Subject: Helicopter Function
Hi everyone

I am working Korea Aerospace Inc.(KAI)
My name is Han Suk Baek
  (Login ID is my friend. I Forget My passwd)

We used IADS 6.2  for KHP (Korea Helicopter Project) flight test
Now day, FFRR(First Flight Readyness Review) preparation

Some Rotor Enginner issue Helicopter Function

 How to calculate or processing
     HelicopterFuncs.Average
     HelicopterFuncs.Minimum
     HelicopterFuncs.Maximum
     HelicopterFuncs.AverageLoad
     HelicopterFuncs.AlternatingLoad

someone else provide or explain this function architecture

thank ~~~

It's already in a previous post, but here it is again:

*AlternatingLoad

// HelicopterFuncs.AlternatingLoad( RotorAzimuth, RotorBlib,
BlibTransitionDefinesStartOfCycleVsEnd )
// Alternatively, can be called from Iads as:
// HelicopterFuncs.Oscillatory( RotorAzimuth, RotorBlib,
BlibTransitionDefinesStartOfCycleVsEnd )
// Max( all points during cycle ) - Min( all points during cycle ) ) / 2.0

*AverageLoad

// HelicopterFuncs.AverageLoad( RotorAzimuth, RotorBlib,
BlibTransitionDefinesStartOfCycleVsEnd )
// Alternatively, can be called from Iads  as:
// HelicopterFuncs.Mean( RotorAzimuth, RotorBlib )
// Max( all points during cycle ) + Min( all points during cycle ) ) / 2.0

*Min

// HelicopterFuncs.Minimum( RotorAzimuth, RotorBlib,
BlibTransitionDefinesStartOfCycleVsEnd )
// Min( all points during cycle )

*Max

// HelicopterFuncs.Maximum( RotorAzimuth, RotorBlib,
BlibTransitionDefinesStartOfCycleVsEnd )
// Max( all points during cycle )

There's been a lot of confusion on the third argument
"BlibTransitionDefinesStartOfCycleVsEnd". In the next release I'm going to
simply remove it. Please set the value of the third arguement to TRUE.

Example:
HelicopterFuncs.AlternatingLoad( RotorAzimuth, RotorBlib, TRUE )

If you want some more background info on the third argument, see this link:

Hope this helps,
Jim
