Engine Performance Curves/Equations/Sounds

[P & I Schubert <philings@ozemail.com.au>]

Hello everyone. this is my first post to this list.

A brief introduction:

I am a IT Manager for a the State government railroad in Perth Western Australia.

I recently have been attracted to Linux as an alternative other operating systems that are getting increasingly greedy. As a result I have been interested in a GNU Licensed Flight Simulator that really models aircraft correctly and have just recently commenced contributing the FG project doing work on accurate engine models.

I am not new to Freeware concept having released a comprehensive donationware scenery package for Flight Simulator 98 covering the complete state of Western Australia (about 1/3 the size of the continental US). There have been about  11,000 downloads of this scenery for he various site world wide.

It is available from http://ozpack.pcsa.net.au/AWA.html

Screen shots of my next release can be seen at:

I have 4,500 hours command time as a commuter airline pilot in the late 70's early 80's before taking up computing as a profession.

Anyway, I am chasing engine performance curves for a variety of engines. So far I have good data on Continental IO-520's, some on a PT6A-27, but looking for data on Lycoming engines, as well as Biz Jet engines.

Aircraft operating Handbooks are a good source, as I can plot points on the graphs and then do regression analysis on these.

Also looking for sound recordings of starting , idling, runnups, take off, and shutdown power settings to build into these models. Any format acceptable. These recordings would need to be in good quality mono, and preferably stereo.

These are particularly important for the PT6 engine.

Anyone handy to an airport?

Thanks in advance
