DRDO Nishant
The DRDO Nishant is an unmanned aerial vehicle (UAV) developed by India's Aeronautical Development Establishment (ADE), a branch of Defence Research and Development Organisation (DRDO) for the Indian Armed Forces. The Nishant UAV is primarily tasked with intelligence gathering over enemy territory and also for reconnaissance, training, surveillance, target designation, artillery fire correction, damage assessment, ELINT and SIGINT. The UAV has an endurance of four hours and thirty minutes. Nishant has completed development phase and user trials. The 380 kg (840 lb) Nishant UAV requires rail-launching from a hydro-pneumatic launcher and is able to be recovered by a parachute system. Launches at a velocity of 45 m/s are carried out in 0.6 second with 100 kW power and subsequent launches can be carried out in intervals of 20 minutes. The Mobile Hydro-Pneumatic Launcher (MHPL) system mounted on a Tatra truck weighs 14,000 kg (31,000 lb) and boasts of a lif ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Silicon Carbide
Silicon carbide (SiC), also known as carborundum (), is a hard chemical compound containing silicon and carbon. A semiconductor, it occurs in nature as the extremely rare mineral moissanite, but has been mass-produced as a powder and crystal since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Large single crystals of silicon carbide can be grown by the Lely method and they can be cut into gems known as synthetic moissanite. Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and Cat's whisker detector, detectors in early radios were first demonstrated around 1907. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both. Natural occurrence Naturally occurring moissanite is found in only minut ...

DRDO AURA
''Ghatak'' (pronounced: gʰɑːt̪ək) is an autonomous jet powered stealthy unmanned combat air vehicle (UCAV), being developed by Aeronautical Development Establishment (ADE) of the Defence Research and Development Organisation (DRDO) for the Indian Air Force. The design work on the UCAV is to be carried out by Aeronautical Development Agency (ADA). ''Autonomous Unmanned Research Aircraft (AURA)'' was a tentative name for the UCAV. Details of the project are classified. The Ghatak UCAV will have internal weapons bay for carrying missiles, bombs and precision-guided munitions. Its design will be based on flying-wing concept, and will be powered by a turbofan engine. The first flight of a scaled down testbed was carried out in July 2022, and that of a full scale prototype is expected in 2025. Description The Ghatak is an autonomous jet powered stealthy unmanned combat air vehicle (UCAV), being developed by the Aeronautical Development Establishment (ADE). It was initially c ...

DRDO Rustom
The DRDO Rustom (English: ''Warrior'') is a Medium Altitude Long Endurance unmanned air vehicle (UAV) being developed by Defence Research and Development Organisation for the three services, Indian Army, Indian Navy and the Indian Air Force of the Indian Armed Forces. Rustom is derived from the NAL's LCRA (Light Canard Research Aircraft) developed by a team under the leadership of late Prof Rustom Damania in the 1980s. The UAV will have structural changes and a new engine. Rustom will replace/supplement the Heron UAVs in service with the Indian armed forces. Design and development Rustom-1's basic design is derived from the NAL light canard research aircraft (LCRA). The aircraft has been named after Rustom Damania, a former professor of IISc, Bangalore who died in 2001. DRDO decided to name the UAV after him because it is derived from National Aerospace Laboratories' light canard research aircraft (LCRA) developed under Rustom Damania's leadership in the 1980s. With the Rusto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakshya PTA
Lakshya ("target" in Sanskrit) is an Indian remotely piloted high speed target drone system developed by the Aeronautical Development Establishment (ADE) of DRDO. A variant ''Lakshya-1'' is used to perform discreet aerial reconnaissance of battlefield and target acquisition. The drone remotely piloted by a ground control station provides realistic towed aerial sub-targets for live fire training. The drone is ground or ship launched from a zero length launcher and recovery is by a two-stage parachute system developed by ADE (DRDO), for land- or sea-based recovery. The drone has a crushable nose cone, which absorbs the impact of landing, minimizing damage. The flight path may be controlled or pre-programmed, based upon the type of mission. Development The requirement for a pilotless target aircraft (PTA) arose in 1976. Feasibility studies were carried out by ADE to provide for a target system that met the requirements of all 3 services of the armed forces. An Inter Services Qual ...
