DRDO Lakshya | Lakshya II | Indian Defence Avionics

LAKSHYA, a pilot-less drone or a vehicle that doesn’t need any person to operate. It is a high-speed drone system, therefore it proves to be a great success for the defence force. Aeronautical Development Establishment, made this indigenous drone system. In addition, the ADE is a branch of the Defence Research and Development Organisation. DRDO Lakshya holds an introduction in 2000. Further, a total of 23 Lakshya drone aircraft is being in service for the defence force.

Another variant of the Lakshya is going to develop by the ADE. The variant name is Lakshya-2. Thus, the Lakshya-2 has some advanced features that made it superior to other aircraft and it can fly at extremely low altitudes between 15 m and 20 m for testing guns and missiles. On the other hand, the Lakshya-2 fitted with electro-optic cameras. In addition, it has digital computers and the SATCOM data link to perform difficult missions. The first flight of the Lakshya Aircraft took off in 1985. The length of the Lakshya drone is 2.38 m. Its wingspan is 3 m. The Lakshya can carry weight up to 705 kg. The aircraft has a single-engine and its range is 150km.

Reason Behind Development of DRDO Lakshya

Moreover, the reason behind making the Lakshya aircraft is to attack safe either from land or sea through a zero launcher. Additionally, it comprises a dual-stage parachute system. The idea of a pilot-less aircraft proposed in 1976. ADE organized a study of PTA to meet the requirements of the armed forces. The government approved this proposal in $3.8M to ADE in September 1980. In addition, $1M also has been given to Hindustan Aeronautics Limited in September 1980 to develop the vast turbojet engine for the PTA. The very first flight of the Lakshya aircraft took off in 1985. A total of 4 trials have done of which 2 were successful and the other two failed.

The Lakshya-2 aircraft introduced to the world in July 2003 and, therefore, the flight trials of the aircraft held in April 2003. Further, the only flight test of the aircraft took off in December 2010.

Features of DRDO Lakshya

DRDO Lakhsya has a breakable nose cone, infrared sensor and synthetic aperture radar. The DRDO Lakshya consists of wing pylons to train crews of anti-aircraft guns and missiles. Hence, an indigenous rocket booster weighing up to 145 kg fitted with the aircraft to have a smooth flight. The aircraft suite in Lakshya also comprises electronic flight control (FCE), electromechanical actuators, vertical gyro, AMDI and CW doppler. The AMDI tests a poor projectile distance and evaluates the artillery crew’s success and skill.

The Lakshya is powered by a unique 3.7kN thrust turbojet PTAE-7 engine. HAL’s engine in Bangalore is planned and manufactured. The turbine is 1.27 m in length and 0.33 m in diameter, also its rough weight tends to be 65kg. The Lakshya can be operated by pre-programmed hardware and software systems from the ground control station (GCS). Five drones can be controlled at the same time by each GCS. It also provides planning and simulator equipment for planning, validating and performing the missions of the vehicle. The instructions can be conveyed by a UHF or L-band frequency from the GCS to the engine. Therefore, tt the pace of 25m/s, the Lakshya will ascend and the aircraft’s top speed is 857 kmph. Bandwidth and operation limits are respectively 150 km and 9000m.

Lakshya 2 & Current Updates

Lakshya-2 is an advance variant of Lakshya-1, less target aircraft pilot also, it is a focus of radar-guided systems, and heat-seeking systems for the surface to air rockets, air to air rockets. It also has a Scoring system that can correctly calculate the missing gun gap. This innovative PTA offers improved endurance, independent and low-level volume, flight and automatic test equipment. It has a digital aircraft control system integrated, a low-level flight capability, passive RCS increase for Lakshya on both front and side aspects, increased Lakshya aircraft with an active repetitive BVR missile system and a capability to fly two aircraft simultaneously from one GCS, automated test equipment. The system is also equipped with an integrated digital flight control unit for firefighters. Technology Transfer to L&T was granted. Lakshya Missile Delivery Configuration is also built-in combination coordinates for weapons delivery.

Furthermore, the Lakshya-II was again got a chance to take off on the Integrated Evaluation Range (ITR) on 27 January 2012 in the forward variant of the pilotless target aircraft (PTA). At the launch complex-3 of the ITR, some 15 km from here, was also conducted the 11th air demonstration of a mobile vehicle. The whole flight was pre-scheduled and was entirely successful, according to defence sources. Also, ADE, a leading DRDO laboratory specializing in UAVs and Flight Control Systems, from Bangalore, is designed and developed by Lakshya-II. On 23 August 2012, the Air Force variant of Lakshya-1 got into recheck to search for the validity and span of its engine. Therefore, the Lakshya-2 air force successfully flew from the integral test range of Odisha for 30 minutes on 16 March 2017.
