well, this is the first time that i agreed with sens -maybe the last 😀 -, 😮 😮 😮 the lavi, EF, j10, mig1.42,rafale,grippen etc, are standar solutions for the ustable concept, the j10 isnt a copy of the EF or an lavi with diferent intake :confused: :confused: nahhh , pssss….

we must acept that china developed itself the plane, maybe there are some ideas from the EF -maybe-, but that doesnt mean that is an ef copy and definitively not from lavi, but out of the airframe there are sistems more important (like fbw or radar), in wich the occidental concepts -only concepts-could have some influence.

erez your talking like an frustrated nationalist, your saying the same of “without USA cannot design the lavi” american propaganda argument to the chineses an j10, the lavi was tech successful, but not comercial industrial success (production costs, and lack of market -Latin America,Africa-).

yes, everybody knows that, but that dont mean that are supersonic planes, the f18 and f14 can reach very low supersonic speeds without afterburner, but it dont mean that are supercruiser planes, maybe the 17 was the last and more advanced 1st generation plane (like the EF)

could we start an rockwell vs McDD concept???:p ?

well there were not prototipes of the fx loser concepts??? after that competition start the concept of real prototipes tested by usaf pilots (f16,18,22,23)?? why??, maybe because the usaf didnt like the result, or by corporative reclamations???

the rockwell plane had a name (or code) what mean NAA?? the lerx extensions are vortex generators?? (i have that doub because the leading edge ratio is too big to induce an significative efect)

thanks for your patience :p

thanks aerospace.

the unique engine aviable for the f15 proyect was the f100, were not an competition of that engine (maybe an version of the tf30 or anything else)??, its funny, the rockwell-north american concept looks like an su27 in an special way.

obvius, thats why the classification only is about airframe-aerodynamics, but also those concepts give you an very good reference

all you guys are wrong, the classification depends on which tech is aplicated (engines, aerodynamics, electronics etc….), in the aerodynamics-airframe field this is the clasification;

generation classification

1st generation; primitive transonic aerodynamics (an tube with v wings)

2th generation; primitive supersonic, the rise of delta wing (mig21,mirage3,mig19 etc)

3th generation;bigger aircraft (to increase fuel and supersonic range), trying in the last planes to solve low speed problems with other techs-sometimes with VG- (f4, f5-small attack-,f14,mig23,f15,mig25,tornado, etc..)

4th generation; the rise of supermaneuverability- big name ehh -,lift bodies,lift vortex, unstable design, controls integration, etc (f16,18,mig29,su27,rafale,EF,etc..)

5th generation…..supercruiser, supersonic maneuverability, stealth radio-aero dynamics, etc….

now there are generation and generation+ like mig19 is an 2th generation plane and mig21 or mirage 3 is an 2th+ generation, etc…..

thats all…

the russians never will finish that sub, the pump is based in arquimades helix???, that is the standar pump design(for the trafalgar-seawolf)???
