It warms my heart to see the three of them together. Like three brothers. I cant wait to see huge squadrons of LCA and MCA armed to their teeth marauding the asian skies. *Brings tears to my eyes* :)

doubt any PVs will reach active squadrons. trend
is to just retire them or keep as testbeds.

what is the use of those mock up missiles on TD1 and TD2 . Is it just cosmetic or does it have any purpose?

Imagine the same at 600 MPH, at least the hard points are being tested for static and dynamic stress.

I've been meaning to ask... what typically is that stuff on top of the tail? The Rafale seems to have quite a bit of equipment up there too... The F-15 as well.

In addition to the realism of drag etc. the mock up armaments house the sensor recorders also.

Another theory that I've heard before is wing vibration/flutter damping.

The PV1 (KH2003) in Tejas01 looks cool.

I want to give Tejas a nickname -- "PakiKiller" or "KillPak" :cool:

the tail houses radio antennas, ECM antennas, RWR,
IR missile plume detector (?) and someday a towed-decoy.

btw Tejas has already flown its first combat mission. KabirT scored a direct hit on AFM forum.
Harry and others added their share and as dusk was
falling I sneaked in and got my kicks in :D

indian aerospace which used to be 'dismissed' 5 yrs
ago has gained lot of 'respect/good vibes' now.

Rudra, are you sure the tail will house the towed decoy, most other fighters have such decoys installed in the wingtips.

Hi,

This is my forst post.
I have tried to draw and paint a sideline view of PV-2 of Tejas.I am in the process of 'trying' to do a full 3-view picture, in different current and potential camouflage schemes; as suggested by some of the members.
I would appreciate any feedback on improvements or suggestions.I hope the link works.

I agree Nandai based on what Typhoon does. wonder
where the B1 stows its decoy - used over serbia
extensively. the heat from engine might melt the
wire.

Vick that is Sanjay Simha's prerogative - he is enthusiastic and goes places - but tends to find that his best pics appear in the most expensive aviation glossies without his permission, so he is understandably touchy about full size graphics.

Thank You for the feedback Ashutosh! I used 'Paint' software found under accsseroies in Windows 95 on my Pc.Then, i saved the drawing on different formats on my desktop.(eg: bitman, jpeg, etc)however, yahoo doesnt let me upload the drawing in any other format except 'gif', hence my usage of this format! i do not have any other webspasce to post my drawings.
Does the patent still apply in my case?

Since there've been discussion about towed decoys on Tejas, here's a good summary of Western current/planned towed decoys and some of the issues/usages:

Aviation Week & Space Technology: Afghan Operations Underscore Value of Avionics Arsenal
...
Off-board towed RF (Radio Frequency) decoys have been a continuing success story since their use during Operation Allied Force in Kosovo. Raytheon's AN/ALE-50 "repeater" decoy served on B-1B bombers, and was credited with saving several aircraft. The AN/ALE-50 today also serves on F-16s and Super Hornets, and is planned for C-130s, A-10s, and other aircraft. Its self-contained nature makes this a superb system for retrofit, and more than 10,000 disposable decoys have already been manufactured.

Other decoys include BAE Systems' Ariel retractable towed decoy, the most successful U.K. system in service, and the only decoy other than the ALE-50 to see combat. It has been flying on U.K. Nimrod MPAs since 1990, and a second-generation system was deployed on Tornados in Bosnia. A new version, the Towed Radar Decoy (TRD), will be standard equipment on the Eurofighter. BAE Systems also has teamed with Dassault Electronique to develop the towed decoy for the Mirage 2000 and Dassault Rafale. Additionally, EADS, with others, has developed the Sky Buzzer, a fiber-optic towed decoy for German Tornados and large multiengine aircraft. Finally, Sweden's Saab has developed the BO2D for the JAS 39 Gripen and Viggen.

BAE Systems' next-generation AN/ALE-55 Fiber-Optic Towed Decoy (FOTD), developed for the IDECM program, was originally planned to supplant the AN/ALE-50 on many platforms, but delayed development has put this in question. Raytheon is also working on a FOTD and a high-power FOTD, to protect aircraft with radar cross-sections that are greater than fighters. Raytheon and Alloy Surfaces in Chester, Pa., have also been developing pyrophoric flares dispensed from towed decoys to counter IR-guided missiles. This program may be replaced with flares dispensed from a pod instead, however.

While today's plans indicate towed decoys may become almost as common as chaff-and-flare dispensers are now, they are still an imperfect solution. [color="red"]Anything towed from a fighter has a serious impact on its flight envelope</font>, and AN/ALE-55 FOTD tow-line problems are still being dealt with on the F/A-18E/F Super Hornet. [color="blue"]An alternative, however, such as the Cross-Eye from Italy's Elletronica SpA, could provide the same decoy spoofing without physically towing a decoy.</font> Cross-Eye has two antennas mounted, for example, on the wingtips of a fighter. The emission of a modified radar echo from Cross-Eye returns a "wavefront distortion" to the search radar, typically a Surface-to-Air Missile [SAM] tracking radar. The "distorted wavefront" provides incorrect directional information, causing the SAM to miss. If it works as advertised, this approach offers a more elegant and simpler solution by providing an electronically displaced electronic radar echo, rather than a physically displaced one.

But decoys will only supplement, not replace, RF jammers. A major program for the U.S. is IDECM (Integrated Defensive Electronic Countermeasures), BAE Systems' integrated ECM suite for the F/A-18E/F. The U.S. Air Force is developing IDECM for the F-15C/E and B-1B (maybe), and the Navy may buy the associated AN/ALE-55 FOTD for the F/A-18C/D as well. With U.S. procurement of the AN/ALQ-165 ASPJ (Airborne Self-Protection Jammer) canceled, a generation of ECM has been skipped and the U.S. cannot afford to let IDECM slide too much. On the other hand, the successors to IDECM are already under development. The F-22 and JSF will both have integrated EW suites, which will emphasize stealth instead of the active jamming of IDECM.
Typhoon towed designers had to "heat-shield" the optical fiber tow-line of their retractable towed decoy (even when it's being launched from the wing-tips). This is because when a plane does evasive manuevers the tow-line could pass directly behind the engines.

F-18E/F has (in the current version) its 3 towed-decoys launched from almost directly under the engines right behind the center plyon!

So "heat-shielding" is something you can't get away with.

Abhinav, I am not sure if you are not allowed to upload non-GIF pics, for eg, this is a JPG pic I've uploaded to mine.

The patents apply the moment you save it in GIF format. I am not aware if lawsuits have been filed for use of GIFs, however it is best to stay away from that format. And about windoze graphics programs, I am pretty clueless.

Thanks for the clarification. Too bad, the two vixens taking off pic would have been wicked as my wallpaper. C'est la vie, pardon my French. Thanks for all your efforts in letting us enjoy the pics and the movies. And thank you Sanjay! Are you sure you don't need a couple of sidekicks?

I just tried the link, and it seemas to be working.
However, acting on your advice, i will try to make an index page, and link the picture.
at the moment, the picture IS mu index page!!!

Good job, Abhinav. Since you are calling it PV2, it should say 'KH2003' on the plane.

Shiv/cybaru: if you cannot open the link, open a new browser window (not the one which opens when you click on the link) and physically cut and paste the address. There is something weird with geocities but it works this way. Incidentally, the link is directly opening for me.

Until Abhinav fixes the page... for those of you who are still having difficulties:

try right clicking on the link and saving the target page locally -- be sure to rename it with a .gif extension.

Should open up locally then.

Quick question abhinav: the picture shows KH2002 on the aircraft body - isn't that one of the TDs?

[added later]
Okay, I now have a lo-res enlarged wallpaper of the two birds taking off. I will display it as-is on my desktop proudly if I can't get the hi-res. Sanjay, you sure you don't want to watermark a hi-res photo for a wallpaper ?

Both from my Linux default browser and from Netscape on windows the page that loads is a huge page of symbols and gibberish containing the code of the gif - starting with the letters gif87a

I tried copying and pasting this into a text file and saving as a xyz.gif, but copy does not work in both operating systems.

I have not tried M$IE - but knowing Micro$oft I guess it will work so that Bill can pretend that all is well in this world. :roll:

I think it probably would work better if it was a gif linked off an html start page.

PS: yes it works on Micro$oft IE which I am ashamed to admit I still retain for emergencies such as this.

Nice picture.

You are correct Shiv. No luck with Netscape, but works like a charm with IE. Bill accepts all future accolades for integrating GIFs into his browser.
