  1. Is it me or am I imagining this

    I really must be imagining this but I have noticed a trend that with the increase in price of a car the stupider and more callous the driver.

    A few minutes ago I just shagged a Bently (I'm so impressed NOT) out of my clearly marked Handicapped parking space. Before I did got a snapshot of the plate thats all I need for him to get a minimum 250 dollar ticket here in NH. Yeah chump change for a dick who owns one of these but there is a point here. Folks the Handicap spaces are there for good reason and I sure as hell hope none of our crew abuses them. Folks like me really need those spaces much as I wish we didn't but that's life. Anyway here is the Dickheads plate

  2. How come (as i never seen and searched return nothing) i havent seen nobody talked about this chopper:

     

    Kaman Sh2 SeaSprite/Super Seasprite

    Lynx1.jpg

    sprite3.jpg

     

    Ive been reading about it and his use in Vietnam as Gunship and it has an interesting history...although, nobody seems to like it . :wink:

     

    Opinions please.

     

    Do a search under LAMPS (Light Attack Multi Prpose System) they came in about three flavors. Mostly the LAMPS was developed to give Heli born ASW and some S&R capability to smaller surface platforms that could not carry the larger Sikorsky heli's. FF like the Reuben James and such carried LAMPS some versions had MAd and sonobouys others had a dipping sonar. A few had a 7.62 chin mounted mini gun but this varient was very rare Spain had a couple with this on the old Didalo I saw this varient up close while in port in Rota back in 1977.

    By the Way Kamaan Heli's is located inCt. and the worlds first turbine powered Heli was devloped by them. It was the flying test bed for the old Husky with the intermessing rotors and was on display for many years at the New england Air museum at Bradley International Airport . Back in the mid 90's Kamaan took the Heli back and developed the Aerial logger from it to replace the display heli they gave the museum the only known flight capable Husky left in the world.

  3. One: is it realistic 800 knots with external tanks at sea lvel? the f-15C makes 680 tops

     

    second; wasn't there a project for an external pod with the avnger gun ? if so it is includd in the weaponpack?

     

    thanks

     

    If I recall in real life the only thing that ever came close to this at near sea level was the old Thud F-105. I recall reading in Air combat years ago during a Red flag they dropped to ground level and just ran away from the F-16's and 15's with ease. During this they were given the nickname "Land Shark" as the distinctive tail was like shark fin sticking up above tops of some terrain they were masked in.

    The Thud was designed primarily as a high speed low level penetration nuke strike bomber with ATA to fight it's way out . It followed the classic fast bomber rules... just like the original Marauder of WW 2 BIG engine BIG gas tank minimal wing! But as always as times changed the aircraft was modified for other roles.


  4. Playing around with Zur-Techs nice MV-22B was a lot of fun but lacked something.... A ground attack capacity likr the ones in Dale Browns novels. Looking at the F-5A I did a rough comparison of weapons locations and thought the locations for the inner wing pylons was close to the gear pods on the V-22. So I copied and transfred that info over to the V-22 and made the apropriate change in the rest of the Data and changed the allowed weapons to just GP,RP and CGR. When loaded the pods rest very conveningly on the top outside edge (just recessed enough to look right) of the Gear pods and behind the leading edge of the wing. The line of fire is just inboard of the prop arc and looks like it was designed this way from square one. And two Bull Pups makes this a bad ass looking bird!

  6. Typical Airbus accident. They have computers that automaticly override or make critival flight decsions that sometimes countermand or conflict with normal operations of the aircraft. Most likely this was one of the computer decsions that automaticly releases the brakes at a takeoff throttle settings. This feature is on ALL airbusses to prevent the pilot from overstressing the airframe on the ground. A famous crash of an Airbus took place when the computer delayed the pilots throttle command by 10 seconds and overrode his full up control input. thats the one where it flies into the woods at the end of th runaway during a slow low pass. I was working at PWA at the time and the series 4000 has FADEc witha spool up safety limeter to keep the compressor from stalling it spools up the engine as fast as it can without stalling it. Airbus thought this spool up was still to fast and added another delay to slow the throttle response. They tried blaming PWA but PWA proved thay had tampered with the FADEC programing the spool up time. another incident witha A380 happened in Bermuda wher the computer kept overiding the pilot during apporach and auto engaging the go around. This happend for two hours until the palne went dry and they glided in. Airbus airframes are not safe at all! I will not get on an Airbus and have canceled flights to stay of them.

  8. Okay I've heard more then enough of you arm chair Fighter pilots. I worked on the Prototype F-119-Pw-100

    Engines for the F-22 so I have a damn good idea of what reality is as far as this airframe goes.

    First Helmet sights are all well and good BUT with these cavets....

    Sure you can get an initial lock on a raptor or any stealthed aircraft BFD unless you have an active data link to the weapon (missile) that is absoulutly jam proof that first lock doesn't mean s**t. Once the bird leaves the rail it's on it's own and are subject to the inherent design features that make a lock so hard to get on a Stealthed aircraft even more so as Radar guided weapons by shear size cannot carry the same order of power radar as an aircraft, IR signatures by nozzle design and other features of a stealthed aircraft are suppressed,laser guided weapons need a beam held on the target until impact and in a dogfight if your target fixated your gonna get zeroed by another fighter especially if this laser is guided by a helmet site. Even more so what good is it going to do you if you see the bird and it is out of both your gun cone and weapons launch envelope not to damn much.

    Given the advance in threat warning systems a stealhted aircraft with the manuver capbility of the f-22 Raptor /F-35 Lightning unless the pilot is asleep at the switch is going to be a very tough opponent no matter who the enemy is.

    Stealth and super or hyper manuverability has now made Air Combat more like Submarine warfare where if you can see them or hear them before they hear or see you you win.

    Further no matter what the equipment the better pilot in a given situation is going to prevail.

    I read in this thread "the f-15 has never faced an equal in combat" BULLs**t ask Fighter pilots from Isreal and in the first gulf war F-15's went up against the Mirage F-1 and 2000's along with Mig 29's all three equal to the f-15 and f-16 on design anyway. The difference is training and the will to prevail. Even better in red flag f-15's, f-16's and f-14's had a hell of a time against F-5's and when faced with F-105's the 105's played land shark got low and out ran the F-15's and F-14's and leftr the 16's gasping for air.


  9. Just So Kirsten. I often wondered what a newer technology F-8e with upgraded avionics, improved powerplant, new wing and a better gun to match would do for my selfish flight sim needs.

     

     

     

    :ph34r: CL

     

    Well you could model the F-8U-3 Super Crusader that lost to the F-4. It was a political infighting thing in the Navy that caused the F-4 to be chosen mostly the Missle only attitude and the ATG bomber capbility built in this way the Navy made the penny pinchers who hobbled the TFX program happy.

    To damn bad the F-4 was picked The F-8U-3 kicked it's ass all over in everything except carrying bombs and having guns.

     

    The F-8U-3 Super Crusader

     

     

    One Pratt & Whitney J75-P-5A/6 turbojet, 16,500 lb.s.t. dry,

    29,500 lb.s.t. with afterburning.

     

    Maximum speed 1457 mph (Mach 2.21) at 50,000 feet, 800 mph (actually brushed Mach 3 in flight testing)

    (Mach 1.05) at sea level. Cruising speed 575 mph. Stalling

    speed 154 mph. Initial climb rate 32,500 feet.

     

    Combat ceiling 51,500 feet, service ceiling 60,000 feet. Combat

    range 645 miles.

     

    Maximum range 2044 miles. Maximum fuel 2036 US

    gallons.

     

    Weights: 21,862 pounds empty, 32,318 pounds combat, 37,856

    pounds gross, 38,772 pounds maximum takeoff.

     

    Dimensions: wingspan 38 feet 11 inches, length 58 feet 8 inches,

    height 16 feet 4 inches, wing area 450 square feet.

     

    Projected armament was to have been four 20-mm cannon plus three

    air-to-air missiles carried in slots cut into each lower side of

    the fuselage and on the fuselage belly just behind the forward

    landing gear.


  10. The Crusader had the same engine as the Hun, and it outperformed the Hun in almost everything!

     

    bibbolicious, nice skin! What terrain is that?

     

    Actually the Engines WERE NOT THE SAME. While the base core was the J-57 from PWA the varients and thrust rating were different with the F-8 having higher thrust verients. It's a common misnomor that just becasue and engine has the same designation at the begining that they are the same for the different varients. In most cases until PWA introduced the module concept in the early 70's only about 50 percent of parts were interchangeable between varients of the same engine family.

    And until the F-14,15 and f-16 programs Engine mounts and plumbing connections were often different between engines of not only the same family but builder. With the comon engine bay introduced by these programs this all changed and plumbing setups became standard between airframes and engines.

     

    F-100

    Varients before the F-100D had the

    J-57-P-7 rated at 10,200 dry and 14,800 Wet

  11. 7z mix of GNU and BSD, my bad!! :dntknw:

     

    I don't know where to get the -28 bomber version. I forgot. If I get the WoE, I'd add it to the game (F-5A too, assuming emergency mass production in that scenario, should be Awsim fun).

    this si the link for the Brewer Bomber version IMHO a far more potent aircraft then the base Firebar it was moded from.


  12. Fellow fliers I had to reload my SFP! and WOV programs after my wife accidently wiped the harddrives they were on.

    Don't ask the woman is a menace around electronics. i have been able to find and downlaod nearly all the aircraft i had with one exception the Yax Firebar. It seems this has disappeared in the all the various websites. If anyone has the flie it would be greatly apreciated.

    Thanks All I forgot about Major Lee's airdrome!


  13. TVC was not part of the ATF specification. The F-22 didn't HAVE to have it, LockMart put it in anyway to make it better. NorthGrum went for extra-stealthy and didn't.

     

    Keep in mind that from what I've read BOTH planes satisfied the "plane" part of the ATF competition. The F-22 wasn't a "better" plane than the F-23 to any significant degree. Instead, LM won on the other parts of the competition.

    In short, the USAF believed LM was more likely to deliver the F-22 as advertised, with the least troubles, and cost growth and so on. They had less confidence in NG's ability to execute the F-23 program to the same degree.

     

    Actually, I think it safe to say that had NG been the one making the F-22 and LM the F-23 that in that case the F-23 would have won!

     

    This is true as far as the TVC but the Air Force did weigh that into the evaluation formula in stating it would be a bonus. HOWEVER the winning engine from Pratt was designed from square one to have TVC. It was designed with the universal mounting sytem to allow it to be back fitted to F-15's in case the ATF was completely killed off. If one digs into the history of the F-15 it was designed to have TVC but the materials technology for the petals was not adequte to handle the flight loads at that time (1973). I was heavily involed with the ATF engine program at Pratt during the early 90's. Pratt by the way was able to deliver ahead of time the flight engines while Ge was late by several months delaying the whole fly off the airforce waited for them even though the F-22 and 23 Protypes with the Pratt engine were ready to go. The 23 flew first with PWA's and the F-22 First flew with the GE's the Airframe to fly first was chosen on a coin toss. And by allowing GE to fly the second airframe first was a bone thrown thier way. Their "Dual cycle" engine had real problems from square one. As far as IR signature went a lot of it was due to the PWA's exhaust temp being much lower then the GE's which had a lower bypass ratio due to the "Dual cycle" design which was intended to act as a turbo fan at takeoff and midsonic ranges and then switch to a turbojet cycle at high speeds were they are more efficent in theory then a turbofan.

    Another thing that hurt the XF-23 was wingtip contrails. During fairly moderate G loads during a turn the inner wingtip would forma huge wingtip vortex contrail that magniifed the RCS. Plus was a big visual hint soemthing was there. As well the weapons bay was non functional as far as being able to mount and launch a weapon during the flight test program while not required the YF-22 had a fully functional weapons sytem on board and did launch both a sparrow and Sidewinder during the eval program. The YF-22 also had a fully functional aerial refueling system when flown and did tankoff from a KC-135 while the F-23 could only simulate this. Later the second PWA powered 23 's refuel sytem was succesfully tested during late eval flights.


  14. Another engine was also tested in the same fashion using dynamic compression to hold the flame front and control the exhaust expansion. Simalar to the Aerospike engines that came out of the NASP program. And yet a third confgiuration was also developed. In any case the plan was to use F-100 cores to provide takeoff power and inital igniton to the "Second Stage"cruise portion of the propulsion systems.

  16. hehe thanks. Got screenshots?

     

    30,000 feet? pffft :biggrin: 30Mt cloud tops out at maybe 150,000 feet, and lasts for a few hours game time. I'm slightly increasing the effects here, for an update. You can make the small yield effects far more detailed for tactical ops, but I assume dozens and dozens of these large cloud formations be visible across the map under a strategic warfare environment, so I try to economize on the number of "emitter particles" and stuff.

     

    Tip:: Something I naturally "forgot" to include in the install advice ... you can ramp up the game's external Free Camera altitude limit of 100,000 feet (if I recall that). Its in the FlightEngine.ini file. I set mine to...

     

    [WorldSettings]

    SectorWidth=20

    SectorHeight=20

    SectorMaxObject=256

    Border=20100

    MinHeight=0.5

    MaxHeight=1E+6

     

    Thats in meters, thus, for me, 1000km. And to make use of this extra distance, scale up the camera translation speed/acceleration. Advice for that are in the Add To FlightEngine install advice. At least I remembered to include that. I also "forgot" to put in the ThirdWire webboard link...had the "~>" dropped into the file, but I didn't include the link. I'll do it here...

     

    Linky ~> http://bbs.thirdwire.com/phpBB/viewtopic.php?t=3970 ... I could use some critiques and advice.

     

    More info I "forgot" to offer -- In all the nuke effects files, ALL lenght values (all distances, Emission Volume, etc...) are in meters, often with "calculator style" scientific notation of E+3 to readily allow mental conversion of the base to kilometers. Times are in seconds, Table-Time values are decimal fractions of particle lifetime. Emission Rates are not rates but their multiplicative inverses (time periods), in seconds, between particle emissions. I'm not sure what units the Emission Velocity uses, but I played with values until it seemed to work for me.

     

    For those thinking of using the nucks in WoE campaign, if it can handle them, think of adding MontyCZ's Yak-28 bomber. Its at colum5's pure Cold War downloads, on page 3 ~> http://www.column5.us/aircraft.shtml

     

    Somebody was working a TSR.3 (or was it .2?), you know the cancelled British supersonic bomber. F-111 may also be useful in WoE.

     

    F-111 series by the Vark Team is available at CombatAce. Amazing F-111 cockpit by Mike Werner here ~> http://www.schmidtwerner.de/products/f-111_pit.html

     

    I always thought F-5A and F-5E would be interesting additions to WoE, its also at C5's pure Cold War downloads, and with a very immersive pure daylight fighter F-5 cockpit.

     

     

    Lexx

    I installed the files made the changes as called for and it doesn't work in SFP1 with all the latest up dates on my system. I haven't tried version 1.1 yet .


  17. This is fantastic. I always thought the YF-23 looked like a more dangerously mean piece of work than that poncy YF-22, so I was a bit disappointed when it lost the contest.

     

    Thank you very much.

     

    The final design chosen( the F-22A) was based on several facotrs most of which are classified. However two of them that are not were the Raptor incorporated Thrust Vectoring which due to the design of the 23 was impossible to incorporate. The advantage of VIFF was proven during the Falklands War by Harriers. Another thing that counted against the 23 was during even modest gee turns there was a huge wingtip vortex contrail on the innerwing tip which the Raptor does not have this contrail defeats the visable aspect of the Stealth design. I mean seriously if you see a contrail appearing out of nowhere wouldn't that give you a heads up something was heading your way?


  18. I was of the understanding that both ATF and JSF designs had wing hadpoints incorporated into their designs to allow for ferry tanks? That's why defence analyst's here in Oz are pissy about the JSF (as well as for many other reasons) as it will need external hardpoints in order to approach the F-111's service profile which kinda defeats the purpose of buying a multirole strike platform to replace a dedicated long range strike platform. The plan was to operate F-22s and JSFs in either clean (no externals, lower radar return) or conventional profiles depending on the environmental situation wasn't it? Or is that still being debated?

    Oh, this if the current profile of the F-22 with externals:

    http://www.fas.org/man/dod-101/sys/ac/f-22.htm

    Ps. ^^ Working on prototype fighter programs... sweet work if you can get it! :tongue:

     

    When I was involved with the program the prototype did not have hardpoints as at that time there was no plans for a multi role varient. The F-22 was orignaly designed a pure fighter. I would imagine at some point a conformal tank being designed for it as the F-15's have to replace the very observable externals.

    IMHO the JSF is a flash back to the origanl TFX program one airframe for all services which lead to the 'Vark. Sure it meets the need for a Harrier replacement, but is to short legged to replace either the 'Vark or Falcon. I really feel as far as the USAF goes by buying both airframes Raptor and Lightening 2 it is wasted funds. I'd rather see it all spent on F-22 varient develoment aimed towards a direct F-15E replacement long range strike heavy payload and fairly low observables.

    To my mind the USAF JSF varient should be killed off along with Ospery a very troubled program over 16 years in creating and it still isn't ready? Talk about waste.

    This is the F-23A Black Widow II as if it had won the ATF competition.

     

    There is no cockpit, so it uses the in game F-4E cockpit by Thirdwire. Hopefully I'll ba able to do one in the future.

    Hate to say this but....

    Nice to see it modeled but there are some real BIG errors in it. I worked at Pratt & Whitney Aircraft during the development period of the ATF prototypes in R&D on the ATF engine program so I really paid close attention to the ATF flyoff when it happened.

    The engines selected was Pratt & Whitney F-119-PWA-100 NOT the GE-120. GE was nearly three months late getting their prototype dual cycle engine working. In fact the GE prototype powered flight item was supposed to be the first to fly but due to GE's problems the PWA prortotype powered item flew first. The GE engine delivered more thrust BUT was far more thirsty and had a much larger thermal footprint. The PWA protype only needed a slight fan Dia. increase to make up the thrust difference. The GE needed far more work to be a viable production engine and had a higher cost. Winner of ATF engine contract PWA!

    The F-23A HAS/HAD internal weapons bays like the Delta Dart and F-117A as does the F-22A neither aircraft was ever meant to have wing racks and exteranel rails as these destroy any stealth radar features they have.

    Sorry for being a nit picker but remember this program was my living at the time.
