ADA Tejas (LCA) News and Discussions

[Kaalapani]

I have a Question.. may be stupid ... The Drogue Chute that is deployed is it reusable? If no Is it necessary to use it every time when the plane lands?

it is used mainly to save aircraft breaks.

 

[Sea Eagle]

Just how many rounds of the main gun will Tejas carry ?

Also which LGB's can Tejas carry ?
I know about the Israeli LGB kit but do we have any compatible Russian LGB's for Tejas and can Tejas carry Sudarshan LGB ?

it is used mainly to save aircraft breaks.

But is it reusable or one shot use and throw and then replace it with a new one

RE usable.

Is there any Video on how they are spooled back in after the planes land...?

Really excited .... Thanks for the update....:cool2:
So, we can hope that other remaining LCA will be also rolled out this year only any update on that?

From previous sources we know that three aircraft will roll out ..

So, we can hope that other remaining LCA will be also rolled out this year only any update on that?

I says "NAVY" on the tail so I'd venture a guess that it was

MAJOR ACHIEVEMENTS

Tejas has successfully completed more than 2,590 flights and has participated in Hot Weather, Cold Weather, Iron Fist and Weapon Trials comprising of Bomb releases both in Computer Calculated Release Point (CCRP - Uses GPS for target acquisition and termination) and Continuous Computed Impact Point (CCIP - Uses Radar for target termination) modes.
R73E missile launching in MMR and Helmet Mounted Display Guided Modes successfully completed.
Stick Bombing, separation trials of emergency Jettison of multiple stores and Drop tank were conducted at various locations across India.
Other notable milestones achieved are Spool Down Engine relight, Envelope expansion up to 24 degrees Angle of Attack, operational readiness platform scramble, Laser guided missions with Litening POD, Fuel System, Brake Management System and General Systems performance.

Multi-role capability demonstration by simultaneous release of Laser Guided Bombs, Chaff&Flare dispensation and firing of R73E missile within a span of 100 secs. Other important achievements are night flying and wake penetration.
Advanced Composites development of engine parts, Bypass Duct, Nozzle Flap, Bullet Nose Cone, curing achieved in both-
autoclave and press processes, indigenous resin development, developed glass transition temperature in excess of 300ºc.

Indigenous aircraft paint system, characterization to DEF STAN 80-216, BS 2x 33&34 and application process fine tuned to Tejas.
Indigenously developed single trolley multiple operations, shorter flight readiness cycle time, loading trolleys for Drop Tanks, Weapons, Digital Flight Control Computer, Battery, Jet Fuel Starter, Landing Gears etc.
Realization of Product Life Cycle Management (PLM) - Implementation for all projects, complete product data management across work centers, pipelines and electrical looms data management, synchronization of data, query workflows from design through manufacturing, digital manufacturing and ERP interface, online design query management for faster disposition, real time status dash boards for effective tracking.
Production Optimization Introduction of laser tracker, high speed machining, automated drilling and riveting technologies, application of Design for Manufacture and Assembly (DFMA) concepts, production standard drawings, build quality improvement and product cycle time reduction.
Strength Test of Leading Edge Vortex Controller (LEVCON) for LCA Navy, successful flight trials with indigenously designed and qualified composite drop tanks, flight flutter tests for operational clean and heavy stores flight envelope expansion.

Water Tightness Tests, Lightning Test Facility and configured and commissioned Automatic Cable Harness Tester.
Production standard Digital Mock up (DMu) including system pipelines and electrical looms, capabilities like Geometric Dimensioning and Tolerancing (GD&T), analysis and assembly sequencing introduced.
Qualification of indigenous autoclave consumables like pressure sensitive tapes, vacuum bag sealants and release films for Carbon/Epoxy system.

INTRODUCTION

Tejas incorporates a highly reliable quadruplex digital Fly-By-Wire (FBW) Flight Control System to ease handling by the pilot. The digital FBW system of the Tejas employs a-
powerful digital flight control computer (DFCC) comprising four computing channels, each with its own independent power supply and all housed in a single-
Line Replaceable Units (LRU). The new-generation glass cockpit comprises Multi Function Displays (MFD), Head Up Display (HUD) and Stand by Instrumentation System driven by Open Architecture Mission and Display Computer.The computer interfaces with pilot display systems like the MFD is through the MIL-STD-1553B multiplex avionics data buses and RS-422 serial links. MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus.
Tejas is intentionally made longitudinally unstable to enhance maneuverability. The Control Laws (CLAW) recover stability and provide good handling qualities to the Pilot.

The Tejas is a pilot's aircraft and nowhere is this more evident than in its handling qualities and performance characteristics. The fighter rockets off the runway and into the air in a mere 500 meters, and the-
control harmony and carefree handling characteristics are clearly demonstrated in the almost poetic ballet in the air that is the aerobatic display routine. Tejas development
program has also accomplished the design and development of two-seater trainer aircraft for Indian Air Force (PV-5). Being a fully operational trainer this prototype is also obtaining the full operational clearance.

Avionics and Weapon Systems:
Advanced Glass Cockpit with High Performance Graphics to Support Situational Awareness, Decision Support and Data Fusion.
Dual Redundant Open Architecture Mission and Display Computer.

Two microprocessor based Electronic Units monitor and control the on-board General Systems such as Engine, Electrical, Hydraulic, Fuel and Environmental Control Systems. Helmet Mounted Sight, Multi Mode Radar, Litening Pod and Radar Warning Receiver
Digital Weapon Management System Compatible to Russian, Western and MIL-1760C Weapons.
Single Avionics Application Cater to Multiple Variants of Aircraft. Proven Air-to-Air, Air-to-Ground Attack Modes.

Propulsion
Successful Integration and Flight Testing of GE-F404-F2J3 and IN20 Engines.
Enhancement of Jet Fuel Starter with GTSu-110 M1 for LCA Mk1, and Development of high power GTSu-127 for LCA Mk2.
The On-board Engine Condition Monitoring System provides real time Engine Status in the Cockpit and Logs the Engine usage Data to Compute Life usage Indices of Parts. It also equipped with a Vibration Monitoring System.
Enhancement of Engine Ground Test Facility to test IN20 engine. Alternate engine program for LCA Mk2.

General Systems:
Single input, multi output gear box Aircraft Mounted Accessories Gear Box (AMAGB), Carbon-Carbon Composites for Aircraft Brakes.

AFAIK they are not simply spooled back in- they are released once the fighter is down to a certain speed and then it is for ground crews to collect the shoot and repack it into the fighter.

oh ..What Happens when there are multiple sorties of the same aircraft and/or multiple aircrafts operating in close succession

Number of drag chutes availlable will be more that no of planes.may be 1:10 ratio bhai.Use kar.
