Physics [RELEASED] Silantro Flight Simulator

Hi, is it possible to edit/change airfoil type/shape at runtime for aircraft?

 

Yes you will .
//


1. Creating new Airfoil


//
2. Editing existing Airfoil

 

#UPDATE

New control setup with different controllers (still in development)


//
//
Osprey Update
//
1. Vertical Takeoff

//
2. Short Takeoff Configuration

 

This is the best flight simulator asset I've ever seen!

 

I don't understand how to take off in demo version? Plane reaches 55 knots and then stops reaching speed to take off.

 

Thank you very much . Please don't forget to rate on the asset store.

 

Wow.. I'm sorry that's happening.

1. Which of the aircraft demo!?
2. Was(were) the engine(s) at full power!?
3. Was the parking brake disengaged!?

 

The preflight check list is pretty simple

1. F1 to start up the engine(s)
2. Press down Alpha 1 to accelerate the engine(s) to full power
3. Tap X to release or disengage the brakes (might require multiple clicks due to a bug in the initial release)
4. Once the aircraft reaches takeoff speed, rotate by pressing down the (down or S) button.

 

There is only one aircraft(A29 SuperTuncano). Maybe you forgot to reload demo because I saw on the screenshot of demo that there are 3 aircrafts.

 

Yeah, I had to pull the Spitfire due to problems with the aircraft setup and I want to replace the Phenom 100 with the F-35 as the official jet aircraft.

Can you takeoff properly from the tucano now!?

 

I tried to test it in my notebook and it works now but in my another computer it still reaches 55 knots of speed and doesn't speed up further to take off.

 

Woa... So the problem only happens on your other computer!?

 

Yes. On the screen is the maximal speed that the aircraft reaches.

 

Maybe it's an issue with your other computer. What are the specs and can you send the "output_log.txt" file in the demo data folder.

 

From the log file it seems the Black box component (SilantroDataLogger) couldn't get permission to write data on the computer, and somehow interfering with the normal operation of the scripts.

 

Any chance for a Web demo? Some of us don't do Windows.

 

OK, I've just purchased the asset and I'm having fun exploring it. But there are a number of issues out of the box:

• Missing scripts in various places, for example, on the Explosion Effect and on the GUI System (in the JetAircraft sample scene).
• Also in the JetAircraft sample scene, the camera is in front of the plane, facing backwards, instead of behind it. How do I fix that? (And how in the world did you fly it that way?)
  
• Possibly related, the whole jet aircraft seems to be backwards — the local +Z is pointing towards the tail, instead of the nose.
  
• Both samples have the data logger set to save to C:/Users/ACER USER/Desktop/, which obviously doesn't exist on my Mac, and wouldn't even exist on most Windows machines (since most users are not named ACER USER). This causes an exception that prevents running until you disable the logger or change the path.

These look to be mostly errors in packaging up the asset or preparing examples, so I'm by no means giving up on the asset. I hope this feedback will help you make a more polished release.

 

More troubles (trying to set up my own plane)...

It seems that many scripts are trying to find the instrumentation via tags, with code like this:

Code (CSharp):

1.         GameObject brain = GameObject.FindGameObjectWithTag ("Brain");
2.         if (brain.transform.root == gameObject.transform.root) {
3.             instrumentation = brain.GetComponent<SilantroInstrumentation> ();
4.         }
5.         if (instrumentation == null) {
6.             Debug.LogError ("Instrumentation System is Missing!! Add COG to aircraft");
7.         } else {
8.             instrumentation.boom = EngineRun;
9.         }

This is a horrible way to do it, because it fails if there is more than one Silantro plane in the scene! (The second one will pick up the brain of the first.) It's also fragile and unnecessary. Please use something like transform.root.GetComponentInChildren<SilantroInstrumentation>() instead.

(And note: there is never any reason to write gameObject.transform... just transform is the same thing but shorter and faster.)

 

Thanks Joe, I've fixed the missing scripts issues in the update I'm working on (it's the destroy after time script that is missing) .

The only aircraft with the Z axis pointing backwards is the Phenom 100 and this is a problem with the modeling of the aircraft, I've however replaced it with the F-35 as the sample Jet aircraft.

The samples were made on my system, that's why I had to make the save path specific. Anyone using the Package just has to set that path to his/her system path (its not hard coded into the system).

 

I designed the Simulator in such a way that each component can work independently but would still require a central controller to bring things together, but the fact that I created the engines and some other systems that require this instrumentation component before the VMC /Controller created a big issue.

The engine is a child of the aircraft, the instrumentation gameobject is also a child of the aircraft so using transform.GetComponentInChildelren was not an option, transform.root.GetComponentInChildren works but fails when the aircraft is not the root gameobject (especially if there are other aircrafts within the root object). Out of frustration, I opted for this quick and inefficient fix to buy some time

The issue has been solved in the update however, what I've done now is to have the developer manually assign the aircraft instrumentation in the VMC/Controller system (it will then assign it to all its child components).

 

##UPDATE

STOVL system Update 100% complete!!!!
Demo will be available soon

F-35 Complete VTOL Test
1. Vertical Takeoff (0:0-0:50 mins)
2. Transition to supersonic flight (0:49-2:38 mins)
3. Return to Hover (2:40-3:30 mins)
4. Vertical landing (3:35-4:25 mins)

 

Just leave the path blank (before creating your Asset Store package). The code should then write to the default directory, which will be the directory containing the project. Users can still change it if they want, but at least they don't get an error right out of the box.

In addition, you should catch the exception that happens when the path is invalid, log a warning to the console (just once), and then continue without the data logging. That too would be better than preventing the demo from running.

 

That sounds like a decent solution. I would also be fine with some component that represents the aircraft itself, and has to be at the top level. Then child systems (which might be located anywhere) could do GetComponentInParent<SilantroAircraft>() to get that top-level component, and then call GetComponentInChildren or GetComponentsInChildren on that to find any other references they need.

 

F-22 Raptor Teaser

 

Wow, that’s what I wanted!

 

@Oyedoyin1 we discussed real-time computational fluids solutions (for objects obstructing flow among many other things). @Keijiro-UTJ just published a compute shader based solution. ("A straightforward GPU implementation of Jos Stam's "Stable Fluids" on Unity").

 

Thank you very much ... That's part of what i've been looking for.
I'm also thinking of using CFD (Computational fluid dynamics) to improve the aircraft drag properties, know any good free or "not too" expensive software!? The one from Hanley is about $895-$6000.

 

#UPDATE

A-10 Thunderbolt with the updated GAU-8 Avenger (fixed the barrel rotation).

 

Could you also add a wingtrails?

 

I will. I just delayed adding any major effect so I can effectively monitor the "script performance" without interference

 

#UPDATE

New KC-10 Extender Aircraft setup, heaviest setup I've had so far (Total weight almost 250,000kg!!!!).

It's going to be used for aerial refueling missions purposes in the future

 

Very nice! Wait for the demo update with new aircrafts!

 

#UPDATE

New additions
1: Reverse Thrust for Turbofan Engines

2: Incremental Braking system (to brake gradually)

 

W

here do you get the 3D models ?

 

Mostly from "Sketchfab".

 

Me-262 Sturmvogel setup with weapons test.

"Aircraft per System" mission.

Available aircrafts in each category ;

1. Low Bypass Turbofan : F-35 Lightning
2. High Bypass Turbofan : KC-10 Extender
3. Turbojet Engine: Me-262 Sturmvogel
4. STOVL System : F-35 Lightning
5. Piston Engine: P2006T Tecnam (In development).
6. Turboprop Engine : A29 Tucano
7. Main Fighter Aircraft : A-10 Thunderbolt
8. Turboshaft Engine : V-22 Osprey (Still unstable during sharp rolls)


Would have added more aircraft examples but I'm trying to keep the Package size under 150MB.

 

I am having various errors and warnings reported in Unity console. One set of issues is reported when I load the package. Second set of issues is reported when I play test the scene. And yet another set of issues is reported when I stop play testing. See attached.

 

Yeah I'm sorry that's happening. I forgot to reset the data save path to default before uploading the Package, that's why you're getting the errors.

FIX: Find the black box gameobject in the aircraft hierarchy (should have the script "SilantroDataLogger" attached to it). Change the file save path to a valid path on your PC e.g C:/Users/......

Remove the missing script attached to the "GUISystem" game object under scene objects.
That should do it

About the warnings, they're just values I've created for future use, that have not been assigned a function yet... It's nothing to worry about.

 

Oyedoyin1,

I purchased Silantro for a project my students are working on, and it works great, but we're having difficulty creating a heavy aircraft. Would be able to send theKC-10 for us to see how to setup a big and heavy aircraft?

Thank you for all your hard work,
~Pat

 

I'm glad you're enjoying the Package, please don't forget to rate it on the asset store

Send me an email, lemme try and solve the problems/ Guide you through the setup.
Most of the components on the KC-10 are updated versions of the current release and combining them with the one you have might be problematic.

Hey @Oyedoyin1 - Got a question about this asset.

Does this support Helicopters?

 

Actually No.
Its just for fixed wing aircraft (including the V-22 Osprey).

A separate Simulator for Rotary Wing/Helicopters is currently in development.

 

Hi, just to ask if that is ok, when you say fixed wing, would that include drones, gliders , possibly paraglider/flexifoil ? I imagine Paraglider type might not work as the wing is not exactly fixed.. can aircraft without engines be modified to fly with thermals somehow?

 

You should with just minor adjustments and modifications. Straight wing drones and gliders can fly with the system as it is as long as they are given a starting velocity or "push" e.g dropping from a powered aircraft.

//PARAGLIDERS//FLEXIFOIL
The aerofoil system can be modified to get a shape close to that of a para-glider or flexifoil by using multiple aerofoils and angling them. Check out this sample;


Note: You can use more aerofoils to get a smoother shape, but be conscious of its effect on performance.

//THERMALS INTEGRATION
Thermals generally affect wind speed (from my little knowledge of kite gliding )


//

//
So all you have to do to integrate it with my system is to find a way of modeling the "thermals variation" and how it affects or changes wind speed. This value(wind speed) can then be used to modify the "local wind" variable of the aerofoils.

 

#UPDATE

New PC finally arrived!!!, and ive already implemented some massive updates to the aerofoil system.
