Extensive tunnel tests have been carried out to generate aerodynamic data on frozen configuration of LCA on different scale models in
various tunnels, in the entire flight envelope, both in India and abroad. The range of low speed and high speed wind tunnel tests include: - Force and moment tests
- Air-intake tests
- Component load tests - Wing and Fin loads, Control surface, hinge moments, Air brake loads, Store carriage loads etc.
- Dynamic derivative tests(forced and free oscillations)
- Ground effect studies
- Pressure measurements
- Spin tests
- Store carriage & separation studies
- Flow field measurements at Air Data Sensor location
All the wind tunnel models for the whole range of tests have been designed and fabricated within India (NAL/HAL/ADA/CMTI). Also, several special test rigs balances, high speed data acquisition systems, mass flow control units, dynamic distortion rakes etc. were developed for these tests within the country. |
