f16 xl a more advanced wing design yet concieved with a higher payload, a cranked areo delta wing platform
f-22 conventional
f-35 conventional
t-50 conventional,
see the pattern.
your argument is mute
you have no scientific basis.
Can you tell how conventional was F-22? How do you define conventional? Any preceding plane that looks like F-22? What is conventional design? How does it look lie? Who can authoritatively claim a design is conventional ?
The lca projects consultant was dassualt, that time dassualt was working on the rafale and tampering with new delta designs. India concieved a cranked delta design, as seen in this thread, even did wind tunnel tests.
but the future for the lca tejas changed when in the early 90's the cranked delta design was tried on the f-16xl, one of the designers was indian.
the cranked delta was used in the US space shuttle as well.
it provided with key advantages,
lift greater than the conviental delta on mirage 2000 series.
unstable design, hence the tejas is "statically" unstable.
which means, even with out tails or canards, the lca is unstable and unable to fly with out fbw and computers. the entire wing design is creating drage upward.
Now India conceived the 'cranked' delta configuration? So if I cranked the F-22 wings a little, I get a 'cranked conventional' design? how much degree you need to crank to be called a cranked delta? How did India conceived this 'cranked' design? if India conceived it, what were the French doing there? Look at you conceive while getting paid millions? LOL.
Since India conceived the 'cranked' delta, you mean US copied it? Wow.
You still don't get it do you? It's a group of people working together that makes it happen.
This not a one man show.
There was a Chinese in the B2 program, he was super duper and made it all happen! This is the reason why India cannot achieve things. No cohesion and team work. All want to be the boss and talk alot while taking all credit.. Boasting conceals a deep inferiority complex.
as i have mentioned this is used in the space shuttle and f-16xl. this design allows for a delta design to achieve a higher aoa and greater lift as if it had a canards but still not the same because it will never and therefor it can not achieve the higher angle of attacks true canards provide but comes close with its own advantages in other areas.
this design allows for a greater wing area, thereby increasing lift and reducing wing loading. the lca is marketed as the lightest combat aircraft in the world.
I don't care how a delta wing compares to a 'cranked' delta. My question was why pure delta wings were replaced by delta canard configuration as seen in all major aircraft makers. Su-20MKI added a canard. And how do you define cranked? How cranky you need to get to be called cranked? The shuttle had crank in a different location with a different degree and so did the F-16XL.
Does being termed 'cranked' like the F-16XL make the LCA comparable in performance?
its about effiecency, in short summary if you understand all this.
j-10 wing loading 335 kg/m^2
mig -29 = 442
gripen 283
typhoon 312
tejas=221
Nobody knows the performance of the J-10, its state secret. It is either super or suck. LCA is not even operational.
now the tejas has the lowest wing loading because it is small and has very large wing area relative to its size which is a plus and helps with lift, payload and most importantly takeoff and landing fuel consumpation.
it does not mean the tejas is the most agile in the air, that was not the goal, the goal was to make the aircraft atleast close in agility.
when the project was initiated, india already had access to bvr capable mirages and falcrums.
In that case, we shall use the L-15 against LCA. So you are trying to say Mig-29 has a high wing loading but then less wing loading does not mean LCA is more agile but because you are small hence you have less wing loading? Pretty obvious isn't it.
Close in agility to what? My toy plane? Want to try go against Mig-29 with your agile light plane?
was speculated that bvr would kill the dogfighter.
that to some extent is true.
but the real killer to high g turns was the arrival of helmet mounted sights with targeting. the tejas uses HMDS. its good enough.
Alot of plane uses HMDS. The point is do you MAKE THEM!!!
there is a mantiance advantage to avoiding the canard or extra control surfraces as well, there would be less stress on the air frame etc... and less moving parts.
the other advantage is the reduced weight.
you might want to know that despite the nearly same capability the gripen a provides, its empty wieght is greater. the gripen has yet to recieve an onboard oxygen generator. the tejas already has these small bells and whistles.
its not to say the tejas is manuavrable or the best dog fighter. it stands out in other areas as well.
RCS is reduced on the aircraft and one of the reasons being the lack of extra control surfaces.
If you want an arguement you may as well use the one i have enjoyed and is the least refutable.
because of the size of this aircraft, it has limited growth oppurtunities.
meaning, more will be added to the outside rather than in.
the gripen suffers from the same short fall.
For ease of maintenance, I suggest you use propeller planes. Don't use jet engines, less moving parts, less complexity. Jet planes moves faster, more stress my man. Propeller planes are slow and steady. Why not but a propeller plane light trainer, those Cessnas seems like a good idea man. Hook up some missiles with a wire, no complex FBW. Just release the wire to drop the missile.
Gripen no oxy gen? Then what is this?

200 Gripens were made, LCA? What are you guys smoking? Please don't live in Bollywood land. Don't be like the boy that says he is proud to be a slum dog. "I am starving so what....at least I am proud and happy". I am shitting in the streets, so what? I am proud of it. LCA sucks so what, I am proud of it.
Aww, now you compare to Gripen. How much is the RCS reduced? It's small so less RCS? You mean the radar can't see you with those 'cranked' delta wings?
My toy plane has low RCS too.
You avoid canards because you have no experience in it and is unable to create a stable control system. Why not put it in another way, cars are fast but it's less stable, so lets cycle.
Who told you LCA is as good as Gripen? My friend, you claim all these but then Gripen is operational and is not a rejected half baked foreign designed and made plane. Until now, nobody can give me a definitive answer whether this plane is indigenous. You tell tall tales, how LCA is supposedly lighter, agile, less weight, less RCS. If the solution was so simple, why not make a trainer the next fighter? L-15 is a good choice right?
My friend, one last crucial question. If the LCA is as super as you claim, how come your own air marshall is calling it a MiG-21+ plane?? Why is it always in testing mode??? Hell, it is comparable to Gripen as you said. You want to knw what I think happened.
India paid the french for a 'cranked' Mirage design, review it and stamped APPROVED. The design contribution is the super duper intense technical talent spent to look at the drawing.Hence, this plane is designed by India. Then they paid a host of other consultants to get the composites, control systems and avionics. Assemble it and called it system integration. Walla you have a plane. But due to crappy design, the air force will not accept it and hence in perpetual testing mode. LOL
