    The lesser swept wing leading edge angle is 50 deg for tejas, In F-16 Xl also the leading edge wing sweep angle was 50 deg as per the following link. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.51.2771&rep=rep1&type=pdf Approach to High Angle of Attack Testing of Light Combat...

    One above is F-16 Xl, the one below is tejas tejas wing has much lower sweep back than F-16 Xl, which outscored the much higher wing loading normal f-16 on all counts.And had no canards and tail planes as well , and had very low wing loading as well. now "Wing sweep Angle " experts who defy...

    v is speed and that v is very much dependent on wing loading which determines the horizontal component of lift vector. if the horizontal component of lift vector is higher automatically v in increases in sustained turns because Newton's second law can not go wrong in speeds below the speed of...

    Newton's second law which gives the following equation L sin(θ)=mv*2/R A low wing loading air craft will always bring higher horizontal lift component into sustained turn turn for any given bank angle θ at a lower AOA (which means with lesser drag)and speeds much hihger than stall speeds...

    Why do we need max bank angle. the key as per Newtons second law is for any given bank angle, First you understand Newton's second law which gives the following equation L sin(θ)=mv*2/R A low wing loading air craft will always bring higher horizontal lift component into sustained turn turn...

    Refer to the Newtons second law part in my past answer and you will find it. Clarify your position on the following passage first, Rate of turn and Radius of Turn. Rate of turn T (*/sec)= 1091*tanbank/v Radius of turn R (ft)=v^2/ 11.26 tanbank And for claims like ,that rate of turn and radius...

    Smaller wings doesn't necessarily reduce drag in proportion. The calculations I posted from Myth busting forum, conclusively prove that. Meanwhile a smaller wing would have reduced the win lift and reduced the STR and ITR drastically, since no point in ," fancy high wing loading non -RSS...

    Mig-29 has double the engine thrust of tejas and has a very low fuel fraction , which was built out an out as an interceptor, while fighters like mirage-2000 and tejas are built RSS , low wing loading multi role fighters that can dominate the himalayan heights.

    You first show equations and source to substantiate your point --"THE Lift is dependent on CL+Density+Speed+wing area. Any aircraft can play around with these components of the lift to maximize the lift to get the required bank angle to have high turn rate and low radius. ", of course with high...

    As per Rate of turn and Radius of Turn equations,XXX degree bank at ZZ speed would produce the same turn rate regardless of the aircraft weight or wing loading .. Rate of turn and Radius of Turn which I reproduce here also. Rate of turn T (*/sec)= 1091*tan(bank angle)/v Radius of turn R...

    Warren .F. Philip again says that designer has no control over max lift co efficient (which is between 1.2 and 1.6)and air density. So the primary feature the designer must use to control the lift performanace is "wing loading". Three times with in a span of three pages. Cl=2L/Psv^2. In the...

    nothing wrong with it, I also know that ,"total lift is a combination of wing lift + fuselage lift+ Lift component of thrust". but wing lift makes the substantial portion of total lift. I told you that "the other parameters being the same " is a lay quote by a poster on the forum, which I...

    Do the Migs , Su-30s , F-16s , F-15 s, gripens, rafales, typhoons and Gripens have flat rated engines? Su-30 MKI in those exercises had thrust vectoring engine. None of the US fighters had it. f-22 has a combo of thrust vectoring engine and high TWR so it has best ITR and STR. you are at...

    "Lift is dependent on many factors which I enumerated in my posts" What are these factor? But first you try to understand the Newtons's Second law of motion. Then you will know why lift is the deciding factor in Sustained turn rates and low wing loading design is the best way to get a higer...

    Then how can you explain the difference between wing loading of PAKFA and SU-30 and the difference between wing loading of F-16 and F-22? their aircrafts have thrust vectoring and superior thrust to weight ratio, which is going to be solved in tejas mk2 which will have better TWR if not...
