Study of Pressure Drop Effect on Airflow in Battle Tanks

Battle tanks are vehicles with a specific type of construction to meet demanding requirements of the military and operate in off - road and severe cross - country terrains. The operation of the prime mover (Diesel Engines of 400 to 700 Kw output) of the tank becomes difficult due to peculiarities of installation, such as cramped space, restricted opening for cooling airflow (8 to 15 Kg/s) and need for sustained operation on maximum torque and power conditions. The effect of high-pressure drop (300 to 500 mm of Water Gauge) due to such restriction on airflow is discussed in this paper with a specific example, and the remedial measures taken to modify the restriction along with the improvements (30% increase in airflow) achieved are elaborated.
