Aircraft Research and Design Centre (ARDC), one of the Ten Research & Design Centres of Hindustan Aeronautics Limited (HAL) and a name well recognized in the international Aviation circles for over 50 years, is one of the pioneering organizations in India in the field of Design, Development, Prototype Building and Testing of fixed wing aircraft. An organization which began as the Engineering Department of the erstwhile Hindustan Aircraft Limited has over the past decades grown into a full-fledged R&D Centre driven by top technologists, powered by bright Engineers and ably supported by Commercial, Finance, HRD and allied groups.

ARDC has 13 successful aircraft Designs to its credit, ranging from basic piston Trainers to the frontline combat aircraft (HT-2, PUSPAK, KRISHAK, MARUT, KIRAN MK-1, BASANTH, AJEET, KIRAN MK-II, HPT-32, AJEET TRAINER, HTT-34, LCA and IJT). These workhorses of Indian Air Force (IAF) have blazed their indelible trail on the Indian skies over the past few decades. In addition to de novo designs, the Centre has also integrated new weapons & systems on existing military aircraft.

ARDC has a full spectrum of expertise in all facets of aircraft design & development. Acquired through sustained learning and R & D, our proven capabilities are backed by rich in-service experience spanning over five decades. The Centre has extensive state of the art test facilities and full fledged manufacturing infrastructure for building aircraft prototypes & test articles to support flight development programmes. It has advanced CAD/CAM/PDM facilities & fully integrated Network systems. The Centre has been certified for the Development of Military aircraft and has been recognized as an R&D Centre by the Department of Science and Technology. ARDC is committed to the pursuit of excellence through continuous improvement and innovation

ARDC has well-established and proven design office procedures and configuration control procedures. Design quality is ensured through analysis, review, testing and documentation. We also have proven quality assurance procedures in all the phases of manufacture of prototype aircraft that conform to the requirement of military airworthiness requirements.
ARDC undertakes:
  • Design & Development of basic and advanced trainers and combat aircraft from concept to certification
  • Integration of new weapons and systems on existing aircraft.
  • Testing of aircraft structures and systems covering preparation of test requirement, test plans, rig design, instrumentation and analysis.

Intermediate jet trainer (IJT) – HJT-36

IJT designed with superior performance and improved training effectiveness will replace the ageing fleet of Kiran aircraft being used to provide Stage-II training to IAF pilots. For pilots to acquire the skills to fly sophisticated combat aircraft they need to first graduate on a trainer that introduces them to a state-of-the-art cockpit environment. Thus was born the idea for the IJT. The aircraft has cutting edge Active Matrix Liquid Crystal Display (AMLCD) and a Head UP Display (HUD) that will ensure a seamless transition of the pilot to advanced jet systems. The large canopy coupled with stepped up seating for the rear pilot and sharp drooping nose provide excellent all round field of view.

The IJT is a product of contemporary design & analysis tools, highly sophisticated computing systems, state-of-the-art structural laboratories, manufacturing facilities & an exceptional pool of highly competent work force.

Light combat aircraft (LCA)

LCA is a light multi-mission agile fighter aircraft meant to replace the ageing fleet of MiG 21 aircraft. The LCA project conceptualized in the late seventies and formally launched in 1984 is managed by the Aeronautical Development Agency (ADA) with HAL as the Prime Contractor accounting for an overwhelming majority of design and manufacturing tasks. The flight test phase of Tejas was initiated on 4 January 2001 with the first flight of the first Technology Demonstrator prototype (TD-1).

The Naval version of LCA has some more challenging technological features when compared to the basic LCA IAF version. Some of these include the Leading Edge Vortex Controller (LEVCON), Ramp take-off, Telescopic Landing Gear designed for a very steep sink rate and the Arrester Hook system for deck recovery.

The different variants of LCA are:
  • Fighter Version
  • Trainer Version
  • Naval Version

LCA MK II (Airforce & Navy)

In order to improve the performance, to make system improvements and capability enhancements and to address maintainability aspects the Design & Development of Mk-II variant of both the Air Force & Naval versions of the LCA have been taken up. The Mk-II version of the LCA will feature a higher thrust engine (GE F414 IN S6), upgraded Avionics, Unified EW Suite with conformal antennae, retractable In-flight refueling probe, etc

Fifth generation fighter aircraft (FGFA)

Indo-Russian joint design & development of a highly advanced stealth fighter aircraft. Designed to serve as the mainstay of Indian Air force for the next few decades. Features include stealth, swing role capability, internal carriage of stores, super cruise and ultra maneuverability. Can carry a broad range of weapons and has a lethal radius of action for effective penetration and destruction of enemy defence. Will pitchfork Indian aircraft design capabilities to an unprecedented level of sophistication and technological fineness.

Multi role transport aircraft (MTA)

Twin engine aircraft with state of the art FBW, FADEC & Glass Cockpit capable of switching roles ranging from cargo transport to Air Ambulance. Capable of cruising at 850 kmph with maximum range of 2500 km under maximum pay loads of 18.5T with calendar life of 35 years. Designed for operating at elevated airfields and capable of high and low altitude drop operations. Execution of Design & Development of the aircraft through Multirole Transport Aircraft Limited (MTAL) JV.

Hindustan turboprop trainer (HTT 40)

HTT 40 Basic/ Primary aerobatic trainer aircraft to meet the Stage-I (ab-initio) training needs. The aircraft will employ classical straight tapered wing platform and all metal construction. The seating is tandem and cockpit will be air conditioned and pressurized. Zero-Zero ejection seat will be provided in each of the cockpit. The aircraft will be configured around a proven turboprop engine and will have retractable undercarriage. Flight controls will be manual. Avionics system would comprise glass cockpit with modern avionic suite
