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.

@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...

Guys a new video on LCA Tejas carrying some old footage though. http://www.youtube.com/watch?v=dnYeReCbDBA

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 ...

@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...

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...

Team Tejas Performing Tests in Full-Form.Yeepee!

I didnot know my contacts with many profs. Would allow me to go the HAL ,Nashik Plant. Wow! In Dec this year.BTW whats the news on AOA of Tejas?

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.

Is there any news on Which softwares are being used for CFD analysis of Tejas in aspects like Forced Vortex,Wakes,AoA etc.

Well today after 2-3 months i have seen dhruv flying feels good rains have gone and helicopters have come back .We cannot really doubt the Dhruv ,it has got excellent sortie rate.

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

@rajkumar Although this is my Opinion his might be same as well-That manuf. Prac. Need to shift gears when transferring product from TD stage to SP stage.@Kartik The tapes you are talking about are for NC machines while it is time to shift to faster CNC component manu. unit and assembling.Warm Regar...

I have recently read about these guys starting procedure of Investment Casting (Vaccum Based) for manufacturing Blades looks bad even France started that during 1990's but these guys have started atleast .

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.
