#BecauseThrustMatters: engine comparison of the different models on the KC-137Rs (including former ones):

Image

From left to right: Pratt & Whitney JT4, IAE V2500, CFM 56 and CFM LEAP.


One thing I cannot understand is why the engines FDM of the 707 are Rolls Royce Conways and the 3D is PW JT4...

There's 1 FDM, but 2 engine files.

Oh alright so they share the same FDm, only the thrust changes according to engine model.
This clarifies all. ;)

All variants will soon feature latest IT-AUTOFLIGHT build and new engine sounds for both CFM and IAE.

New commit now fixes the HUD to all variants, implements the radar view to the E-8R and adds an additional antenna to the RT.

Mmmm wing flex implementation is not as easy as it seems... especially if the 707 model uses one single file for wings:

Anyone who has some kind of knowledge in this?

ahahahaha

@jmaverick16 the 707 wing is stiff, and does not flex alot. Don't bother with it, it will only hog frames.

IT MUST be seperated parts of wing (see the MD-11)

KC-137R family is getting more digital!

In the past few days many improvements have been made to all the 6 variants of the pack, making the current planes versions the most advanced ever seen. Thanks to all the people involved in helping in the project now we have:

- custom EFB fully working in the overhead.
- digital numbers added to the engineer fuel instruments, like the latest RL planes have.
- general sound improvements including an altitude alert system, improved GPWS and more.
- fully working ITAF autopilot in all versions.
- Full RC-137R Rivet Joint 3D model, matching the real life RC-135V/W.
- large livery pack for the E-8R JSTARS including most of the current RL planes in service.

And a lot more!

And keep in mind it's still not finished and in active development!

Newest AWACS version, forget the old one.

Thanks to Martien VDP for the upgrade.

All aircrafts are now getting an upgrade, which is coming from the real aircrafts!

--//--BLOCK 45 --//--

Image
XX=Engine not running

NOTE: In CFM versions, the EPR stays XX'ed out. This is normal behavior, as CFM/GE engines do not have an EPR parameter. When the Block 45 is complete, I will make a CFM versions with N1 as the primary.

So far working: ENGINE: EPR, N1, EGT, N2, FLAPS: Green bars and labels

Next to come, nav display, FF numbers, Oil Pressure, EPR limits (N1 limit will come with CFM versions)

Note: Missing from the screenshot: EPR, N1, EGT, N2 labels, will add via OSGtext in a moment. I removed them from the texture, as they were causing some issues.

I have also installed a new autothrottle system, which uses engine EPR (IAE) or N1 (CFM) to set thrust. The Speed-by-throttle needs a little more work, it works, but it needs a little more precision.

In addition!
I have added a system I call Wing Leveller and Pitch Stabilization Augmentation System (WL/PSAS) This system was designed to make the tanker more stable in flight for refueling, as the heading drifts/pressure changes can cause the AP to move the plane around, which is not optimal for refueling. There are two parts, the Wing Leveller is self-explanatory, but PSAS is similar to a CWS system. The elevator input (controls/flight/elevator) will now adjust target pitch, instead of the elevator. The elevators are adjusted by PI-Simple controller for elevator, and also autotrim. This way, setting a pitch of 4deg UP, will be kept, even if thrust changes, or the aircraft banks. I am also adding a VS=0 option to it, but that is not ready yet. This can be controlled by the WL/PSAS menu inthe aircraft menu, cockpit switches, and and a key to open dialog will be added.

Cheers
Josh

Would you be able to help us find with the models cause crashes when spawning over multiplayer in a particularly crowded area?
It's really important to solve that issue and since the devel team can't stop updates to search for possible unknown issues it'd be nice that more people can contribute to improve this aspect.

I've pushed a few commits removing unnecessary MP tranmissions. This might fix a bit. I'll keep looking into it.
