DRDO Chief says LCA Tejas is best in Class Aircraft


India’s very own Light Combat Aircraft, Tejas, with the help of domestic technology and developments has managed to become one of the best in class aircraft. Its combat stability under intense and problematic conditions is also a useful feature says S Christopher, Chairman, Defence Research & Development Organisation (DRDO).

The statements were given during the third International Federation of Automatic Control (IFAC), an International Conference on Advances in Control & Optimisation of Dynamical Systems (ACODS 2018).

Tejas is also equipped with the rules- based Artificial Intelligence combined into its Flight Control System (FCS) which ensures a ‘carefree handling’ by the pilot, he added. Tejas is also a combination work by the Aeronautical Development Establishment, Bengaluru, and HAL, responsible for its development.

Meanwhile, flight speed is needed to keep a check on or it will result into a loss like aircraft such as the MiG-23/27 or Jaguar aircraft at lower speed.

A bigger problem still persists for the pilots regarding the control of its longitudinally unstable air frame, leading to disturbances of even small magnitude that eventually delayed and resulted into longer period for the Tejas development programme.

Also a Secretary himself of the Department of Defence R&D, Christopher suggested adding more features and capabilities while moving ahead with the increasing requirements of aerospace and defence projects.

The control system though have a variety of applications ranging from aircraft and submarines to missiles, a better initiative in terms of guiding scheme and algorithms with futuristic weapon systems would be an added benefit as it will create a technologically smart and powerful system he said.

The conference which is being organised by DRDO is getting a participation of more than 500 scientists, academicians, industry partners and students.

G Satheesh Reddy, Scientific Adviser to the Defence Minister and DG (Missiles & Strategic Systems) also spoke about the future of aerospace and defence systems explain the importance of miniaturised avionics and smart sensors in existence.

The aerospace vehicles like fighter aircraft, missiles and launch vehicles are needed to be worked on with guidance for the algorithms to be developed properly for the future generation.


A line of globally renowned scientists like N.V. Kadam and S.K. Ray, former senior scientists of the APJ Kalam Missile Complex, were appreciated for their lifetime contributions in the field of control and guidance.

Also joined them experts like P.K. Menon, Chairman & CEO, Optimal Synthesis Inc., Reza Moheimani, University of Texas, Sarah Spurgeon, University College of London, and Min-Jea Tahk, Korea Advanced Institute of S&T were spoken to during the international conference, addressed by Frank Allgower, President, IFAC Austria (Stuttgart University, Germany) in inauguration function.
