HAL entered into an agreement with Elbit Systems Electro Optics Elop Ltd, Israel, for supply of Digital Overhead Head Up Display Systems (DOHS), during the recently concluded Aero India-2021. The Digital Overhead HUDs will be initially manufactured in existing facility of HAL’s Division at Korwa. A dedicated facility will be augmented progressively in proportion of manufacturing volume.

HAL and Elbit Systems have envisaged a mutual co-operation to upgrade its technological base and acquire high end technology on Digital Overhead HUD System which is primarily used in transport aircraft worldwide. The Digital Overhead HUD with modern optics provide sharp brightness, larger field of view and larger head motion box. Earlier, HAL’s Korwa Division entered into licensed Transfer of Technology agreement with ELOP Electro-Optics Industries Ltd, Israel for setting up the D-level maintenance and manufacturing facilities of CRT based HUD (front) in the year 2000 and 2003, respectively. More than 500 HUDs have been supplied for various Indian platforms such as Su-30MKI, Jaguar and MiG-27M upgrade.

Hindustan Aeronautics Limited (HAL) and Mishra Dhatu Nigam Limited (MIDHANI) have signed a Memorandum of Understanding (MoU) for development and production of composite raw materials. This is the first time that such an MoU has been signed for composite raw materials. The MoU was signed by Chairman and Managing Director, HAL, R. Madhavan and Chairman and Managing Director, MIDHANI Dr S.K. Jha in the presence of other senior officials.

Madhavan said composites are one area where HAL will collaborate. Composites raw materials, mainly in the form of prepregs used in platforms like Light Combat Aircraft (LCA), Advanced Light Helicopter (ALH), Light Combat Helicopter (LCH) and Light Utility Helicopter (LUH) are currently imported.

Jha said that this is the major step forward in the area of composite materials. The HAL is not only taking care of frontline aircraft production but also raw materials. There is no equivalent proven Indian approved/qualified supplier for various types of prepregs (carbon, aramid, glass types, etc) for the aircraft applications. This creates dependency on foreign Original Equipment Manufacturers (OEMs). Aligned with “Aatmanirbhar Bharat” initiative, efforts need to be made to develop and manufacture such prepregs in India through collaboration, he added.

The usage of composites in the aerospace is going to exist and increase, particularly for fighter aircraft/helicopter because of its inherent advantages over metallic raw materials. In addition, similar requirement exists for other aerospace and defence programmes, including those of Indian Space Research Organisation (ISRO), Defence Research Development Organisation (DRDO) and National Aerospace Laboratories (NAL).
