Re: LCA News and Discussions

Hello Bashers,Total force=(grav+pres+vis+tur+com),Reynolds eqn=(grav+pres+vis+tur),NS Eqn=(grav+pres+vis),not considering turbulent force during cfd will cause results to be inaccurate.Also cfd analyzer can b used to simulate full air shows without spending a drop of aviation fuel.Thanks.

Re: LCA News and Discussions

@SaiK A look at HAL Nashik labs told me one thing they have got a CFD Analyzer there that is a full blown software but it works on the basis of Navier-Stoke's Equatand not on basis of Reynold's Equation i.e. it avoids the compressible fluid force that is acting on the body.If status at this moment i...

Re: LCA News and Discussions

Everyone knew there will be delay in FOC but so as to find the reason for delay we need to find what does the FOC mean?Firing and final verification of A to A missile,dropping dumb bombs,LGB,AoA Figure of 21 ,night attack trials,all weather test,CMDS system testing,lightning protection system,RADAR ...

Re: LCA News and Discussions

@shubham The formula is not wrong surely because you can find it in the very popular RK BANSAL FLUID MECHANICS.@other members Tell me what could be the measures required to improve AoA (refinement in CFD Simulation model).But if this is the thing they are going to do then why?Because modern CFD Simu...

Re: LCA News and Discussions

Guys The txt bk defination for AoA is 'Acute angle between the chord line of airfoil and the direction of flow of wind' this is what i studied in Second year mech engg. And its significance is that Coeff of lift = 2 pie sin(AoA) .But i am unable to understand what is the AoA Problem of Tejas being r...

Re: LCA News and Discussions

My Point is dev. Of defense products goes this way-First ADA needs to develop Tejas completely (so that it can get high no. Of orders from IAF and not TOKEN inductions),by that time another firm(HAL) should not only manu. The TD but also establish produ. Lines for speedy induction.

@pratikdas Sorry for misunderstanding the Said term but CNC manufacturing is more related to metal parts Eg landing gear,control surface hinges,servos.

Re: LCA News and Discussions

Well i had myself had a chat with a HAL Engineer from Nashik Division And he was of the opinion that Tejas cannot really be mass manufactured under the present manufacturing practices and technology.And i hope this trend can be changed.
