Re: LCA News and Discussions
Soon expect a DMM writen article saying "Since LCA can not carry at least six Agni 5 (which itself is a outdated missle) under each of its wings it is a waste fighter. India should purcase F16 which will carry 12 Minutemen under each of its wing which can be used againt Maldeivs"

Re: LCA News and Discussions
Any news on NLCA? Been quite some time since its anticipated first flight
Re: LCA News and Discussions
nope.. AMCA thread is appropriate. LCA has many enablers, but the program itself is not chartered to be compared with these two.prabhug wrote:There is an article here

Can we analyze how relevant is LCA is with these points.

Very good news if trueWhile some crucial parts of NP-1 gave nightmares to both designers and engineers, including the bulky undercarriage, sources now confirm that the defects have been rectified.
The NP-1 will be put through another HSTT next week before the Aeronautical Development Agency (ADA) and HAL combine take a final call on the first flight. “Everything is in place and our engineers and technicians are leaving no stone unturned ahead of the first flight. We had some software snags which have been rectified at the right time,” HAL sources said.

clearance means, the undercarriage issue sorted out, what to watch would be the moveable levcon in action. AOA!

Re: LCA News and Discussions
Naval Tejas , successfully completed last high speed taxi trials yesterday and NP-1 has been cleared for its first flight . as per sources today will be the day the first flight likely to be carried out .
after issues with undercarriage and Landing gears , problems seems to be sorted out by ADA and HAL and it was certified airworthy recently , it was twice in recent times flight worthy certification was denied to it .
Re: LCA News and Discussions
strange that tarmac not reporting anything about the NP1 flight even though being based in Bangalore

Re: LCA News and Discussions
Ah..this explains why HT on its news channel was mentioning the nlca flight planned for today in the morning and took off that ticker later in the day.

Re: LCA News and Discussions
Friday at 10 am!
LCA naval variant’s first flight on Friday
LCA naval variant’s first flight on Friday
After almost two years since its rollout, the naval prototype (NP-1) of the country’s Light Combat Aircraft (LCA) will take to the skies on its maiden flight this Friday.
The flight is slated for 10 am. But it will fly with some unresolved problems. The maiden flight, however, does not mean the team LCA has overcome all the technical glitches that had forced it to miss several deadlines in the past.
The Centre for Military Airworthiness & Certification (CEMILAC), sometime last week, gave its clearance for High Speed Taxi Trial (HSTT) and flight.
The flight will last 20 minutes with the National Flight Test Center (NFTC) pilots doing a sortie over a designated flight path besides testing the systems onboard for performance.
But they will not retract the undercarriage, as they do not want to take a chance. “It is potentially risky to retract it,” a source said, indicating that there are some problems still persistent. Isn't that the SOP for all first flights?The undercarriage is retracted to reduce the drag experienced by aircraft.
Compared to Tejas, the IAF version of LCA, the LCA NP-1 will be different with a longer and stronger gear, front fuselage droop for better over-the-nose vision, an additional control surface to reduce carrier landing speed and consequential changes in various systems and will fly with a GE-F404-IN20 engine.
Designed specifically for ski jump take-off and arrested landing, the aircraft was faced with heavy undercarriage problem, which sources fear might not have been addressed completely. The undercarriage was bulkier by 500 kg.
The aircraft is likely to replace Indian Navy’s Sea Harrier squadron, and already orders for six aircraft have been placed. While the NP-1 is a twin-seater trainer, the NP-2 will be a single-seat fighter.
Re: LCA News and Discussions
On the contrary, not wanting to retract it is simply a routine risk reduction exercise. The F-22 story:“It is potentially risky to retract it,” a source said, indicating that there are some problems still persistent
Advanced Tactical Fighter to F-22 Raptor: Origins of the 21st Century Air Dominance Fighter
Landing gear retraction was not attempted on the first flight but did not work when it was attempted on subsequent flights. <snip> A successful gear retraction was accomplished on the fifth flight.
Re: LCA News and Discussions
So, on the testing.. is it not possible do rectraction testing while the fighter is in the state of flying (fixed to some hangar support and bolted down, raised up).. perhaps the engine is throttled for 200kmph creating near real simulations.
?

Re: LCA News and Discussions
They would have already done that - simulations in the research & design phase and then during & after development on a static test jig and on the LCA platform. But this is not the same as testing on an actual platform flying at xx knots for the first time. There are a host of other factors that will come into play. Besides for the first flight, more important is that the NLCA flies (aerodynamics w/ FBW etc) and if risks can be mitigated by not retracting the landing gears then that should be done.SaiK wrote:So, on the testing.. is it not possible do rectraction testing while the fighter is in the state of flying (fixed to some hangar support and bolted down, raised up).. perhaps the engine is throttled for 200kmph creating near real simulations.

Re: LCA News and Discussions
Indeed, the testing of the retraction of the landing gear is done on the Iron Bird rig. At the 2:09 mark in this video, you'll see the retracting landing gear on the Iron Bird. This would've been tested for the naval prototype's landing gear as well. Apart from that you can go to the 9:22 mark in this video to see it being done on a real Tejas prototype.srai wrote:They would have already done that - simulations in the research & design phase and then during & after development on a static test jig and on the LCA platform.

All this is done apart from the specific landing gear tests (such as drop tests shown at 9:27 in the latter video).
Re: LCA News and Discussions
I'm being pedantic, but its not really contrary is it? It's the same thing. Risk reduction implies reducing the chances of occurrence of something that is risky.PratikDas wrote:On the contrary, not wanting to retract it is simply a routine risk reduction exercise.“It is potentially risky to retract it,” a source said, indicating that there are some problems still persistent
Re: LCA News and Discussions
But there aren't any persisting problems, in all probability

is there any update ?
Re: LCA News and Discussions
Just heard a fighter type take off- could not see through the clouds.
Edit: I "think" she took off a minute ago- the first one might have been the chase bird.
