Hey, that's a great idea SwingKid, why didn't I think of that? Lock On F-15C: ~34,000 lbf thrust real F-15C: 46,900 lbf thrust Streak Eagle: ~52,700 lbf thrust Lock On F-15C underpowered by: 27.5% Streak Eagle more powerful than real F-15C by: 12.4% Well look at that, the Streak Eagle is a much better approximation of the real thing than the Lock On F-15C! Who would have known. D-Scythe, apparently. For comparison: Lock On Su-27: ~18,600 kgf thrust real Su-27: 25,000 kgf thrust Lock On Su-27 underpowered by: 25.6% Lock On MiG-29: ~14,000 kgf thrust real MiG-29: 16,600 kgf thrust Lock On MiG-29 underpowered by: 15.7% No wonder, we have little problem accelerating vertically in Lock On's MiG-29... -SK

LLTM Lockon Report Last weekend Virtual Aero's Hangar 23 was the theater for the ninth Lowland Tiger Meet. In three sections participants battled it out for the European Championship Lockon, IL-2 and Falcon 4. Because I had little chance to visit the Falcon and IL-2 sections, I'll limit my debrief to the Lockon section. On Thursday afternoon, the door opened for the first participants to build up and have some time for free flight. We spent the entire afternoon setting up the network and configuring the servers for the competition. LigerZero also set up our demo cockpit, which only lacked the intrument panel, because Wasserfall wasn't there yet, and would take it with him on Friday. Build-up was quite slow, as usual, because many people stopped by for a chat, and so it got quite late before everything was working correctly. On Friday morning we arrived early, and had to wait for Ice to open the door He arrived half an hour late due to heavy traffic, so we decided to invade Viper's camper in the meantime. At 8:30 the door opened and the newly arrived participants could start building up. After a few hours of laying cables, helping people set up their computer for the network, and a few minutes of free flight, it was time for the first briefing. The first mission was a mixed SEAD mission, where two teams of 6 had to destroy each other's air defences. Main target was a command bunker deep in enemy territory. For this mission we had Su-25s, A-10s and a MiG-29A at our disposal, the latter for escort and to shoot down enemy attack aircraft. The mission was set up like a short campaign, where the server stayed online between rounds to simulate a real combat environment. Between rounds the teams could use their gathered intelligence data to plot their new strategy for the next round. After the SEAD mission, where I found out the hard way that an S300 is an enemy to watch out for, we had a chance to regain our breath in the next mission: The Airrace. This was a challenge which was inspired by the Red Bull Airrace, where we had to fly under bridges, through narrow valleys and between gates marked by antennas with an Su-25A. The race started at Sochi-Adler, and went through the Kaukasus range, along the eastern boundary of the map, over Kerch, along Crimea over Simferopol, Belbek and Sevastopol, to finally land at Khersones airbase. We had two hours to complete this route. A nice extra challenge in the airrace was that there were no waypoints. We had only the maps we received during the briefing to find our way around. This made flying the track a lot more difficult, especially since there were SAM sites everywhere, which were ofcourse not on the map. Unfortunately the server got progressively slower during the mission because of the number of SAM radars and all the data it had to export for the competition, so in the end precise flying got nearly impossible. After the airrace it was time for the Nighttime BVR mission, with two new teams. For this mission, both teams had five pilots and one GCI controller to guide them. The GCI was an interesting concept I hadn't seen before, and tried my skills as a controller during the first round (which we won!) Just like a reallife night mission, we had to cope with sleep as well, since the mission started at 8pm, and lasted until 1am. The first mission on Saturday was a daytime BVR. This was basically the same as the last mission from Friday, except we had no GCI controllers this time, so now we had to rely on our own radar, and radio calls from our fellow team members. To make our lives more miserable up there, the ground at the frontline was littered with medium-range SAMs, which took me out in all three rounds. Next up was a CAS mission, where we had to clear a corridor to an enemy ammunition bunker well beyond the front line. In this mission I scored my first (and only) kill, of which I'm rather proud since it was also my very first combat mission in an A-10. I didn't have much time to celebrate my kill, since I was hit by an Osa missile from the same site I was attacking, and lost a wing. When the CAS mission was done, we entered the head to head Dogfight Knockout contest. This was a guns-only competition, where the first to win two out of three fights was on to the next round. As our team has never done dogfight practice, none of the Dutch Flanker Display Team pilots survived the first round. We used the extra spare time this gave us to do a crash course in aerial combat. During the lunch and dinner, there were two online formation displays. The lunch demo was flown by the White Ravens, with four of their Su-27 Flankers. During dinner, people could watch the Virtual Blue Eagles perform their show with six P-51C Mustangs in IL-2. This left only one mission for Sunday: the already famous LLTM Airshow. The airshow started at 12pm, and until that time all participants had time to practice a 5 to 8 minute solo display with their favourite aircraft. This gave the audience a nice two-hour airshow, with a variety of aircraft performing, including the Su-27, Su-33, MiG-29, F-15C, MiG-29S, Su-25A and A-10. To mark the end of the competition, all participants still at the event performed a mass take-off and fly-by, before leaving the virtual airspace of Belbek. After the airshow it was time for the closing ceremony, where we had some kind of luxury problem, because there were too many prices. This 'problem' was easily solved with a lottery, after which the winners of each section were announced. When the closing ceremony was over, it was time to pack up, and go for a drink at Virtual Aero. Frazer and I took the opportunity to book a flight in the full motion simulator, which earned me another drink :) At 8:15pm, Scudslaker, Frazer and I were the last to leave. All in all it was yet another perfect event, which went by way too quickly. I've met a lot of interesting new people, on top of the many ones I learned to know in past events, and exchanged lots of information and experience. I would like to thank the people from Virtual.Aero and Tobit for the excellent location and supply of food and drinks for the entire weekend, and of course Jan 'Ice' Hilt for organising yet another wonderful event. Many thanks also to the sponsors Linksys, Saitek, NaturalPoint, Tecpoint24 and the RNLAF 323 Squadron, for their generous offer of prices and making the whole event possible. In a while we will announce the date for the LLTM 2008, which will be the tenth edition of one of the most popular military flightsim events in Europe.

some people can't take a joke :no_sad:

Let's see... A Hub is a device, externally similar to a router or a switch, but that only regenerates the signal. One port receive the signal and it just copy it to the rest. Usually they have 4-8 ports or a maximum of 16 (not recommeded 16). Remember, now we are talking of physical ports, where you plug the connector of the wire (RJ-45 type). Due to this, the bandwith is less. Switches read the packet that arrives at one port. This data packet has inside multiple things, but for now you have to know that it contains the MAC address of the destiny and the data that the application wanted to broadcast. Externally are no differences with the hub (apart of the model and vendor, of course). For home are models from 4-16 ports and for professional are from 24, 48 and ahead. The router are guided by ip's, superior level than MAC addresses, as I told before. How to create a basic LAN manually, so you can control the ip's assigned: ---------------------------------------------------------------------- Now you have two computers wich at least one NIC each. (NIC = Network interface card, where you plug the connector.) Ok, each NIC has an ip, as you see on the ipconfig /all (IP address). Type on a paper or notepad the ip of your computer. Remember, this ip is called private ip. Repeat the step for the other computer. If they begin with 192.168.x.x everything it's ok. It they begin with another, maybe are automatically asigned by DHCP. Don't worry for this now. Ok, now you can see that when you do a ipconfig /all on each computer, they have a default gateway. That's the ip of the NIC of your router. (Two NIC's, cause are routers, not switches). Warning! It's possible that you have only one ip. Don't worry, use this in this case for both computers. (Depends of the vendor / model of your router). We assume you have the internet connection right and can navigate and this stuff. First of all it's enter on the configuration of the router and disable DHCP. (DHCP I explained on the previous post). How to enter? If your router it's relatively new, you'll use a webrowser (IE, Firefox...) and type http://192.168.1.1 or the ip that appeared as default gateway when you did the ipconfig /all. For more info read the manual or check the forums of your contry, sure there are more users that have your same router. Usually the user is 1234 and the pass the same. (You can change the pass easily) Now you have a welcome screen. In my case it shows this: Next step is disable DHCP and assign and own IP to the router (private, not public!). The ip can be 192.168.1.1 (standard ip) and the mask has to be of the type 255.255.255.0 In my case is on this screen: http://d3s1gn.net/lockon/2.png Remember to apply and save. Close your internet browser. Okay, now we have the router with an own and persistent ip, nor an automatic assigned by DHCP :) Time to configure our pc's. The first will have the ip 192.168.1.2 and the second will be 192.168.1.3 Our gateway (the router) is 192.168.1.1 as we have previously assigned. Remember to write your DNS, it's not necessary but always help. Go to your Control Panel of the Windows, and go to the properties of the local area network connection. Dont's know how it'll be in your language, but in spanish it's as the next screen: http://d3s1gn.net/lockon/3.png Ok. Check the tcp/ip and click on "Properties". Next screen will appear. Remember to click on OK. Now you have to repeat this step on the other computer, but with the ip 192.168.1.3 Well.... you have now a manually created LAN! :) Next step is to open the 10308 port on the router. Close your browser (if not done before) and reopen it to ensure the changes are reflected. (Now to enter it's http://192.168.1.1) You'll have somewhere a NAT section, where it has an option of "Virtual Servers". Here you add an application and open the 10308 port (the one that uses Lock On). See screen, and check your router's doc, forums or webpages of how to open ports if it's not similar to the one I have described) http://d3s1gn.net/lockon/6.png Remember to check your firewall software (ZoneAlarm, the one that comes with windows, etc) and allow Lock On to reach the net... Or just disable it if you want. And done! When you understand this stuff of the ip's you'll see it's easier to do a LAN than it seemed before. Easy, easy :) I hope this can help you or someone else. PS: Sorry, I read very well english, but write it's very different. Sorry for all the mistakes.

Anyone of you remember this?

To me, it's apparent that they are flying an aircraft with MUCH more thrust. No, they are qute specifically measuring all the record times from the moment of brake release, as you can see in some of the labels: http://www.ecf.utoronto.ca/~pavacic/lomac/f15climb07.jpg Another one of my favourites: http://www.ecf.utoronto.ca/~pavacic/lomac/f15climb06.jpg Out-climbs an Apollo moon rocket to 60,000 feet :) -SK

Righty - EngineSim's too limited for this estimation. It can't deal with afterburning turbofans, which is probably why they were using the turbojet approximation. As such . . . . you just can't get a decent answer out of it. It'd be possible to work it out theoretically with Excel, but you'd still be relying on guesses in certain places. The furthest I've got is by using the non-afterburning turbofan approximation with: 0.36:1 bypass 1.745 fan pressure ratio (guessed, it was a default ES figure) 10 stage compressor with pressure ratio of 14 (brings overall PR to 25) Fan diameter of 0.88m (from web reference stating inlet dia as 34.8 inches) Which throws out 16,000lbs dry thrust, about 1,500lb more than the stated dry thrust of the F-100. All of which tells us . . . . . actually very little :P Up the speed to 300mph and you lose 2,000lb of thrust, which at least should prove you can't climb vertically in an F-15 without burner. Which was never questioned. Bugger.
