From Tejas - LCA Facebook page

Saurav Chordia is a young Boy from Basugaon in Assam. Only 19 years old, he currently studies in Delhi, his dream is to become a Defence Analyst. Besides studies he is an Aviation Enthusiast and is up to date with the Current Aviation Affairs in India.

This inspired him to try his hand in Aviation Art and design different types of aircrafts when he was in the 7th Standard in School. It took him more than a year to Master 3D Software to render High Quality Images. He learnt everything on his own and last year the Makers of the Indian Air Force Game ‘Guardians of the Galaxy’ discovered his Talent and invited him to do a 3 Month Internship with them.

He also designs art for Retired Veterans. He does war reenactments like Dogfights, Bombing Ground Targets and much more. He has designed these for the likes of Marshal Arjan Singh (Spitfire), Retd Naval Chief Arun Prakash (Sea Harrier), Retd. Chief of Air Staff N.C Suri (Hurricane), Flt. Lt. Alfred Cooke VRC 1965 war (Hunter Shooting Down Sabres)

Before starting any work, he collects references with proper dimensions. He uses multiple tools like Blender for designing, Cinema 4D for Rendering and for tweaking and filtering Adobe Photoshop.

Little about Basugaon. Its in Kokrajhar district. As per some of our eastern and western neighbours, it is a place for anti India movement. Now work of people like Saurav should be a slap on face of these so called experts.

Parts made by 3D printing won't help.....?

Now-a-days metal alloys in powder form are used in 3d printing. Cobalt, Titanium and Aluminium..all are candidate materials. However, these materials in 3d printable form are proprietary and very expensive. Moreover, mass being same, I dont think, they will be any lighter.

Watch it @ 1:11 please.................................

Good find.

I think the reason why it is lighter is because what used to be many parts, is now a single part. If you have multiple parts bolted or welded together, that will obviously increase the weight.

Now, if we have a single piece part made by the traditional method and then by 3D printing, both will weigh the same. Specific gravity of a metal will be same in either case.

At the end of the day, we wants light weight parts.
And if it works in that way, then what is wrong in it.

I am not saying anything is wrong with it. I am just trying to reason out why the 3D printed part is lighter.

They can try this for other products too.
Might help.

Anyone having any updates on ELM-2052 AESA radar integration on Tejas ? Has the work started? Any timelines for testing?

 

[Kunal Biswas]

I have posted a link in few last pages regarding the matter, Its integrated and in testing ..

Being a short range fighter, Tejas should have been based in one of the frontline bases after induction.
I guess, Sulur will probably host something similar to MOFTU as was in Tezpur for Lead-in fighter trainer program.
Maybe mk-1A onwards it will be based on the frontlines. Anybody know about this?

This has been based at Sulur right now due to its proximity to HAL. Idea is to provide first hand on site training to IAF maintenance crew and to sort out any issue with the production batch. It would shifted to frontline by next year onwards hopefully.

We need to work on increasing the speed of Tehas to atleast 1.8 mach and Horizantal turn rate should be increased to 20 Second a loop and weight carrying must be increased to 4 ton and range by another 300 KM atleast and 2200 KM preferably. If this done than Tejas is a winner.

Mate, Tejas is an LCA. What features regarding payload and range you mentioned is for MCA.

In other words, you actually admit that without all these LCA Tejas is not a winner .......?......!

Sulur is not far from Bengaluru.

May be that is why they prefer it for initial time being.

Sir, can this be shared again.. not finding it. Sorry to bother u again.

Yes, Tejas is not winner at this stage but Tejas Mk1+ shall definately be a winner. 500 KG weight shall be slashed resulting in 8% higher T/W rati. 8% aerodynamic improvements shall come. Trans sonic acceleration shall improve by 20% and top sea level speed by 2%. There shall be an additional weight of 60 KG reslting into 3% higher range. Aerodynamic improment shall increase range further. There will be a win win in any improvement in tejas from now onward. Vivek Ahuja also says this in his simulation studies of Tejs MK1. You know it better since you had posted those beautiful piece of study on PDF.

Fair enough.

But keep in mind, if they do all of these as you asked for.
After it, still people won't stop, that it is not enough and needs more.

LCA Tejas Real Time Simulator (RTS) Ready For Pilot Training

LCA Tejas Real Time Simulator (RTS) has been upgraded to a full mission simulator. The formal assessment of upgraded RTS was carried out by National Flight Test Centre (NFTC) test-pilots in coordination with IAF-Programme Management Team (IAF-PMT), ADA-Integrated Flight Control Systems, and Centre for Military Airworthiness and Certification (CEMILAC). Fully configured upgraded RTS is ready for training and will be offered to IAF-PMT to provide training to the squadron pilots.

A formal event to declare the readiness was held on 18 April 2016 at ADE, Bengaluru. Dr K Tamilmani, DS and DG (Aero), was the Chief Guest of the function. Director NAL, Director ADA, GM (LCA), HAL and other dignitaries from ADA, IAF-PMT, etc., participated in the event, along with ADE fraternity. Shri MVKV Prasad, Director, ADE, welcomed the august gathering and highlighted the importance of simulators as a training device.

Shri BP Shashidhara, Group Director, presented the evolution of flight simulators at ADE, starting from the development of Kiran simulator during 1980s to LCA mission simulator. He highlighted the challenges faced, especially during US sanctions, various technology components used, meeting the user requirements, lessons learnt, expertise acquired, etc. He also acknowledged the immense support extended by various stakeholders towards the development of the Full Mission Simulator.

Dr K Tamilmani, DG (Aero), DRDO, handed over the relevant documents to Director ADE and Air Marshal Rajesh Kumar, VM, Director IAF-PMT, and declared the readiness of LCA Tejas RTS for formal training of IAF pilots. During his address, DG (Aero) appreciated the efforts put in by the team ADE to upgrade the RTS and highlighted the need for development of more full mission simulators for other operating units.

He emphasized the need for evolving a formal mechanism for version control in line with aircraft modifications and also to retain the talent in the country and create a knowledge base. He wished ADE to continue to be the Centre of Excellence for Flight Simulation. Air marshal Rajesh Kumar in his address highlighted the challenges ahead in terms of Radars, EW suites and other latest weapon configurations for LCA and appealed to meet these challenges within the timeliness for full mission simulator at Sulur.

He also added that the RTS available at ADE would meet the initial training needs of IAF squadron pilots. This simulator would be extensively used for training of IAF pilots on basic missions of LCA-AF Mk-I. The existing nine meter diameter dome-based facility at ADE is being upgraded to Full Mission Simulator to meet the ab initio training requirements of the IAF pilots under both normal and emergency flying conditions. The RTS cockpit has been replaced by a cockpit closer to production standard aircraft of LCA.

Real pilot controls have been used and all the synthetic displays and the cockpit panels have been replaced by actual systems to the extent of their availability. The avionics systems are a combination of real LRUs and simulated LRUs. The visual cueing systems used in the RTS are retained. Aural cues are based on actual digital recording of the LCA sound as perceived in the cockpit for various throttle settings and is rendered in real time during the simulator sorties. A 5-DoF G-seat/suit combination is integrated with the Martin Baker Seat of LCA (MK IN 16G) to simulate various acceleration (limited motion) cues.

The simulation of avionics systems in the upgrade is being carried out in phases. In the first phase, the avionics systems required for basic mission training has been simulated. An Instructor Operator Station for remote operation, control and monitor is also part of the training simulator set up. Instructor has the facility to take over in case of emergencies. A timestamped history of the entire flight sortie is also incorporated for effective debriefing post flight.

ofcourse. Me must devise a plan like what America did for F18. A continual development.
