DRDO TEST FACILITIES FOR ARMORED VEHICLES :PART 1

CVRDE is responsible for performance evaluation of automotive systems developed for AFVs. Various test facilities created in CVRDE helped in design verification of automotive systems in simulated field conditions. The performance of the mechanical systems is thoroughly validated by selective performance, endurance and acceptance tests before integration in AFVs for the field trials. CVRDE strives to complete the product development cycle of AFVs by achieving excellence in performance evaluation.

This month series will tell you about various test facilities for AFV developement of the country.

870 KW ENGINE TESTING FACILITY

The facility consists of test equipment :

  • eddy current dynamometer
  • throttle actuator
  • dyno controller measuring equipment such as load and speed measurement system, fuel consumption meter, blow by meter, smoke meter, air mass flow meter and host of sensors for temperature, pressure and flow.

The facility has been extensively used for validating the improvements carried out on the base engine V 46.6 of T-72 vehicle for power enhancement from 780 hp to 1000 hp. Also high coolant and lubricant temperature simulation testing is enabled through installation of three way control valves which contributed greatly in high temperature endurance test.

SPECIFICATION OF RIG: 

1500 KW ENGINE TESTING FACILITY

The facility consists of test equipment comprising :

  • hydraulic dynamometer
  • throttle actuator
  • dyno controller
  • measuring equipment such as load-cum-speed measurement system, fuel consumption meter, blow by meter, smoke meter, air mass flow meter and host of sensors for temperature, pressure and flow.

Combustion phenomenon is studied by utilising high speed 16 channel indicating system for crank angle and time-based measurements of combustion pressure, low pressure phenomenon at intake and exhaust manifolds.

Injector needle lift sensor is also provided to correlate the combustion curve with injection timing and further performance analysis.

The facility has been integrated with interfaces to carry out running-in and performance test of Arjun MBT, MB838, 1030 kW engine after overhaul for the first time in India.
