  1. I've had both FS2004 (aka FS9) and FSX run fine on both Windows 8 and Windows 10. The problem comes with some of the addons.
  2. Sometime last year a nifty little freeware programme for X-Plane was released called Ortho4XP. It lets you create your own photoscenery using publically available data and orthographic imagery. I started poking around with it last month and was impressed by the results. I've now got all of Great Britain covered with ZL17 (1.2m resolution) photoscenery and combined it with the excellent GB Pro object placement scenery. Here's a sample of how it all looks: What's more I didn't have to spend a penny on this scenery. Pretty impressive really!
  3. Thanks Neu, some interesting points to ponder. I'll write more tomorrow when I get a chance.
  4. Remember when India announced it had selected the Rafale for its MMRCA requirement? At the time it was said that although both Rafale and Typhoon met the technical requirements, Rafale was significantly cheaper and as such was selected. Quite a few eyebrows were raised at this and there was some speculation that Dassault had bid way below cost. Well check this out: http://www.dnaindia.com/india/report-dna-exclusive-100-price-escalation-on-rafale-fighter-aircraft-to-rs-175-lakh-crore-likely-to-dent-iaf-s-strike-capability-1957107 Sources in India are saying that the cost of an Indian Rafale
  5. I think that the AoA would only need to be increased to achieve the same lift if the true airspeed remains the same? The same indicated airspeed would yield the same AoA if all other factors were the same. I may be wrong though? Critical Mach, that sounds pretty plausible, and you're right this would be achieved sooner at higher altitude.
  6. The problem there being that the AWACS will be sitting pretty deep behind lots of air defences and pretty hard to get to. The Russians have some interesting ideas though involving very big missiles which home in on the AWACS' radar emissions... whether or not they can take them beyond a model at a trade show is another matter. I also seem to remember reading a few accounts of some upsets in exercises when the RAF contingent got uncomfortably close to the enemy AWACS. There is a train of thought that AWACS may be of less importance in the future, with the amount of datalinking going on it's p
  7. I even manage to win an argument with my wife on occasion! I'll have a better look at some of the other articles in that blog later, you may very well be right. To be fair I do think the Americans spend an unnecessary amount of money (to put it mildly) on defence, but as you say that's political and another discussion entirely. Still, I always find such dicussions interesting!
  8. Check out the F-22's air intakes and the leading edges of the wings and tail surfaces when it turns towards the camera. As I've said already, whatever you make of the motives or indeed bias of the blog - the physics can't be argued. Sitting up in the stratosphere, with no clouds or precipitation, travelling around with two 160kN class engines and frictional heating of the airframe.... with an atmospheric window between 3 and 4 microns where IR atmospheric attenuation is only 10%...... it doesn't take a massive stretch of the imagination to see that an aircraft like the F-22 could potentially
  9. Perhaps you misunderstand what I meant by "vintage". I wasn't inferring the aircraft were old. However, I'm sure you are aware of the Soviet practice of exporting downgraded so called "monkey models" to non-Warsaw Pact clients. Downgraded radar, weapons, defensive avionics etc. In the case of the Serbian MiG-29s in 1999 they had been starved of spare parts for years and were flying with no functioning radar or radar warning receiver. As for the blog I linked, I agree there are quite a few things in the blog I don't agree with. As you say, much is made of the AIM-54 which I believe was a somew
  10. On the subject of using an IRST to detect F-22, check out this video: http://www.youtube.com/watch?v=PLzD1SCk__g Note how little difference there is between the Typhoon, F-16 and F-22. Also note the massive heat plume when the F-22 uses its reheat. Now have a read of this, as it explains fairly well what I've been trying to say all along: http://theboresight.blogspot.co.uk/2009/07/airborne-infrared-and-supersonic.html
  11. I agree a ballistic missile has a huge IR signature, but remember it was 400nm distant. If you want to break it down to horribly simple and apply the inverse square law, the ballistic missile at 400 miles is 8 times more distant than the fighter at 50 miles. That means the IRST would be getting 1/64 or a bit over 1.5% of the IR radiation it would be getting if the ballistic missile were at 50 miles. That doesn't take into account the atmospheric attenuation which should mean even less of that IR radiation would make it from the ballistic missile to the IRST. As you say, 50nm for a fighter size
  12. I'll have to take your word on F-22's IR reduction measures, but I'm far from convinced. 90nm+ for an AIM-120D would be under ideal conditions and a non-manoeuvring target. I suspect the PK against a manoeuvring target running with a modern defensive suite at this range is rather poor. BTW, forgot to tell you that I absolutely agree with your comments above about Typhoon being very expensive and a poor multi role choice. I'd go further and say the failure of the partner nations to get off their backsides and develop Typhoon to meet its potential in a timely manner has almost certainly cost i
  13. To be honest I don't know a lot about infra red attenuation in the atmosphere, but the German guy reckons there are two wavelenghts where attenuation is reduced and these are "atmospheric windows". I'd have to read up on it to get a better idea though. If EODAS on F-35 can detect a ballistic missile at over 400 miles then I don't see why PIRATE can't detect a fighter at 50 miles. The bad weather and atmospherics have been raised before, and again the counter point is you don't get much in the way of cloud or rain at the stratosphere where these aircraft would be operating. I absolutely stand
  14. Back in September when I was doing my Chief Engineer's ticket there was quite a heated discussion in the classroom about how torque is transmitted to the ship's propeller - is it via shear in the coupling bolts or is it via friction between the coupling faces in the transmission line? Nobody could agree so the lecturer contacted a couple of companies that make power transmission components for ships and asked them. A design engineer at one company got in touch and explained that the torque transmission is around 85% shear, and 15% friction. It reminded me a lot of the Bernoulli vs Newton arg
  15. Graham I think you might be right about the engine having quite a lot to do with it. I think the Sabre only had a single stage supercharger? Like I said, I had problems reconciling the popular reasoning that the Typhoon was a poor interceptor because of its performance limiting thick wing, yet at the same time it was faster than the Spitfire V at low altitude and the only RAF fighter capable of catching a Fw190 in 1942. Be careful about attributing aerodynamic lift to Bernoulli.... Newton has got a say in it as well. Otherwise aeroplanes couldnt fly level upside down
