding main strut support assembly, the main fuselage strut support bar and the actuator link on top. Also the scissor connection that supports lower part of the shock absorber where the wheel is attached. Basically the shock absorber fully decompresses, the upper link lifts the entire MLG up and forward, the strut support structure folds in half, the fuselage strut support bar retracts to the main strut and the lower MLG rotates inward.

Very nice work, can’t wait!!

and only 14k triangles? wow you drawn every line and vertex manually?
