Good now they understand, No talk only work.. :)

Np 1 took another flight. Good one.
wtf=what the f uck

Some write up from Net about Wake penetration.


The effects on the structural design of military and civil aircraft caused by dynamic loads resulting from the flight through high wake velocities which are generated by different types of aircraft have not been sufficiently investigated in the past. Military aircraft might experience this impact during formation or squadron flight or during combat manoeuvres. Civil aircraft could be affected during start and cruise through wakes from other aircraft.

Passing through the wake the safety of the aircraft might be critical by wrong guidance, uncontrolled movements or by induced dynamic loads which might cause failure of structure or structural fatigue.

The design of aircraft structure accounting for wakes is not state of the art. The standard design includes dynamic loads from PSD gust analysis and buffet or tuned gust analysis, where the intensities of the gust velocities are defined by military or civil specifications and buffet intensities are defined from wind tunnel test results (Ref. 1).

Predictions by analysis of wake velocity fields of different aircraft indicate however that the known maximum gust velocities are exceeded and the time history of the velocities experienced by the affected aircraft during penetration is different for example to the 1-cos gust in the discrete analysis. Moreover flight test results of the dynamic aircraft response during wake penetration produced evidence for its criticality in several flight regimes.

This contribution concentrates on military aircraft and demonstrates several examples of predicted critical wake fields and results from calculated dynamic response during different kind of penetration. Also examples from flight dynamic responses are discussed.

Finally some recommendations for future research and activities are given which should lead to a wake and wake penetration specification for military and civil aircraft required for future structural design and clearance.

In which aircraft was the EW suite being integrated? I thought some PV series. It it was PV3, then this is good news.
 
. .
Any news of LSP6?

Any video of LSP8? LSP8 seems to have a lots of redesigns. Air intakes are Huge. It must have given LSP8 a batter performance.

There was a news that some design change resulted in some performance improvement. Anybody has any idea?

I do not think there are any visible differences, Can any one find any?

LSP-5 is painted in grey while LSP-8 in yellow :smart:

The Air Intakes appears bigger in the yellow one. could be due to the paint difference.

"The production work has already started at full throttle. Currently there are no bottlenecks to prevent rolling out of the first lot of these indigenously built LCAs by middle of next year," Chander told TOI. "The production rate, I believe, is around 16-20 per year and huge orders would assist in good production rates," he said.


Although the time frame for getting the initial operational clearance-2 for Tejas has been set as 2013 end, Chander said he was confident that the aircraft will be ready for the clearance by end of September. "Final Operational Clearance (FOC) for our first modern light combat aircraft would follow soon thereafter. Meanwhile, these two processes can go on parallel tracks to save time in delivery and induction once the IOC-2 and FOC are given," said the DRDO chief. For obtaining IOC-2, clearance has to be given at three different levels, including one from the defence minister and another from the chief of air staff.

Engines manufactured by US-based General Electric Aviation would be powering these indigenously manufactured LCAs after the global giant won the contract in 2010. After the initial supply of 99 engines (GE F-404 and GE F-414) for IAF and Indian Navy, the rest shall be manufactured by Hindustan Aeronautics Limited in India after obtaining a licence under a transfer of technology agreement. HAL will than manufacture 40 GE F-404 engines in two lots of 20 each for Tejas Mk-I and another 100 GE F-414 engines for Tejas Mk-II.

September is done. No news yet of IOC-2.
I see two things going wrong.
1) DRDO/ADA/HAL has obviously delayed the hell out of this project and is not complete yet.
2) IAF without taking what is available and improving it, is sitting for that perfect machine. When you have a donkey, use it till you get something else.

This is a 'september 1st' news. Why are you posting this now dude?? It can mislead people.

Old news dude. It wast news from TOI posted on 1st september.
