Rustom (English: Warrior) is a Medium Altitude Long Endurance unmanned combat air vehicle (UCAV) 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.[2] Rustom is derived from the NAL's LCRA (Light Canard Research Aircraft) developed by a team under the leadership of late Prof Rustom B Damania in the 1980s. The UAV will have structural changes and a new engine.[3] Rustom will replace/supplement the Heron UAVs in service with the Indian armed forces.[4]

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. As a Parsi, Rustom himself was named after the Persian general Rostam Farrokhzad in the Sassanid court who fought the Muslim Arabs.[5] 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.[6]

With the Rustom MALE UAV project, DRDO intends to move away from traditional ways of developing products whereby laboratories under DRDO, like the Aeronautical Development Establishment (ADE), which is involved in this project, develop and finalise the product and transfer technology to a production agency.[7]

DRDO will follow a practice of concurrent engineering where initial design efforts also take into consideration production issues, with the production agency participating in the development of the system right from the design stage. The agency will also follow up issues related to infrastructure and expertise for the product and its support, thereby overcoming time delays in crucial projects.[8]

Rustom-1 which bears an uncanny resemblance to Rutan Long-EZ designed by Burt Rutan has a wingspan of 7.9 metres[9] and weighs 720 kg,[9] will be launched by the conventional method and not the launcher as in the case of the DRDO Lakshya. Rustom will be able to see the enemy territory up to a distance of 250 km and carry a variety of cameras and radar for surveillance.[10]

Rustom-H, built on a different design, owes nothing to Burt Rutan's Long-EZ design. It is a Medium-Altitude Long-Endurance (MALE) Unmanned Aerial Vehicle (MALE UAV), a twin engine system designed to carry out surveillance and reconnaissance missions. Rustom H will have a payload capacity of 350 kg.[7]

The range of advanced technologies and systems include the following:[9]

  • Aerodynamic configurations, High aspect ratio wing, Composite airframe integrated with propulsion system, De-icing system for wings
  • Highly reliable systems with built-in redundancy for flight critical systems like flight control and navigation, data links, power management, - and mission critical payload management system
  • Digital Flight Control and Navigation System, Automatic Take off and Landing (ATOL)
  • Digital communication technologies for realising data links to control and operate the mission and relay UAVs
  • Payloads with high resolution and precision stabilised platforms.

Variants

There will be three variants of the Rustom UAV.[11]

  • Rustom-I: Tactical UAV with endurance of 12 hours (based on NAL's LCRA which was inspired by Burt Rutan's Long-EZ)[7][12]
  • Rustom-H: Larger UAV with flight endurance of over 24 hours (completely different design from Rustom-1), higher range and service ceiling than Rustom-1.
  • Rustom-II: An unmanned combat air vehicle based on Rustom-H model. It is often compared with Predator drones by Indian scientists and media.[7][11][13][14]

Current status

The Indian government has allowed the development of the Rustom MALE UAV project in association with a production agency cum development partner (PADP). The ADE officials indicated that the requests for proposals (RFP) would shortly be issued to four vendors which are the Tatas, Larsen and Toubro, Godrej and Hindustan Aeronautics Limited-Bharat Electronics (joint bid) who were chosen out of the 23 firms that responded.

Currently, negotiations are underway between these companies and the three Indian armed forces since the private majors are looking for support and commitment from them before they start executing any development and production plans. This is because of the fact that the chosen PADP will also have a financial stake in the Rustom project. The Armed Forces would also be asked to take up a financial stake and the Indian government may have to guarantee that a specific number of Rustom UAVs will be bought.[8][15][16]

Rustom-1

The first flight of Rustom-I UAV took place on 16-11-2009 at the Taneja Aerospace Air Field near Hosur. The demonstration resulted in the prototype crashing to the ground. Stated by the DRDO, the taxiing and takeoff was exactly as planned. Due to misjudgment of altitude of the flight, the on-board engine was switched off through ground command which made the on-board thrust developed to go to zero.[17] Despite the mishap, the state-owned Defence Research and Development Organisation stated: "The flight proved the functioning of a number of systems such as aerodynamics, redundant flight control, engine and datalink, which go a long way towards the development of a complex UAV."

The second "maiden" flight took place on 15th Oct 2010. In this test flight, the UAV flew for 30 minutes at an altitude of 3000 feet. The test was conducted in Hosur.[18] The Indian army was impressed with Rustom-1 and will use it as a MALE UAV.

Rustom-1 made its 5th successful flight on morning of 12 Nov 2011, flying for 25 minutes at 2300-ft AGL at a speed 100 Knots. It completed its 8th successful flight on 8 Dec 2011. It flew at an altitude of 6000-feet (max) and at a speed of 90 knots (max) during its 30 minutes flight near Hosur, claims DRDO. The highlight of the flight was that Rustom-1 was test flown with the 'gimbal payload assembly carrying daylight TV & Infra-Red camera for the first time. Good quality pictures were received from the camera in gimbal payload assembly.

The 14th Successful Flight of Rustom-1 was reported on 8 May 2012, with the attainment of about 11500 ft above ground level and speed of above 140 Kmph during 2 hrs 10 minutes of operation.[19]

Rustom-2

Rustom-2 is an unmanned combat air vehicle (UCAV) developed by India on the lines of the American Predator drones.[1][7][13]

In October, 2010 A senior DRDO official stated,

<templatestyles src="Template:Blockquote/styles.css" />

The American RQ-1 Predator is an obvious template for the Rustom program. We’ve built a credible unmanned flying platform. The way the Americans converted a robust surveillance drone into a combat drone is something we are confident we can replicate for the Rustom-H. It will have a great deal of mission flexibility. [..] [Work] is underway to define the weaponisation process.[11]

In February 2012, ADE Director P S Krishnan stated,

<templatestyles src="Template:Blockquote/styles.css" />

Designing of Rustom-2 has been completed, purchase orders have been placed and we are on schedule to fly for the first time in February 2014.[14]
