    let me qualify it further..all new prototypes with new landing gear configurations do not retract their undercarriage. Once it has been validated, other prototypes retract theirs during their first flights..for instance, LSP-7 retracted its gear during its first flight itself, since they were confident that it would work fine and had no risk. But TD-1 didn't retract its landing gear during its first flight being the first of its type. NP-1 will follow the same principle.
    Yeah, I agree.
    But before any flight tests, tests on under carriage are done numerous times when the airframe is still on the assembly line. But still its a norm for almost all to keep the undercarriage non-retracted during their first flight.

    But what i was mentioning was w.r.t to the article in which the author mentions non-retracting as a sign that something was/is wrong.

      At worst, an Indian deal to buy modernised An-124s off a re-opened production line could have been another Gorshkov, with years of delays & demands for more money to complete the deal.

      India was able to buy C-17 from a functioning production line, with both delivery & performance assured.
      Gorshkov and An-124 are not the same, work on Gorshkov was much more complex and was like building almost 2 carriers.
      The dealy in An-124 procurement will be on how soon they can start production of the aircraft and deliver it. But the cost of An-124 will anyway be lower than that of C-17 for the same number of orders. $400+ million per aircraft for strategic heavy lift is just insane!
      IAF still don't show any urgency for augmenting the the AWACS fleet, but they are more interested in having C-17s and strategic airlift.

      I don't believe India is in the market for a strategic heavy lifter.
      True its in the class of C5 and still the An-124 costs less than the C-17.



      Btw, C-17 is bought as a strategic heavy lifter by completely ignoring the true heavy lifter on the market.
      Like the Bofors, in the near or distant future we'll get to hear a lot on who all made money in many deals that happened from 2004 onwards...

          Never been in an An-32, but have jumped from an AN-26. Very loud, then again I wasn't expecting a Toyota Prius.

                    Wings aside, the fuselage look a lot like the Hawk

                      If the levcons were any larger, I would have been inclined to call it a flying wing. That fuselage looks tiny compared to the ridiculously large wing area.

                          Its always been Lca Navy or NLCA or Naval LCA , Navy might have a different name for it

                            Good to see NLCA finally fly.

                            Is there any shots of its landing? and how long did it run to halt?

                              Good job team HAL, good job. One very handsome bird that's for sure. So what are the next Tejas prototypes /series slated to fly and when? Thanks.

                                they did not take the route of MiG-29K/M in having an underbelly point for the drag chute and arrestor hook.

                                  The Design of first indigenous Naval aircraft imposed huge technological challenges to the Defence Research & Development Organisation (DRDO) to meet the peculiar requirements of Naval aircraft; starting from saline and humid environment of operation, restricted availability of deck run for launch and recovery and high operating load conditions. Basic design changes required to suit the carrier operations are strengthening of aircraft structure and Landing Gear, Arrester Hook, improved engine, enhanced aerodynamic performance and incorporation of special metal/material. A host of other systems like the Leading Edge Vortex Control (LEVCON) surface fitted at the front end of the aircraft wing operated by a concealed rotary actuator with aerodynamic profiling to ensure low landing speed, good controllability and better vision for the pilot. The feature of launch and recovery onboard Carrier at high sink rate of 7.1 rn/sec, flareless landing with engine to full throttle till arrested by deck cable impose five times of loading on Main Landing Gear as compared to the IAF version. Also such axial load calls for re-certification of all Line Replacement Units (LRUs), components and associated systems of naval version to ensure fail safe operation repeatedly.

                                  Any idea on when they intend to have the definite variant of a carrier based aircraft with arrester hook?

                                    Without a doubt ! Now, add a 0.5 meter (some say 1 meter) plug aft of the cockpit and remove the second seat to make it a single seat NP-2.. My guess is that definitive NP-2 (based on the Tejas Mk2 and NP-1) will be the best looking LCA variant with a better aspect ratio than the Mk1 derivatives that are there today.

                                        I don't see any arrestor hook yet, but NP1 and NP2 are supposed to demonstrate carrier landing capabilities by early 2013.

                                          Just wondering, having missed all deadlines in 2011, are they in a position to deliver first serial production units this year?
