IAF's military transport aircraft IL-76

NEW DELHI (PTI): Enhancing the Army Special Forces' capabilities to airdrop combat vehicles and heavy equipment, DRDO has developed a heavy system which can drop loads up to 16 tonnes from the IL-76 transport aircraft using parachutes.

"A 16-ton capacity heavy drop system (HDS) consisting of a platform and a highly advanced system of parachutes to drop loads consisting of military stores such as vehicles (including BMP class), supplies and ammunition from IL-76 heavy lift aircraft has been designed and developed and demonstrated," DRDO spokesperson Ravi Gupta said in a release.

Three prototypes of the system developed by an Agra-based DRDO lab have been realised and two successful drops meeting the performance parameters have been demonstrated, they said.

On the development, DRDO chief Avinash Chander said, "The system offered 'drop and drive' capability and once inducted, the system, a force multiplier, will considerably enhance the capabilities of armed forces."

P-7 heavy drop system (P-7 HDS), paradropped as composite unit termed as 'Load', has been developed for paradropping military stores/equipment such as military vehicles and ammunition trolleys from IL-76 aircraft and comprises two main sub-systems namely Platform sub-system and Parachute Sub-system.

The platform has a set of removable wheels which provides transportability for load to be taken to the airfield by means of towing it behind a suitable vehicle once the load is prepared at the distantly located unit.

These parachutes reduce the descent rate to desired speed at touchdown.

On impact with ground, parachutes are released by automatic disengage unit (ADU) to avoid dragging and toppling of load due to high speed winds.

The design features built in the system ensure aircraft safety during the separation of such a large body in a foolproof manner as well as smooth deployment of parachutes and landing of load at pre-designated target point.
