Re: Beagle Pup Development [crossposted]

A couple of new commits:

0.27.0: Electrical panel and updated electrical system. Improved internal lighting. Pretty much all switches work now.
0.28.0: Pitot icing reduces pitot pressure and eventually blocks the tube.

Re: Beagle Pup Development [crossposted]

I've just committed 0.26.4, which has a few bug fixes to my Aeromatic++ FDM and engine related matters. For the time being, that's my FDM. Take it for what it is which is a vanilla Aeromatic++ FDM tuned for performance in a normal flight envelope. I will revisit it at some point, probably using Java...

Re: Beagle Pup experiment

@Richard: I was looking for some photos to do some cockpit modelling and I stumbled upon this:

http://www.airport-data.com/aircraft/ph ... 09860.html

It's probably the best photo I've seen for measuring the dihedral angle, which I get as 5.8 degrees.

Where does Jomo put his videos these days?

I looked here, but they stop at July 2016: http://www.emmerich-j.de/EDDF/Films/Films.html

Re: Beagle Pup experiment

The particle system is the only way I know to do it. You should read the notes at the top of the Wiki page and the persistent contrails link. It was only quick and dirty in the sense that I nicked it from another aircraft (737-100) and it may be configured (particle size and so on) for vapour rather...

Re: Beagle Pup experiment

Don't worry about the trim offsets, I know what they are -- I was experimenting with fixed trim tabs. Smoke -- I suppose you'll be wanting different colours on each wing too? :roll: https://dl.dropboxusercontent.com/u/2838854/Pictures/fgfs-screen-249.jpg EDIT: Base version with generic autopilot and...

Re: Beagle Pup experiment

Look at mine for the structure I have similar structure contacts but I'll double check the positions and try using your numbers. Is it likely to be the damping that makes it go wrong? To be honest, I don't know if it still has the pinging behaviour. I think I read somewhere at the time that it was ...

Re: Beagle Pup experiment

its game over. Indeed. You didn't specify a forward velocity and it would appear that, somewhere between Aeromatic++ and JSBSim, the model become mathematically unstable. This is not entirely surprising, given that an aircraft at altitude with no forward velocity is not a normal flight condition. I...

Re: Beagle Pup experiment

it seems G-SHOZ added a subroutine that mimics the "you've lost a wing" situation, cause I certainly hit nothing at 10000 feet with no traffic to collide with. Part of the crash detection system listens for extreme G forces, something I adapted from Hvengel's P51D. It's not simulating dam...

Re: Beagle Pup experiment

You went that way out of Innsbruck on a 100hp engine! :shock: :lol: Thanks for testing. So about 25 minutes to get to 10,000 from 1,900 and 40 minutes to get up to service ceiling. That's in the right ballpark. When I have a half hour to waste, I'll log a climb from s/l to 10,000 (which should be ~3...
