Vibrations and Structural Dynamics Test Facility (VSDTF)

Experimental structural dynamics is a very important subject for certification and modification of aerospace structures. Using the equipment, the dynamic behavior of the structure, in-terms of natural frequencies, mode shapes and damping values are obtained experimentally. These test results would be used to compare, update and fine tune the mathematical model of the structure. Different types of excitations to the structure, such as, impulse excitation using instrumented hammer and forced excitation through electro-dynamic shakers can be applied to get the dynamic properties of the structure.

Flight Simulation Test Facilty (FSTF)

Flight simulation laboratory hosts an engineering simulation based on simulink implementation of the equations of motion. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into flight dynamics and handling qualities. The use of flight simulators for training in complex and potentially dangerous situations (e.g. engine failure, systems failure, structural damage etc) is a critically important area in aircraft development.

In addition to the cockpit interfaced simulator, the flight simulation laboratory contains three PC based flight simulator. Of these, one is configured with hardware to simulate fighter type aircraft controls, another is configured to simulate general aviation type aircraft controls, and the third is configured to simulate a glider type aircraft controls. These three simulators have provision to incorporate the dynamics of other aircraft.

Experimental Aerodynamics Test Facility (EATF)

Aerodynamics is the epicenter of Aeronautical Engineering. Though the wave of Computational tools is still on a climb, Experiments are an irreplaceable tool to understand real world Aerodynamics. Experiments facilitate in understanding the real Physics by conducting tests on geometrically scaled models using the concept of dynamic similarity. Various techniques used in Experimental Aerodynamics include free flight tests, rocket sledge, Para-dropping, scaled model flying, wind tunnel testing.

Wind tunnel testing is the most viable and versatile tool to conduct the aerodynamic experiments. Department of Aeronautical Engineering at IARE is in possession of a low speed subsonic wind tunnel and all necessary allied equipment /instruments required for executing a glitch free environment academic research.
