Exhaust may need to be tweaked

Hello,

I tried to sling loading a 680kg crate with the huey empty (no troop, not armed, 50% fuel)

I was flying low, slowly around 20 knots, but i needed to clim a hill for building a radar.

I was looking carefully the exhaust gauge which was getting high very very easily.

I tried to climb that hill very smoothly and tried to put the exhaust gauge in the green as much as possible but for climbing that hill i was forced to push the collective smoothly.

On the top of the hill I stabilized successfully for beginning my descent and I've lost my turbine due to exhaust too high.

I really don't understand what i did wrong.

My location was not in high mountain it was at coordinates 43°56'56" N 41°35'56" E

Hi,

Here's a thread on the subject...

I really don't understand what i did wrong.

Probably nothing, it's a known issue and being worked on by BST.

As the EGT thread is quite long I'll summarise it here :

• The current EGT's at 0 ft are similar to the RL 6000 ft Max Torque available curve.

Once BST correct EGT and Torque, you should be flying to max torque 50 psi (gearbox limitation) upto approx 4000 ft and to 615°C EGT (625°C 30 min max) above that (engine limitation).

For now - EGT is king at all altitudes.

• BST feedback:

Thank you guys for being involved! Our helicopter department specialists have an idea about what needs to be done for EGT tuning.

We would need to adjust changes after new DCS version will release, and so you would be able to try it as well. We will make announcement when changes will hit openbeta, and we think we will do same format and listen what you will say, like we did here in this thread.

Team developed solution which will include tune regarding torque and temperature. As soon as programmers will implement it it will go for patch.

 

Also task was created for fixing gauge green zone.

The fix implementation taking more time that we would want, but Huey engine needs some considerable changes for this new solution to be in place. We jumped on our engine programmers with this while they were in the middle of F/A-18C project, so now they are split between two tasks and not going really fast. We hope, that when F-18C will go early access, patch for Huey engine will also be close to completion.

... slowly around 20 knots, but i needed to clim a hill for building a radar.

I would say try to fly a little bit faster, you are hardly in ETL at 20kt. I don't know at what speed you have the most surplus power avaliable for the DCS Huey, especially with a sling load, but it's often at around 60kt, and that's the speed it's easiest to maintain the temperature. You need more power at 20kt than 60kt (disclaimer due to sling load). Try and see.
