(Exhaust) Fire at Engine Start-Up...

[DSPALLASVI]

Have put some triggers in place that shuts the Huey's engine down when the throttle is in the wrong position during engine start-up.

This wrong throttle position results in an excess of fuel, causing flames to come out of the exhaust during start-up.*

 

After three starting attempts that caused the fire alarm to be triggered, the engine is shut-down for 1 (one) minute.

After that time, you can re-start the engine with (hopefully ;-) the throttle in the right position.

The throttle STILL in the wrong position will simply NOT allow you to get the engine started.

Note: with the throttle initially in the right position, the Fire alarm will NOT be triggered and you can have a nice practice flight:)....

 

Of course it would be rather unrealistic to use the RL reality of 3 (three) start attempts allowed in ANY ONE hour... sort of defeats the purpose of the sim... :music_whistling:

 

Though the RL manual is quite strict about that in the 'Power Limits'→ 'Engine Limitations' section:

b. Maximum starter energize time is 40 seconds

with a three-minute cooling time between start attempts

with three attempts in any one hour.

In this case, you can use the rotor coming to full-stop to "simulate" a three-minute cooling time.

 

Anyway, thought I put the Fire Alarm to a nice use, as I have not seen it ever being used anywhere, at any time in this Huey model.

And that while the exhaust flames AND the EGT shooting up into the RED have been modeled quite nicely... :doh:

 

That, plus it was a nice exercise to see if I could simulate an engine fire at start-up with the triggers available in the Mission Editor....

 

* = Of course, in this Sim there's no penalty to be paid when you cook the engine at start-up... but for those of us flying on the 'honour' system, it might set some restrictions that make it feel less a game and more a Sim... :)

So it doesn't cook the engine then in the sim when you do that? Because I usually see flames on my startup but everything works as normal, lol, thought it was just how it works, I will have to check out what you mean then.

That's seems a bit overdone, you might see a brief reddening of the exhaust but hot starts normally weren't accompanied by flames though they were destructive of the hot end. If the combustion chamber drain malfunctioned you might get some torching but you wouldn't have a fire warning.

[DSPALLASVI]

Not trying to mimic RL precisely, just involved the 'Fire Detection' system that was not being used in the Sim. It is present, but have not seen it used 'till now...

I have had the fire warning light up on me due to enemy fire more than once, the first time I ignored it after using F2 and seeing no fire, but about 60 seconds later I had an engine failure so I am guessing there was a fire :) Should have autoed.
