The Dynamics and Aeroelasticity Group within the Airframe Directorate of the Aeronautical Development Agency (ADA) plays a pivotal role in ensuring the structural integrity and performance of India’s indigenous combat aircraft. The group is tasked with conducting structural dynamic, flutter, and aeroelastic response analyses, as well as coordinating testing activities for the Light Combat Aircraft (LCA) Airforce Mk-1, LCA Airforce Mk-2, and the Advanced Medium Combat Aircraft (AMCA) programmes.
Modern aircraft design demands rigorous analysis to ensure structures can withstand dynamic loads and remain free from vibration and flutter across the entire flight envelope. For the LCA Mk-2, this process is particularly critical due to the inclusion of an additional control surface—a canard—which requires detailed aeroelastic characterization to validate its performance and safety.
To accelerate the dynamic analysis process for the LCA Mk-2 and expedite its certification, the Dynamics and Aeroelasticity Group has proposed outsourcing a portion of the flutter and dynamic analysis as a work package. This strategic move aims to enhance efficiency while maintaining the high standards required for military aircraft certification.
As part of the outsourcing initiative, ADA will provide the following inputs to support the analysis:
- Finite Element (FE) Model of the full aircraft, enabling detailed structural simulations.
- Mass Properties Data, critical for accurate dynamic and flutter calculations.
- Flight Envelope Data, defining the operational boundaries for analysis.
- Ground Vibration Test (GVT) Data, offering empirical insights into the aircraft’s dynamic behavior.
