Re: [Flightgear-devel] Control FlightGear via external application
Artem, You might want to consider using JSBSim instead of FlightGear. I think you'll find it a lot easier to work with. Lee Artem Chernodub wrote: Hello to everyone!

FlightGear is a perfect testing area of control algorythms, because it is complex flight object. So, I need a way to connect to FlightGear, but I don't understand how to do this.

Re: [Flightgear-devel] airliner ditching miracle ... or not
I don't want to take sides in this discussion, I just wanted to share some information about the Controlled Impact Demonstration (CID)--or as it was known at Dryden, Crash In the Desert. The story of what happened depends on who you talk to. I remember that the FAA was not very happy with the crash. Dryden folks seemed to think it was very successful. Having been there and somewhat involved in the early stages of the flight test program, my personal assessment is that the pilot screwed the pooch on this one. The following is from the Dryden web pages: Controlled Impact Demonstration (CID) Aircraft In 1984 NASA Dryden Flight Research Center and the Federal Aviation Administration (FAA) teamed-up in a unique flight experiment called the Controlled Impact Demonstration (CID), to test the impact of a Boeing 720 aircraft using standard fuel with an additive designed to suppress fire. The additive FM-9, a high molecular-weight long chain polymer, when blended with Jet-A fuel had demonstrated the capability to inhibit ignition and flame propagation of the released fuel in simulated impact tests. Antimisting kerosene (AMK) cannot be introduced directly into a gas turbine engine due to several possible problems such as clogging of filters. The AMK must be restored to almost Jet-A before being introduced into the engine for burning. This restoration is called degradation and was accomplished on the B-720 using a device called a degrader. Each of the four Pratt Whitney JT3C-7 engines had a degrader built and installed by General Electric (G.E) to break down and return the AMK to near Jet-A quality. In addition to the AMK research the NASA Langley Research Center was involved in a structural loads measurement experiment which included having instrumented dummies filling the seats in the passenger compartment. Before the final flight on December 1, 1984, more then four years of effort passed trying to set-up final impact conditions considered survivable by the FAA. During those years while 14 flights with crews were flown the following major efforts were underway: NASA Dryden developed the remote piloting techniques necessary for the B-720 to fly as a drone aircraft; General Electric installed and tested four degraders (one on each engine); and the FAA refined AMK (blending, testing, and fueling a full size aircraft). The 14 flights had 9 takeoffs, 13 landings and around 69 approaches, to about 150 feet above the prepared crash site, under remote control. These flight were used to introduce AMK one step at a time into some of the fuel tanks and engines while monitoring the performance of the engines. On the final flight (No. 15) with no crew, all fuel tanks were filled with a total of 76,000 pounds of AMK and all engines ran from start-up to impact (the flight time was 9 minutes) on the modified Jet-A. The CID impact was spectacular with a large fireball enveloping and burning the B-720 aircraft. From the standpoint of AMK the test was a major set-back, but for NASA Langley, the data collected on crashworthiness was deemed successful and just as important.

Re: [Flightgear-devel] Object avoidance
Has anyone tried integrating this radar with standard terrain models such as those from the DMA? Also, it seems that integrating a realistic radar simulation feature into FlightGear is valuable even if it runs a little slow, because having such a model would provide developers an open source, low-cost platform for testing TF/TA systems. I can certainly imagine many uses for such a feature with the emergence of UAS for so many applications.

And I'm not sure if they collide with static/random buildings. They hardly do with trees. Hmm ... cows? m. Markus Zojer has used this technique for the TFA functions in the B-1B. I had a look at it and experimented with it when I wanted to add TFA to a couple of aircraft I've done - it's a very appealing approach because it's almost like simulating a real radar. I had a play with the technique but hit some problems with it, mainly because the trajectory of the submodels is fixed to the pitch of the aircraft. I found it fine while the aircraft was in level flight but I hit some issues when the aircraft was pitched up or down to any significant degree and in the end I decided to use the Nasal geo functions instead. I am still working on the terrain following function, rewriting it completely for the 3rd time and again used the real radar approach, as you are not dependent in the scanning resolution of the geo properties. The fixed radar beam (submodels) could be refined if we would add the property absolute to the pitch angle of the submodel (so the submodel leaves the plane at always the same pitch angle). Due to the ongoing environment development in OSG, now low level flying is really flashing :) Expect the new version included in the next release (coming hopefully within the next 10 days). Fly on, Markus As I mentioned previously, the geo functions do interact with static buildings and structures, as long as the scanning scheme has a high enough resolution to ensure sampling them - I haven't tried with random objects though - still on OSG 2.2 here and the performance hit when using OSG_DATABASE_PAGER_DRAWABLE=VertexArrays is too great here. I have noticed that pylons are not detected and I would doubt that trees are detected either, presumably because they have no area. The pylons are made with line objects that have no width and the trees, at least in plan, also have no width, so it'll be very unlikely to hit the exact point where they are in any scanning scheme. Adding a transparent horizontal plane poly to the top of these objects probably would make it work, but not only would it increase the render load but also probably introduce more transparency render artifacts and ordering issues. OK I can give you submodels which are stabilised in pitch within a few days, if this is really a good approach - submodels are a big frame rate hit. Would an alternative be to duplicate the code which calculates the ground intersection for submodels, without the cost of flying the submodel? This approach would take more coding, but might be less frame rate intensive. However, the methods which are used are some of the most frame rate heavy around so perhaps in practice not too different. Vivian It is an attractive approach because it is very similar to the way that real radar works and it's fun to add a visible model to the pulses so you can see them:) Some of the problems I found with it though, include the high submodel overhead. Even in level flight I found I needed to 'fire' pulses in a vertical fan, both above and below the line of flight, to ensure detection of higher ground, especially if the aircraft is pitched down to any significant degree. However, if there isn't any higher ground within range, which will be the case unless you only fly in mountainous regions, a high proportion of the pulses will never hit anything and will only expire at the end of their lifetime - this seemed like an unnecessary overhead. I also hit some problems with the resolution of the pulses, this seeming to be tied to the pulse speed, the aircraft speed and the frame-rate, because the location of the pulse can only be checked once per frame. For example, if you use a pulse speed of 1m/s and you are running at 20fps the

We could go with 0.10.0, but then all the odd/even version number proponents are going to come out of the woodwork, and that is going to mire in it's own set of politics. We could go with v1.0 ... we've been at this 10 years, and averaging 0.1 versions a year isn't so bad. This is my preference. FlightGear is developing at a rapid rate, but if we stick with 0.9.12, 0.9.13, 0.9.14 it seems like we are bumping along with very minor increments every few (or many) months. Of course this all boils down to marketing. Who cares what the actual numbers are really, as long as they increment in a sensible way. But what image do we want to project to the world? Are we a bunch of old cranky developers (it looks that way sometimes!) :-) inching along at a snails pace, or are we a dynamic exciting group with fast paced development continually adding new and exciting features and aircraft? We've been at this 10 years, have we really only managed a 0.9.x release in all that time? Again, not that version number really mean anything, other than to project our image to the world.
