TEST FACILITIES FOR AIRCRAFT PRODUCTS

Endurance Test Rig (ETR) consists of a 250 kW DC motor coupled with a 1 : 9.375 step-up gear box connected to the test gear box through a power take off shaft and loaded on its output pads through water brake dynamometer. A Programmable Logical Controller (PLC) ensures automatic control of test sequence with in-built safely interlocks. Customised Data Acquisition System (DAS) monitors and stores test data parameters for offline analysis and report generation.

Attitude test rig is used to test the performance of gearbox by simulating the aircraft maneuvers like pitch and roll as per user specifications. The drive is provided by the pump in the gearbox instead of PTO shaft. The pump performance parameters are checked at various attitudes namely low oil pressure, delivery pressure and flow rate at outlet.
EMI/EMC Test Facility

ENVIRONMENTAL TEST FACILITIES

AFVs encounter a wide variety of hostile and hazardous natural and induced environments during storage, field deployment and trial phases in their life cycle. These environments include extreme hostile climatic conditions, atmosphere precipitation, tropical exposure and cross country operations in different terrains and weather conditions. Besides these environments, the operative conditions induce shock, vibration acceleration and intensive heating during running and firing exercises on the AFVs. During this period the AFVs have to operate with the high degree of performance coupled with optimum reliability.
As AFVs are optimally designed with small margins of safety with close design tolerances it is essential that they are exhaustively tested in a realistically simulated environment in which they operate. Prior testing and approval leads to optimum performance and also avoid costly failures. Malfunction of AFV electrical and electronic equipments may lead to even mission failure or total loss of AFV system. It is practically not possible to prove the total AFV in actual environmental condition due to time and enormous cost involved. Hence all AFV electrical and electronics system are subjected to rigorous environmental tests as prescribed in Joint Services Specification No 55555. These performance evaluation and reliability tests are prelude to clear the equipment for total evaluation and service use.
